For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny particles, with general relativity, which explains the universe’s vast structures.

Forget the Turing test. In Sam Altman's world, the only verdict that matters comes from physicist David Deutsch.

During a recent fireside chat, OpenAI CEO Sam Altman posed a question about the future of AI and whether it was about to pass ...

Quantum gravity represents the ambitious quest to reconcile the principles of quantum mechanics with general relativity, aiming to produce a unified theoretical framework that can describe the ...

There is no question that quantum theory is correct. It’s been proven over and over, both in the lab and through practical achievement. But the question remains: is it always correct? Quantum ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...
