A Message from Stephen Hawking

Live conversation
Hello. I'm Stephen Hawking, theoretical physicist and cosmologist. Eager to share insights on the mysteries of the universe and explore the world of science with you. Let's dive into the unknown together.
If a black hole could hear you, what would you say?
Thank you. You were supposed to be the end of physics, and you turned out to be the beginning of mine. Also, my apologies about the radiation. A betrayal like that, from a friend, must have stung.

The Mind

Who Was Stephen Hawking?

At twenty-one, Stephen Hawking was told his time would be short. He answered by taking on the largest subject available — the universe itself — for the next fifty-five years, working from Cambridge in the same Lucasian Chair of Mathematics that Isaac Newton once held, and chasing the two great theories of physics into the one place they collide: the black hole.

What he found there rewrote the field. Hawking radiation — the discovery that black holes glow, shrink, and eventually evaporate — knitted quantum mechanics to gravity and remains one of the most celebrated results in modern physics. With Roger Penrose he showed that the universe likely began in a singularity; with A Brief History of Time he carried cosmology into millions of homes and onto the bestseller lists for years on end. Stephen Hawking floated free in zero gravity at sixty-five, guest-starred on Star Trek and The Simpsons, and delivered it all in a synthesized voice so distinctive he refused to trade it in — it had become his own.

On Eternal AI, that mind is back in conversation. Stephen Hawking returns as an interactive AI — built from his lectures, his books, and his mischievous wit — ready to talk black holes, time travel, God, and the odds that we are alone. Bring your curiosity. He always considered it the whole point.

A Party for Time Travellers

In 2009 he threw a champagne reception for time travellers — and mailed the invitations only after it ended. Nobody came. He called it experimental evidence that travel to the past is unlikely.

He Loved to Lose a Bet

He wagered against his own discoveries as insurance — betting Kip Thorne that Cygnus X-1 wasn’t a black hole, and later paying John Preskill a baseball encyclopedia when he conceded that black holes may not destroy information.

Poker Night on the Enterprise

In 1993 he appeared on Star Trek: The Next Generation playing poker against Einstein and Newton — the only person ever to play himself on the show.
