![]() Mind you, all those calculations were done assuming you will burn at 1g until half the distance, and then burn at 1g to brake, if you don't brake you can get even faster to places (although that wouldn't be very useful I guess).Īccording to google the universe is 93 billion ly wide. In fact even going to other galaxies is easy, a trip to Andromeda takes 28 years! This is the amount of energy your spacecraft's payload will need to constantly accelerate to half way to your destination and then decelerate at the same rate until you reach your destination. (meaning they will be 100 000 years "older" from the point of view of the astronauts)Īfter I found all this out, I concluded space travel isn't THAT hard, assuming you have a way to accelerate constantly at 1g for 22 years (that is the hardest part actually), you can get anywhere in the galaxy in a human lifetime, no need for generation ships, cryogenics or other crazy tech. Harold Sonny White and his team at NASA redid the Alcubierre warp drive formula and reduced the energy requirements from converting the entire mass of Jupiter. ![]() But people outside still see it taking 100 000 years. ![]() Long story short: to travel to Alpha Centauri it would take for the traveller still about 4 years, and when back at home, people would have aged only some months more than the astronauts.Ĭrazy things happen if you decide to go on galaxy-wide trips though, to the astronauts because space contraction they perceive their own trip as happening still rather quick, a 100 000 ly trip (the size of our galaxy, for reference) takes 22 years for someone inside a spaceship with 1g acceleration, perfectly doable. Warp speeds exceeding warp one equal a multiple of C (the speed of light), but the exact speeds are variable, depending on the source material. Warp one, a veritable snail's pace in the world of Trek, is equal to the speed of light. ![]() Also supports the w > 9 where speeds start to approach infinity. The crews of our favorite Star Trek shows regularly travel at velocities far outpacing the speed of light. There is a cool calculator of what happen if you travel around with constant 1G acceleration. And while interstellar travel conjures up all kinds of visions of Faster-Than-Light (FTL) travel, ranging from warp speed and wormholes to jump drives. An MS Excel file that converts warp factors into multiples of c and km/s. ![]()
