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

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

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

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 ...

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

Astronomers have seen spacetime itself wobble near a spinning black hole for the first time. The discovery, revealed during a star’s destruction, confirms a major prediction of Einstein’s theory of ...

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 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 ...

If you wave your hand in front of your face, you won’t notice anything particularly interesting. Perhaps a gentle waft of air against your cheek – that’s about it. No epiphany. No major sign that ...
