Stephen Hawking warns us not to encourage aliens

ShawkingMore than 20 years after writing  A Brief History of Time, Hawking offers a fresh perspective charting the history of the universe, from the awe-inspiring energy of the big bang to the end of time itself. Stephen Hawkings Universe for the Discovery Channel will be on our screens next month.

The renowned astrophysicist says in the series that it is “perfectly rational” to assume intelligent life exists elsewhere. The universe, he points out, has 100 billion galaxies, each containing hundreds of millions of stars and Earth is unlikely to be the only planet where life has evolved.

Although there may be other life forms out these, he warned that aliens might simply raid Earth for resources, then move on.

“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,” he said.

Professor Stephen Hawking warns that rather than actively trying to communicate with extra-terrestrials, we should do everything possible to avoid contact with them as “We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet.”

In the past, probes have been sent into space with engravings of human beings on board and diagrams showing the location of our planet and radio beams have been fired into space in the hope of reaching alien civilisations.

Stephen Hawking’s Universe begins on the Discovery Channel on Sunday May 9 at 9pm.
