78,000 apply to leave Earth forever to live on Mars

I'm sure it's a one way trip with today's technology but let's not rule out what will be possible in 50 years' time at least.

Do you think space tech will advance enough for us to visit them in a few days time?

Please forgive not too clued up on astrophysics/spacetech

Time and space is constant, a object can not appear to break the speed of light. This results In a slowing of time as you gain higher speeds.

An example would be if I had a space ship the could travel at the speed light (impossible yes but let's live with it) and I traveled the distance of one light year before returning to earth. For me it might feel like one day to travel that distance because my time slowed down because of the speed I was travelling. However from the perspective of an observer on earth I would have been gone a year because he observes time differently to me.

Thus the problems with space travel at those speeds would not be the travelling but the return to life on earth.

I'm guessing that's why mass effect has those portals, to reduce the effect.
