At a sustainable g-force, how long would it take a normal human to accelerate to the speed of light?
Yes, I'd like some real science geeks to help me with this.
Factors:
1) The subject starts from a stand-still (relative to Earth).
2) We assume that even though the subject is gaining in mass as he approaches light-speed that the acceleration doesn’t slow.
3) We assume that the subject could be awake and be able to function reasonably that this g-force (i.e. eat, drink, play video games, change his clothes…)
4) Enlighten me as to what other physical problems might be encountered that I don’t know about.
Thanks!
speed of light divided by 9.80 m/s^2 = 30,591,067.14 seconds, which is 354 days 1 hour 31 minutes and 7.14 seconds.
That's how long it would take, accelerating at one gee.
Of course, your #2 assumption is impossible, because it would take more and more energy to accelerate the increasing mass (which approaches infinity as the speed approaches c).
If you increased the accelleration to 2 gee it would cut the time in half, but I don't think a person could function well that way.
