It is a utopia, and you do not need to be a scientist or expert researcher [to understand what will pass]. You just sit back, twiddle your thumbs, enjoy your beer, and wait until it fails. [Space colonization] will fail.
My explanation is a little more mundane in explanation, if not in concept. My mind goes back to a story I heard long ago about a woman who went on a cruise. She was talking with a man who figured out very quickly she wasn’t happy.
“I left my husband, I left my home, I left my city, I left my family, I left everything behind,” she told the man. “All of these things were making me miserable.”
“So why aren’t you happy?” the man asked her.
“Because I brought myself,” she replied.
I always think of my mother when I hear this; she took a Caribbean cruise after she divorced my father and wrested the family business from him. Her subsequent course in that business–and with the rest of us–wasn’t a very happy experience for anyone.
But in reality, as long as we carry our sinful, self-centred natures with us, utopia will remain just that, and our colonization of other planets will have the same result–or worse–than our colonization of the one we live on.
