>>12491924Every physical process, as far as we know, is slowed down when moving at relativistic speeds
>>12492075If you were go to Alpha Centauri traveling at 0.99995 times the speed of light, the clock on your ship would be moving 100 times slower than a stationary observer, and you would age 100 times slower as well. You'd age around .0437 years on the outbound journey and .0437 years on the return journey.
So, you'd come back .0874 years (32 days) older but 8.74 years would have elapsed on Earth
You could just as easily choose a destination 50 light years away traveling at the same speed, come back in after having experienced only one year and see the Earth in 2120
You may ask "well if I can't go faster than light how can I get to Alpha Centauri in just 32 days?"
From your perspective the distance to Alpha Centauri shrinks
