Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: ...

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity.

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it ...

Researchers have, for the first time, observed tiny voids in phonon-polariton waves moving faster than light, without violating Einstein’s theory of relativity. Using ultrafast electron microscopy on ...

Yesterday, I wrote about the core concepts needed to understand quantum physics, which is one of the two pillars of modern physics. The other, of course, is the theory of relativity, the full and ...

For the first time, researchers measured singularities in combined light and sound waves moving faster than the speed of ...
