There have been hundreds of exoplanets discovered, which is amazing enough, but none as close to resembling Earth as Kepler-22b. Granted, it's about two and a half times the size of Earth, and it's so far away that we'll probably never reach it, but our goal as humans should be to discover what exists outside our solar system. Hell, most people need to discover what exists outside their own backyard. Even Stephen Hawking said recently that the survival of our species depends on us colonizing new worlds. It will probably start with moon bases, and then we'll take over Mars, but once we really figure out space travel, it will be a glorious Star Trek time that I wish I could live to see. I think my best bet is having myself frozen and thawed in the future like Fry in Futurama. What do you think? Will humans ever make it out of the solar system, or will we kill ourselves first?
