Last Words

“If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans. We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.”

- Stephen Hawking (1942-2018), theoretical physicist
