Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

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 ...

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.

Physicists hope that understanding the churning region near singularities might help them reconcile gravity and quantum mechanics. At the beginning of time and the center of every black hole lies a ...
