"The universe is a place of endless possibilities, and we are just beginning to explore them."

"The world would be a much better place if everyone had a clear, rational view of the universe."

"I believe that we are alone in the universe, but I hope we are not."

"The world is a dangerous place to live; not because of the people who are evil, but because of the people who don't do anything about it."

"The universe is a great place to be, and I'm glad to be a part of it. But it's also a very dangerous place, and we need to be careful."
