I would use fission; we already know how to do controlled fission. NASA has tested fission rockets on the ground. Needs more fuel, but that's "merely an engineering issue". 🙂 There was a paper for JPL in 1962, "feasibility of interstellar travel" where the guy did the math and said you should be able to get to 60% the speed of light with fission, if you don't use the rocket to slow down. (if you DO use the same rocket to slow down, you're looking at 40% the speed of light. For a two way trip, 20%. But the estimates change if you don't need to use the propulsion rocket to slow down.)
You can actually use a magnetic sail to slow down; use the nuclear reactor to generate a huge magnetic field, and this will repel the solar wind from the target star, slowing you down without having to expend fuel. 🙂
Speeding through space above 0.2c means relativistic collisions with space dust.
Ответитьyea, alpha centurai is only 27 trillion miles, or 40 trillion km away, walk in the park
ОтветитьWouldn’t it be easier to take care of our own planet?
ОтветитьThere is no travel needed.
ОтветитьAntimatter and babies.
ОтветитьFormation of ugly babies
ОтветитьFormation of intrastellar space with less observation
ОтветитьIf this was possible then where are all the aliens!!!? Its not possible just like time travel.
ОтветитьI'm most excited about the extinction option so our stupid ape species doesn't pollute the galaxy.
ОтветитьWhy can't they use the slingshot effect to slow down at the other end? As long as there are enough planets etc it might be doable?
ОтветитьWith any of these proposed, and supposed methods there are many details that don't get addressed in these videos. As others have stated, hitting something, even microscopic, at these speeds would be catastrophic. With the proposed "warp drive", where, or from what distance from the ship, does the contraction of space-time in front and expansion behind the ship begin? There is space inside the ship and space inside the passengers, also. What about objects behind and in front of the ship, being in the expanded or contracted space? Could those objects be driven through the ship, from behind, or from in front of it, when the warping is started. Another question is; how far, in front of, or behind, is space going to be warped, and what would be the effect on exterior objects along the lines of the warping? This concept is a bit far out for this old plow boy to wrap his head around, if I think much about it.
ОтветитьGet over it were all stuck here
ОтветитьNot happening in our lifetimes and we'll cook the Earth in the meantime.
ОтветитьIs the blackhole drive converting energy to mass ? But to power those lasers, you would still need a source of energy. Doesn't that just move the problem of where to get that energy? Or is the blackhole created at the start of the journey as a form of energy storage? But doesn't such a blackhole evaporate very quickly ? Moreover you can't turn it off, which is rather bothersome.
ОтветитьMaybe we can drive with bicycles from planet to planet if Matter is formed correctly.
ОтветитьYou can drive with a car actually.
ОтветитьHow ironic would it be if our world ended with us all blasting each other off into space in hopes to find another planet like sperm searching for am egg
ОтветитьIf we travel that fast, how de we make sure we don't hit anything on the way? Planets, meteors, etc...
Ответитьsomeone recommended me this chanel, it's so interesting 🙂
Ответитьwell you space cadets better start saving your pennies to pay for your stupid dreams....or do you expect to receive slaves like the pharaohs did? perhaps we just tar and feather all those gallant schemers and dreamers of stupid sht
ОтветитьYou don't mention the fact that only a fraction of humanity could be saved, because we only have classical rockets to lift us out of Earth's orbit, and 7 billion people is way too much weight for this
ОтветитьComplete nonsense video
ОтветитьLet’s get going with this
ОтветитьTrisolaris be like 😂😅
Ответитьand what if planet in alpha centauri is uninhabitable?
ОтветитьAnti-matter drive is a very exciting possibility! We just need to figure out how to mass produce anti-matter. The potential it has as an energy source is amazing. 0.8c! Can you even believe it? But with anti-matter still being so hard to create, it might take some time, and until then, fusion should work ok.
Ответить3.3 years from the astronaurs perspective, but what about on Earth? How long?
ОтветитьIf I was a billionaire and had to bet my fortune on one of these it would be antimatter.
Ответитьkegel blitz
ОтветитьWe've now taken hundreds of thousands ultra high resolution photos of space, in pretty much every direction there is. The answer to this is most likely to be as boring as the ending of the movie Ad Astra. There is no magic solution to our sci-fi fantasies. They are fictional. If space bending and "interdimensional interaction" was a thing, we'd seen some kind of natural occurrence of that by now.
I am not saying we're alone in space. Obviously not. I am just saying, space is so unimaginably vast that we will always struggle to reach any other interstellar civilisation. Sci-fi alternatives like "generation ships" will probably be the only way we'd "get across". A one-way ticket that'll take generations to complete.
The powers that be will not allow human interstellar travel until humanity learns peace with itself.
ОтветитьThere is also the option of chain fusion. From protium, to helium, to carbon fusion, extract fusion energy to the top.
Also far fetched.
More options, reverse fuel. Send through a Canon a fuel path. Try to create the concept of the Bussard engine of collected the fuel during the flight, just if it doesn't exist that fuel, you launch it before sending the rocket. Require a level of precision that it's probably impossible, but it can be explored.
Also, for previous colonized stars, laser or charged particles beams for solar or magnetic sails could also work for deceleration.
I assume that giant space laser would be build by an Israeli company?
Yes, I'm looking at *you*, Marjorie Traitor Green.
And I'm rolling my eyes very loudly.
The durability of the materials that make up the spacecraft for voyages to other stars worries me the most. Regardless of the engine that is used for the trip. Break down or explode halfway on the trip. I mean cosmic rays do make materials brittle.
ОтветитьAin't gonna happen. We'll go extinct before it could happen.
ОтветитьOh! This was seven years ago- that explains why he quoted Muskrat in a scientific context rather than a comedic one
ОтветитьThe future of humans is on earth, not "in the stars". The stars are far too hot.
ОтветитьMate you're not 15 anymore. Get a haircut and some decent clothes.
ОтветитьWho's going to build this craft? NASA, who is currently 20 years into building their latest creation...an off-the-shelf Space Shuttle with the Shuttle part omitted? 😂
ОтветитьHe needed a beard to be complete.
