Space Invaders taught me that I should not shoot where they are, but WHERE they WILL BE! Seems Atari had the light lag issue figured out nearly 40 years ago!
Did you ever play quake in the 1990s? The fastest internet speed was 56K but most people got 28.8K. This meant pings of over 1 second. As a result everybody had to learn to lag shoot or use area of effect weapons like the rocket launcher.
Same strategy with Atari Asteroids. Those of us who learned these games in the late 70s and 80s will clearly have a head start in any future interplanetary war. This benefit will possibly be annulled by the fact we'll be too decrepit to be of much help. Hey ho.

As i heard somewhere, accelerate a 20 kilogram slug to 1,3 percent of the speed of light you got a 35 kiloton yelded weapon of mass destruction.. Great video
ander azakuna+ E=mc^2-m[0]c^2 and m= (m[0]) / ( squareroot( 1 - ( (v^2) / (c^2) ) ) so E = ( (m[0]) / ( squareroot( 1 - ( (v^2) / (c^2) ) ) ) * c^2 - m[0] * c^2 So E = ( (20kg) / ( squareroot( 1 - ( (0.013^2) / (1^2) ) ) ) * c^2 - 20kg * c^2 = 1.5 * 10^14J = 150 TJ And tnt-tonnes are 4.184 GJ so 150 TJ is 36000 tonnes of tnt or 36 kilotons so it is actually bit more than that.

I'd assume a capital ship could send out hundreds of these slugs per minute. Not sure how thick the armour needs to be just take damage from just a fraction of that potential 3.6 megaton per minute.
+abz998 Not necessarily, for an example lets say that we have a 250,000 ton ship ie around the mass of 2.5 Gerald R Ford class supercarriers that means that the ship has a mass some 12,500,000 times the mass of the slug thus each slug it fires the recoil will accelerate the ship by 1/12,500,000th the velocity of the slug. 1.3% of light speed is about 3,900 km/s so the delta-V on the ship per slug fired would be equivalent to 0.312 m/s. That equates to an acceleration of 1g for every 31.44 rounds per second of fire rate, at just 314.42 rounds per second the acceleration would be 10g's if that ship has a human crew they could only fire their guns for a minute a most without killing their crew. Granted it would have fired a total of 376 metric tons of ammunition by then though that need not necessarily exhaust the magazine of a 250,000 ton ship it's only 0.15% of the mass of the ship after all.
Honestly, all it would take is one crazy Elon Musk style scientist and that could be the scientific term for giant space guns once they do exist. Scientists are certainly a lot better than historians when it comes to naming stuff, at least.
Passiee on the other hand, it may end up with a name like IPC-171A3 "Long Tom" if it's American, and some horribly complicated series of letters and numbers if it's built by the UK.
It'd be simple and annoying to the opponent to just litter their orbit with our space trash while they are on the other side of the sun. Kessler Syndrome might disable their ability to launch weapons against us!
Actually that's not a bad first strike, if you want to initiate hostilities, hijack a big cargo ship of ice or something for mars then detonate the thing in orbit, and launch all your missiles just before that so the light arrives at the same time. Screw up their defenses pretty good, cause a big distraction, and probably conceal the launch.
I remember when there was less than a thousand subs when I subbed. You know for a fact the channel has grown not only when you see the almost 140k subs but the first comments you see on popular channels videos. It's beautiful to of seen Issac come so far. Love you man and keep the great work your videos are amazing and have a HAPPY Issac arthursday 😊
Yeah we've been growing like a weed, we're technically coming up on the 3rd anniversary next month but I always think of the channel really starting in spring 2016, back when there was maybe 1500 subs tops.
It doesn't seem that long since you hit 100k. You're at 139k already. I'm not at all surprised, you're an excellent science communicator and you pick really interesting thought provoking topics. Me and my friends joke that you upload 'hour and a half' 30 minute videos, because we always end up pausing and sitting in a near catatonic state for ages thinking about and discussing all the possibilities you bring up.
lolmao500 When I tried your link it didn't work, is this the same story? www.sciencealert.com/a-new-twist-on-fusion-power-could-create-limitless-clean-energy
lolmao500 I've just had a read, and no, it's not. The story I've now found has exactly the same address as the one you gave, so it's weird that it didn't work directly.
The danger I see is in leaders underestimating their opponents in the 'first' interplanetary war, and being wiped out, but not before doing significant damage to any shared megastructures we have constructed by then. Just like how the nuclear defense developments (SDI and fallout shelters) made people feel more like using nukes, not less. Amazing video as always!
Can't wait for the "Uplifting" episode, I'm a big David Brin fan and I know Isaac Arthur will give this topic the in depth analysis of why, when, what and hows Uplifting deserves.
Such a daunting editing challenge simply touching on What to uplift, squids to help humans collect Manganese nodules as opposed to Honey Badgers for God only knows reasons, can take up a hour in itself. :)
"Which also means you've got a lot more money to spend on giant space guns." I just love your sense of humor, so thanks for being the audio I put on as I lay down to sleep.
The best example of this concept I've seen was actually in Zone of The Enders and ZOE2. A government of Earth asserting mastery over Mars, Mars rebelling, rebellion spreading, and long times pass between major battles. Thoroughly entertaining, to me, at least.
The game Interplanetary takes this concept and runs with it, you can use artillery, missiles, lasers, but its all on your planet, you have to beat the other guys, if you think this kind of warfare is interesting, than I suggest give it a try.
Also, the non-laser weapons all travel on ballistic trajectories, meaning you have to aim them. This can be exhilarating when you pull off an incredible shot or hilarious when someone accidentally shoots their own planet, but it implies a shockingly poor orbital point defense system for planets devoting basically their entire economies to warfare. ...Then again, they're weirdly reluctant to put ANYTHING in space. Mines, power satellites, weapons? Nope, outside the occasional special project that still includes a ground component you can shoot at.
Rule # 1 of warfare = every single thing ever, always. I am a shipmate, a futurist and a techno optimist. I am also spiritual and cant help but be terrified of total war. I have been listening to your talks on my walk to work every day and i cant help but feel completely inspired by you. good work boss. you are a very interesting person and what you have to say correlates .
I've never been this excited to see a notification pop up on my phone. I've thought about this topic for a long time as I've always wondered what actual warfare in space would be like due to the vast time and distance differences.
Your analogies are not only brilliant and spot-on, they generally keep me in good spirits all Arthursday long!! Thank you for another way awesome episode.
It's fascinating, imagine continent-size ships that just roleplay a fantasy world. And people can opt to forget who they are and live simple lives. Or a ship that's full of entertainment like malls, arcades, clubs, etc. Everyone living how they like, even the animals that have their dedicated ships. All your videos, really inspire sci-fi and what makes it more exciting is that we know that it is possible within the realm of physics and not some fantasy that is impossible. Inspiring the future to follow suit.
Good thing Thursday was decided on. Can you imagine what a mouth full it would be if he uploaded on Wednesday? "Happy Arthwednesday!" Goodness, what a nightmare. Though I guess Saturday would've been okay too... Isaaturday?
Im currently making a scifi tabletop game for my friends, and stumbled upon your channel. This is basically a treasure trove of inspiration and ways to actually ground everything in. Thanks for what you're doing, keep up the good work with these videos. Im definitely gonna be sticking around.
Isaac the gunner in da house! Very nice episode. Very cool, keeping it hard sci-fi. All sorts of awesomeness here. I think this is one of those super thick episodes which needs, nay demands multiple viewings.
I believe that in Halo:The Cole Protocol that to dodge the covenant weapons they had explosive vents which I imagine we could put small pockets that explodes with enough force to move the missile to the side
The empire is the most feared in all the Galaxy. The sound of pew pew pew shakes the hardest of veterans with the worry of property damage done. Thankfully no one have ever been shot on purpose.
If orbital lasers and missiles are the only means of planetary defense, then the ultimate counter to them would be building kamikaze droneships with a reflective mirror heatshield in front, to absorb/deflect lasers, and laser cannons of its own, to destroy any projectile-based weapon fired at it. With such defenses, the ship would be able to get close enough to the enemy planet in order to either ram it directly at relativistic speed or detonate a nuke inside its atmosphere. Such a ship would also have room for thrusters with which to evade ships or fighters sent to ram into it. These small ships could be launched either from your planet directly or from a supercarrier capital ship.

Hey! Your megastructures-ringworlds episode is coming out on my 17th birthday! Thanks in advance for the probably awesome (who am I kidding, DEFINITELY awesome) birthday gift!
People may not become more peaceful over time for any moral or philosophical reasons. But as society becomes more wealthy *and* that wealth is spread more evenly among the population, the root cause of war - greed - would lose force. If society becomes as widespread and wealthy as shown in videos like this one, war would become as undesired (and hopefully as rare) as widespread famine or pestilence. That may be an over-simplification of course, but I'd like to think it is at least basically correct.
Quite so; just look at ISIS. But by and large I agree with your original point. These days religions are just as divisive as politics are... but maybe someday we can solve those problems just as science and technology have solved so many others (though admittedly they've created a few too; I think we're all happier with them than we would be without them)
Jason Toddman depends on the fragility of your society. If war is mostly a function of both states throwing disposable income and robots around as long as it is balanced, it might be very common indeed. If brutal conquest is the consequence for losing, but the only consequence for fighting is a tax on people who already make more than enough to provide for themselves, that makes the first rule of war "don't lose."
If the cost to your society is the equivalent of "you can only buy a new cellphone, laptop, and nice car every year instead of every 11 months," and all your cost is coming out of imaginary appetites anyway, I could well see a society putting a lot of its GDP toward weaponry and being more than willing to nuke enemy robots using their own robots at even minor provocations. The Soviet union largely lacked severe poverty for most of its existence, but had little issue chucking away massive amounts of resources on war machines. America has been wealthy since its inception, again with absolute poverty being a rare occurrence, and it spends more on war machines than the rest of the world combined. If your people live under fully-automated luxury communism or a classically liberal automated capitalist juggernaut where the poorest in your society are working 15 hours per week to live a lifestyle equivalent to the upper middle class of today, spending a considerable portion of your expenses on death-less warfare may seem attractive, especially if you think you can get better deals with the threat of actual violent warfare.
Jason Toddman in fact, I would go so far as to say that in the past, abundance has brought a lust to test one's new capabilities of destruction, not an era of peace.
Like, it's a bit of a weird example, but when I've been in Minecraft factions, where luxury confederal communism tends to be the default mode of societal production and distribution, there are a few distinct phases. Usually warfare occurs early on, when a decent lifestyle is hard to earn, and in late-game skirmishing, where idle hands start going into automated warfare without much expense to quality of life, with occasional large-scale successful raids sending someone a few levels of development back. I feel a lot more willing to throw nukes around when they are being auto-assembled by robots from raw ore. Further still, I've discovered that the things necessary for industrial-scale warfare are also necessary for industrial-scale civilization. You do not go hunt a thousand creepers to annihilate the enemy military complex or carve out million-block areas. You build skyscraper-sized mobgrinders that produce more TNT and arrows than you know what to do with. You don't painstakingly hollow out the nether from bedrock to bedrock to limit enemy activities. You again get the industrial base to do such things first, not because you want war, but because that is simply the cheapest way to churn out millions of blocks of raw material for building more stuff. Having no real human cost to starting wars would, one should presume, make doing so more likely, not less. When it's our drones vs. Theirs and nobody starves either way, war is pretty attractive.
This episode, and a previous one I watched, reminds me of two space combats from two difference authors. Kim Stanley Robinson, and Ian Douglas (William Keith Jr.). In Robinson's 2312 there was an attack on a solar shield. It was planned with a point defense system in mind. Several small pea sized pebbles were fired at various places around the solar system to converge on a point on the sun shield. In one of Ian Douglas' military sci fi series he had a human fleet sand blast a planet. The humans used a cargo ship with a big engine and an AI navigator to crash into a planet. The cargo bay was filled with sand, which was released at a particular distance from the planet. The ship was traveling at 10% the speed of light at that point.
You can accelerate an operating fusion device at thousands of gee, but you can't jerk it at many gee per second to make quick acceleration maneuvers. The magnetic bottle you hold the plasma in will rupture against the change in acceleration. If you want to jink hard, you have to shut down and then reboot your fusion reactors. Fusion is just going to be for constant accelerations. You can shut it down and then drive on fission for a bit. Fission will let you jerk around hard since it doesn't need a bottle. It'll actually become more responsive under a high jerk. Antimatter has the same problem as fuel, except you can't just turn antimatter off. If you flip a switch and your ship goes from ten gee to a thousand, that antimatter is going through the wall of your magnetic bottle and your ship explodes.
William Barnes A good point, but it depends entirely on the strength of the magnetic field you use. You could build either device to take high acceleration into account.
You certainly can build one to take a high acceleration into account, and shift the field forwards by moving and shaping your magnets. But to dodge and jink you don't just need high acceleration. You need to rapidly change how much acceleration you're applying. The rate of acceleration change is called "jerk", just like the rate of velocity change is called "acceleration". When you see something coming for you, you don't want to slowly burn your engine up to max power, you wanna throw the switch and BOOM go, thrown into the back of your seat. Not eased gently and then pushed back. You need that acceleration now, all of it. That's a jerk when you throw the throttle open like that. How hard you're pushed into the seat is your acceleration, but how hard you're thrown back into it in the first place is the jerk. And it's jerk that you can't maintain a magnetic bottle through, because the bottle only exerts an acceleration on the antimatter, and your spaceship is performing a jerk, and the antimatter has inertia. You'll slam the antimatter through the wall of the bottle just like how slamming on the brakes in your car gives you whiplash. You won't get whiplash if you push the brake pedal down slowly, even if you do end up pushing it down all the way at the end. But slam it down? That's a jerk. And it sends your antimatter out through the front of the windshield.
William Barnes You may be right. It may be impossible. I personally don't have what it takes to crunch the numbers myself. My physics is very sparse and very unused in the last couple decades. My sense though is that you can still overbuild a reactor for just such a purpose, and push it to its operational limit. Without numbers on either side it's hard to make a call. In the end it is way easier and cheaper to send thousands of dumb, dark rocks to hit a spot at the same time, and among them sneak a handful of nukes or antimatter bombs that need not be subjected to any jerk or snap but at the time of impact. Bombs are easier, smaller, and cheaper than any reactor.
I feel like your list is backward somehow. How are robot ninjas not more awesome than either robots or ninjas on their own? Is is because robot ninjas are constantly asking for healing?

Kamil Tomaszewski Mars would not be super reliant on the sun. Dust storms alone mean they would have large battery backup and other sources of power. It would also be very easy to blow away a stationary foil in L1.
Im so happy you mentioned The Expanse! That's the very first thing I thought of when watching this vid, and I was going to comment about it if you hadn't mentioned it anyways.
I love 'em, and thought they were reasonably 'realistic' until that frickin' Isaac Arthur started poking holes in some of their premises. Isaac did mention the books favorably in at least one video that I recall.
Weber's in-house physics are totally made up of course, but he does a great job with it in terms of composing logical strategies and realism. I generally only recommend the first 3 books, Honor starts getting a bit of superman / Mary Sue creep after that, though it doesn't get too unbearable till maybe book 6 and Weber does defocus from her to look more at other characters after that
I have a great reason why we would need the moon as a base. (Speaking to your moon video) we use the moon station to build interplanetary spaceships. Ones that can't enter am atmosphere but can hold hundreds of smaller ships that can. You build these on the moon so that we would'nt have to launch it from earth. Just send the payloads of parts every other day.
Dam Issac I was ready for terraforming Venus, what happened 😔 I'm desperate for the info, although I did enjoy this episode as always, but you covered most of this info before, as always I'm researching for my book and in my mind information will be biggest "weapon" in regards to interplanetary war or governmental control. Anyway good job but do Venus please

@Snickering Ginger Depends on how you define intelligence... and on how much their brothers in arms use their heads to protect their duller comrades. Though given the stories my dad tells about the hijinks he and other soldiers got up to in the army, I'd guess that a mildly impaired sense of self-preservation seems to be common among people who sign up for a job where people will shoot at you.
Hey Isaac, is the "Rule 1" thing a bit? You always tell us "Rule 1 of warfare" and it is different every time. Can't recall you ever climbing to "Rule 2."
I'm not actually sure, but I think I got it from some eye-rolling quip my battalion commander made to a couple of us coming into HQ one morning, about every officer and NCO having some different Rule #1 and several of them multiple ones. If my memory is right, and the Commander does have a quirky sense of humor, I suppose credit goes to Major-General Joe Harrington.
Excellent episode. The one thing that always impressed me about space combat is that I always imagined it would be electronic warfare. Basically, hijack your enemy's automated systems non and use them against that enemy. That this would be the most efficient and most realistic way to engage at a distance and would likely be the first (and potentially last) shot in any conflict. I fully agree armed conflicts will be rare if not non-existent. Especially when you consider that the concept of defense will be built around removing debris (and re-purposing it) and all the technologies involved in that. You're going to know everything in your path if your systems are clean (ie an enemy hasn't hijacked them) and have plenty of warning even if your nearest neighbor (which is likely barely a dot on the horizon with a telescope) sends something your way. You'd just deploy a harvester/assembler system and eat it somewhere before it ever got to you - since that's how you built your habitat in the first place and how you keep it safe from every natural threat you encounter. Now, the one place I do see the more traditional warfare rules is in individual or small-group actions. IE. commerce and piracy of that commerce. A person wants you or something you got, has a small, fast vessel, and yours isn't quite as small or as fast. Maybe you're a yacht or a hauler... and the pirate just wants your stuff. Even at this scale, the weapons used in conflict would likely be highly destructive - if they wouldn't also be highly visible. And the number of things that would need to break down to enable successful attempts at piracy would be rather large. But I also see piracy as a proxy for larger conflicts, and likely the only place where we'd see space warfare with anything resembling traditional tactics or tools.
Greetings. If you want to hijack a weapon control system you have a very difficult job… a. The control software is in an embedded computer at the core of the thing you’re trying to take over - so it’s in the most protected part of the target system. b. All software systems can verify themselves to make sure that the control software has not changed. Some systems can encrypt the software system in constant memory, so even if you rip open the hardware chip and connect to the data bus, you won’t be able to read the software system. c. If the weapon is using a communications link during battle, it will have an encrypted communications protocol - so the enemy can’t talk to it, or monitor what’s being sent. If someone suspects that the current encryption key has been compromised, then they can switch all weapons to a new key. d. If the embedded computer allows software updates during maintenance, then you can be sure that this feature will be turned off during any battle.
Just discovered your channel. I had already subbed, but when I saw your playlists my mind was just blown away! Everything I wanted to see and more! I think you will take up a good portion of my time from now on and I'm super stocked about it!
I love your shows man. If anyone says they can't understand you, they're being jerk for the sake of being jerks. Keep up the great work and don't let the bastards keep you down.
As always, your videos are fantastic. Every time I watch them I get even more ideas for my futuristic pnp rpgs I run with friends. Keep up the good work good sir.
Hey all I discovered this channel this summer and just finished watching all the episodes! Just want to thank you Isaac and your team that works to make this show possible! Have you thought about doing a timeline episode looking at when we could expect some of these mega-structures to be built and in what order?
Every time I see interplanetary combat mentioned all my mind wants to turn to is "that debris field would ruin so much for so long". What a tragedy, past a certain level of destruction everyone is screwed and the sun has a new accretion disk. One can even imagine a very simple missile that simply waits to see monochromatic light from a laser defense and instantly spreads its purposely fragmented payload with parts too small to target. interplanetary frag... Never mind, you just started talking about that while I typed. haha Good stuff Isaac, this is why I come back.
I remember playing a BBS game back in the day where you home BBS was you local group and the other BBS was the further group. You colonized world, organized manufacturing, made political alliances etc. But the worst, the absolute worst was not warfare with your neighbors but other empires in more isolated sectors. It really took an alliance of everyone in our galactic sector to do it and it was devastating for both sides. The effort required a lot of resources because of the time lag you didn't know how much the other civilization would develop by the time your force got there. You could send a fleet out to a relatively primitive world and by the time you got there it could be either dead (from someone else who was closer) or way more advanced than what you expected. Then you had to worry about your defenses at home. That you may have expended more resources than you should have, had a crippling galactic wide economic collapse and you are now vulnerable. Ahhh BBS days. In regards to the Fermi Paradox this might be one reason, when paired with the Great Filters, why we haven't encountered any war like intergalactic empires. War on the galactic scale without FTL (if it is not possible) is a huge....huge pain.

Oh nice. A collaboration with Godier. Check out his channel, he does a lot of really interesting coverage of current developments in the field of astronomy and has written some damn good sci fi books. In particular I recommend Supermind.
I see two other options. 1. Fire your weapons timed so they slingshot around the Sun while the planets are on opposite sides of their orbits.. Not only will they get a speed boost, they will be harder to detect at long range. 2. have your weapons platforms high up in Sol orbit, preferably somewhere in the Oort Cloud, for the same reasons.

I'd assume a capital ship could send out hundreds of these slugs per minute.
Not sure how thick the armour needs to be just take damage from just a fraction of that potential 3.6 megaton per minute.
+abz998 Not necessarily, for an example lets say that we have a 250,000 ton ship ie around the mass of 2.5 Gerald R Ford class supercarriers that means that the ship has a mass some 12,500,000 times the mass of the slug thus each slug it fires the recoil will accelerate the ship by 1/12,500,000th the velocity of the slug. 1.3% of light speed is about 3,900 km/s so the delta-V on the ship per slug fired would be equivalent to 0.312 m/s. That equates to an acceleration of 1g for every 31.44 rounds per second of fire rate, at just 314.42 rounds per second the acceleration would be 10g's if that ship has a human crew they could only fire their guns for a minute a most without killing their crew. Granted it would have fired a total of 376 metric tons of ammunition by then though that need not necessarily exhaust the magazine of a 250,000 ton ship it's only 0.15% of the mass of the ship after all.
"giant space guns". A highly scientific term.

Isaac Arthur: "Hold my volley of 10% the speed of light missiles."
It'd be simple and annoying to the opponent to just litter their orbit with our space trash while they are on the other side of the sun. Kessler Syndrome might disable their ability to launch weapons against us!
Actually that's not a bad first strike, if you want to initiate hostilities, hijack a big cargo ship of ice or something for mars then detonate the thing in orbit, and launch all your missiles just before that so the light arrives at the same time. Screw up their defenses pretty good, cause a big distraction, and probably conceal the launch.
I remember when there was less than a thousand subs when I subbed. You know for a fact the channel has grown not only when you see the almost 140k subs but the first comments you see on popular channels videos. It's beautiful to of seen Issac come so far. Love you man and keep the great work your videos are amazing and have a HAPPY Issac arthursday 😊
Yeah we've been growing like a weed, we're technically coming up on the 3rd anniversary next month but I always think of the channel really starting in spring 2016, back when there was maybe 1500 subs tops.
It doesn't seem that long since you hit 100k. You're at 139k already. I'm not at all surprised, you're an excellent science communicator and you pick really interesting thought provoking topics. Me and my friends joke that you upload 'hour and a half' 30 minute videos, because we always end up pausing and sitting in a near catatonic state for ages thinking about and discussing all the possibilities you bring up.

When I tried your link it didn't work, is this the same story?
www.sciencealert.com/a-new-twist-on-fusion-power-could-create-limitless-clean-energy
lolmao500
I've just had a read, and no, it's not. The story I've now found has exactly the same address as the one you gave, so it's weird that it didn't work directly.
The danger I see is in leaders underestimating their opponents in the 'first' interplanetary war, and being wiped out, but not before doing significant damage to any shared megastructures we have constructed by then. Just like how the nuclear defense developments (SDI and fallout shelters) made people feel more like using nukes, not less.
Amazing video as always!
Its my birthday today. Thank you for the present Issac!
Happy birthday Frank
Can't wait for the "Uplifting" episode, I'm a big David Brin fan and I know Isaac Arthur will give this topic the in depth analysis of why, when, what and hows Uplifting deserves.
Hope so, John and I are aiming at about 7000 words for the combined script, 40-45 minutes, but we're still in the first draft.
Such a daunting editing challenge simply touching on What to uplift, squids to help humans collect Manganese nodules as opposed to Honey Badgers for God only knows reasons, can take up a hour in itself. :)
"Which also means you've got a lot more money to spend on giant space guns." I just love your sense of humor, so thanks for being the audio I put on as I lay down to sleep.
The best example of this concept I've seen was actually in Zone of The Enders and ZOE2. A government of Earth asserting mastery over Mars, Mars rebelling, rebellion spreading, and long times pass between major battles. Thoroughly entertaining, to me, at least.
The game Interplanetary takes this concept and runs with it, you can use artillery, missiles, lasers, but its all on your planet, you have to beat the other guys, if you think this kind of warfare is interesting, than I suggest give it a try.
Also, the non-laser weapons all travel on ballistic trajectories, meaning you have to aim them. This can be exhilarating when you pull off an incredible shot or hilarious when someone accidentally shoots their own planet, but it implies a shockingly poor orbital point defense system for planets devoting basically their entire economies to warfare.
...Then again, they're weirdly reluctant to put ANYTHING in space. Mines, power satellites, weapons? Nope, outside the occasional special project that still includes a ground component you can shoot at.
Worbital is kinda the same thing, but its more arcady
i was watching the expanse when this episode came out...
I'm a recent subscriber. I'm Commander Shepard and this is my favorite channel on the Citadel! Mass Erect.
Rule # 1 of warfare = every single thing ever, always. I am a shipmate, a futurist and a techno optimist. I am also spiritual and cant help but be terrified of total war. I have been listening to your talks on my walk to work every day and i cant help but feel completely inspired by you. good work boss. you are a very interesting person and what you have to say correlates
.
I've never been this excited to see a notification pop up on my phone. I've thought about this topic for a long time as I've always wondered what actual warfare in space would be like due to the vast time and distance differences.
Your analogies are not only brilliant and spot-on, they generally keep me in good spirits all Arthursday long!! Thank you for another way awesome episode.

It's fascinating, imagine continent-size ships that just roleplay a fantasy world. And people can opt to forget who they are and live simple lives. Or a ship that's full of entertainment like malls, arcades, clubs, etc. Everyone living how they like, even the animals that have their dedicated ships. All your videos, really inspire sci-fi and what makes it more exciting is that we know that it is possible within the realm of physics and not some fantasy that is impossible. Inspiring the future to follow suit.

Im currently making a scifi tabletop game for my friends, and stumbled upon your channel. This is basically a treasure trove of inspiration and ways to actually ground everything in. Thanks for what you're doing, keep up the good work with these videos. Im definitely gonna be sticking around.
Isaac the gunner in da house! Very nice episode. Very cool, keeping it hard sci-fi. All sorts of awesomeness here. I think this is one of those super thick episodes which needs, nay demands multiple viewings.
Excited for the John Michael Gautier collab
I believe that in Halo:The Cole Protocol that to dodge the covenant weapons they had explosive vents which I imagine we could put small pockets that explodes with enough force to move the missile to the side
The interstellar warfare episode was really interesting imo, so I was excited to see this come.
Also, we have another Rule #1 of Warfare

If orbital lasers and missiles are the only means of planetary defense, then the ultimate counter to them would be building kamikaze droneships with a reflective mirror heatshield in front, to absorb/deflect lasers, and laser cannons of its own, to destroy any projectile-based weapon fired at it. With such defenses, the ship would be able to get close enough to the enemy planet in order to either ram it directly at relativistic speed or detonate a nuke inside its atmosphere. Such a ship would also have room for thrusters with which to evade ships or fighters sent to ram into it.
These small ships could be launched either from your planet directly or from a supercarrier capital ship.
OMG AWESOME SUBJECT SIR THX!!

Isaac Arthur, you are my biggest inspiration, not many people inspire me because who else makes such good Sci-Fi videos?

Hey! Your megastructures-ringworlds episode is coming out on my 17th birthday! Thanks in advance for the probably awesome (who am I kidding, DEFINITELY awesome) birthday gift!
OH thank you ! I am sick and a new episode is the cure!
This is such an underrated channel.
People may not become more peaceful over time for any moral or philosophical reasons. But as society becomes more wealthy *and* that wealth is spread more evenly among the population, the root cause of war - greed - would lose force. If society becomes as widespread and wealthy as shown in videos like this one, war would become as undesired (and hopefully as rare) as widespread famine or pestilence. That may be an over-simplification of course, but I'd like to think it is at least basically correct.
Quite so; just look at ISIS. But by and large I agree with your original point. These days religions are just as divisive as politics are... but maybe someday we can solve those problems just as science and technology have solved so many others (though admittedly they've created a few too; I think we're all happier with them than we would be without them)
Jason Toddman depends on the fragility of your society. If war is mostly a function of both states throwing disposable income and robots around as long as it is balanced, it might be very common indeed. If brutal conquest is the consequence for losing, but the only consequence for fighting is a tax on people who already make more than enough to provide for themselves, that makes the first rule of war "don't lose."
If the cost to your society is the equivalent of "you can only buy a new cellphone, laptop, and nice car every year instead of every 11 months," and all your cost is coming out of imaginary appetites anyway, I could well see a society putting a lot of its GDP toward weaponry and being more than willing to nuke enemy robots using their own robots at even minor provocations. The Soviet union largely lacked severe poverty for most of its existence, but had little issue chucking away massive amounts of resources on war machines. America has been wealthy since its inception, again with absolute poverty being a rare occurrence, and it spends more on war machines than the rest of the world combined. If your people live under fully-automated luxury communism or a classically liberal automated capitalist juggernaut where the poorest in your society are working 15 hours per week to live a lifestyle equivalent to the upper middle class of today, spending a considerable portion of your expenses on death-less warfare may seem attractive, especially if you think you can get better deals with the threat of actual violent warfare.
Jason Toddman in fact, I would go so far as to say that in the past, abundance has brought a lust to test one's new capabilities of destruction, not an era of peace.
Like, it's a bit of a weird example, but when I've been in Minecraft factions, where luxury confederal communism tends to be the default mode of societal production and distribution, there are a few distinct phases. Usually warfare occurs early on, when a decent lifestyle is hard to earn, and in late-game skirmishing, where idle hands start going into automated warfare without much expense to quality of life, with occasional large-scale successful raids sending someone a few levels of development back. I feel a lot more willing to throw nukes around when they are being auto-assembled by robots from raw ore. Further still, I've discovered that the things necessary for industrial-scale warfare are also necessary for industrial-scale civilization.
You do not go hunt a thousand creepers to annihilate the enemy military complex or carve out million-block areas. You build skyscraper-sized mobgrinders that produce more TNT and arrows than you know what to do with. You don't painstakingly hollow out the nether from bedrock to bedrock to limit enemy activities. You again get the industrial base to do such things first, not because you want war, but because that is simply the cheapest way to churn out millions of blocks of raw material for building more stuff.
Having no real human cost to starting wars would, one should presume, make doing so more likely, not less. When it's our drones vs. Theirs and nobody starves either way, war is pretty attractive.

This episode, and a previous one I watched, reminds me of two space combats from two difference authors. Kim Stanley Robinson, and Ian Douglas (William Keith Jr.).
In Robinson's 2312 there was an attack on a solar shield. It was planned with a point defense system in mind. Several small pea sized pebbles were fired at various places around the solar system to converge on a point on the sun shield.
In one of Ian Douglas' military sci fi series he had a human fleet sand blast a planet. The humans used a cargo ship with a big engine and an AI navigator to crash into a planet. The cargo bay was filled with sand, which was released at a particular distance from the planet. The ship was traveling at 10% the speed of light at that point.
I really like how everything in the number 1 rule of warfare lol
I like the little running joke you have about Rule #1 of Warfare. Cracks me up every time.
You can accelerate an operating fusion device at thousands of gee, but you can't jerk it at many gee per second to make quick acceleration maneuvers. The magnetic bottle you hold the plasma in will rupture against the change in acceleration. If you want to jink hard, you have to shut down and then reboot your fusion reactors. Fusion is just going to be for constant accelerations. You can shut it down and then drive on fission for a bit. Fission will let you jerk around hard since it doesn't need a bottle. It'll actually become more responsive under a high jerk. Antimatter has the same problem as fuel, except you can't just turn antimatter off. If you flip a switch and your ship goes from ten gee to a thousand, that antimatter is going through the wall of your magnetic bottle and your ship explodes.
William Barnes
A good point, but it depends entirely on the strength of the magnetic field you use. You could build either device to take high acceleration into account.
You certainly can build one to take a high acceleration into account, and shift the field forwards by moving and shaping your magnets. But to dodge and jink you don't just need high acceleration. You need to rapidly change how much acceleration you're applying. The rate of acceleration change is called "jerk", just like the rate of velocity change is called "acceleration". When you see something coming for you, you don't want to slowly burn your engine up to max power, you wanna throw the switch and BOOM go, thrown into the back of your seat. Not eased gently and then pushed back. You need that acceleration now, all of it. That's a jerk when you throw the throttle open like that. How hard you're pushed into the seat is your acceleration, but how hard you're thrown back into it in the first place is the jerk. And it's jerk that you can't maintain a magnetic bottle through, because the bottle only exerts an acceleration on the antimatter, and your spaceship is performing a jerk, and the antimatter has inertia. You'll slam the antimatter through the wall of the bottle just like how slamming on the brakes in your car gives you whiplash. You won't get whiplash if you push the brake pedal down slowly, even if you do end up pushing it down all the way at the end. But slam it down? That's a jerk. And it sends your antimatter out through the front of the windshield.
William Barnes
You may be right. It may be impossible. I personally don't have what it takes to crunch the numbers myself. My physics is very sparse and very unused in the last couple decades.
My sense though is that you can still overbuild a reactor for just such a purpose, and push it to its operational limit. Without numbers on either side it's hard to make a call.
In the end it is way easier and cheaper to send thousands of dumb, dark rocks to hit a spot at the same time, and among them sneak a handful of nukes or antimatter bombs that need not be subjected to any jerk or snap but at the time of impact.
Bombs are easier, smaller, and cheaper than any reactor.
Well I'm making a book about a conflict between earth and Mars, and I'm kinda respecting the science you talked about today

Is is because robot ninjas are constantly asking for healing?

Just discovered this channel and planning my binge watching. About 100 videos of about 30 minutes average playtime. That's 50 hours of material. 1 pizza every 10 hours, that's 5 pizzas i need to get through it all. 1 liter of coca cola every 2 hours, that's 25 liters of coca cola i need. 1 bag of chips every 1/2 hours that's 100 bags of chips. Alright, I can do this, I'm off to stock up, see you on the other end.
I would like to remind everyone to be at their combat stations in 2 hours. We have an incoming missile volley.
I just got caught up on the Expanse, great show. Glad to see you're doing a video with Godier, should be a good one!
I've never been dedicated to a channel so much, wubba lubba dub dub!

You can use a foil to block the light between Sun and Mars. Wouldn't it kill them? Its worth to consider :)
No, they set up another foil to bounce light round the side, or a fusion reactor in orbit.
Kamil Tomaszewski
Mars would not be super reliant on the sun. Dust storms alone mean they would have large battery backup and other sources of power.
It would also be very easy to blow away a stationary foil in L1.
I haven't tried it, but I have heard Children of a Dead Earth is a game/sim that offers these scenarios.
I wonder if Isaac is any good at Planetary Annihilation? hehe...
Or Children of a Dead Earth.
Planetary annihilation doesn't have orbital defense lasers
I absolutely love the Space Warfare videos! Thanks for putting out a new one!!!
Ayy happy arthursday
Im so happy you mentioned The Expanse! That's the very first thing I thought of when watching this vid, and I was going to comment about it if you hadn't mentioned it anyways.
Has anyone ever read the honor Harrington books they are all about space warfare and they are awesome
I love 'em, and thought they were reasonably 'realistic' until that frickin' Isaac Arthur started poking holes in some of their premises. Isaac did mention the books favorably in at least one video that I recall.
Weber's in-house physics are totally made up of course, but he does a great job with it in terms of composing logical strategies and realism. I generally only recommend the first 3 books, Honor starts getting a bit of superman / Mary Sue creep after that, though it doesn't get too unbearable till maybe book 6 and Weber does defocus from her to look more at other characters after that
thank you for once again blessing us all with your unparalleled brilliance

I have a great reason why we would need the moon as a base. (Speaking to your moon video) we use the moon station to build interplanetary spaceships. Ones that can't enter am atmosphere but can hold hundreds of smaller ships that can. You build these on the moon so that we would'nt have to launch it from earth. Just send the payloads of parts every other day.
Dam Issac I was ready for terraforming Venus, what happened 😔 I'm desperate for the info, although I did enjoy this episode as always, but you covered most of this info before, as always I'm researching for my book and in my mind information will be biggest "weapon" in regards to interplanetary war or governmental control. Anyway good job but do Venus please

Hey Isaac, is the "Rule 1" thing a bit? You always tell us "Rule 1 of warfare" and it is different every time. Can't recall you ever climbing to "Rule 2."
Yeah its a running gag, I explained it back in Space Warfare when I started it, I feel like mentioning it in the nominal sequels would spoil it :)

i0.kym-cdn.com/entries/icons/facebook/000/012/132/thatsthejoke.jpg
I'm not actually sure, but I think I got it from some eye-rolling quip my battalion commander made to a couple of us coming into HQ one morning, about every officer and NCO having some different Rule #1 and several of them multiple ones. If my memory is right, and the Commander does have a quirky sense of humor, I suppose credit goes to Major-General Joe Harrington.
Excellent episode. The one thing that always impressed me about space combat is that I always imagined it would be electronic warfare. Basically, hijack your enemy's automated systems non and use them against that enemy. That this would be the most efficient and most realistic way to engage at a distance and would likely be the first (and potentially last) shot in any conflict. I fully agree armed conflicts will be rare if not non-existent. Especially when you consider that the concept of defense will be built around removing debris (and re-purposing it) and all the technologies involved in that. You're going to know everything in your path if your systems are clean (ie an enemy hasn't hijacked them) and have plenty of warning even if your nearest neighbor (which is likely barely a dot on the horizon with a telescope) sends something your way. You'd just deploy a harvester/assembler system and eat it somewhere before it ever got to you - since that's how you built your habitat in the first place and how you keep it safe from every natural threat you encounter.
Now, the one place I do see the more traditional warfare rules is in individual or small-group actions. IE. commerce and piracy of that commerce. A person wants you or something you got, has a small, fast vessel, and yours isn't quite as small or as fast. Maybe you're a yacht or a hauler... and the pirate just wants your stuff. Even at this scale, the weapons used in conflict would likely be highly destructive - if they wouldn't also be highly visible. And the number of things that would need to break down to enable successful attempts at piracy would be rather large. But I also see piracy as a proxy for larger conflicts, and likely the only place where we'd see space warfare with anything resembling traditional tactics or tools.
Greetings. If you want to hijack a weapon control system you have a very difficult job…
a. The control software is in an embedded computer at the core of the thing you’re trying to take over - so it’s in the most protected part of the target system.
b. All software systems can verify themselves to make sure that the control software has not changed. Some systems can encrypt the software system in constant memory, so even if you rip open the hardware chip and connect to the data bus, you won’t be able to read the software system.
c. If the weapon is using a communications link during battle, it will have an encrypted communications protocol - so the enemy can’t talk to it, or monitor what’s being sent. If someone suspects that the current encryption key has been compromised, then they can switch all weapons to a new key.
d. If the embedded computer allows software updates during maintenance, then you can be sure that this feature will be turned off during any battle.

Hey all I discovered this channel this summer and just finished watching all the episodes! Just want to thank you Isaac and your team that works to make this show possible! Have you thought about doing a timeline episode looking at when we could expect some of these mega-structures to be built and in what order?
in time you need to get all this great content on some dvds so I can buy them
Every time I see interplanetary combat mentioned all my mind wants to turn to is "that debris field would ruin so much for so long". What a tragedy, past a certain level of destruction everyone is screwed and the sun has a new accretion disk. One can even imagine a very simple missile that simply waits to see monochromatic light from a laser defense and instantly spreads its purposely fragmented payload with parts too small to target. interplanetary frag... Never mind, you just started talking about that while I typed. haha Good stuff Isaac, this is why I come back.
I remember playing a BBS game back in the day where you home BBS was you local group and the other BBS was the further group. You colonized world, organized manufacturing, made political alliances etc. But the worst, the absolute worst was not warfare with your neighbors but other empires in more isolated sectors. It really took an alliance of everyone in our galactic sector to do it and it was devastating for both sides. The effort required a lot of resources because of the time lag you didn't know how much the other civilization would develop by the time your force got there. You could send a fleet out to a relatively primitive world and by the time you got there it could be either dead (from someone else who was closer) or way more advanced than what you expected. Then you had to worry about your defenses at home. That you may have expended more resources than you should have, had a crippling galactic wide economic collapse and you are now vulnerable. Ahhh BBS days.
In regards to the Fermi Paradox this might be one reason, when paired with the Great Filters, why we haven't encountered any war like intergalactic empires. War on the galactic scale without FTL (if it is not possible) is a huge....huge pain.

You proved how costly warfare is at this scale, however, one of the key components to freedom is preparation for war.
Oh nice. A collaboration with Godier.
Check out his channel, he does a lot of really interesting coverage of current developments in the field of astronomy and has written some damn good sci fi books. In particular I recommend Supermind.
I see two other options. 1. Fire your weapons timed so they slingshot around the Sun while the planets are on opposite sides of their orbits.. Not only will they get a speed boost, they will be harder to detect at long range. 2. have your weapons platforms high up in Sol orbit, preferably somewhere in the Oort Cloud, for the same reasons.
I love this channel and all the work you guys do. This stuff will propel us into the future.
Love this channel. Thanks
