Loosely quoted from Star Talk Radio:

“It seems to me that science is the only human collaboration that transcends human boundaries. The results you find are independent of what country you come from, what religion you believe in, what government you have. So when you think of what is the future that could possibly unfold in a world that is divided by politics, by religion and by any other reason people give to kill another person for crossing a line in the sand, it tells me that the only hope we have is to search for the truth that we find through the research conducted by science.”
