"It's actually profound either way. If we find out that the universe is teeming with life and other civilizations, and we can learn about them, that would be spectacular; maybe it's like the archaeology of our future," Tyson said. "If we found out that we're all alone, that is also profound. It means life is extremely precious, and we better take care of life on this planet."
Looking up and wondering about our place in the universe, and how it all began, is an ancient and constant preoccupation of mankind. Tyson, who has devoted his life to that search, says, "It may be fundamental to what it is to be alive. To what it is to be human."
