What if our biggest idea about reality is built on a hidden misunderstanding? A new philosophical look at space-time ...

In holographic theories, physicists may have traced the pliability of space-time to its quantum roots: a measure of ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

Most of today’s leading theoretical physicists have a shared perspective about what the next revolution in physics will look like. They think reconciling Albert Einstein’s general theory of relativity ...

Imagine slipping into a multiplayer VR version of Grand Theft Auto, racing cars against players scattered across the world.

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

Whether space-time exists should neither be controversial nor even conceptually challenging, given the definitions of “space-time,” “events” and “instants.” The idea that space-time exists is no more ...

One of the most awkward parts of writing a book is that, eventually, authors have to ask people for “blurbs” – the endorsements that you see on the cover of a book, encouraging you to buy it. I am now ...

Big G, gravity, is the oldest fundamental constant in physics and the least clearly defined. One scientist has spent a decade ...
