Yeah that would be impossible for our generation but it's still a cool dream. Exploring space, colonize on other planets, heck space colonies. Makes me sad knowing that I will never live to see this day come.
Yeah, I'm taking an astronomy course at the moment, and I've always had a passion for space. I'm sure there are plenty of planets out there that humans could live on, but we are just too primitive a species (right now anyway) to travel the universe.
