In case that we, humans, can live there, I think it is impossible for all of us to get there. It will takes a lon period of time. Plus, rich people will the only one to get there.
If there was no imperfection in the world, people would live forever... in excellent health. Think of all the scientific knowledge that could have been gained so far, by people never dying so that their children have to relearn the knowledge.
Go to http://www.luminist.org/archives/, scroll down to "Ray Bradbury," and download, for free, a copy of his book "R is for Rocket." It is in PDF format, and is available, free.
Then look in the book for the short story "Frost and Fire," at page 160. It's a good read.
The point is, we are like the people of "Frost and Fire." We should all be living for thousands of years, at least. The planets out there were made, by God, for us to go to in a time when there would be standing room only on the earth. If we had not turned against God, He would have found a way long ago for us to go to the stars.
