[@johnbennett1465]

I was interested to hear that antimatter can be collected. That is good. Unfortunately he overlooks one problem. He complains about the safety of fission reactors, but ignores the worse safety problem with antimatter. If you have a containment failure, you don't have to worry about radiation, because you and your space ship rapidly become an expanding ball of plasma. All that beautiful energy you were going to use to travel will be released at the smallest containment failure. The explosion from the initial contact between matter and antimatter will destroy the containment field guaranteeing total failure.

[@oO0Xenos0Oo]

To be fair, a failure of the fuel containment system is a death sentence in any case when it comes to space travel. Even with regular rocket fuel you get stranded in the middle of nowhere, because you will overshoot your target without enough fuel for backburning or your ships just blows up.

[@anonanonderson7065]

I like Johns point, but let's not forget that we can't make an omelette without a few cracked eggs. If humanity is to reach for the stars, we must expect a few failures on the way. Surely, we can find a way to make this even safer, by making a ship that can detach itself from the engine and in that way, ensure survive ability for the crew. No one said it would be easy, but if we want to get anywhere we must do so trough trial and error. Human loss, is of course sad, but it haven't stopped us from still trying.

Honestly fusion and antimatter are on even playing fields for space travel. Both require using vast amounts of power just to run, both produce ludicrous amounts of radiation, and both would require exotic cooling for them. The difference is on a fusion reactor you can turn it off, for antimatter, even when it isn't firing, you still have to use electricity to not annihilate all your fuel. So in this regard, I'd actually say fusion reactors make vastly more sense than antimatter as it also still has the same issue with getting equal energy put in as gotten out (both require magnetic confinement for the fuel). Antimatter is even worse if gotten from particle accelerators making it more just a battery.

Good point. antimatter, except for the very small amount that can be found in orbit, is a battery and not an energy source. You will need to manufacture it, while you can find deuterium as a fuel for fusion anywhere in the universe. Very large anti mater manufacturing plants are a possibility, but they would be very expensive, possibly negating the gins. and for the moment the fabrication of anti-matter is very inefficient, with an efficiency that is 1% or less. So your plants would have to be 100 times larger than what gets stored in the anti matter. not very cost effective.

I agree with Michio Kaku that antimatter propulsion will never happen. For some reason people dont know about the one realistic method. If a ship travels at a constant 1g acceleration rate it would get to Alpha Centauri in 3.6 ship/7.3 Earth years (and that includes turning the ship around half way and decelerating). The ship would achieve about .95 light speed after about 1 year. A 10 ton ship would need a mere 10 tons of continuous thrust. Not only is this by far the fastest way we can get to other worlds but the ship would have gravity the whole way which will allow farming. All thats needed for this is a fission rocket that can put out thrust for long periods and does not consume hydrogen or xenon (you cant bring 500 tons of that with you). 1 kg of uranium has the same energy as 120,000 tons of coal and plutonium has a lot more than that. A 10 ton ship would use less than 1 pound of uranium to get to the Centauri system. Uranium and plutonium are jittery atoms, there should be a way to get them to fission in a linear fashion, see "best method for interstellar travel". A fission rocket should be simpler than a chemical rocket. It will be the new safest way to travel. Due to relativistic effects the ship will only have a weak interaction with regular mass during the high velocity portion of the trip. The front of the ship should be an asteroid or at least armor plate. The ship would be at maximum velocity in the voids between systems were the chances of significant mass being in the flight path would be astronomically low. It would also need a powerful radar (RF emissions will travel at light speed regardless of the ships velocity). Interstellar radiation is not a problem either, a couple feet of asteroid dirt (and perhaps graphite and/or lead) will keep it out. With this method a ship can span the entire diameter of our galaxy in 24 ship/113,000 Earth years. Systems with stars similar to the sun can be reached in under 10 years. The human race can be interstellar in our generation.

Could also have a magnetic confinement afterburner to fuze the leftover deuterium after the antiprotium-hydrogen heats it up. Or if in a toroidal form, could use antiprotons to turn the alpha particles in helium plasma into tritions, making a fusion equivalent of a breeder reactor. Alternatively, lithium isotope ions can decay into tritions and helium. Also since the hydrogen and superconductors required for the confinement fields need to be near 2kelvins, muon catalyzed fusion could be utilized for extra electrical energy, along with the more traditional photovoltaics and such. Liquid metalic hydrogen could serve as a coolant, a fuel, and a ferrofluid rotating around the confinement field, generating its own magnetic field in the process. The protium isotope is predicted to be superfluid and superconductor around that temperature as well, further increasing efficiency in its metalic form. If liquid metalic hydrogen can be used, then it could also generate more electrical power as it could form a flow battery prior to the antihydrogen-hydrogen reaction, while also storing energy in its magnetic fields.

Reaching high speeds quickly is great and all, but I can't help but bring up a few issues. 1) a high top speed is one thing, but one must also consider the acceleration necessary to reach those speeds in a timely fashion. Most untrained humans can only take something like 6 to 7 Gs of sustained force without running into health issues, so that rules out the sorts of accelerations that would be needed to reach Mars in a matter of hours or Alpha Centauri in only a couple years. You would have to go slower because of human biology. 2) how would you slow back down again? almost all terrestrial aircraft use wind resistance to slow down, but you can't do that in space. You'd have to have a craft equipped with forward brake thrusters, which is fine, the only problem being that deceleration takes time just like acceleration. So that would be another barrier on the average speed of a mission due to human biology, not technological capability.

[@theobserver9131]

He did address the limits of human tolerance for G forces, and how you decelerate is by turning the craft around and facing the other way. Accelerate for half the trip, turn around and decelerate for the other half of the trip. All at one G when transporting human passengers.

Honestly think this was one of his least researched videos yet. His main comparisons being fusion and fission both being completely improperly explained in the process. Enriched reactor grade uranium is not weapons grade uranium, in fact it's as far from weapons grade as could be. Antimatter also has the same issues as fusion today. Both have the issue with getting more energy out than what we put in. Antimatter needs to be held and manipulated with magnetic fields which is the same issue we have with fusion in that it means you need energy to get the energy we want. The reason fusion reactors right now are so big is that product scale raises the ability to make surplus energy and it gives more space for more powerful magnets. We can also use compressed fusion like general fusion for smaller scales though and we now have developed magnets 40 times stronger than even what ITER was designed with in mind. So making a much smaller reactor is possible now and should get better with time. But the main issue with antimatter is cost to get it. Particle accelerators are far too costly to get it and sending pods into space just to collect it is incredibly wasteful. The project needs to be cost effective to conventional rockets, being faster doesn't make it more profitable. Maglevs are vastly faster than normal rail, but China, the nation with the most maglevs has had struggles getting people to take it as normal rail is about 4 times cheaper. This would only make sense if we were actually considering going interstellar.

turn down the power levels, you can dial the amat flow down as much as you want. gives less thrust but can essentially be dialed down until you can use a wet paper bag as the nozzle

[@Sapphier4Dav]

That was the best switchover to Brilliant advertisment i have seen so far :D

[@apex.graphics]

The thing is if you can collect antimatter... why make a propulsion/combustion style engine? By the time we have the technology to capture it, and utilize it a exotic propulsion system could probably be developed. I feel like this could never work with the magnetic nozzle in space - If antimatter reacts with anything passing through that nozzle it would blow the spaceship apart. Not to mention travelling at those velocities even with a physical shield. If the ship were to hit a object at those velocities it would destroy the entire ship. At this point the ship needs a gravity/magnetic shield so you might as well develop a gravity propulsion system with anti matter being the fuel. Combustion engines are at an end at this point in history. Nuclear is probably the most optimal/logical choice if it can be clean enough.

[@theviolenceenjoyer]

Thanks bro. how long did it take for you to get a degree in physics again? 😭

[@noalear]

Oh, an exotic propulsion system. I never even thought about that.

[@apex.graphics]

@@theviolenceenjoyer I wish I did at times... Sorry, I just enjoy thinking/debating/constructively arguing about this stuff. I do a lot of engineering animations, and I like challenging engineering and asking questions. Helps me understand a product better when animating.

[@corynrobinson]

Dude, your editing is getting amazing!

[@lordzarzinekh2591]

Someone please forward this to Elon Musk please

[@richardkennedy6203]

I’m totally geeking in this -nice production!

[@davidsirmons]

Cool to finally see the face behind the fantastic science. When we learn how to change quark vibration directions/frequencies we'll be able to manufacture antimatter.

[@nightlightabcd]

Love your enthusiasm and optimism!

[@mikethespike056]

I literally cannot believe how high quality your videos are.

[@Mrcometo]

9:00 Medical MRI are currently over 10T and they does not weight thousands tonne.

[@Sweenus987]

8:25 I know it's a joke but for those who don't know, we already have fusion figured out, net positive fusion on the other hand is where the issue is at

[@bobboland8505]

The Intro was slick! nice job, keep it up

[@MrGiovannisassano]

5:08 the Pennington trap needs an antimatter injector that way you're not losing a lot of fuel you're gaining a lot. As to ramp up its production in collection.

[@bobhackmeister4747]

I love the new format! Waiting for more awsome content!

[@meinkamph5327]

Faster then light is possible. We just need to break the light barrier. It should be easier then though. We need to change how we interact with the universe. Light is energy moving in every direction, it has mass, the universe is a fluid. How do we work around this?

[@texasslingleadsomtingwong8751]

I need you to animate plumbing issues for my customers. The quality of your video is incredible.

[@jellydee123]

loving the editing on this video

[@Anarchy_420]

The haul of the ship should be coated if not made of a mix of Carbon Nanotubes, Tungsten Tetraboride, and Diamond!

[@Anarchy_420]

Traveling at those speeds, a ship not durable enough could be easily destroyed!

[@jlco]

Wouldn't the magnetic containment system be just as big for antimatter as it would be for fusion?

[@m.t-thoughts8919]

11:20 Those g forces are more usefull then for more autonomous missions or better drone like cargo ships which are getting loaded and unloading by other drones.

[@rocketmentor]

Snowball antimatter seems like a lot simpler and safer than a conventional Penning trap AM with the near absolute zero of space keeping the snowball cold is assured, just get the flow of antimatter to the reaction chamber safe, keep the distance between the snowball storage and chamber short as practical. The AM capture method finally give hope to AM propulsion with 1g acceleration like in the movie Passengers. Thank you for the video, Ken

[@deleted_account-u3w]

Antimatter generates a huge amount of energy, it's also very unstable, which isn’t very good if you’re going to be storing it in large amounts. Additionally, the antimatter can easily overload the reaction chamber and lead to a rapid unscheduled disassembly.

[@ion_force]

This is one of the first "space travel tech" videos that I've seen which doesn't repeat old news about the Alcubierre warp field or other topics that have been discussed to death.

[@mayday6880]

I think two-Laser Proton-Boron aneutronic fusion has the potential for a propulsion system (Ion beam) They use newest picosecond lasers in petawatt power range. No radiation problems (no neutrons from primary reaction) and no radioactive waste.

[@yannickleroy7419]

Incredible production quality

[@TianarTruegard]

The problem of storing hydrogen (not to mention the antimatter) is a bit glossed over. Liquid hydrogen tends to boil off, there goes half your fuel. The antimatter would require a constant and significant and reliable power source to keep it contained (nuclear or RTG, possibly solar/battery). Can't be used in a near Earth orbit, the gamma ray exhaust would kind of be an issue. It does have potential if the issues can be solved.

[@marinarepan5578]

Interesting, thank you. Such solutions are vital for fast spaceflight, so we need to make and use them. I'm glad to find this channel.

[@EspressoBreve]

what about slowing down? 1G acceleration towards destination, but what about deceleration? Would you reverse engines midway or 3/4 of the way and increase to 1.3G+?

[@Unmannedair]

The destruction of antimatter releases a nearly pure burst of gamma rays. Harnessing that and turning it into a form of propulsion is currently nearly impossible. It's so energetic that it can cause nuclear reactions in stable nuclei. That means any engine that gets built would slowly eat itself. And by slowly I mean pretty quickly.

[@ristube3319]

9:44 Uh it’s called a Warp Drive engine. I’ve seen it used on a documentary called Star Trek.

[@SuperTrex1999]

What's the muisc/song between 9:35 and 11:05?!

[@deniswilloughby2662]

Thanks for a great update, looking forward to Tuesdays video...👌

[@andreapalmas6428]

BEST INTRO EVER!!! That gave me chills...

[@nobodyinparticular968]

i see alot of people talking about safety concerns with the ship exploding due to a containment failure or something, but its important to recognize that a containment failure wont just happen at random for no reason, obviously the technologies to store a pellet of antimatter would be very complex, but it really boils down to some exceptionally big magnets, and probably some sort of cryogenic refrigeration system attached to them or something, which, complicated as it would be, would be relatively simple in the grand scheme of things, making sure this big magnet doesnt turn off would be as easy as testing it a few times before launch and having some backup generators on board incase one stops working, infact, this machine would probably fail less often then rocket thrusters, plus, if your rocket thruster melts, or if your antimatter containment cell explodes, they are both equally as catastrophic, as in they gaurentee the crews death, the only difference is what happens when one explodes on the ground, since the explosion for the antimatter thruster is so much bigger, but that can also be lessened by just increasing the evacuation radius during launches, in reality an antimatter thruster is, in terms of danger, the ecxact same as an ordinary thruster i, think, that, needs, more, commas,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

[@sheesbinshahid7082]

Your video editor is really good.

[@alonenjersey]

When i was in High School ('79-'82), the films we sat through were no where near as interesting as your latest production! Two thumbs up!

[@onerimeuse]

The intro was like watching the intro of the expanse. Well done.

[@angelstrong792]

Excellent futurenow technology, keep it up!

[@GerardPinzone]

What's the music from 4:29 to 6:04?

[@rickpontificates3406]

We always hear about "Warping space". I have this vision of humanity learning what the fabric of spacetime is and then figuring out how to GO AROUND IT, like finding a hidden hallway in a mansion and BYPASSING the rooms. It's generally accepted that spacetime itself is moving into the void faster than light. Maybe we can too, if we go around space?

[@huffingtonpost6777]

VERY GOOD production This was a great video

[@sssssnake222]

When we get to the star that we're going to, can't we just deploy a solar sail to decelerate us? The bigger the sail, the bigger the push right? Closer you get to the Sun the more push? Can we make like a air break with solar sails?

[@RealAeliux]

The animation in this video is literally better than any movie i’ve ever seen

[@EIndependent_Life]

If we can use a Laser beam to compress matter and a high energy particle accelerator for neutron spallation, why not combining the technologies to detonate thick ceramic coated spheres of Plutonium in space?
