Famous Physicist Stephen Hawking warns against prospect of hostile aliens, says he’s sure ‘we are not alone’

Contacting aliens, especially those more technologically advanced than humans could be dangerous for humanity, warned British physicist Stephen Hawking in a new online film. 

The author of all-time international bestseller ‘A Brief History of Time’, Hawking equated  humans  first contact with an advanced civilisation to Native Americans first encounter with Christopher Columbus. Things “didn’t turn out so well”, Hawking said.

The film, “Stephen Hawking’s Favourite Places”, takes viewers to five significant locations across the cosmos, on his spacecraft - the SS Hawking.

In the film, Hawking performs a hypothetical flyby of Gliese 832c, a potentially habitable exoplanet located 16 light years away.

“One day we might receive a signal from a planet like Gliese 832c, but we should be wary of answering back,” he said.“They will be vastly more powerful and may not see us as any more valuable than we see bacteria,” Hawking warned.

“As I grow older I am more convinced than ever that we are not alone. After a lifetime of wondering, I am helping to lead a new global effort to find out,” he was quoted as saying by ‘The Guardian’.

It is not the first time Hawking has warned about the prospect of hostile aliens.

Launching the Breakthrough Listen project, which will scan the nearest million stars for signs of life, last year Hawking had suggested that any civilisation reading our messages could be billions of years ahead of humans.

“The Breakthrough Listen project will scan the nearest million stars for signs of life, but I know just the place to start looking,” he said, in the film that appeared on the online platform CuriosityStream.
