Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time: the interwoven fabric of space and time at the heart of Albert Einstein’s theory of relativity.

What if our biggest idea about reality is built on a hidden misunderstanding? A new philosophical look at space-time challenges the popular view that the past, present, and future all exist together ...

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 ...

The September read for the New Scientist Book Club was a challenging trip to the edges of space-time with Chanda ...

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 ...

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 ...

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 ...

Physicists aren’t known for playing fast and loose with the rules of reality. But when it comes to the concept of space, some take a remarkably permissive attitude. For most of us, it would seem there ...

Space and time seem like two completely different ideas, but Einstein showed they are interlinked in what is known as space-time. Here's what it means!

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 ...

The original version of this story appeared in Quanta Magazine. In the fall of 2022, a Princeton University graduate student named Carolina Figueiredo stumbled onto a massive coincidence. She ...
