Aliens indeed exist: Stephen Hawking

Do aliens exist? They do, but humans should try to avoid any contact with them -- at least, that's what one of the world's leading physicists, Stephen Hawking, claims. And Hawking's logic on aliens is unusually simple, read on.

Do aliens exist? They do, but humans should try to avoid any contact with them -- at least, that's what one of the world's leading physicists, Stephen Hawking, claims.

The suggestions, that the extraterrestrials are almost certain to exist, come in a new documentary series for 'Discovery' channel, in which Hawking will set out his latest thinking on some of the universe's greatest mysteries.

Alien life, he will suggest, is almost certain to exist in many other parts of the universe -- not just in planets, but perhaps in the centre of stars or even floating in interplanetary space, 'The Sunday Times' reported.

Hawking's logic on aliens is unusually simple.

The universe, he points out, has 100 billion galaxies, each containing hundreds of millions of stars. In such a big place, Earth is unlikely to be the only planet where life has evolved.

"To my mathematical brain, the numbers alone make thinking about aliens perfectly rational. The real challenge is to work out what aliens might actually be like," the 68-year-old was quoted as saying.
