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

Most people have never heard of vacuum decay, but if it happened it would be the biggest natural disaster in the universe. Sure, an asteroid could destroy a city or wipe out life on Earth. A supernova ...

I keep coming back to a strange idea: what if everything we know about quantum physics is already encoded inside a single atom? Not in a mystical sense, but in the very real way that one tiny system ...

The early universe experienced a phase of rapid expansion, known as inflation. For decades, cosmologists assumed that this expansion was powered by a new entity in the universe, known as the inflaton.

Physicists are still puzzling over the true nature of dark matter and dark energy, because they have inexplicably added 10 times as much mass as normal matter has to the universe. Looking at the ...

The earliest acoustic vibrations in the cosmos weren’t exactly sound – they travelled at half the speed of light and there ...

Nearly 50 years ago, physicists floated a bold idea: our universe might be stuck in a false vacuum. This state feels stable, but deep down, it's not. Over enormous timescales, it could suddenly tip ...

Scientists using Google’s quantum processor have taken a major step toward unraveling the deepest mysteries of the universe. By simulating fundamental interactions described by gauge theories, the ...

Recent progress in both analog and digital quantum simulations heralds a future in which quantum computers could simulate — and thereby illuminate — physical phenomena that are far too complex for ...

The universe may have been born out of nothing, with an "anti-universe" twin where time runs in the opposite direction—rather than exploding from an infinitely small and dense point, or "singularity." ...
