In his new Discovery Channel documentary, Stephen Hawking states that humanity should attempt to avoid contact with advanced extraterrestrial life because it could be dangerous for mankind.
“If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans.”
Hawking’s reason for believing in alien life is strictly mathematical. With 100 billion galaxies, each containing hundreds of millions of stars, Earth is unlikely to be the only planet where life has evolved.
Stephen Hawking’s Universe begins on the Discovery Channel on Sunday May 9 at 9pm
