yep it is just a proof that if there are advanced aliens out there we are nothing but primates to them... in a face on fight we could find opportunitys for strikes... like finding a weakpoint in a system like in independence day where when they shoot their laser they are also vulnerable...
@user-dt7px5xp6zit takes decades to get from 1 galaxy to another at the speed of light and there’s thousands of galaxies, saying there is none with absolute certainty is idiotic
the manhole you're talking about was calculated to travel at around 66 km/s, which is something like 0.02% of the speed of light. and it is disputed if it actually left the Earth of if it disintegrated before leaving
@melwin2251 Unfortunately, it burned up before it left Earths atmosphere. We know for sure based off of the thermodynamics of the material made and the estimated speed recorded based on the frames and they used the speed on the lower side and it was still enough to burn up before it hit space :(
The stars are moving so you need do some serious math to predict where the planet of that star will be 42 years into the future. What if the star decreases it's speed for some reason? Even if it's a minor decrease, 42 years with that reduction and the distance in extremely far from the original one.
@@uafc1You can’t even calculate exactly where three point masses that are gravitational attracted in an isolated system will be in the future. You need to take it step by step, and the further out you go the more inaccurate. Imperceptible changes in the initial state will lead to a totally different outcome.
i was thinking ...since so many Aliens in Movies are monarchies with either a bug queen or some evil Emperor ....we may defeat them Communism ....ya know ...starting a good old french/Russian revolution and let the system destroy itself
Defenses would need to be pre emotive or in sabotaging the weapon itself. It’s not entirely feasible to intercept things moving at the speed of light as detection is impossible without ftl communications.
Unfortunately, the reality is that you can't defend yourself against attacks like these. There is no warning, and nothing you can do to stop the devastation. The only way to survive such an attack is to spread out in space, onto different planets and moons, in different stellar systems, and on artificial habitats in space. You could build a massive shield around Earth several km thick, but by that point you might as well build giant habitats in space instead. Such a shield would only reduce the damage of the electron beam, and be more of a harm than help if hit by a relativistic missile or giant laser.
If the aliens sent a message like "Surrender within 24 hours or face destruction" we could send a message back "Is that 24 hours in your time or our time?". Considering the distance involved, we could gain millions of years of extra time just by trying to sort that out.
uhhh, that dont make sense really, how do they check what our reply to their demand is, whether its a yes or a no, it would still take millions of years, so it cant be 24 hours, or alternatively it sometype of rocket that gets averted or stops when we reply, in which case, assuming it has enough intelligence and human knowledge to send us the threating message, then it would also reply to our question very quickly. wtf am i doing this is probably some 13 year old, i should go back to work
That still makes no sense bc our surrender message would still take millions of years to reach, obviously this time limited threat would imply they were close to us, not millions of light years away
That last one is actually pretty scary and these are just the things we can imagine today. Imagine the kinds of things an advanced civilization can create that we can’t even comprehend today.
Yup! It's like someone from the middle ages imagining a country-sized trebuchet to attack other countries, they would be unable to picture modern rockets and nuclear weapons.
That's where 'The Law of the Jungle' comes in. You don't know if an alien civilization is friendly, and it takes too long to find out. Therefore, the moment you learn about it, you'd better attack first. Otherwise, there will be no time for you to fight back.
@@caesural I dont know. They might have thought of rockets or explosions. Think about it. Lightning existed, and it made things explode, with fire and shit. So im sure some might have though about harnassing lightning or fire in throwable bombs or whatnot
Lesson 1: don't attack from your home base. Use another star as your attack base. If anyone retaliates, they attack right into your honeypot, revealing themselves. Welcome to interstellar war. Interstellar assassination with rockets: You don't have to go relativistic from your home base. Use light sails at the outskirts of your home star's corona to accelerate to 0.1c and go for a somewhat nearby white dwarf (not too near). Use the flight time to assemble the rockets underway. This should be possible totally unseen and costs just a couple of years more. That's totally unimportant since nobody knows about you anyway. At the white dwarf use an Obert maneuver going relativistic. The direction of attack is changed because of the gravity of the white dwarf (that's one of the reason's for the Obert maneuver, the other is the masking of the drive's radiation), masking the true origin of the attack and since the Obert maneuver is happening very near to the surface of the white dwarf everybody thinks this is a normal astronomical event on the surface of the white dwarf. You don't have a cooling problem because of the vicinity of the white dwarf since you have the technology to cool your rocket from the immense radiation of your drive which should be very much higher than the radiation coming from the white dwarf, so that's not a problem. If necessary you could even fake a real astronomical event using your antimatter. Nothing points to your home base. If anyone figures out anything it should be clear to them that the home base couldn't be have been the white dwarf and they remain silent.
You might be the first person writing about the strategies behind interstellar war and deception. You should add an edition on diplomacy. Perhaps a species might lie about their origin to hide their true location when making initial contact?
"When you attack, your grandchildren will be the ones to find out if you won." That is, unless the species that makes up a particular interstellar civilization happens to have a large lifespan.
@@psielementalor even more likely, they're post-biological. Either as a facsimile continuation of the original species or the AI system that replaced them.
And your great great grandchildren will be the ones who eat the retaliatory strike from that now long-dead system and the automated RKKV launch system your great grandpappy triggered.
@@Lucaaaaaaaaaaaas A species with a super small lifespan would most likely be too focused on reproducing to be able to make any significant advancements.
Alternatively, the Dune series... if you want the really weird, perverted answer. The answer is not in "the Spice." It's in the theoretical "Golden Path" which is essentially "spread far across the universe, mutate, evolve, and get so weird that even humanity as it exists can't predict what you might do."
Honestly, the UREB is probably the most terrifying concept this channel has ever discussed. A ghostly interstellar cancer laser that spares most inorganic resources. It also almost requires the weapon to be a good distance from the user's homeworld. So seeing where the beam is coming from only gives you a rough estimate of the user's home location. Such a dreadfully compelling weapon. I guess the one drawback compared to the other options is that it would take a hot minute to aim. But when your shot takes decades to reach target, I think taking a week to line up said shot can be forgiven.
There is a great Polish novel called "The Oldness of the Axolotl". The Earth was suddenly attacked by something similar to weapon number 3. Few thousand of peoples managed to survive by transfering their minds to electronic media (only half of the planet was destroyed in the first second, so some had up to 12 hours to prepare). The story takes place over hundreds of years and presents attempts to rebuild civilization and life while the main character slowly descends into madness.
There’s also a somewhat similar weapon utilized by what are referred to as “The Others” in _The Bobiverse_ series. Although, I don’t think it uses electrons, just gamma radiation and it’s not as long range.
An ''invasion'' or ''war'' probably only works if the two civilizations have roughly the same kind of technology. In all other cases, one will simply take over or destroy the other before they are aware of it.
My thought exactly. The idea of aliens destroying us is potentially possible but not realistic because they would have already done it if they had the weapons for it.
Two civilizations could have vastly disparate technology and the less advanced one could still kill the more advanced. They just have to by chance discover the advanced one first (or the more advanced one decides to ignore them) and be just technologically capable enough to build a weapon that takes out the other side in one shot.
@@wasd____ Good suggestion! In fact it reminds me of a series of science fiction novels written by Harry Turtledove. Central point: During WW2 an alien colony/invasion fleet arrives on Earth. By their own expectations, taking over Earth should be easy, an automated probe made pictures of Earth and its inhabitants during the Middle Ages. However the humans have technologically advanced since that time and they have other ideas....
They are billionaire funded and compromised. Ideologically they serve billionaire interests at the peril of our own planet, just like billionaires themselves
This is an amazing idea for a story in a movie/video game, where an alien species fires a weapon that takes so long that the ones who originally fired it are gone. And when humanity reaches the culprits, it's just someone else, completely innocent species, who doesn't even know what there predecessors did, and then it's the question of "is revenge even possible or relevant anymore"
@@hedgehog3180 that is I think based on the Sci fi trilogy Three body problem which brings the dark forest and intergalactic warfare to its most disturbing and hauntingly plausible conclusion
It is crazy to think that the Death Star, which to all of us seemed like the most insane weapon even for a universe with Light Speed travel, is actually the most reallistic weapon for an interstellar war.
@@menacingrock750 2 Corinthians 5:13-19 NLT - If it seems we are crazy, it is to bring glory to God. And if we are in our right minds, it is for your benefit. Either way, Christ’s love controls us. Since we believe that Christ died for all, we also believe that we have all died to our old life. He died for everyone so that those who receive his new life will no longer live for themselves. Instead, they will live for Christ, who died and was raised for them. So we have stopped evaluating others from a human point of view. At one time we thought of Christ merely from a human point of view. How differently we know him now! This means that anyone who belongs to Christ has become a new person. The old life is gone; a new life has begun! And all of this is a gift from God, who brought us back to himself through Christ. And God has given us this task of reconciling people to him. For God was in Christ, reconciling the world to himself, no longer counting people’s sins against them. And he gave us this wonderful message of reconciliation.
The book "The Forever War" by Joe Haldeman is an allegory for the Vietnam War but set in the distant future. The theme of "future shock" is a big part of the story. Humanity encounters an alien species who are basically in the "Old West" phase of weaponry and wipe the floor with them. A few hundred years later, relativistically only a couple years for the protagonist, the alien race has advanced way beyond humanity's capabilities and humans resort to a trench style warfare where they shelter under an energy shield and fight hand to hand.
Awesome book! I was thinking of it during this too. How each time the protagonist re-enter the fight society goes through all these changes because it's decades from one fight to the next
The interesting part is, that the moment you fire your flashy weapon, everyone who sees you doesn’t only know exactly where you are, but that you’re capable and willing to destroy them. So it’s likely that you might never find out if your weapon has hit, because you get destroyed by the people who witnessed you firing it…
Thats actually not true for the relativistic missile! If you shoot it out into interstellar space first many lightyears from the starting system and only then launch it at full speed towards the target nobody will be able to know for sure where it originally came from.
Already happened, i shot an Antimatter Missile at earth 127 years ago from a 183 light years of distance, then another civilization destroyed my planet, and made me reincarnate on earth so I will get destroyed by my own weapon
@@barnabasigari3109I’m sure the calculations could be made to track its trajectory, especially considering that the method you listed would be the logical precaution and so would be accounted for, though it would take a while
@@JoshBeck-z5m You can't track where it came from as long as multiple different small burns are used before igniting the antimatter drive, because it is possible to get to the same location in space from different starting points
@@jelybrd That just leads to "how do we exploit the people to get the biggest share of an infinite resource?" Just because something is infinite doesn't mean it won't be commodified and people will (as always) be exploited to bring that commodity to market.
Wasn't it 2 planetoids, one at each pole? I don't think bill got the mover plates efficient enough to move a gas giant. Especially not before they got the Casimir tech from the Other's wreck.
Could also just use a tiny amount of mass with even higher relativistic momentum to gravitationally destabilize the star and force a catastrophic outburst of solar material. That's what Mass Dots/Photoids from the Remembrance of Earth's Past (a.k.a. the Three Body Problem) trilogy do, and I suspect getting a tiny amount of mass up to that speed would probably be much easier than moving a planet-sized object around intact.
Saying the percentage of speed of light with that precision must've been an inside joke to Kurzgesagt, "Don't come close to Earth! Don't come close to Earth!".
There is something truly terrifying about the realistic possibility of getting instantly annihilated by an annoyed something we wouldn’t even know exists.
One thing not mentioned (but possibly implied) is that you cannot aim directly at the planet. All heavenly bodies are zooming through space, not stationary. Instead you would have to calculate the target's location at the expected time of impact and aim for that. It's extremely unlikely, but you would also have to ensure no planets/stars move into the path of the weapon before impact.
You only have to account for relative moment of the target planet in it's orbit. Since both solar systems are essentially neighbours in the same galaxy, all other motion (aka, rotation of the galaxy, traversal of the galaxy through space, etc) would be identical, and therefore not affect the projectiles trajectory (even if it's a beam without physical matter). Though now that makes me wonder whether that 'mutual lateral movement' might end up messing with the estimated % of lightspeed... because for every x km/s you are travelling sideways in parallel to your target, you have y km/s less maximum velocity towards your target, since the vector of your total movement cannot exceed c. Or can it, because you're still travelling at
its true that its hard to aim but you have literally "infinite ammo" and can shoot over a large area for a long time and rotate your laser on a grand-sacle. Maybe 1 Month of moving the mirrors arround. You will definetly make a hit.
@@Alblaka The mutual lateral movement does not mess with the speed, it's to be completely out of the equation, the only thing that matters is the relative velocity between the two bodies, if both are travelling at the same speed through space, that's not an issue Keep in mind that the speed of light is a measure in which the units are meters per seconds, which is space divided by time, both of which are relative to our frame of reference already, so while the light will always appear to be going away or towards you at the same rate in any frame of reference, distance and time are relative to the motion between the two observers
this is true, but a much easier option is to fire a weapon at the star instead. For example, a missile going at the speed of light striking into the Sun would likely cause a devastating solar flare or radiation emission that could destroy Earth. It is much easier to detect the location and movement of a star
@@higztv1166can confirm. I've never read a book that I had to put down to contemplate my existence for a few days. The amount of dread chixin liu can create with just words is seriously underrated
You guys should do a video on interplanetary warfare; like if there turned out to be an underground civilization on Mars all along, or if a fleet of Venusians emerged from the clouds. The distances are still vast, sure, but not as vast as interstellar space, so there'd be room for more "standard" weapons (kinetic strikes, EMPs, invasion fleets, etc.).
Fun Fact: if there are aliens watching us from around 78 light years away, they're watching WW2, if it's 65 million light years away, they're watching dinosaurs.
Wouldn’t they be watching twice that long ago as the light has to travel back again for them to know about it? They would be watching WW2 if they were 39 light years away, right?
I just love the moment at 07:00 when you see the old general from the nuclear war video and the scientists explaining the president what's happening with a toy rocket. This lasts about 2 seconds but it definitely made my day !
The math on the star laser and electron beam would have to be insanely accurate, because you need to shoot it exactly where the Earth will be in the galaxy when it arrives, not to mention however the laser will bend if it goes near any intense spacetime curvature like black holes and neutron stars. Even the smallest bit off course, especially in the the first half of its trip, and it’ll totally miss us by the time it arrives. I’m not sure it’s actually feasible, even for an advanced civilization. The relativistic rocket, which could constantly be recalculating and making extremely slight adjustments, would probably be the only way to have a chance at hitting the target.
Also, missing with a weapon like that broadcasts your position to anything and everything capable of detecting planet-killer weapons. And none of these are weapons that get you left alone.
As he said at the end; that if we see interstellar warfare we better stay out of it. This is most likely the scenario for other alien species too so it's probably a very slim chance others would intervene or try to be on the safe side by attacking the attacker, they themselves could in turn become a target aswell.
It gets even better for relativistic kinetic kill missiles: even if you were able to detect them before they hit and destroyed them before they reach your planet...you'll have potentially thousands, if not millions of near-light speed debris pummelling you in a shotgun blast pattern.
@@nil981If their technology is operating within so called interstellar space, I assure you that they would most definitely have a force repulsion capability
In a universe of millions of intergalactic civilizations it only takes a small fraction of them to be genocidal to be kind of a problem, so I guess it depends on how many are out there.
That is kind of the point of the video, actually. I mean, imagine the entire electrical grid of the US being used for 24 hours to power a laser aimed at Russia, with 24 hours of planned blackouts across the country to power it. It's only one day of disruption, but it's one day of a LOT of disruption. Now multiply that by a million. And also, in order to USE that energy, you have to build something practically the size of jupiter. Yeah, they're going out of their way to do it. Fair estimate. Considering how much wild excess the US currently puts into its military spending, though... Is it really that unbelievable to imagine a larger civilization using a proportionately similar amount of resources?
@@SubtleHawkNot really. If the universe was made up of millions of civilizations and only a fraction of them were genocidal then the hundred or so non genocidal ones nearby to singular genocidal one would likely keep them in check some how. Unless the genocidal one was leagues ahead in technology but if that was the case then none of the others would be around them. If they were genocidal they likely wouldn't even bother to invade. Just one day earth would be hit by a relativistic weapon and it would be over for us. They wouldn't even have to know we were here. They could have just detected signs of life from when the dinosaurs were around and launched their weapons millions of years ago. Course if it was relativistic it would likely have been reached sooner but that still means they could detect and kill earth at any point in the distant past. The fact that earth is still around is a good sign that there are no genocidal aliens anywhere remotely close by.
The universe could actually be really small to something we don't know about. Things like physics and distance could also be completely arbitrary values that can change on a whim. We might wake up one day and find that interstellar travel is suddenly easy and never know why things changed.
Liu Cixin has a great book/audiobook series about this, I highly reccomendations it. Spoilers: a major theme of the books is the "dark forest" concept, where all you have to do is broadcast the coordinates of a star out into space, and it will be destroyed. This is because his solution to the fermi paradox: as soon as life in the universe reveals itself, the most powerful and reclusive aliens will destroy it as soon as possible in order to survive. Since there is always going to be a social and technological barrier between any 2 alien worlds, the only way a species can thrive is to eliminate any other form of life before it surpasses them in technology. Perfectly transparent communication of intention is always impossible, so each species must assume the worst and take steps to eradicate each other. Like another comment said, the ultimate moral is that each party must take a leap of faith (against all logic and reason) to trust each other. Otherwise the universe continues to be an endless arms race untill its complete and total collapse.
@@planitery7857 Not too sure! I mean, Adobe After Effects has indeed very powerful tools that can give the illusion of a 3D animation when it's actually a 2D animation, but 4 years ago when they revealed how they make their videos and they mensioned that they started experimenting with cinema 4D recently at that time! But on the other hand Adobe After Effects does have a new 3D feature that makes really good 3D animations as well so it could still be an entire possability that they used adobe after effects for the 3D
But they could've mentioned the outcome of another interstellar conflict from _A hitchhikers guide to the galaxy,_ due to a miscalculation of scale the entire invading space fleet was inadvertently swallowed by a small dog.
The funky thing about interstellar warfare is that if you want to eradicate all life and plan to send troops, you have to accelerate and then decelerate large vessels to near relativistic speeds Not sending any troops means you can send a way smaller object and there is no need to decelerate at all.
To be fair, the same holds true on earth as well. A missile attack is certainly landing faster in location X than any type of troop transporter. Granted regular communication is much easier here on earth, aka the conflict might be avoided.
Nobody is going to bother bringing troops over to invade. There is nothing precious enough on larger planetary bodies, you won't find easier accessible in asteroids or moons.
What if you are just a really advanced civilization that can traverse space-time with the ability to accurately model evolution over a couple million years and you send a biological weapon in the form of a single cell filled asteroid to destroy the native life and spawn a creature that invades and spreads across the entire planet while destroying the habitat and atmosphere with poisonous gas and radiation?
The three body problem is the greatest series of novels I have ever read to do with alien invasion. Read this series and instantly double your perceived imagination of space. It's that mind blowing. I highly recommend it.
I’m impressed by how much your animation skills have improved specially the 3D effect and I love how realistic in an idealistic way you guys are thank you for posting! I love this channel and I always have
Sad news for the Smorpians: During the time that you see, that’s its position 42 years ago; and when you shoot, the Sun, along with Earth and other planets would have moved by ≈291.3 billion km, and when you fire the missile, it would need to travel for another 42 years, so when you missile reach, the solar system would have moved by another ≈291.3 billion km, so you’ll be off ≈582.7 billion km from the target. Even if you somehow manage to aim at Earth, there could be celestial bodies in the way, so it could block, reflect, distort, bend, … the trajetory. Even if there aren’t any objects in the way, if an object has a magnetic field, it could deflect the paths of the electrons. Even if you manages to hit Earth with electrons, the magnetic field would deflect them Using that, interstellar war is not easy because stars, planets, asteroids, comets, and even black holes are moving. Because of that, a star system would have moved enough to dogde any of those weapons. Even if it doesn’t miss, celestial bodies that are moving could reflect, block, distort, refract, bend, … the weapon’s trajectory. Even if there aren’t anything in the way, if an object has a magnetic field, it could deflect the charged particles, even if the aren’t anything or magnetic fields, if the planet/star/moon has one, it would deflect them. So yeah, i think we, along with other aliens (if existed) will never get hit by any of those weapons
Just remember, every weapon of existential dread in this video was dreamed up in a human brain. We're all just sitting around dreaming about how we might someday kill the alien life we havent even met yet. We are the existential threat. HFY.
True but this just means that peace with alien life is a pipe dream. Better to genocide first and just take the whole universe(or as much as we can) for humanity ask questions later.
First a 1 hour video, then another 12 minute video, you guys are on fire, greetings from Pakistan as a fellow animator, I know how difficult it is to make animations, combined with great excecution of script and concept, you guys excel at both, Keep it up
An amazing video, as always, but imagine you’re just hanging out in space and a giant green beam you *didn’t* see incinerates you because a war that has nothing to do with you is happening
There's also no reason to be quiet like kurzgesagt keeps suggesting. Any being advanced enough to harm us from dozens of lightyears away is already aware that we exist and has been for a while. We are already almost able to see the atmospheric composition of exoplanets so imagine what such an advanced civilization could tell when turning their telescopes on us.
This video accurately describes one of the reasons why the Dark Forest theory is extremely unlikely to be correct. If any one galactic civilization attacks another with a superweapon such as this, they will pretty rapidly get dogpiled by all the others. It is in everyone's best interest to play relatively nice with others.
Unless they do it to everyone else first; nobody would know, all adversaries would be extinct as soon as they are identified,before they can react and before they can issue any warning to anyone else (and, even then, these others would have been targeted already anyways). In theory, an extremely aggressive belligerent alien civilization could be sterilising any planet with anything living or intelligent enough as soon as they detect them... And by the time anyone else is aware they'd be gone or targetted beyond reaction time already
Only for that to happen they will have to be aware of each other, they will have to be culturally the same to feel any type of remorse to another civilization perishing, both are unlikely
The Dark Forest has a fuckton of issues, this is one. Another is that a civilization xenophobic enough to decide to kill an entire other planet will very likely be xenophobic enough to destroy itself. You find this in all forms of phobic governments and civilizations, they never stop finding ways to otherize people who look more and more like themselves.
@@ChristianDorettiremorse is irrelevant. It's game theory. Because these weapons have a huge lag between launch and impact, they are the ultimate mutually assured destruction - a response salvo is basically guaranteed, maybe not from the victim, but others. Its likely either a sort of Galactic Geneva Convention would form, or galactic doomsday would wipe everyone out.
10:38 Although probably unrealistic, I love the idea of humanity being the only species in the galaxy that stays out of interstellar wars basically like the friend who avoids school drama.
in the Remembrance of Earth's Past series (aka the Three Body Problem) one of the weapons used to destroy entire planets is an object (the aliens called a "mass dot") fired at nearly the speed of light toward a star and hits it at the right angle to splash stellar material into the planets, burning them up. The other weapon used is the more unrealistic "dual vector foil" which turns 3d space into 2d
The three body problem also introduced interstellar deterrence. Shoot me and i return fire or give away your position to a third party. This happened when the Trisolarians broke the peace and attacked earth. Humanity detonated a cluster of nukes around a star that sent out a signal denoting the location of their attacker as well as themselves. This resulted in the aliens being killed first
My favorite part of the dual vector foil is that it doesn't affect a mass's gravity. The implication is that all the dark matter and energy we detect is just the rubble of higher dimensions collapsed into two or three dimensions.
An interesting idea from the Bobiverse series of books: If you shoot a nuclear missile at relativistic speeds, after detonation the resulting EM waves get red-shifted into even more damaging gamma radiation. It still doesn't have a planetary area of effect (for that you'd need to scale up to more warheads), but it allows a single warhead to be directional and much more fatal to all life. The advantage here is that you only need to accelerate a relatively small payload, so you don't need a skyscraper-sized missile.
The waves would not be shifted, they are the result of the collision and are not created within the dillated time of the travelling object. But if you sent an emitting body, then yes that could happen and would multiply the energy of the emitted particles
@@damianwaluszko7607 The relativistic missile is a purely physical weapon, simply having an insane momentum due to its ridiculous speed and thus a devastating impact. This idea is more like the ultra-relativistic electron beam in that the "killer" is high-energy particles that break down DNA.
This video reminds me of Cixin Liu's Three-Body Problem series. Especially at the end, where the phenomenon of launching an attack at another civilization reveals your location. This basically escalates into the situation called the 'Dark Forest', where civilizations are keeping their positions unknown, and launch species-ending attacks from remote locations at those that do due to the inability to communicate and ascertain whether they are friendly over the light-year distances. Humanity has been sending out messages to the stars for a while now.
May you please stop trying projecting fiction onto reality? Do you even took note that TBP eventually written off the DF (I.E: When Bluespace got into First Contact with a "intelligent higher a dimensional fragment"), and not to mention the "Zeroers" alongside the irony that two dimensional foil contributed to DF's collapse? Oh, and Mr Liu actually don't really agreed on his DF setting's scientific probability, and not to mention his TBP Mirror Universe Shrot Story "Ode to Joy"? Gosh, almost every single TBP fans I see are a bunch of snobs...
Not even humanity, lmao. The bacterium has changed our atmosphere to have non-natural compositions 4 billion years ago. Anyone with good enough(JWST class) telescope and basic spectral analysis knowledge would've figured out about Earth a long long time ago. Dark forest isn't real.
For that reason I do not understand why doing so much effort. A golf ball with relativistic speed to the sun seems to be sufficient due to the kinetic energy
How he would fight a interstellar war: How i would fight an interstellar war: The EMPIRE has to live! Every ship we have, HYPERSPEED! BRING THE DEATHSTSTAR! INFORM LORD VADER! WE FIGHT!
I love the subtle references to Hitchhiker’s Guide to the Galaxy. It’s one of my favorite books, and it works really well with the subject. For instance, the distance from Earth to Smorp is 42 light years - 42 is the answer to life, the universe, and everything - and they’re planning a hyperspace bypass through the solar system meaning they have to destroy the earth/humanity - probably the main conflict in Hitchhiker’s Guide.
In reality, we won't need to fear any of these unless the aliens have some form of completely new physics that allows them to hide from us for whatever reason. It's a lot harder than it sounds to hide a Dyson swarm; we can already detect fluctuating patterns in a star's luminosity with our current technology.
I feel for you, its also probably why the aliens would never use such a weapon, it would only broadcast to the entire universe where they are. the perfect civilisation killer would need to quiet and cloaked
This concept of war and sending troops being futile was actually mentioned in the Chinese sci-fi novel series “the three-boy problem” by Liu cixin. I won’t talk about the exact plot, but i will mention that the second book of the series is called “the dark forest” and is the origin of the dark forest hypothesis. Anyway, it mentions that any attempt to invade is futile because technology would have developed so much between the start and end the journey that any arriving fleet would be completely eradicated upon arrival. It also mentions how two civilisations necessarily will choose war because it is better to just kill someone than to communicate across such vast distances, not to mention that there is fundamentally no way to trust each other, since betrayal always leads to victory.
Actually it states that this attitude has already fundamentally destroyed the universe about 8 times over and is approaching the point where it will render reality permanently lifeless if it continues. The final thesis of the series is that life can only survive if it is willing to take a blind leap of faith and trust each other despite the darkness.
One of the greatest Sci-Fi novels in existence, if not THE greatest. Kind of hard to tell what it is exactly about. It is undoubtedly a sociopolitical manifesto. I read this book as a parable on determinism on every level of existence.
Now we know that the team at Kurzgesagt are actually supervillains from a different planet, and they even told us the name of their people and how they are going to destroy Earth, they did it so confidently because they already did the calcs and won
One thing that I've always figured is that if there were interstellar civilizations, space would be peaceful for the simple reason that warlikeness isn't sustainable for a nascient spacefaring civilization. In order to be warlike, you need to have enemies you can fight, which works fine if you're using pointed sticks, lead projectiles and maybe the occasional nuclear warhead as a treat, but offense outpaces defense so eventually you reach a point where warlikeness has to trail off because you either chill out, run out of enemies, or get wiped out. And war is super expensive, so a society which is kept in a warlike state needs to be exposed to a warlike foreign society close enough in tech level that they can fight back with effort in order to be made warlike. Until they get up to the point of proficient interstellar travel, a spacefaring society will have no access to anyone they could pick a fight with and stand the slightest chance of winning, because the peaceful tools of a proficient interstellar society outmatch the WMDs of a developing one. Granted, this only prevents being willing to expend serious resources towards war, so there's no guarantee that a godlike alien culture wouldn't still use weapons like these to keep competing civilizations from arising even if they wouldn't dare pick a fight with an equal.
Well in this scenario we aren’t waging war so much as trying to prevent being bulldozed by them- literally. To them we aren’t an enemy just an obstruction to their plans needed to be overcome.
and war is a tool of politics. I couldnt imagine for what reason the alien would want to wage war even for resources reason, it's just more costly to wage war than diplomacy and trade
@@Vysair Fear. The Shmorps have developed, or at least know how to develop, weapons that can sterilize a planet or star system before it could know it was under attack. Others will have as well, the physics behind such weapons are understandable well before a given civ has the tech to implement them. To be safe, Shmorps decide to strike first, destroying any civilization they detect lest those civilizations decide to do it to them first.
"even if they wouldn't dare pick a fight with an equal" why would there be any "equals"? look how much progress we make in 100 years! for 2 civilizations to be equl, they need to be within 50 years from each other in turms of progress and this will never happen
Another downside for these weapons (with possibly the exception of the missile) is the targeting. If it does take 40+ years for the laser/missile/beam to reach earth. and it goes in a straight line, it needs to be precisely targeted to where earth *will* be 40+ years later. and even a minute fraction of a degree out, and at those distances you're completely missing not just earth, but the entire solar system altogether. (the missile *may* not have this issue if it is able to adjust its trajectory while in transit)
Because of this, could a civilisation 'bump' their planet/solar system around every now and then (every decade or so) so that over the course of a year they end up in a completely different location and therefore can't be targeted by things that move at light speed (you would have to slow your weapon down so that you could find where the target is and redirect to there, and if you can see them from the weapon then they can see you and attempt a counter)
Presumably, any civilization with the means to craft and use these highly advanced weapons would also have the requisite computing power to extrapolate the position of a planet. Even with out fairly limited technology we can make some pretty good guesses with computer models. Although you'd be correct, both beam type weapons would need an incredible level of accuracy as even a micrometer off would translate to large swathes of space.
There are physical limits to precision, it's not something you can improve just by increasing computing power or energy input. At the end of the day, you still need to make your weapons from real materials that will have fundamental material properties that can't be overcome by technological prowess. Like depending on the range, the basic nature of quantum uncertainty that is fundamental to physics could make the level of accuracy completely unviable in and of itself, and that's before getting to larger problems like the fact that most materials can only get so thin (and being that thin makes them break on a dime so it's not practical here either) which limits the level of precision, not to mention the mere motion of any internals could cause enough wobble to make you miss when you're firing from so far away. @@jellef4704
@@GambitsEnd The planets orbit is not entirely predictable, there will always be variations, and they're pretty wide variations at that. We only don't talk about it much for the sake of simplicity. There would be soo many factors that they really couldn't account for it. They'd have to know all the long term orbits of everything in the solar system, and probably even the Oort cloud too, and that still wouldn't be enough, because there's still soo many other factors. They also wouldn't just be trying to target a revolving planet, but also one revolving around a moving star, so they also would have to precisely know the exact direction and speed the sun is moving, which is only something they could really do with long term observations, and even then a number of outside forces like other stars could affect that.
As someone who played spore once, it's easier to follow the religion path to dominate your planet, and use the special power you get to convert an entire planet into yours, then just save and load to override the cooldown.
Reminder: As terrifying as all that is, that is only using our current understanding of physics. In reality their weapons would be unimaginably more devastating for a ridiculously low energy/resource cost.
Yeah. Like how we used to think that the Nukes dropped in Japan was the peak of Explosion Technology, only to be proven wrong after the Tsar Bomba was invented.
@@echidnanatsuki882 No one thought that the 1940s nukes were the peak. The people who worked on the Manhattan Project were well aware of the potential of hydrogen bombs, even before a single nuke was detonated.
I imagine how in next video while explaining the countermeasures to such weaponry you'll come to conclusion that hurling an artificial Saturn in the way of attack is quite effective
I can think of one universal counter for all of them: Dodging! If a civilization has a solar motor and advance warning from quantum-entangled satellites, they can just move their system out of the way of the attack before it has the chance to land.
Pre emptivly dodging could work, just wobble your orbit as an evasive manouver as often as the two way trip of light should take to reach your enemy. It is the issue with light lag that they can never know your possition in advance. only predict your path based on previous trajectory. Of cause, they could just bypass this by shotgunning your placement with shatter shoot. But this forces their attack to be far less precice and powerful.
Big thanks for you, Kurzgesagt. 98% of the time this video is close to perfect. 99% if you are willing to add Indonesian subtitles for us loyal viewers of Kurzgesagt! ❤
"into space" is doing a lot of heavy lifting in that sentence. It's no where near far enough out there to have any chance of running into something we don't know about. How far do you think the Voyager probe is? 5 light years? 1 light year? 6 light months? It was launched over 50 years ago. It's approximately 18 light hours away. It hasn't even gotten off our porch. The entire thing about sending a message was just PR. It won't reach anything relevant until after Earth has been gone for millions of years.
One weakness that the electron beam has is magnetic shielding. If you've prepared in advance as a pre-emptive measure, you can potentially have the means to avoid being damaged. Plus, due to it being a particle beam, the line lights you and your target up like a beacon for all to see. As for the Laser, again, pre-emptive preparation is key. In addition, much like the electron beam and for the same reason, the photon beam lights you and your target up like a beacon for all to see, even if it's a system-pointer instead of a planet-pointer. The RKKVs seem to me like the most stealthy and surefire of the options. Sure, there's a blatantly obvious beacon on the missiles themselves due to the exhaust, but once they're far enough, there's no real tracing them back to you unless multiple images are taken and the difference in location is noticed, followed by a calculation of the trajectory. And on top of that, there's not really any way that I can think of to defend against it that isn't "get out of the way with an evacuation or solar motor" even with advance warning, which is pretty much a universal defense against all of the attacks.

@user-dt7px5xp6zit takes decades to get from 1 galaxy to another at the speed of light and there’s thousands of galaxies, saying there is none with absolute certainty is idiotic

Check out the short-story *The Road Not Taken* by Harry Turtledove for a twist on the classic advanced alien invader trope.
that one manhole traveling at 99.99999999999999987% the speed of light completely destroying the whole alien civilization
the manhole you're talking about was calculated to travel at around 66 km/s, which is something like 0.02% of the speed of light. and it is disputed if it actually left the Earth of if it disintegrated before leaving
You surely weren’t under the impression that manhole was near the speed of light lmfao
woosh
@melwin2251 Unfortunately, it burned up before it left Earths atmosphere. We know for sure based off of the thermodynamics of the material made and the estimated speed recorded based on the frames and they used the speed on the lower side and it was still enough to burn up before it hit space :(
How dare you ruin my dream@@MATTW3R
Imagine waiting 84 years just to hear that your intergalactic weapon hit a random planet that was in the way.
Or your math was slightly wrong and you miss
I can see the book cover: "The Most Consequential 1 in History"@@doriandavies5140
The stars are moving so you need do some serious math to predict where the planet of that star will be 42 years into the future. What if the star decreases it's speed for some reason? Even if it's a minor decrease, 42 years with that reduction and the distance in extremely far from the original one.
@@uafc1 if you can build any one of these weapons im pretty sure you have the capability to do the math
@@uafc1You can’t even calculate exactly where three point masses that are gravitational attracted in an isolated system will be in the future. You need to take it step by step, and the further out you go the more inaccurate. Imperceptible changes in the initial state will lead to a totally different outcome.
An interesting follow up video would be how a more advanced humanity might defend against such existential weapons.
Agreed, I was just thinking about that.
i was thinking ...since so many Aliens in Movies are monarchies with either a bug queen or some evil Emperor ....we may defeat them Communism ....ya know ...starting a good old french/Russian revolution and let the system destroy itself
Defenses would need to be pre emotive or in sabotaging the weapon itself. It’s not entirely feasible to intercept things moving at the speed of light as detection is impossible without ftl communications.
Unfortunately, the reality is that you can't defend yourself against attacks like these. There is no warning, and nothing you can do to stop the devastation. The only way to survive such an attack is to spread out in space, onto different planets and moons, in different stellar systems, and on artificial habitats in space. You could build a massive shield around Earth several km thick, but by that point you might as well build giant habitats in space instead. Such a shield would only reduce the damage of the electron beam, and be more of a harm than help if hit by a relativistic missile or giant laser.
@@euler4273 In this case, the best defense is the best offense. We must become Smorpian.
8:47 And yet, Steve's voice never ages. That's pure dedication
It sounds like "Nein! Nein! Nein! Nein! Nein! Nein! Nein! Nein! Nein!
If the aliens sent a message like "Surrender within 24 hours or face destruction" we could send a message back "Is that 24 hours in your time or our time?". Considering the distance involved, we could gain millions of years of extra time just by trying to sort that out.
Funny, imagine the aliens just say "....I don't like this species' tongue, activate the electron beam."
uhhh, that dont make sense really, how do they check what our reply to their demand is, whether its a yes or a no, it would still take millions of years, so it cant be 24 hours, or alternatively it sometype of rocket that gets averted or stops when we reply, in which case, assuming it has enough intelligence and human knowledge to send us the threating message, then it would also reply to our question very quickly. wtf am i doing this is probably some 13 year old, i should go back to work
That still makes no sense bc our surrender message would still take millions of years to reach, obviously this time limited threat would imply they were close to us, not millions of light years away
There’s a movie about this
As any Jujutsu Kaisen fan will tell you, "you do NOT want to get cheeky with Sukuna".

You don't know if an alien civilization is friendly, and it takes too long to find out.
Therefore, the moment you learn about it, you'd better attack first. Otherwise, there will be no time for you to fight back.

Check out the Three Body Problem series, the concepts are insane
@@manynukes11 Was just thinking the end of the video flirted with the dark forest theory.
Lesson 1: don't attack from your home base. Use another star as your attack base. If anyone retaliates, they attack right into your honeypot, revealing themselves. Welcome to interstellar war.
Interstellar assassination with rockets: You don't have to go relativistic from your home base. Use light sails at the outskirts of your home star's corona to accelerate to 0.1c and go for a somewhat nearby white dwarf (not too near). Use the flight time to assemble the rockets underway. This should be possible totally unseen and costs just a couple of years more. That's totally unimportant since nobody knows about you anyway. At the white dwarf use an Obert maneuver going relativistic. The direction of attack is changed because of the gravity of the white dwarf (that's one of the reason's for the Obert maneuver, the other is the masking of the drive's radiation), masking the true origin of the attack and since the Obert maneuver is happening very near to the surface of the white dwarf everybody thinks this is a normal astronomical event on the surface of the white dwarf. You don't have a cooling problem because of the vicinity of the white dwarf since you have the technology to cool your rocket from the immense radiation of your drive which should be very much higher than the radiation coming from the white dwarf, so that's not a problem. If necessary you could even fake a real astronomical event using your antimatter. Nothing points to your home base. If anyone figures out anything it should be clear to them that the home base couldn't be have been the white dwarf and they remain silent.

For anyone interested, the bookseries of "Trisolaris" briefly, and "The Forever War" more intensely deal with the concepts of interstellar warfare.
You mean "remembrance of Earth's past?"
@@gomshom67iscool23 You're right! Trisolaris seems to be the name for it where I'm from, but not the actual name of the series.
Charles Pellegrino's "The Killing Star" is also worth a read. Several of the ideas in the Remembrance of Earth's Past series came from that novel.
Alternatively, the Dune series... if you want the really weird, perverted answer. The answer is not in "the Spice." It's in the theoretical "Golden Path" which is essentially "spread far across the universe, mutate, evolve, and get so weird that even humanity as it exists can't predict what you might do."
I want to do a skibid toilet episode
Honestly, the UREB is probably the most terrifying concept this channel has ever discussed. A ghostly interstellar cancer laser that spares most inorganic resources. It also almost requires the weapon to be a good distance from the user's homeworld. So seeing where the beam is coming from only gives you a rough estimate of the user's home location. Such a dreadfully compelling weapon. I guess the one drawback compared to the other options is that it would take a hot minute to aim. But when your shot takes decades to reach target, I think taking a week to line up said shot can be forgiven.
and also its the most expensive weapon to make out of the 3 considering the sheer size of the weapon

There is a great Polish novel called "The Oldness of the Axolotl". The Earth was suddenly attacked by something similar to weapon number 3. Few thousand of peoples managed to survive by transfering their minds to electronic media (only half of the planet was destroyed in the first second, so some had up to 12 hours to prepare). The story takes place over hundreds of years and presents attempts to rebuild civilization and life while the main character slowly descends into madness.

Aww yis! I love his books, but didn't read this one
@@fansyuriilham8557 I thought the idea sounded familiar! You're right though, Into the Night was.. not great.
There’s also a somewhat similar weapon utilized by what are referred to as “The Others” in _The Bobiverse_ series. Although, I don’t think it uses electrons, just gamma radiation and it’s not as long range.
An ''invasion'' or ''war'' probably only works if the two civilizations have roughly the same kind of technology. In all other cases, one will simply take over or destroy the other before they are aware of it.
My thought exactly. The idea of aliens destroying us is potentially possible but not realistic because they would have already done it if they had the weapons for it.
A minimum 42-year travel time almost definitely means the invaders will have outdated technology upon arrival.
Two civilizations could have vastly disparate technology and the less advanced one could still kill the more advanced. They just have to by chance discover the advanced one first (or the more advanced one decides to ignore them) and be just technologically capable enough to build a weapon that takes out the other side in one shot.
@@wasd____ Good suggestion! In fact it reminds me of a series of science fiction novels written by Harry Turtledove. Central point: During WW2 an alien colony/invasion fleet arrives on Earth.

The book "The Forever War" by Joe Haldeman is an allegory for the Vietnam War but set in the distant future. The theme of "future shock" is a big part of the story. Humanity encounters an alien species who are basically in the "Old West" phase of weaponry and wipe the floor with them. A few hundred years later, relativistically only a couple years for the protagonist, the alien race has advanced way beyond humanity's capabilities and humans resort to a trench style warfare where they shelter under an energy shield and fight hand to hand.

One thing not mentioned (but possibly implied) is that you cannot aim directly at the planet. All heavenly bodies are zooming through space, not stationary. Instead you would have to calculate the target's location at the expected time of impact and aim for that. It's extremely unlikely, but you would also have to ensure no planets/stars move into the path of the weapon before impact.
You only have to account for relative moment of the target planet in it's orbit. Since both solar systems are essentially neighbours in the same galaxy, all other motion (aka, rotation of the galaxy, traversal of the galaxy through space, etc) would be identical, and therefore not affect the projectiles trajectory (even if it's a beam without physical matter).
Though now that makes me wonder whether that 'mutual lateral movement' might end up messing with the estimated % of lightspeed... because for every x km/s you are travelling sideways in parallel to your target, you have y km/s less maximum velocity towards your target, since the vector of your total movement cannot exceed c. Or can it, because you're still travelling at
its true that its hard to aim but you have literally "infinite ammo" and can shoot over a large area for a long time and rotate your laser on a grand-sacle. Maybe 1 Month of moving the mirrors arround. You will definetly make a hit.
@@Alblaka The mutual lateral movement does not mess with the speed, it's to be completely out of the equation, the only thing that matters is the relative velocity between the two bodies, if both are travelling at the same speed through space, that's not an issue
Keep in mind that the speed of light is a measure in which the units are meters per seconds, which is space divided by time, both of which are relative to our frame of reference already, so while the light will always appear to be going away or towards you at the same rate in any frame of reference, distance and time are relative to the motion between the two observers
this is true, but a much easier option is to fire a weapon at the star instead. For example, a missile going at the speed of light striking into the Sun would likely cause a devastating solar flare or radiation emission that could destroy Earth. It is much easier to detect the location and movement of a star
Or you just calibrate the weapon to be drawn to the gravitational pull of the planet as a “compass”

You guys should do a video on interplanetary warfare; like if there turned out to be an underground civilization on Mars all along, or if a fleet of Venusians emerged from the clouds. The distances are still vast, sure, but not as vast as interstellar space, so there'd be room for more "standard" weapons (kinetic strikes, EMPs, invasion fleets, etc.).

Read The Expanse series if you haven't! It's mostly what you describe!. Also Red Rising, but it's more soft sci fi for sure.
We've sent vehicles to Mars, I imagine just modifying them to dispense nukes would be effective enough. And simple!
Or more likely, if, in 500 years, the human population on Mars goes to war with humanity on Earth.

The “hyperspace bi-pass” 😂😂😂😂 for anyone that doesn’t know the movie. * Hitch hikers guild to the galaxy, is a must watch comedy sci-fi.
The math on the star laser and electron beam would have to be insanely accurate, because you need to shoot it exactly where the Earth will be in the galaxy when it arrives, not to mention however the laser will bend if it goes near any intense spacetime curvature like black holes and neutron stars. Even the smallest bit off course, especially in the the first half of its trip, and it’ll totally miss us by the time it arrives. I’m not sure it’s actually feasible, even for an advanced civilization. The relativistic rocket, which could constantly be recalculating and making extremely slight adjustments, would probably be the only way to have a chance at hitting the target.
exactly! i immediately thought of how it would be impossible to pull-off that laser thingy
Also, missing with a weapon like that broadcasts your position to anything and everything capable of detecting planet-killer weapons.
And none of these are weapons that get you left alone.
As he said at the end; that if we see interstellar warfare we better stay out of it. This is most likely the scenario for other alien species too so it's probably a very slim chance others would intervene or try to be on the safe side by attacking the attacker, they themselves could in turn become a target aswell.
It gets even better for relativistic kinetic kill missiles: even if you were able to detect them before they hit and destroyed them before they reach your planet...you'll have potentially thousands, if not millions of near-light speed debris pummelling you in a shotgun blast pattern.
@@nil981If their technology is operating within so called interstellar space, I assure you that they would most definitely have a force repulsion capability
With how big the universe is, the aliens would really need to go out of their way to do something like this.
In a universe of millions of intergalactic civilizations it only takes a small fraction of them to be genocidal to be kind of a problem, so I guess it depends on how many are out there.
That is kind of the point of the video, actually. I mean, imagine the entire electrical grid of the US being used for 24 hours to power a laser aimed at Russia, with 24 hours of planned blackouts across the country to power it. It's only one day of disruption, but it's one day of a LOT of disruption.
Now multiply that by a million. And also, in order to USE that energy, you have to build something practically the size of jupiter.
Yeah, they're going out of their way to do it. Fair estimate. Considering how much wild excess the US currently puts into its military spending, though... Is it really that unbelievable to imagine a larger civilization using a proportionately similar amount of resources?
@@SubtleHawkNot really. If the universe was made up of millions of civilizations and only a fraction of them were genocidal then the hundred or so non genocidal ones nearby to singular genocidal one would likely keep them in check some how.
Unless the genocidal one was leagues ahead in technology but if that was the case then none of the others would be around them.
If they were genocidal they likely wouldn't even bother to invade. Just one day earth would be hit by a relativistic weapon and it would be over for us.
They wouldn't even have to know we were here. They could have just detected signs of life from when the dinosaurs were around and launched their weapons millions of years ago.
Course if it was relativistic it would likely have been reached sooner but that still means they could detect and kill earth at any point in the distant past.
The fact that earth is still around is a good sign that there are no genocidal aliens anywhere remotely close by.
The universe could actually be really small to something we don't know about. Things like physics and distance could also be completely arbitrary values that can change on a whim. We might wake up one day and find that interstellar travel is suddenly easy and never know why things changed.
I mean we pave through forest to build highways when we could go around
Liu Cixin has a great book/audiobook series about this, I highly reccomendations it. Spoilers: a major theme of the books is the "dark forest" concept, where all you have to do is broadcast the coordinates of a star out into space, and it will be destroyed. This is because his solution to the fermi paradox: as soon as life in the universe reveals itself, the most powerful and reclusive aliens will destroy it as soon as possible in order to survive. Since there is always going to be a social and technological barrier between any 2 alien worlds, the only way a species can thrive is to eliminate any other form of life before it surpasses them in technology. Perfectly transparent communication of intention is always impossible, so each species must assume the worst and take steps to eradicate each other.
Like another comment said, the ultimate moral is that each party must take a leap of faith (against all logic and reason) to trust each other. Otherwise the universe continues to be an endless arms race untill its complete and total collapse.
So it's like interstellar "SWATting".
yeah, read that too.

The funky thing about interstellar warfare is that if you want to eradicate all life and plan to send troops, you have to accelerate and then decelerate large vessels to near relativistic speeds
Not sending any troops means you can send a way smaller object and there is no need to decelerate at all.
To be fair, the same holds true on earth as well.
A missile attack is certainly landing faster in location X than any type of troop transporter.
Granted regular communication is much easier here on earth, aka the conflict might be avoided.
@@peterpan4038the similarities break when you consider that troop transport is not using rocket engines
Nobody is going to bother bringing troops over to invade. There is nothing precious enough on larger planetary bodies, you won't find easier accessible in asteroids or moons.
Not to mention how troops have to be kept alive and stuff meaning the stuff you send has to be bigger, air tight, have radiation shielding, etc.
What if you are just a really advanced civilization that can traverse space-time with the ability to accurately model evolution over a couple million years and you send a biological weapon in the form of a single cell filled asteroid to destroy the native life and spawn a creature that invades and spreads across the entire planet while destroying the habitat and atmosphere with poisonous gas and radiation?

Sad news for the Smorpians: During the time that you see, that’s its position 42 years ago; and when you shoot, the Sun, along with Earth and other planets would have moved by ≈291.3 billion km, and when you fire the missile, it would need to travel for another 42 years, so when you missile reach, the solar system would have moved by another ≈291.3 billion km, so you’ll be off ≈582.7 billion km from the target. Even if you somehow manage to aim at Earth, there could be celestial bodies in the way, so it could block, reflect, distort, bend, … the trajetory. Even if there aren’t any objects in the way, if an object has a magnetic field, it could deflect the paths of the electrons. Even if you manages to hit Earth with electrons, the magnetic field would deflect them
Using that, interstellar war is not easy because stars, planets, asteroids, comets, and even black holes are moving. Because of that, a star system would have moved enough to dogde any of those weapons. Even if it doesn’t miss, celestial bodies that are moving could reflect, block, distort, refract, bend, … the weapon’s trajectory. Even if there aren’t anything in the way, if an object has a magnetic field, it could deflect the charged particles, even if the aren’t anything or magnetic fields, if the planet/star/moon has one, it would deflect them. So yeah, i think we, along with other aliens (if existed) will never get hit by any of those weapons

Love how you's went full "3 Body Problem" in this video 👌🏽
This video accurately describes one of the reasons why the Dark Forest theory is extremely unlikely to be correct. If any one galactic civilization attacks another with a superweapon such as this, they will pretty rapidly get dogpiled by all the others. It is in everyone's best interest to play relatively nice with others.
Unless they do it to everyone else first; nobody would know, all adversaries would be extinct as soon as they are identified,before they can react and before they can issue any warning to anyone else (and, even then, these others would have been targeted already anyways).
In theory, an extremely aggressive belligerent alien civilization could be sterilising any planet with anything living or intelligent enough as soon as they detect them... And by the time anyone else is aware they'd be gone or targetted beyond reaction time already
Only for that to happen they will have to be aware of each other, they will have to be culturally the same to feel any type of remorse to another civilization perishing, both are unlikely
It's like trying to shoot a deer in the forest and getting surrounded on all sides by the military
The Dark Forest has a fuckton of issues, this is one. Another is that a civilization xenophobic enough to decide to kill an entire other planet will very likely be xenophobic enough to destroy itself. You find this in all forms of phobic governments and civilizations, they never stop finding ways to otherize people who look more and more like themselves.
@@ChristianDorettiremorse is irrelevant. It's game theory. Because these weapons have a huge lag between launch and impact, they are the ultimate mutually assured destruction - a response salvo is basically guaranteed, maybe not from the victim, but others. Its likely either a sort of Galactic Geneva Convention would form, or galactic doomsday would wipe everyone out.
10:38 Although probably unrealistic, I love the idea of humanity being the only species in the galaxy that stays out of interstellar wars

in the Remembrance of Earth's Past series (aka the Three Body Problem) one of the weapons used to destroy entire planets is an object (the aliens called a "mass dot") fired at nearly the speed of light toward a star and hits it at the right angle to splash stellar material into the planets, burning them up. The other weapon used is the more unrealistic "dual vector foil" which turns 3d space into 2d
Don't forget the ultimate weapon of mass destruction
SPOILERS:
Doxxing your enemies with your star
The three body problem also introduced interstellar deterrence. Shoot me and i return fire or give away your position to a third party. This happened when the Trisolarians broke the peace and attacked earth. Humanity detonated a cluster of nukes around a star that sent out a signal denoting the location of their attacker as well as themselves. This resulted in the aliens being killed first
The Drop was the ultimate weapon. Using the most primitive method - ramming, it obliterated every defense system
Was scrolling through for this comment. The Droplet and the 2D weapon are just incomprehensible
My favorite part of the dual vector foil is that it doesn't affect a mass's gravity. The implication is that all the dark matter and energy we detect is just the rubble of higher dimensions collapsed into two or three dimensions.

Nahhhh
An interesting idea from the Bobiverse series of books: If you shoot a nuclear missile at relativistic speeds, after detonation the resulting EM waves get red-shifted into even more damaging gamma radiation. It still doesn't have a planetary area of effect (for that you'd need to scale up to more warheads), but it allows a single warhead to be directional and much more fatal to all life. The advantage here is that you only need to accelerate a relatively small payload, so you don't need a skyscraper-sized missile.
The waves would not be shifted, they are the result of the collision and are not created within the dillated time of the travelling object. But if you sent an emitting body, then yes that could happen and would multiply the energy of the emitted particles
@@LeAdri1du40 There would be no collision. The missile detonates before reaching its target.
Maybe I missed something but in the video we also have small payload, just 300kg. Rest is huge fuel tank so our missile get enough speed
@@damianwaluszko7607 The relativistic missile is a purely physical weapon, simply having an insane momentum due to its ridiculous speed and thus a devastating impact. This idea is more like the ultra-relativistic electron beam in that the "killer" is high-energy particles that break down DNA.
You mean blue-shifted?
This video reminds me of Cixin Liu's Three-Body Problem series. Especially at the end, where the phenomenon of launching an attack at another civilization reveals your location.
This basically escalates into the situation called the 'Dark Forest', where civilizations are keeping their positions unknown, and launch species-ending attacks from remote locations at those that do due to the inability to communicate and ascertain whether they are friendly over the light-year distances.
Humanity has been sending out messages to the stars for a while now.
kurzgezagt actually made a video on that exact phenomenon

May you please stop trying projecting fiction onto reality?
Do you even took note that TBP eventually written off the DF (I.E: When Bluespace got into First Contact with a "intelligent higher a dimensional fragment"), and not to mention the "Zeroers" alongside the irony that two dimensional foil contributed to DF's collapse?

For instance, the distance from Earth to Smorp is 42 light years - 42 is the answer to life, the universe, and everything - and they’re planning a hyperspace bypass through the solar system meaning they have to destroy the earth/humanity - probably the main conflict in Hitchhiker’s Guide.

In reality, we won't need to fear any of these unless the aliens have some form of completely new physics that allows them to hide from us for whatever reason.

@@cupur Read the third book in the series, "Death's end", you will know how quiet an interstellar weapon can be.
This concept of war and sending troops being futile was actually mentioned in the Chinese sci-fi novel series “the three-boy problem” by Liu cixin. I won’t talk about the exact plot, but i will mention that the second book of the series is called “the dark forest” and is the origin of the dark forest hypothesis. Anyway, it mentions that any attempt to invade is futile because technology would have developed so much between the start and end the journey that any arriving fleet would be completely eradicated upon arrival. It also mentions how two civilisations necessarily will choose war because it is better to just kill someone than to communicate across such vast distances, not to mention that there is fundamentally no way to trust each other, since betrayal always leads to victory.
Actually it states that this attitude has already fundamentally destroyed the universe about 8 times over and is approaching the point where it will render reality permanently lifeless if it continues.
The final thesis of the series is that life can only survive if it is willing to take a blind leap of faith and trust each other despite the darkness.
It vaguely reminds me of Joe Haldeman's "The Forever War".
"the three-BOY problem" hmmmmmmmmmmmmmmmmmm. ( ͡° ͜ʖ ͡°)
One of the greatest Sci-Fi novels in existence, if not THE greatest. Kind of hard to tell what it is exactly about. It is undoubtedly a sociopolitical manifesto. I read this book as a parable on determinism on every level of existence.
All the video reminded me of the trilogy. Not a bad thing, tho.
Now we know that the team at Kurzgesagt are actually supervillains from a different planet, and they even told us the name of their people and how they are going to destroy Earth, they did it so confidently because they already did the calcs and won
real
You didn't already know that? I thought it was obvious that they're agents of an evil interstellar overlord! Have you ever MET a duck?
I love them, they ask the silly questions but give genuine answers
One thing that I've always figured is that if there were interstellar civilizations, space would be peaceful for the simple reason that warlikeness isn't sustainable for a nascient spacefaring civilization. In order to be warlike, you need to have enemies you can fight, which works fine if you're using pointed sticks, lead projectiles and maybe the occasional nuclear warhead as a treat, but offense outpaces defense so eventually you reach a point where warlikeness has to trail off because you either chill out, run out of enemies, or get wiped out. And war is super expensive, so a society which is kept in a warlike state needs to be exposed to a warlike foreign society close enough in tech level that they can fight back with effort in order to be made warlike. Until they get up to the point of proficient interstellar travel, a spacefaring society will have no access to anyone they could pick a fight with and stand the slightest chance of winning, because the peaceful tools of a proficient interstellar society outmatch the WMDs of a developing one.
Granted, this only prevents being willing to expend serious resources towards war, so there's no guarantee that a godlike alien culture wouldn't still use weapons like these to keep competing civilizations from arising even if they wouldn't dare pick a fight with an equal.
Well in this scenario we aren’t waging war so much as trying to prevent being bulldozed by them- literally. To them we aren’t an enemy just an obstruction to their plans needed to be overcome.
and war is a tool of politics. I couldnt imagine for what reason the alien would want to wage war even for resources reason, it's just more costly to wage war than diplomacy and trade
@@Vysair Fear. The Shmorps have developed, or at least know how to develop, weapons that can sterilize a planet or star system before it could know it was under attack. Others will have as well, the physics behind such weapons are understandable well before a given civ has the tech to implement them. To be safe, Shmorps decide to strike first, destroying any civilization they detect lest those civilizations decide to do it to them first.
Not sure why it'd be expensive if you have unlimited energy
"even if they wouldn't dare pick a fight with an equal" why would there be any "equals"? look how much progress we make in 100 years! for 2 civilizations to be equl, they need to be within 50 years from each other in turms of progress and this will never happen
I have the feeling that the kurzgesagt Team is Isaac Arthur‘s greatest fan.
Another downside for these weapons (with possibly the exception of the missile) is the targeting. If it does take 40+ years for the laser/missile/beam to reach earth. and it goes in a straight line, it needs to be precisely targeted to where earth *will* be 40+ years later. and even a minute fraction of a degree out, and at those distances you're completely missing not just earth, but the entire solar system altogether. (the missile *may* not have this issue if it is able to adjust its trajectory while in transit)
Very important to pull a serpentine manoeuvre with your shkadov thruster
Because of this, could a civilisation 'bump' their planet/solar system around every now and then (every decade or so) so that over the course of a year they end up in a completely different location and therefore can't be targeted by things that move at light speed (you would have to slow your weapon down so that you could find where the target is and redirect to there, and if you can see them from the weapon then they can see you and attempt a counter)
Presumably, any civilization with the means to craft and use these highly advanced weapons would also have the requisite computing power to extrapolate the position of a planet. Even with out fairly limited technology we can make some pretty good guesses with computer models. Although you'd be correct, both beam type weapons would need an incredible level of accuracy as even a micrometer off would translate to large swathes of space.
There are physical limits to precision, it's not something you can improve just by increasing computing power or energy input. At the end of the day, you still need to make your weapons from real materials that will have fundamental material properties that can't be overcome by technological prowess. Like depending on the range, the basic nature of quantum uncertainty that is fundamental to physics could make the level of accuracy completely unviable in and of itself, and that's before getting to larger problems like the fact that most materials can only get so thin (and being that thin makes them break on a dime so it's not practical here either) which limits the level of precision, not to mention the mere motion of any internals could cause enough wobble to make you miss when you're firing from so far away. @@jellef4704
@@GambitsEnd The planets orbit is not entirely predictable, there will always be variations, and they're pretty wide variations at that. We only don't talk about it much for the sake of simplicity. There would be soo many factors that they really couldn't account for it. They'd have to know all the long term orbits of everything in the solar system, and probably even the Oort cloud too, and that still wouldn't be enough, because there's still soo many other factors. They also wouldn't just be trying to target a revolving planet, but also one revolving around a moving star, so they also would have to precisely know the exact direction and speed the sun is moving, which is only something they could really do with long term observations, and even then a number of outside forces like other stars could affect that.
As someone who played spore once, it's easier to follow the religion path to dominate your planet, and use the special power you get to convert an entire planet into yours, then just save and load to override the cooldown.
Imagine a species like the grox using these types of weapons to sterelise the galaxy
Doesn't this violate intergalactic law? I find it easier to de-terraform, then capture a T-1 planet with like 2-3 cities, then terraform again
John 14:6 NLT - Jesus told him, “I am the way, the truth, and the life. No one can come to the Father except through me.
@@RammusTheArmordillo Intergalatic law doesnn't matter when you can destroy anyone who wants to enforce it within seconds.
As someone who likes to play games where I either explore space objects or colonize them, thanks for your help!
Can you tell me such a game they sound fun ! Please share

@@fodk7021yeah what the other guy said
@@aritzgames6991 You mean Galactic Genocide Simulator?
0:59 You literally just made a Hitchhiker's Gide To The Galaxy reference😂
As a allactician, I can confirm that you helped us find the smorpians' plans
Reminder: As terrifying as all that is, that is only using our current understanding of physics. In reality their weapons would be unimaginably more devastating for a ridiculously low energy/resource cost.
All of this is just assuming they don't just choose the truly efficient option of simply waiting a few decades. Much, much less work.
Yeah.
Like how we used to think that the Nukes dropped in Japan was the peak of Explosion Technology, only to be proven wrong after the Tsar Bomba was invented.
@@echidnanatsuki882 No one thought that the 1940s nukes were the peak. The people who worked on the Manhattan Project were well aware of the potential of hydrogen bombs, even before a single nuke was detonated.
@@echidnanatsuki882 literally no one thought that
Indeed. Put wormholes into the mix and you could have instant weapons.
I imagine how in next video while explaining the countermeasures to such weaponry you'll come to conclusion that hurling an artificial Saturn in the way of attack is quite effective
I can think of one universal counter for all of them: Dodging! If a civilization has a solar motor and advance warning from quantum-entangled satellites, they can just move their system out of the way of the attack before it has the chance to land.
@@kennyholmes5196 information can’t travel faster than light, that’s not how quantum entanglement works
The only warning would be from seeing the Smorpians building the thing through a telescope. Or spies sending you a message.
Pre emptivly dodging could work, just wobble your orbit as an evasive manouver as often as the two way trip of light should take to reach your enemy. It is the issue with light lag that they can never know your possition in advance. only predict your path based on previous trajectory. Of cause, they could just bypass this by shotgunning your placement with shatter shoot. But this forces their attack to be far less precice and powerful.
@@smth_smth_idk_xd Actually, it is. The change for a quantum-entangled particle is instantaneous.
Big thanks for you, Kurzgesagt. 98% of the time this video is close to perfect. 99% if you are willing to add Indonesian subtitles for us loyal viewers of Kurzgesagt! ❤
Kurzgesagt: "Better stay relatively quiet"
Meanwhile NASA: send naked human picture into space
"into space" is doing a lot of heavy lifting in that sentence. It's no where near far enough out there to have any chance of running into something we don't know about.
How far do you think the Voyager probe is? 5 light years? 1 light year? 6 light months? It was launched over 50 years ago. It's approximately 18 light hours away. It hasn't even gotten off our porch. The entire thing about sending a message was just PR. It won't reach anything relevant until after Earth has been gone for millions of years.
Alien gooners: 👁🐽👁
One weakness that the electron beam has is magnetic shielding. If you've prepared in advance as a pre-emptive measure, you can potentially have the means to avoid being damaged. Plus, due to it being a particle beam, the line lights you and your target up like a beacon for all to see.
As for the Laser, again, pre-emptive preparation is key. In addition, much like the electron beam and for the same reason, the photon beam lights you and your target up like a beacon for all to see, even if it's a system-pointer instead of a planet-pointer.
The RKKVs seem to me like the most stealthy and surefire of the options. Sure, there's a blatantly obvious beacon on the missiles themselves due to the exhaust, but once they're far enough, there's no real tracing them back to you unless multiple images are taken and the difference in location is noticed, followed by a calculation of the trajectory. And on top of that, there's not really any way that I can think of to defend against it that isn't "get out of the way with an evacuation or solar motor" even with advance warning, which is pretty much a universal defense against all of the attacks.
I love that I've grown up to Steve Taylor. He has such a calming, yet captivating voice!
