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 ...

What does it mean to be to space-time? The seemingly simple question gets to the essence of twentieth-century physics and has driven a hundred-year debate between philosophy and science. In Einstein’s ...

What if time were the only truly fundamental dimension of our Universe? A recent theory proposes a radically different vision of reality, where time has three dimensions. This approach challenges our ...

The supermassive black hole at the center of our galaxy, Sagittarius A*, is spinning rapidly and altering space-time around it, a new study has found. Space-time is the four-dimensional continuum that ...

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 ...

What if intelligence isn't one thing, but two curious dimensions—and AI just revealed the hidden rift we never knew existed?

The first time a physicist told me they wanted to get rid of space-time, on a cold January morning earlier this year, I stopped typing my interview notes and clutched my New Scientist mug of tea.

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 ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...
