Ok, say a planet with earth-like qualities was discovered a light year away or so that was able to sustain human and animal life just as well as our planet. The world governments get together and after years of research and testing collectively build a huge space ship that will essentially be the "Noah's Ark" of space ships. A huge amount of animals will be put on board as well as 1,000 humans, 500 males and 500 females. When you got there you would not have shelter or anything, but you'd be sent with blueprints to recreate the technology known on earth, as well as a complete and exhaustive set of Encyclopedias with every bit of important human knowledge in them, a huge amount of books, etc. It would be estimated that you wouldn't see an earth level of living and technology for at least several hundred years though, which would obviously not be within your lifetime. The selection process would be random, but you'd have to apply and go through a bit of an ordeal to end up as one of the final 1000 humans to actually travel on to the distant planet and start a new life. If you were selected, not only would you never see anybody from earth again (unless of course they went with you), but you'd probably never communicate with earth again. The space shuttle would be able to put all of the animals into hibernation mode during the course of the journey which would last a total of 20 years. The humans would be able to remain awake and conscious. Food would be taken in the form of pills. There would be enough water for the journey as well. And yes, for the sake of the argument, you'd be guaranteed to make it there healthy and alive. The main downside is the 20 year journey. Would you toss your hat in the ring? Why or why not? I would not. It would be pretty awesome to be a part of such a mission but I wouldn't want to give up my life on earth, let alone 20 years waiting in space.
