“To my mathematical brain, the numbers alone make thinking about aliens perfectly rational.”
Don’t talk to aliens, warns Stephen Hawking

“[Stephen Hawking] has suggested that extraterrestrials are almost certain to exist — but that instead of seeking them out, humanity should be doing all it that can to avoid any contact…”
“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.”
“Hawking’s logic on aliens is, for him, 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,’ he said. ‘The real challenge is to work out what aliens might actually be like.’”
