44 light years away? okay so even if we master light speed travel, it would still take 44 years to get there. i dont think we'll be emigrating anytime soon

Right, with the so horribly short Human lifespan of average 98 years, as well as advances in cryogenic freezing, it's such a horrible low possibility that ANYONE would live to see the end of the journey...

theoretically, once the space ship reached the speed of light it would slow down the time passing for the people in the ship. so even if it took the ship a couple of years to get to the speed of light, the people inside the ship might only age a few years. 44 years would go by for people on earth, but the people on the ship would only live through a few years.

according to the theory, someone moving at the speed of light wouldn't age at all.

But that's impossible. You can't travel at lightspeed, nothing with a noticable mass could, because mass grows the closer you get to the speed of light anyway, that doesn't mean that we wont find a way to travel faster, wormholes, hyperspace..

i meant they would age a few years just from the time spent while the ship was speeding up or slowing down. that process could take some time to do. they think that they could possibly travel faster then light by collapsing space in front of the ship, and expanding the space behind it.

of course the ship would move, but it would move right into the collapsed space, and probably collapse together with it.

And collapsing space isn't really easy, I mean it is possible, or could be, but that's just a naked idea, you would need much more than that idea to actually make it work, we probably wont live long enough to witness mankind colonizing another planet, but it will happen, I'm sure.

i can't find the link that explained the concept of how it's done or why it's possible. sorry i can't really explain better.

Actually it would take 44 years for people on earth but not for those aboard the spacecraft.

How is that?

General theory of relativity. As you approach the speed of light time slows down and space begins to warp. In theory if you were to travel at the speed of light, for observers on earth it would take 44 years, for the people traveling it would be instantaneous.

Thats amazing, so what you are saying is that the people going to that planet would arrive there instantly? But 44 years would have passed?

If they were to travel at the speed of light, yes.

Basically. They also essentially wouldn't age a day in Cryosleep.
