"The great thing about science is that it doesn't ask for your faith, it just asks for your eyes."

"When you look at the universe, you realize how insignificant we are. But then you realize how significant we are, because we are the universe looking at itself."

"I don't think there's any such thing as a 'dumb question' when it comes to science. There are just questions that reveal a lack of information."

"There's no law that says you have to like science to be a scientist. Some people just want to make money."

"I'm not saying that science has all the answers. I'm saying that science is the only way we're going to get answers."
