Will we ever colonize on another planet?

There are several Earth-like planets out there, but the question is, will we ever go there and inhabit it? Please give the Star system we would most likely go to, and why that plane, and how far it is from Earth.

  • Nov 30 2011: This will always depend heavily on economics. Currently, I believe it costs about $10,000/pound to boost mass into orbit. Obviously, boosting to another planet will cost more (although I'm sure you'd try to mine moons/asteroids for much of your mass).
    So, long before you see extraterrestrial colonization, you'll have to have space elevators and significant space industry.
    I also suspect you'll see a lot of oceanic colonization long before space colonization. Ocean-top or underwater dwelling is *far* more hospitable and inexpensive than extraterrestrial living.
    • Nov 30 2011: You seem to be very knowledgable in this field. How would we deal with Oceanic weather? or even currents?
