Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama themselves. A new theoretical framework now flips that script, treating space ...

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 ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Two cutting-edge atomic clocks — the most accurate ever ...

The answer comes from a counterintuitive result of special relativity, a field of physics which is notoriously difficult to ...

A mathematical test for the nature of space-time – the fabric of physical reality – may be the first step towards novel computer-like devices that process information using gravity. Eleftherios-Ermis ...

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 ...

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...
