A number of thoughts concerning the ramifications of building an FTL warp drive... 1) If an FTL warp drive is possible, I am positive the human race will figure it out. 2) There's a non-zero chance that other intelligent species (if any) will begin to be concerned about the human race once we develop some kind of FTL travel capability. 3) Even with the ability to travel infinitely fast, it is impossible to completely explore an infinitely large universe.
@@sfurules My dude. Any amount is a measurable amount. Just because we haven't figured out how small or large that number is doesn't mean that it can't be measured.
Did videos of just become incredible with the way you present them, I know I keep saying this.. but it’s because it is true! I’ve been following everything science especially with space, cosmology, astronomy, etc. from as early as I possibly remember, too.. so well done!
The Planck length is not as much a voxel size as it is blur radius; things bellow that length get blurry, but they don't snap to a grid. It's like reality bellow that scale is out of focus, or is jittery and suffers from motion blur.
@@terranspaceacademy if electrons didn't exist till interactions, there would be no difference between elements. Electrons exist in every configuration possible for each electron cloud of each element until we interact with.
When I was a teenager and our first landing on the moon was a few years away, this was utter, absolute fantasy. Clearly, such is no longer the case for warp drives, as is true with so much of what was science fantasy all those long decades ago. What we have accomplished in the meantime is, it appears, difficult to appreciate without some grasp of where we've come from. So while I think the concerns of those who say this will never happen deserve a hearing, I am absolutely convinced that one day, sooner than we think, warp drive will be a reality.
With a few tweaks this gets interesting. We may not know for sure any time soon but this tech may already be in operation, shielded from the public. In 1993, Lockheed Skunkworks CEO, Ben Rich, told a class of aerospace grads at a grad ceremony "We have the ability to bring ET home" and was known to write out " *U*n- *F*unded *O*pportunities" and how they benefited the black aerospace industry greatly.
@@terranspaceacademy Any form of faster-than-light-(FTL) propulsion will cause a grandfather paradox. You can find articles on the Internet and UA-cam videos that talk about the causality disorder with all FTL drives. This is why I believe FTL travel will never be possible. If FTL travel is possible, a grandfather paradox can be unintentionally triggered, which means the immediate destruction of the entire universe. There are different gravitational fields in space and therefore time flows differently, and FTL travel between such objects of different masses will cause time paradoxes and the destruction of causality - (grandfather paradox). It's a pity you don't discuss this issue because it is the main problem with faster-than-light travel (FTL).
Im old enough to remember watching original, first run StarTrek back at my parent's home as a young teenager. I've been a devoted space creature ever since. I got to fly but not go into space. But no, without FTL we are NOT going to seek out new worlds outside our solar system. New civilizations? Well, that would be nice, but I'm not sure they are remotely nearby. If FTL turns out to be impossible, we have this space only, or I guess virtual reality space. The latter sounds more likely at the moment. I certainly have followed Sonny at NASA, but he has made limited progress and I don't think NASA is totally onboard with him. I like to think, nature found a way to put all these worlds out there and we will find a way to get there.
@@terranspaceacademyno, as I explained above it is possible to do it sub-light assuming habitable worlds aren't spread too far apart, eg 5 to 10 light years apart on average., and we can get to speeds above 10% of light speed (though the faster the better). Generational ships which could last a hundred years or so should be feasible whereas ones which travel at our current top speeds and take multiple thousands of years to make the trip are much less feasible. Such colonisation though would end up with human descended colonies throughout the galaxy given enough time but they would be physically pretty much isolated - there would be no centrally controlled galactic empire or federation. Though those in systems relatively close to each other would be able to communicate with each other by radio.
generational ships are thought by many to be unfeasible. And consider, TESS and Kepler have to date discovered roughly 5,000 exoplanets. Not 1 is earth-like. The "Rare Earth" solution to the Fermi Paradox shows that a large number of chance factors have made earth so remarkable for sustaining life. The nearest true earth like planet could be thousands of light years distant. Another advanced civilization could be tens of thousands of light years away. I haven't done the math, but it would seem that the USS Enterprise was able to travel at more than a thousand times the speed of light to go to the places it did during a "5 year mission". In fact today, the Star Trek series has just opted for "spores" that instantly deliver the ship to any spot in the galaxy.@@davidwebb4451
I too grew up watching the original. It's amazing how spot on was StarTrek in certain respects. Like that effect of the ship as it activated the warp drive, that's exactly how it would look like to an observer I think, or that they had to move out of a solar system to go to warp speeds, and they would use "impulse" speeds when nearby planets/stars or inside star systems for obvious reasons. I only got to fly in pc simulators. I don't think we'll see something of this sort in our lifetimes, I mean, I'd hope we would, I just kinda doubt it. Yes, there's so much to see, just like earth was massive to explore with horses, it got small with airplanes, in the same way, maybe with something like this, other star systems in our galaxy could become accessible.
We first need to figure out what makes gravity, is it a particle is it a wave or is it both? And can we amplify it like sound or electricity? you would need a lot less energy to make a warp drive feasible.
technically, opening a hole is space and time and traveling through it is a "worm hole" and not a "warp drive". Warp drive is shrinking the space in front and expanding in back
Could we bend space in the same way warp drive works to make shuttles (like in Star Trek) that appear to be floating (from the perspective of those on the ground)? Also 2nd question: what happens if 2 of these “warp fields” (bending of space time) collided?
just recently new simulations of it just came out alike a couple o so weeks ago and people and scientists irl all around the world are slowly warming up and starting to take the warp drive seriously even if FTL isn't possible STL warp drive would still be absolutely revolutionary I cannot tell you how excited I am
The only problem if what you are suggesting is to focus a majority of time, resources, and funding to a warp drive is problematic because mathematically possible in reality there's a greater chance that a warp drive due to impractical processes and by a scientific limitation E=MC2 just isn't feasible. Not to say that what can be learned wouldnt be valuable or useful. But to put most of our eggs into one basket one that is only possible mathematically would be a wager I wouldn't make.
Using two circular opposite rotating Casimir plates may produce negative & positive energy states at their closest point, which according to Hermann Bondi results in runaway motion towards the positive energy state. These plates can be nested to enhance said effect.
I recall a YT video based on a paper that does what you describe but with negative energy only, but you say positive? I’m not questioning you I just got curious. The only paper I recall regarding positive energy is a rotating energy mass 10% of the Sun even with optimized emitter field, which is kind of unfeasable still. There’s another paper regarding negative energy but utilized as Quantum Tunneling by lowering the wavefunction of the bubble, though the paper didn’t address particles tunneling (hawking radiation?) inside the bubble or even vacuum decay.
War Eagle🦅🦅🦅 what a great name for a horse😊… what is the farm anywhere near Auburn/Lee County? I spent a little time there learning mechanical engineering😄. Thanks for another great video!!
6:00 Little clarification here, its not a continuum if you are discussing Voxels. Least I am pretty sure that is the case and this simple fact is one of the issues with QM and GR being merged.
As always double check and make sure that is the case but I am 98% sure Continum means just that, a constant space manifold with no breaks or non-interpolated regions. Its a bit nitpicky I know but just feel when talking about this sort of stuff its important as it may help understand the topic at hand and the issues GR poses to QM as one has discrete jumps and energy levels where as the other is a smooth transition from one to the other. Attempts to find discrete energy levels in gravity have all failed. That coupled with the fact QM smears particles across a probability yet gravity defines mass as a point are two of the more major issues with unifying them. It sounds like it would be easy on the surface but it is anything but.@@terranspaceacademy
I'm very envious of future generations, getting tech we never thought possible, tools to go more places and see farther. It might not come to traveling to distant objects because of the time factor, but we can continue making better telescopes and computers and bring them to us.
I have some black hole concepts that might get us up to a fraction the speed of light but it works like a big gravity pump. One pulls a smaller one forwards then gets cut off do to grating closures of a dyson sphere, then it gets pulled backwards and like this, a piston like effect and the gravity waves are then shunted with particles that are roughly fractions the speed of light.
@@terranspaceacademy Yes we could actually use this one if we could recreate something similiar to a soliton wave or if we could create a runaway black hole we could follow it with a really strong sail type system but it would have to be a very long sail to avoid damage from the black holes gravity. I then tried to create a sail that would basically convert the gravity into mechanical energy but its innefficient as far as I know.
There is no limit on how fast spacetime can expand. Just on how fast something can travel through spacetime. The expansion may be like a gas in a vacuum. Powered by entropy.
Mathematically consistent goes a long way but yes, experimental evidence is crucial. That is why Dr. White is trying to get positive results from a small experiment.
Space still isn't a flat plane that can be bent. It is a VOLUME. It MAY be possible to compress or expand it, but there is ZERO empirical evidence of that.
I know it is a dumb question, but what happens when propeller rotates in deep space? (Like a ship propeller or fan blade rotating at high speed with electric)
Nothing really except they would over rev without a governor. No resistance = high rpms. No movement though. Unless you can create a virtual particle propeller... Hmmmm...
@@terranspaceacademy Has anyone ever tried or experimented with it? What does rocket thruster or ion thruster do? Push ions or gas out in a certain direction to create momentum. If there is nothing in space, how is rocket able to propel forward? What would happen is propeller is radially mounted or axial? Can Lorentz force work in space to propel?
What about this Warp Drive? positive charge shell with a negative interior +(-(-(-us)-)-)+ like a russian doll. Then reverse polarity of the next outer shell +(-(-us)-)+...+(-us)+ opisite charges do you think this has more potential than that one.
Trying to interpret the experiment? Are they basically trying to make a small gravity wave generator and then try to detect that gravity wave from the generator with a small gravity wave detector?
So many ideas about warp drive. Maybe we can do a thought experiment. Thought experiment of a warp drive equation. This is the equation. (positive infinite energy+ dyson sphere(magnifier)+ warp drive ship × radiation thermo (temperature))= warp drive engine. Let me explain. First the warp drive ship can only be flown by (AI) machine for now, because of radiation. Ok exotic matter, exotic negative matter for warp drive is a waste of time. It's a dream or nightmare. You must use what's in front of you, your environment. For example, in the Alaskan frontier, you might have to cut trees to build your home or use snow for drinking water, or if your an Alaskan eskimo, build your igloo home out of ice blocks or cut thur ice to fish to get food, etc,etc,etc. Again you must use what's in front of you, your environment. Ok, look at the equation again. Remember what i said, use what's in front of you. The sun is our positive infinite energy power source for warp drive travel, not exotic matter. You would put many giant solar deflector array dishes around the sun. Built by (AI) super computer. All the deflector dishes will redirect the sun energy into one highly focused concentrated energy beam and aim it to the dyson sphere magnifier. For example, how you can start a fire useing a magnifying glass with the sun. The magnifier dyson sphere, will be built by a (AI) scientist and engineer with infinite quantum processing speed. The (AI) artificial intelligence will figure out how to harness, how to collect, how to magnify that energy beam to the correct intensity. I think the (AI) won't use glass or mirrors. It will use something else . That beam will be aimed at the warp drive warp coils, and the ship will go into a spacetime tunnel. Now you might say, it's in the spacetime tunnel without a internal power source to maintain power to the warp coil static bubble shell. I know look at the equation again. Next is radiation thermo temperature. Remember, remember, we will use what's in front of us, our environment. We will use that radiation thermo temperature that energy, that friction, that heat, that radiation that surrounds the warp bubble to maintain the warp coil running. You see, you see, we don't need to bring an internal power source on the ship and no exotic matter required. We need to use that radiation thermo temperature and somehow convert use it's energy, into energy that the warp coils can use, built by artificial intelligence (AI). And the ship will travel without an internal power source in the spacetime tunnel. And you can stop the ship. Just block off that energy from the ship's warp coils. I guess useing some kind of force field built by (AI). And the ship will stop. Also, also i think, if we're lucky enough to have lived around a 2 yellow binary star system, it would be easier. We would have even more energy to Jumpstart the warp coils on the ship. More yellow stars equals more energy for the warp coils to work correctly. And Dr harold g sonny white talked about the ship being 10 meter diameter. But if you don't bring a internal power source and put the (AI) pilot in a tiny black box. You maybe can make the ship 2 meters in diameter or maybe 1.5 meters. smaller ship means less energy requirements. Maybe dr harold sonny white can run computer simulations useing 1 or 2 yellow stars, when he's not busy and post the video so i can see it.
@@terranspaceacademyif you decide to run the computer simulation. Maybe use a giant yellow star 10 to 100 times the size of our sun, with the solar deflector array dishes around the sun. Maybe the dyson sphere magnifier can be smaller, because, we have all that energy. Or, if going to use a 2 yellow star binary put the deflector array dishes around the equator circumference of both yellow stars both. 2x the power for the dyson sphere magnifier. To Jumpstart the warp coils on the ship.
What kind of interstellar/intergalactic pollution of the environment can be expected to leak from warp drives? How are quantities of negative energy expected to behave upon loss of containment?
No. You would just drop out of warp. There are theories that photons at the front of the ship will be shifted to extreme gamma rays that would be released on collapse of the bubble.
@@terranspaceacademy I asked no yes/no question there. My point is that the concentrations of negative mass required by the Alcubierre drive would be self-repulsing and thus necessitate confinement and have the potential to leak from it -- so that there'd be cause to ask what the impact on the cosmic environment would look like assuming negative mass pollution from alien drives over eons... analogous to the impact on Earth's atmosphere of our own combustion engines.

@@terranspaceacademy We need to break it down into precise steps so that we can run experiments and develop our understanding of graivyt waves and how they can be produced technologically.
Warp drive would be great for sub light travel but I think you'd need to look time travel for its ability to change spacial position in a time vector or volume
Travelling faster than light means Travelling back in time. There isn't a universal speed limit. You can travel at any speed, and the amount of energy you need to accelerate from 0 to 1 m/s is the same you need to accelerate from 1e20 to 1e20+1 m/s. However, space is time. The time dimension changes at a rate of 1s every 300,000kms. This means that when you reach, say, proxima Centauri, you are 4.2 years in time away from home, so you need to add that to the time it took for you to get there (called "proper time"). So from a stationary observer, it appears that you traveled "slower than light". A warp drive wouldn't automatically change that. If you could teleport to proxima in an instant (that would be traveling at the speed of light), proxima would still be 4.2 years away in time. However, a warp drive may be used to bend time. Arriving any time before 4.2 years in proxima (no matter how much proper time you subjectively experience, your own trip within the warp bubble could take an instant or thousand years) means you effectively traveled back in time. Doing the round trip continuously would ultimately land you on the Earth before you first left.
What you get if you would try to put a person inside of time dilation device? And what happens if we dont add too much of shielding? We dont actually destroy earth or matter but actually create a gravity wave. Interesting to think about.
Can you amplify the energy in the toroidal by creating synchronization waves or complimentary waves or decrease it with destructive or cancelation waves?
I have a few ideas to make gravity drives, as this is something I always loved. A nuclear powered drive can be made and we already have the tech to make it happen, it only works in low gravity fields, the other is much more exotic to achieve and is definitely on a wish list and somewhat only if it's available as a resource locally in the solar system. That resource has not been found or confirmed, but may actually be found in the future, as some science facts say's it may very well be available. Hint is a Brown Star . I said that on 2023-11-12 how to curve space without energy.
Spacetime is only conjoined when looked at from one perspective. Time is the measurement of movement, from subatomic quarks, to browning motion, and the larger permutations with mass. If space can bend, causing any baryonic matter or electromagnetic waves to curve along their paths; then time can be bent too. There is so much more to learn and not enough time to learn it. While I agree that we should be multiplanetary, I'm not sure we are ready for it nor do we deserve it. Is it possible that we find a warp speed option? Yes, but I am sure the odds are not really in our favor.
In my attempt to understand this warp drive gradient, I researched how skin voltage, which is a potential, affects drag, and it turns out that increasing the skin voltage of vehicle, lowers drag.
@@terranspaceacademy I believe it was in our atmosphere. I don't recall the test conditions but could find the test report. A bar of metal, electrified to high voltage, then tested for laminar vs turbulent flow.
Roxels -- you kind of belie the Lorentzian metric of spacetime by discussing the Planck bounds in terms that call on the inappropriate Euclidean intuitions of the audience. The comparison with pixels implies a stable grid -- which works in the Euclidean setting but not the Lorentzian setting. Length contraction, time dilation and all that...
@@terranspaceacademy Idk, Last I heard vacuum energy was positive. Just a lot lower. Actual negative mass with negative gravity is a whole different kettle of fish. It doesn't even make sense that negative mass would clump together.
@@terranspaceacademy what do you mean "negative mass requirements can be met by vacuum energy"? not only can we NOT make use of vacuum energy, it is also definetly positive, how would this create negative curvature ? use this to calculate: Gμν + Λgμν = 8πGTμν, there's no such thing as negative energy/mass, which is required for the negative curvature needed in the warp drive
@@terranspaceacademyHe explains the math. I grant the math works. But it's like negative sheep. It works in math. It works in concept but in the real world there is no way to have negative sheep. Even if you try to make one out of anti-matter you still end up with a positive number of anti-sheep. Not negative sheep. My objection isn't that the math doesn't work. It's that it relies on impossible things, therefor making the reality of the drive impossible. Impossible is a far cry from plausible.
That's not exactly what a planck distance is. It is the smallest distance with meaningful distinction or measurable interaction. That doesn't mean things can't exist be happening smaller scales, but that they're effectively considered to the be same, and no meaningful difference in distance can be determined. It's an event horizon on the small scale. IE the horizon of perceivable/interacting contiguous events.
People wanna tackle crossing the diatance but dont consider just trying to slow down time instead.. Some kind of temporary black hole generator/projector targeted in front of the vessle could slow down time and accelerate a vessel towards the black hole (gravity).. the trick would be how to generate and degenerate black holes and how to have enough power to do so... constantly reprojecting a new gravity well to fall into.. having a pull on effect much like electric motors work.
Stand on the left and right, and walk down the center in the opposite direction of motion. You will get nowhere fast. Oh wait, I'm confusing treadmill and moving walkway.
For some reason people don't know about the 1 realistic method for interstellar travel. If a ship leaves our solar system traveling at a constant 1g acceleration rate it would get to Alpha Centauri in 3.6 years (7.3 years would pass on Earth) and this includes turning the ship around halfway to decelerate. It would achieve about 95% light speed after about 1 year. A 10 ton ship would require a mere 10 tons of continuous thrust. This is by far the fastest way we can get to other worlds and the ship would have gravity the whole way. All that is needed for this is a true fission rocket that consumes uranium or plutonium only. They are both jittery atoms that are on the verge of fissioning all by themselves. There should be a way to get them to fission in a linear fashion. What's needed is a controlled, time released nuclear explosion. In an atomic bomb fission occurs when neutrons hit uranium or plutonium nuclei. This is because they will not tolerate an increase in mass. Due to the equivalence of mass and energy the same should be true if you infuse them with energy. I made a video which illustrates 3 new true fission rocket concepts, "Best method for interstellar travel". With the constant 1g acceleration method a ship can span the entire diameter of our galaxy in 24 ship/ 113,000 Earth years.
@@terranspaceacademy A true fission rocket should not be too complicated. All proposed fission rocket concepts incorporate hydrogen or xenon in their process. This automatically makes them unsuitable for interstellar travel because you can't bring thousands of tons of that with you.
@@terranspaceacademyThe fuel requirements to continuously accelerate for long periods at 1g, eg a year or more, and then decelerate to get to your destination are gigantic. Fission won't be good enough, you might get closer with fusion but you would probably require total fuel conversion ie anti-matter.
People should consider this: at a particle accelerator, we propel an electron (for example) to extremely close to the speed of light, and nothing spooky happens. We know of no way to make anything go any faster. If we can’t make a single electron do it, there’s no way to make moles and moles of electrons do it.
@@terranspaceacademy everyone already knows that lol. And those effects apply to everything external (from the particle’s point of view). Nothing changes in the rest frame of the particle. But thanks for making this content!!
Hold on, if we can accelerate one electron to near the speed of light, then there _is something_ we can use to accelerate several moles of electrons to the speed of light. It is the same thing that the Ancient Egyptians used to build the Great Pyramids, despite them seeming to not have the technology to do so, today; Patience. 💡
Didn't Star Trek come out in 1966? Three years before we got to the Moon.. I lived in a semi rural area in the '70s, and we got the three network stations, two independent stations ( that aired Star Trek) and PBS ( that had Nova and Dr. Who). In some of Alan Dean Foster's science fiction tales, the FTL ships had the engine out front, and the ship fell towards the warp, without ever getting to it.. Star Trek predicted...or influenced....reality more than once. The old flip phone had to have been inspired by the communicator, and there is transparent aluminum....( Alon). Great video, by the way...
Star Trek was first broadcast in 1966 but the two pilots were filmed in 64 and 65. In the third feature film in 1984 the Enterprise is said to be 20 years old, which was true of the original filming model as seen in ‘The Cage’. Roddenberry first started pitching the idea of Star Trek earlier than either pilot was developed, so perhaps it can be said that it started in 63.
Actually the plank limit is just the smallest that can be MEASURED, not necessarily the smallest that can exist. If all you have to measure with is an inch, then the most accurate you can measure is an inch anything smaller is only an estimate. And no, the shifting gravity is one of the slowest ways to travel - but would use the most minimal amount of fuel which is how the small asteroids enter an L4/L5 position. they will also only stay there for about 400 years, then move out of those relatively stable areas.
It's tough to say what might exist below what can be measured in any way. The gravity lanes aren't the propulsion system. They are the highway. Amplifying our speed and creating a true highway/shortcut.
The Miguel Alcubierre papers where written hundreds of year before the Miguel Alcubierre you explain in the video lived. I literally wrote those papers hundreds of years prior, having already built a Warp Drive Engine. By the way, I was Albert Einstein, and the writer of the Miguel Alcubierre papers

I hope I see this in my lifetime. One gotcha is the shifting of electromagnetic waves to higher and higher energies. It would fry organics. I am curious about the actual physical mechanism that is the "working" part of this drive. Does anybody have any idea what it would be? Some kind of coil or capacitor? Or is it all theoretical and they haven't worked that part out yet? Edit. Maybe it won't fry people. The lecture makes it sound like your acceleration and velocity would be zero. Interesting.
There unfortunately would still be frequency shift, as you'd essentially be sitting inside a standing wave. However, by the time that the technology for this sort of thing gets worked out, we'd be long past our current "orbital scarcity" state, so I'd worry more about micrometeors & such.
6 years, from walking on the moon to 6 years from walking on the moon again, 2 years as of this comment. On the surface it looks like not a lot of progress. But that's far from the case, starting with the cost of getting to the moon has dropped from an average $50 billion, in today dollars, per trip decades ago to an estimated $10 billion in today's dollars in a few short years. And while the Apollo missions could reach equatorial regions and some higher lunar latitude on the near side of moon, the Artemis missions will use near rectilinear orbits that can reach anyware on the moon for much less cost for 21 days with the lunar gateway providing a permanent base for power, life support and communications relay for missions to the back side of the moon and polar regions. The Artemis missions will be doing far more than the Apollo missions for much less cost. Maybe we might bemone that it's taken us this long to go back, but we shouldn't sell Artemis short. What's taken us so long has more to do with national want and will than technology. I personally believe we should work to a solar pannel manufacturing base on the moon and a lunar spin launch platform to launch them to Earth geosynchronous orbit and beam beam power 24/7 to locations on earth, to cover peeks in demand and lulls in supply. Just to make a point, Spinlaunch current suborbial platform on earth if placed on the moon could launch with a pannels with a lunar escape velocity. If we prioritize this, we could have this up and running in 20-30 years so that Over the next 50 years we can reduce fossil fuel use virtually eliminate it in 100 years. Space based solar power beaming to earth would allow us to use lithium for transportation energy storage and not waste it excessively on grid storage.
But they make antimatter randomly in particle acelerators, in atomic anounts. They can't just ramp up production. .... Magnetic Bottles don't hold it indefinitly. The antimatter particle will eventually leak through.
How does the ability to travel in outer space make the future better than the past? What will you do once you arrive at a location in space far from the Earth? We can already visually see massive objects millions of light years away, for no cost, so what is the point of trying to go there? Do you expect to find an amusement park when you get there?
By making almost limitless resources available humanity will be able to establish independent cities and colonies that will be able to express a variety of viewpoints and cultural norms allowing people with differing opinions somewhere to go. We will go to the Moon, which is only a few light seconds away, and then later Mars and Mercury. And when we get there we will build cities and humanity will expand and learn and develop technology not imagined by us.
@@terranspaceacademy Those are all good ideas. But I think the farthest Earth humans will go is to establish an outpost on the moon, and maybe on Mars. Maintaining any off-planet outpost would be extremely expensive, and the outposts would be completely dependent on Earth resources. We are certainly not capable of terraforming an entire planet. Dealing with Earth's dwindling resources and political conflicts should be our first priority as a civilization.
Special relativity....shows that velocity warps space-time. Correct calculation makes 10 light years a 1 year journey. Mathcad says so. Takes loads of energy.
@@terranspaceacademy the stationary observer sees the same contraction of the moving object. In reality the object is traveling at a higher velocity that either observer can measure because what we can see is a projection of 4-space on to 3-space.
Mass causing space to curve around an object is an explanation of why one mass is attracted to another. Newton made the first attraction of masses statement but couldn't figure out why. I am still a little skeptical of the curvature of space explanation of gravity, but it is all we have. It certainly appears Einstein was right about black holes, so I can kind of go with the curvature thing. That said, intuitively, I don't see us being capable of using that to come up with a practical warp drive. Too much mass/energy required to expand or contract space, especially both at the same time. Also, curving space and expanding or contracting it, are different concepts. A lot of imagining going on, whatever the case.
There's a pesky causality issue with the forward compression portion of the warp bubble. Sadly, it's probably going to be at least 100 or more years before we figure this out.
People say stuff like this all the time with no real basis for how they've arrived at such predictions... and then, only to be subsequently proven wrong. lol. I've never really understood why people bother trying to predict when or if something will ever become well enough understood or possible.
@@Djplax11 I much prefer optimism to "no, that wont work, im certain of it" or "it's probably gonna take forever to make this thing". Pessimists really have no place in science since theyre too busy focusing on what they believe cant be done, they completely overlook or fail to discover what CAN be done. 😂
When mass is going fast is there a show in the kinetic energy physicist when doing their calculations they show that mass at the speed of light is a larger a mass which is untrue are they showing is the energy potential of the mass moving at the speed of light
Star Trek was broadcast in 1966, only three years before humans landed on the moon in 1969 (you mentioned humans were "six years from walking on the moon")
The Alcubierre drive is science-fiction rewritten in the mathematical language of general relativity, postulating a single physics counterfactual that's a simple addition to those mathematics -- to build from it a general relativity construction which forms a decent representation of the science-fiction concept. It's an interesting piece of scientific art, and in its own way it illustrates what should be one's immediate reaction to the scale of the universe: there's no vehicle but imagination to explore it... which includes the fabrication of imaginary vehicles.

@@terranspaceacademy So how does the compression selectively avoid compressing the whole "scene" down - i.e. without compressing that one meter per second down to a micrometre per second. Think of how a black hole compresses everything inside of it - you can't compress space without compressing the whole "scene" including the objects. In this way distorting the "scene" does not change the dynamics within it. If you try to be clever about "where" you compress I think you will at some point run into my original argument.
@@terranspaceacademy The ship can't "pretend" to be disassociated from the field it creates around itself. That fact has immediate relevance for the boat and sail analogy.
The mass of Jupiter would be one thing. But what the warp drive requires, at least Alcubiere's version, is the mass of negative one Jupiter. That's something else entirely.
Ways for us to get to Proxima Centauri from cheapest to most expensive: - build a star and planets of Proxima Centauri in the Solar System (and this is the fastest one) - move Proxima Centauri to the Solar System (less materials to be used) - warp drive
The fastest way is lightsails powered by massive laser emitter array- possible, but a massive project. The second fastest is probably a warp drive (FTL or otherwise). It's only when you try "slow boat" that recreating another star system near ourselves can even _start_ to have a chance of being faster than the other choices.
Another classic utube creation by one of the platform's most enjoyable authors. Congratulations, and may you live long and prosper. 🙂
Thank you so much! And you also.
I'm still waiting for someone to demonstrate negative energy before I would take warp dive seriously
Would you rather see a real free energy the negative energy I can demonstrate free energy

The Casimir vacuum energy that was measured a decade ago is a form of negative energy...
@@terranspaceacademy I will have to look into that.
@@terranspaceacademynot the kind that we need for warp.
A number of thoughts concerning the ramifications of building an FTL warp drive...
1) If an FTL warp drive is possible, I am positive the human race will figure it out.
2) There's a non-zero chance that other intelligent species (if any) will begin to be concerned about the human race once we develop some kind of FTL travel capability.
3) Even with the ability to travel infinitely fast, it is impossible to completely explore an infinitely large universe.
regarding 3...you can't even search a measurable percentage of an infinitely large universe
@@sfurules True. Another realization: Whether the universe is infinite or not, either situation is profound.
Very true...
@@sfurules My dude. Any amount is a measurable amount. Just because we haven't figured out how small or large that number is doesn't mean that it can't be measured.
We measure stuff all the time, whether the universe is infinite or not.
Amazing and astonishing....my deepest respect for Alcubierre and Dr White...
Indeed. Brilliant scientists.
How does warp drive work over very short distances - interplanetary or less - or to the adjacent room? Can you go through a solid object?
You would not. A collision still hurts. It should work just as well over short distances.
Did videos of just become incredible with the way you present them, I know I keep saying this.. but it’s because it is true! I’ve been following everything science especially with space, cosmology, astronomy, etc. from as early as I possibly remember, too.. so well done!
Thank you so much!!
The Planck length is not as much a voxel size as it is blur radius; things bellow that length get blurry, but they don't snap to a grid. It's like reality bellow that scale is out of focus, or is jittery and suffers from motion blur.
Which probably means it is primarily a wave.
I think of it like the electron cloud. Something that doesn't exit at a point until interacted with.
planck lenght is the frequency of this universe
@@terranspaceacademy if electrons didn't exist till interactions, there would be no difference between elements.
Electrons exist in every configuration possible for each electron cloud of each element until we interact with.
When I was a teenager and our first landing on the moon was a few years away, this was utter, absolute fantasy. Clearly, such is no longer the case for warp drives, as is true with so much of what was science fantasy all those long decades ago. What we have accomplished in the meantime is, it appears, difficult to appreciate without some grasp of where we've come from. So while I think the concerns of those who say this will never happen deserve a hearing, I am absolutely convinced that one day, sooner than we think, warp drive will be a reality.
Indeed. It is awesome how much we have that foretold by the prophet Roddenberry :-)
With a few tweaks this gets interesting. We may not know for sure any time soon but this tech may already be in operation, shielded from the public. In 1993, Lockheed Skunkworks CEO, Ben Rich, told a class of aerospace grads at a grad ceremony "We have the ability to bring ET home" and was known to write out " *U*n- *F*unded *O*pportunities" and how they benefited the black aerospace industry greatly.
It is strange that so many knowledgeable people would drop such blatant hints if nothing is really there...
@@terranspaceacademy Any form of faster-than-light-(FTL) propulsion will cause a grandfather paradox. You can find articles on the Internet and UA-cam videos that talk about the causality disorder with all FTL drives. This is why I believe FTL travel will never be possible. If FTL travel is possible, a grandfather paradox can be unintentionally triggered, which means the immediate destruction of the entire universe. There are different gravitational fields in space and therefore time flows differently, and FTL travel between such objects of different masses will cause time paradoxes and the destruction of causality - (grandfather paradox). It's a pity you don't discuss this issue because it is the main problem with faster-than-light travel (FTL).

@@sanctuslex478Seen the alien drives 18x. It’s not a warp drive.
Im old enough to remember watching original, first run StarTrek back at my parent's home as a young teenager. I've been a devoted space creature ever since. I got to fly but not go into space.
But no, without FTL we are NOT going to seek out new worlds outside our solar system. New civilizations? Well, that would be nice, but I'm not sure they are remotely nearby. If FTL turns out to be impossible, we have this space only, or I guess virtual reality space. The latter sounds more likely at the moment. I certainly have followed Sonny at NASA, but he has made limited progress and I don't think NASA is totally onboard with him.
I like to think, nature found a way to put all these worlds out there and we will find a way to get there.
FTL travel is absolutely possible…
The only aspect separating our species from exploiting it to explore the cosmos is time.
Without some form of supraluminal transport we can't do it.
@@terranspaceacademyno, as I explained above it is possible to do it sub-light assuming habitable worlds aren't spread too far apart, eg 5 to 10 light years apart on average., and we can get to speeds above 10% of light speed (though the faster the better). Generational ships which could last a hundred years or so should be feasible whereas ones which travel at our current top speeds and take multiple thousands of years to make the trip are much less feasible. Such colonisation though would end up with human descended colonies throughout the galaxy given enough time but they would be physically pretty much isolated - there would be no centrally controlled galactic empire or federation. Though those in systems relatively close to each other would be able to communicate with each other by radio.
generational ships are thought by many to be unfeasible. And consider, TESS and Kepler have to date discovered roughly 5,000 exoplanets. Not 1 is earth-like. The "Rare Earth" solution to the Fermi Paradox shows that a large number of chance factors have made earth so remarkable for sustaining life. The nearest true earth like planet could be thousands of light years distant. Another advanced civilization could be tens of thousands of light years away. I haven't done the math, but it would seem that the USS Enterprise was able to travel at more than a thousand times the speed of light to go to the places it did during a "5 year mission". In fact today, the Star Trek series has just opted for "spores" that instantly deliver the ship to any spot in the galaxy.@@davidwebb4451
I too grew up watching the original. It's amazing how spot on was StarTrek in certain respects. Like that effect of the ship as it activated the warp drive, that's exactly how it would look like to an observer I think, or that they had to move out of a solar system to go to warp speeds, and they would use "impulse" speeds when nearby planets/stars or inside star systems for obvious reasons. I only got to fly in pc simulators. I don't think we'll see something of this sort in our lifetimes, I mean, I'd hope we would, I just kinda doubt it. Yes, there's so much to see, just like earth was massive to explore with horses, it got small with airplanes, in the same way, maybe with something like this, other star systems in our galaxy could become accessible.
Have you seen the work by Dr Erik Lentz? His paper improved on Alcubierre's work by removing the need for negative energy.
I must confess that I have not. I will do so.
We first need to figure out what makes gravity, is it a particle is it a wave or is it both? And can we amplify it like sound or electricity? you would need a lot less energy to make a warp drive feasible.
We just need to figure out how to make artificial gravity, then we're pretty much there.
Quantum gravity may be the last great question of physicis for us to answer.
WOW- Great Video! Thanks so much for this!
You are most welcome.
Very amazing work! I really enjoy these! Rn I’m an aerospace engineer student
Thank you so much!
technically, opening a hole is space and time and traveling through it is a "worm hole" and not a "warp drive". Warp drive is shrinking the space in front and expanding in back
But that's not what they are doing here. They are surfing a wave of expanding spacetime while falling into a zone of spacetime compression.
Awesome information and breakdown of space.
Glad you enjoyed it!
This is fascinating
Thank you
Top notch narration, top notch information and top notch video presentation 👏👏👏👏👏 BRAVO!!
Much appreciated!
Could we bend space in the same way warp drive works to make shuttles (like in Star Trek) that appear to be floating (from the perspective of those on the ground)?
Also 2nd question: what happens if 2 of these “warp fields” (bending of space time) collided?
Those are using antigravity... Which we don't have yet :-)
@@terranspaceacademy : A sub-FTL warp effect could be a route to real-world anti-grav.
just recently new simulations of it just came out alike a couple o so weeks ago and people and scientists irl all around the world are slowly warming up and starting to take the warp drive seriously even if FTL isn't possible STL warp drive would still be absolutely revolutionary I cannot tell you how excited I am
It doesn't violate any laws of physics so now it is just a matter of technological innovation.
How fascinating, This is what humanity should be working on because we all know we only have so much time.
Some are working hard on it...
The only problem if what you are suggesting is to focus a majority of time, resources, and funding to a warp drive is problematic because mathematically possible in reality there's a greater chance that a warp drive due to impractical processes and by a scientific limitation E=MC2 just isn't feasible.
Not to say that what can be learned wouldnt be valuable or useful. But to put most of our eggs into one basket one that is only possible mathematically would be a wager I wouldn't make.
Couldn't they make it smaller like for an unmanned probe the size of a smartphone maybe? Would that require less energy or does it not matter?
That would be the first goal.
Star Trek was the first colour TV programme I ever watched and have loved it all of my life. I am a die hard Star Trek fan… not a Trekkie!
I'm with you Martin!
Using two circular opposite rotating Casimir plates may produce negative & positive energy states at their closest point, which according to Hermann Bondi results in runaway motion towards the positive energy state. These plates can be nested to enhance said effect.
I would love to see it work.
I recall a YT video based on a paper that does what you describe but with negative energy only, but you say positive? I’m not questioning you I just got curious. The only paper I recall regarding positive energy is a rotating energy mass 10% of the Sun even with optimized emitter field, which is kind of unfeasable still.
There’s another paper regarding negative energy but utilized as Quantum Tunneling by lowering the wavefunction of the bubble, though the paper didn’t address particles tunneling (hawking radiation?) inside the bubble or even vacuum decay.

Why am I only getting 480p? 😢
I'm not sure... It was rendered in 4K. Upload problem maybe?
6:00 Little clarification here, its not a continuum if you are discussing Voxels. Least I am pretty sure that is the case and this simple fact is one of the issues with QM and GR being merged.
Hmmm. Interesting. Thank you.
As always double check and make sure that is the case but I am 98% sure Continum means just that, a constant space manifold with no breaks or non-interpolated regions. Its a bit nitpicky I know but just feel when talking about this sort of stuff its important as it may help understand the topic at hand and the issues GR poses to QM as one has discrete jumps and energy levels where as the other is a smooth transition from one to the other. Attempts to find discrete energy levels in gravity have all failed. That coupled with the fact QM smears particles across a probability yet gravity defines mass as a point are two of the more major issues with unifying them. It sounds like it would be easy on the surface but it is anything but.@@terranspaceacademy
I'm very envious of future generations, getting tech we never thought possible, tools to go more places and see farther.
It might not come to traveling to distant objects because of the time factor, but we can continue making better telescopes and computers and bring them to us.
They will live the life we dream.
I have some black hole concepts that might get us up to a fraction the speed of light but it works like a big gravity pump. One pulls a smaller one forwards then gets cut off do to grating closures of a dyson sphere, then it gets pulled backwards and like this, a piston like effect and the gravity waves are then shunted with particles that are roughly fractions the speed of light.
That sounds like a cool sci fi novel! Don't the Romulans use singularities in their systems?
@@terranspaceacademy Yes we could actually use this one if we could recreate something similiar to a soliton wave or if we could create a runaway black hole we could follow it with a really strong sail type system but it would have to be a very long sail to avoid damage from the black holes gravity. I then tried to create a sail that would basically convert the gravity into mechanical energy but its innefficient as far as I know.
Nice explanation.
Thank you!
How do you make spacetime thinner in front and thicker behind? Negative mass? If this is not possible, then no warp drive is possible.
Negative vacuum energy.
How can the universe still be expanding ftl though? How do we know it has the same "momentum" after 14 by, and if so, where is the energy coming from?
There is no limit on how fast spacetime can expand. Just on how fast something can travel through spacetime. The expansion may be like a gas in a vacuum. Powered by entropy.
We are working on it. The maths and synchronously are challenging though. You are quite correct about Planck time.
Thank you
How is it possible to know the equation is correct if you can't test it.
Mathematically consistent goes a long way but yes, experimental evidence is crucial. That is why Dr. White is trying to get positive results from a small experiment.
And as we develop those mathematical hypothesis, we may find some aspect of them that we _can_ test.
It's hard to remain positive for humanity when we have so little humanity to be positive about.
But we must find a way or all is lost.
turn off your TV and get off social media, humanity will start to seem a lot more positive after a while I promise

That would be great for attracting and repelling charged particles... Or do you mean positive and negative energy?
Trying to interpret the experiment? Are they basically trying to make a small gravity wave generator and then try to detect that gravity wave from the generator with a small gravity wave detector?
Kind of... they are seeing if it is possible to bend light by bending spacetime.
So many ideas about warp drive. Maybe we can do a thought experiment. Thought experiment of a warp drive equation. This is the equation. (positive infinite energy+ dyson sphere(magnifier)+ warp drive ship × radiation thermo (temperature))= warp drive engine. Let me explain. First the warp drive ship can only be flown by (AI) machine for now, because of radiation. Ok exotic matter, exotic negative matter for warp drive is a waste of time. It's a dream or nightmare. You must use what's in front of you, your environment. For example, in the Alaskan frontier, you might have to cut trees to build your home or use snow for drinking water, or if your an Alaskan eskimo, build your igloo home out of ice blocks or cut thur ice to fish to get food, etc,etc,etc. Again you must use what's in front of you, your environment. Ok, look at the equation again. Remember what i said, use what's in front of you. The sun is our positive infinite energy power source for warp drive travel, not exotic matter. You would put many giant solar deflector array dishes around the sun. Built by (AI) super computer. All the deflector dishes will redirect the sun energy into one highly focused concentrated energy beam and aim it to the dyson sphere magnifier. For example, how you can start a fire useing a magnifying glass with the sun. The magnifier dyson sphere, will be built by a (AI) scientist and engineer with infinite quantum processing speed. The (AI) artificial intelligence will figure out how to harness, how to collect, how to magnify that energy beam to the correct intensity. I think the (AI) won't use glass or mirrors. It will use something else . That beam will be aimed at the warp drive warp coils, and the ship will go into a spacetime tunnel. Now you might say, it's in the spacetime tunnel without a internal power source to maintain power to the warp coil static bubble shell. I know look at the equation again. Next is radiation thermo temperature. Remember, remember, we will use what's in front of us, our environment. We will use that radiation thermo temperature that energy, that friction, that heat, that radiation that surrounds the warp bubble to maintain the warp coil running. You see, you see, we don't need to bring an internal power source on the ship and no exotic matter required. We need to use that radiation thermo temperature and somehow convert use it's energy, into energy that the warp coils can use, built by artificial intelligence (AI). And the ship will travel without an internal power source in the spacetime tunnel. And you can stop the ship. Just block off that energy from the ship's warp coils. I guess useing some kind of force field built by (AI). And the ship will stop. Also, also i think, if we're lucky enough to have lived around a 2 yellow binary star system, it would be easier. We would have even more energy to Jumpstart the warp coils on the ship. More yellow stars equals more energy for the warp coils to work correctly. And Dr harold g sonny white talked about the ship being 10 meter diameter. But if you don't bring a internal power source and put the (AI) pilot in a tiny black box. You maybe can make the ship 2 meters in diameter or maybe 1.5 meters. smaller ship means less energy requirements. Maybe dr harold sonny white can run computer simulations useing 1 or 2 yellow stars, when he's not busy and post the video so i can see it.
Hmm... Let me think on it.
@@terranspaceacademyif you decide to run the computer simulation. Maybe use a giant yellow star 10 to 100 times the size of our sun, with the solar deflector array dishes around the sun. Maybe the dyson sphere magnifier can be smaller, because, we have all that energy. Or, if going to use a 2 yellow star binary put the deflector array dishes around the equator circumference of both yellow stars both. 2x the power for the dyson sphere magnifier. To Jumpstart the warp coils on the ship.
You had three channels! We had two. If we visited a big city there were four!
Now I'm confused!
JWST is in L5 if i recall correctly... while not massive in terms of "mass" it has massive capabilities!!!

Hah! :-)
What kind of interstellar/intergalactic pollution of the environment can be expected to leak from warp drives? How are quantities of negative energy expected to behave upon loss of containment?
No. You would just drop out of warp. There are theories that photons at the front of the ship will be shifted to extreme gamma rays that would be released on collapse of the bubble.
@@terranspaceacademy I asked no yes/no question there. My point is that the concentrations of negative mass required by the Alcubierre drive would be self-repulsing and thus necessitate confinement and have the potential to leak from it -- so that there'd be cause to ask what the impact on the cosmic environment would look like assuming negative mass pollution from alien drives over eons... analogous to the impact on Earth's atmosphere of our own combustion engines.
Seems like this would have to be assembled in space to avoid demolishing a section of earth or maybe the ship itself when the warp drive is activated.
That's correct. From lunar materials I hope so we can make it really big.

Warp drive would be great for sub light travel but I think you'd need to look time travel for its ability to change spacial position in a time vector or volume
You are probably right... Even with warp there may be limits.
Travelling faster than light means Travelling back in time.
There isn't a universal speed limit. You can travel at any speed, and the amount of energy you need to accelerate from 0 to 1 m/s is the same you need to accelerate from 1e20 to 1e20+1 m/s.
However, space is time. The time dimension changes at a rate of 1s every 300,000kms. This means that when you reach, say, proxima Centauri, you are 4.2 years in time away from home, so you need to add that to the time it took for you to get there (called "proper time"). So from a stationary observer, it appears that you traveled "slower than light".
A warp drive wouldn't automatically change that. If you could teleport to proxima in an instant (that would be traveling at the speed of light), proxima would still be 4.2 years away in time.
However, a warp drive may be used to bend time. Arriving any time before 4.2 years in proxima (no matter how much proper time you subjectively experience, your own trip within the warp bubble could take an instant or thousand years) means you effectively traveled back in time. Doing the round trip continuously would ultimately land you on the Earth before you first left.
That's not true... it is impossible to accelerate something past the speed of light. We've proved it in particle accelerators.

That is a very good point. I think it will be necessary to send a probe through that sends back data but it is an often ignored issue.
What you get if you would try to put a person inside of time dilation device? And what happens if we dont add too much of shielding? We dont actually destroy earth or matter but actually create a gravity wave. Interesting to think about.
A time dilation device would be a "stasis chamber"... it's also a time machine to the future.
Can you amplify the energy in the toroidal by creating synchronization waves or complimentary waves or decrease it with destructive or cancelation waves?
That is very interesting to think about...
@@terranspaceacademy i think of it like the pulsing of the Enterprise Ds warp core, each pulse reinforcing and amplifying the warp field.
I have a few ideas to make gravity drives, as this is something I always loved. A nuclear powered drive can be made and we already have the tech to make it happen, it only works in low gravity fields, the other is much more exotic to achieve and is definitely on a wish list and somewhat only if it's available as a resource locally in the solar system. That resource has not been found or confirmed, but may actually be found in the future, as some science facts say's it may very well be available. Hint is a Brown Star . I said that on 2023-11-12 how to curve space without energy.
Ask me if you are a NASA Scientist
You can curve space with any mass; matter or energy.
Spacetime is only conjoined when looked at from one perspective. Time is the measurement of movement, from subatomic quarks, to browning motion, and the larger permutations with mass.
If space can bend, causing any baryonic matter or electromagnetic waves to curve along their paths; then time can be bent too.
There is so much more to learn and not enough time to learn it.
While I agree that we should be multiplanetary, I'm not sure we are ready for it nor do we deserve it. Is it possible that we find a warp speed option? Yes, but I am sure the odds are not really in our favor.
It could be tomorrow or a thousand years from now.

Listen to the lecture by Dr. White. He explains it at length.

Even if you try to make one out of anti-matter you still end up with a positive number of anti-sheep. Not negative sheep. My objection isn't that the math doesn't work. It's that it relies on impossible things, therefor making the reality of the drive impossible.
Impossible is a far cry from plausible.
That's not exactly what a planck distance is. It is the smallest distance with meaningful distinction or measurable interaction. That doesn't mean things can't exist be happening smaller scales, but that they're effectively considered to the be same, and no meaningful difference in distance can be determined. It's an event horizon on the small scale. IE the horizon of perceivable/interacting contiguous events.
We just cannot know if there is anything below that level.
POWER has driven Eloi mad!

Where?! Wait! That was the hidden error that we include in every lesson for you edification! Yes! That's what it was :-)
People wanna tackle crossing the diatance but dont consider just trying to slow down time instead..
Some kind of temporary black hole generator/projector targeted in front of the vessle could slow down time and accelerate a vessel towards the black hole (gravity).. the trick would be how to generate and degenerate black holes and how to have enough power to do so... constantly reprojecting a new gravity well to fall into.. having a pull on effect much like electric motors work.
A black hole generator would be a tough thing to create but then so is negative vacuum energy. A kugelblitz maybe?
@@terranspaceacademy I'd be down for a kegel blitz lol
You can use Three Warp drive to provide negative gravity energy from each other they fly together in pattern
That would be awesome :-)
People shouldn’t just stand on a moving walkway at the airport, that’s not what is for. Stand right (if you have to) and walk left.
Sounds good... But in Australia they stand left and walk right. I know because I kept knocking people over doing it your way.
Lol, I never considered that either … Thank you!! Lol
Stand on the left and right, and walk down the center in the opposite direction of motion.
You will get nowhere fast.
Oh wait, I'm confusing treadmill and moving walkway.
For some reason people don't know about the 1 realistic method for interstellar travel. If a ship leaves our solar system traveling at a constant 1g acceleration rate it would get to Alpha Centauri in 3.6 years (7.3 years would pass on Earth) and this includes turning the ship around halfway to decelerate. It would achieve about 95% light speed after about 1 year. A 10 ton ship would require a mere 10 tons of continuous thrust.
This is by far the fastest way we can get to other worlds and the ship would have gravity the whole way. All that is needed for this is a true fission rocket that consumes uranium or plutonium only.
They are both jittery atoms that are on the verge of fissioning all by themselves. There should be a way to get them to fission in a linear fashion. What's needed is a controlled, time released nuclear explosion.
In an atomic bomb fission occurs when neutrons hit uranium or plutonium nuclei. This is because they will not tolerate an increase in mass. Due to the equivalence of mass and energy the same should be true if you infuse them with energy.
I made a video which illustrates 3 new true fission rocket concepts, "Best method for interstellar travel".
With the constant 1g acceleration method a ship can span the entire diameter of our galaxy in 24 ship/ 113,000 Earth years.
There is no way solved to accelerate continuously at one g. And atomic bombs don't come close. Though Orion is cool and Dyson was a genius.
@@terranspaceacademy A true fission rocket should not be too complicated. All proposed fission rocket concepts incorporate hydrogen or xenon in their process. This automatically makes them unsuitable for interstellar travel because you can't bring thousands of tons of that with you.
@@terranspaceacademyThe fuel requirements to continuously accelerate for long periods at 1g, eg a year or more, and then decelerate to get to your destination are gigantic. Fission won't be good enough, you might get closer with fusion but you would probably require total fuel conversion ie anti-matter.
People should consider this: at a particle accelerator, we propel an electron (for example) to extremely close to the speed of light, and nothing spooky happens. We know of no way to make anything go any faster. If we can’t make a single electron do it, there’s no way to make moles and moles of electrons do it.
Yes... something spooky does happen. Time slows for that particle and it gains mass.
@@terranspaceacademy everyone already knows that lol. And those effects apply to everything external (from the particle’s point of view). Nothing changes in the rest frame of the particle.
But thanks for making this content!!
You are most welcome.
Hold on, if we can accelerate one electron to near the speed of light, then there _is something_ we can use to accelerate several moles of electrons to the speed of light.
It is the same thing that the Ancient Egyptians used to build the Great Pyramids, despite them seeming to not have the technology to do so, today;
Patience. 💡
Didn't Star Trek come out in 1966? Three years before we got to the Moon..
I lived in a semi rural area in the '70s, and we got the three network stations, two independent stations ( that aired Star Trek) and PBS ( that had Nova and Dr. Who). In some of Alan Dean Foster's science fiction tales, the FTL ships had the engine out front, and the ship fell towards the warp, without ever getting to it..
Star Trek predicted...or influenced....reality more than once. The old flip phone had to have been inspired by the communicator, and there is transparent aluminum....( Alon).
Great video, by the way...
Star Trek came out (1963) six years before we went (1969) and ended (1969) three years before we left (1972)
@@terranspaceacademy I had it in mind Star Trek came out in '66 and ended in '69...
I started watching it in first grade ( 1968)..
Star Trek was first broadcast in 1966 but the two pilots were filmed in 64 and 65. In the third feature film in 1984 the Enterprise is said to be 20 years old, which was true of the original filming model as seen in ‘The Cage’.
Roddenberry first started pitching the idea of Star Trek earlier than either pilot was developed, so perhaps it can be said that it started in 63.
You are most kind! When did the pilot with Pike go out?
@@terranspaceacademy it wasn’t officially broadcast until the late 80s, but of course most of it aired as parts of The Menagerie in 1966.
Actually the plank limit is just the smallest that can be MEASURED, not necessarily the smallest that can exist. If all you have to measure with is an inch, then the most accurate you can measure is an inch anything smaller is only an estimate.
And no, the shifting gravity is one of the slowest ways to travel - but would use the most minimal amount of fuel which is how the small asteroids enter an L4/L5 position. they will also only stay there for about 400 years, then move out of those relatively stable areas.
It's tough to say what might exist below what can be measured in any way. The gravity lanes aren't the propulsion system. They are the highway. Amplifying our speed and creating a true highway/shortcut.
The Miguel Alcubierre papers where written hundreds of year before the Miguel Alcubierre you explain in the video lived. I literally wrote those papers hundreds of years prior, having already built a Warp Drive Engine. By the way, I was Albert Einstein, and the writer of the Miguel Alcubierre papers
No my friend. You did and are not. And a little Haldol would make that clear to you. Best of luck.
@@terranspaceacademy Keep believing a guy that believes a Warp Drive Engine would produce a lethal dose of radiation, wrote those papers.... and not Albert Einstein.
@@terranspaceacademy you are no friend of mine.
@@terranspaceacademy How would you even have a clue what Einstein taught, because Einstein didn't teach All I did as Einstein was write a couple of papers, you are making guesses about antimatter. First off, seccondly my Warp Drive Engine is in the center of Pluto
@@terranspaceacademy There is a formula for creating Warp Speed, but no one has done it yet is what you are saying, and yet Star Trek covered warp speed before Miguel Alcubierre was even born...
I hope I see this in my lifetime. One gotcha is the shifting of electromagnetic waves to higher and higher energies. It would fry organics. I am curious about the actual physical mechanism that is the "working" part of this drive. Does anybody have any idea what it would be? Some kind of coil or capacitor? Or is it all theoretical and they haven't worked that part out yet?
Edit. Maybe it won't fry people. The lecture makes it sound like your acceleration and velocity would be zero. Interesting.
I hope so too... Indeed, hypervelocity without inertial changes... UFOs!
There unfortunately would still be frequency shift, as you'd essentially be sitting inside a standing wave. However, by the time that the technology for this sort of thing gets worked out, we'd be long past our current "orbital scarcity" state, so I'd worry more about micrometeors & such.
Damn good video compared to others!
Thank you so much!
What about subspace communication??
We will cover that next week :-)
6 years, from walking on the moon to 6 years from walking on the moon again, 2 years as of this comment. On the surface it looks like not a lot of progress. But that's far from the case, starting with the cost of getting to the moon has dropped from an average $50 billion, in today dollars, per trip decades ago to an estimated $10 billion in today's dollars in a few short years.
And while the Apollo missions could reach equatorial regions and some higher lunar latitude on the near side of moon, the Artemis missions will use near rectilinear orbits that can reach anyware on the moon for much less cost for 21 days with the lunar gateway providing a permanent base for power, life support and communications relay for missions to the back side of the moon and polar regions. The Artemis missions will be doing far more than the Apollo missions for much less cost.
Maybe we might bemone that it's taken us this long to go back, but we shouldn't sell Artemis short. What's taken us so long has more to do with national want and will than technology.
I personally believe we should work to a solar pannel manufacturing base on the moon and a lunar spin launch platform to launch them to Earth geosynchronous orbit and beam beam power 24/7 to locations on earth, to cover peeks in demand and lulls in supply.
Just to make a point, Spinlaunch current suborbial platform on earth if placed on the moon could launch with a pannels with a lunar escape velocity. If we prioritize this, we could have this up and running in 20-30 years so that Over the next 50 years we can reduce fossil fuel use virtually eliminate it in 100 years.
Space based solar power beaming to earth would allow us to use lithium for transportation energy storage and not waste it excessively on grid storage.
Hopefully we will see it soon.
But they make antimatter randomly in particle acelerators, in atomic anounts. They can't just ramp up production. .... Magnetic Bottles don't hold it indefinitly. The antimatter particle will eventually leak through.
They don't need antimatter... They need negative mass. The only hope for that is negative vacuum energy.
How does the ability to travel in outer space make the future better than the past? What will you do once you arrive at a location in space far from the Earth? We can already visually see massive objects millions of light years away, for no cost, so what is the point of trying to go there? Do you expect to find an amusement park when you get there?
By making almost limitless resources available humanity will be able to establish independent cities and colonies that will be able to express a variety of viewpoints and cultural norms allowing people with differing opinions somewhere to go. We will go to the Moon, which is only a few light seconds away, and then later Mars and Mercury. And when we get there we will build cities and humanity will expand and learn and develop technology not imagined by us.
@@terranspaceacademy Those are all good ideas. But I think the farthest Earth humans will go is to establish an outpost on the moon, and maybe on Mars. Maintaining any off-planet outpost would be extremely expensive, and the outposts would be completely dependent on Earth resources. We are certainly not capable of terraforming an entire planet. Dealing with Earth's dwindling resources and political conflicts should be our first priority as a civilization.
Special relativity....shows that velocity warps space-time. Correct calculation makes 10 light years a 1 year journey. Mathcad says so. Takes loads of energy.
Well it compresses space time for the moving object but is still limited to c. Warping spacetime is not limited by c.
@@terranspaceacademy the stationary observer sees the same contraction of the moving object. In reality the object is traveling at a higher velocity that either observer can measure because what we can see is a projection of 4-space on to 3-space.
Mass causing space to curve around an object is an explanation of why one mass is attracted to another. Newton made the first attraction of masses statement but couldn't figure out why. I am still a little skeptical of the curvature of space explanation of gravity, but it is all we have. It certainly appears Einstein was right about black holes, so I can kind of go with the curvature thing. That said, intuitively, I don't see us being capable of using that to come up with a practical warp drive. Too much mass/energy required to expand or contract space, especially both at the same time. Also, curving space and expanding or contracting it, are different concepts. A lot of imagining going on, whatever the case.
Imagine us compressing just one nanometer to a picometer in front of our ship... and traveling 1,000x faster.
There's a pesky causality issue with the forward compression portion of the warp bubble. Sadly, it's probably going to be at least 100 or more years before we figure this out.
I call BS, I work in propulsion give us 30🫡
I agree with 30 to 50 but it could be even sooner... quantum gravity would probably solve it for us.
People say stuff like this all the time with no real basis for how they've arrived at such predictions... and then, only to be subsequently proven wrong. lol. I've never really understood why people bother trying to predict when or if something will ever become well enough understood or possible.
@@Corteum no valid I’m just optimistic and hopeful
@@Djplax11 I much prefer optimism to "no, that wont work, im certain of it" or "it's probably gonna take forever to make this thing". Pessimists really have no place in science since theyre too busy focusing on what they believe cant be done, they completely overlook or fail to discover what CAN be done. 😂
Nice
Thank you!
When mass is going fast is there a show in the kinetic energy physicist when doing their calculations they show that mass at the speed of light is a larger a mass which is untrue are they showing is the energy potential of the mass moving at the speed of light
But it is true... It has been proven in particle accelerators for decades.
Star Trek was broadcast in 1966, only three years before humans landed on the moon in 1969 (you mentioned humans were "six years from walking on the moon")
You are correct.
The Alcubierre drive is science-fiction rewritten in the mathematical language of general relativity, postulating a single physics counterfactual that's a simple addition to those mathematics -- to build from it a general relativity construction which forms a decent representation of the science-fiction concept. It's an interesting piece of scientific art, and in its own way it illustrates what should be one's immediate reaction to the scale of the universe: there's no vehicle but imagination to explore it... which includes the fabrication of imaginary vehicles.
Tell that to Einstein my friend :-) He thought of it.
Depends on what you call 'it'.
Hi I'm Ariful Islam leeton im software engineer and members of the international organization who and development international Space Starship and development ISS
Hello Ariful. I am not familiar with an International Space Starship. Could you bring me up to date please?
What does "ort time" mean?
Oops saw earlier slide (York Time).
Ort time is when you ort to get up as opposed to when you actually do :-)
Wouldn't this be a bit like sitting in a boat and blowing wind into the sail? I.e. even if the science mostly checks out it simply won't work...
It should... going one meter per second then compressing that meter down to a micrometer gets you a million meters per second down the road...
@@terranspaceacademy So how does the compression selectively avoid compressing the whole "scene" down - i.e. without compressing that one meter per second down to a micrometre per second. Think of how a black hole compresses everything inside of it - you can't compress space without compressing the whole "scene" including the objects. In this way distorting the "scene" does not change the dynamics within it. If you try to be clever about "where" you compress I think you will at some point run into my original argument.
@@terranspaceacademy The ship can't "pretend" to be disassociated from the field it creates around itself. That fact has immediate relevance for the boat and sail analogy.
The mass of Jupiter would be one thing. But what the warp drive requires, at least Alcubiere's version, is the mass of negative one Jupiter. That's something else entirely.
Indeed.
Ways for us to get to Proxima Centauri from cheapest to most expensive:
- build a star and planets of Proxima Centauri in the Solar System (and this is the fastest one)
- move Proxima Centauri to the Solar System (less materials to be used)
- warp drive
Nope...
The fastest way is lightsails powered by massive laser emitter array- possible, but a massive project. The second fastest is probably a warp drive (FTL or otherwise). It's only when you try "slow boat" that recreating another star system near ourselves can even _start_ to have a chance of being faster than the other choices.
