Question

If I was traveling at 70% the speed of light, one second in my spaceship would equal how many seconds on earth?

Answer 1

Isn't a second the same no matter where it is? It's a measurement of time not speed.

Answer 2

The person moving at 70% of the speed of light would not notice any change but from the persective of the person on Earth the change would be described by what is know as a lorentz contraction.

the apparent change = sq rt (1-V^2/C^2) :1 where C is the speed of light and V is epressed a percentage of the speed of light.

sq rt (1-.7^2/1)  = sq rt (1 -.49) = sq rt .51 = .7141

the second would appear to the person on Earth  as being

1/.7141 seconds = 1.4 seconds

Answer 3

Due to the effects of relativity at such a high speed, you time would be moving much slower and the earth would appear to zip around the sun.
