This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

Can a single particle have a temperature? It may seem impossible with our standard understanding of temperature, but columnist Jacklin Kwan finds that it’s not exactly ruled out in the quantum realm ...

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing ...

In the strange corner of modern physics where spacetime itself becomes the engine, the old rule that nothing can outrun light ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

This is where Emmy Noether, a groundbreaking German mathematician, comes into the picture. She found a breathtakingly simple ...

The second paper, "Fermion Chirality from Non-Bipartite Topology," applies this same lattice geometry to the quantum world. It proposes that the "handedness" (chirality) of subatomic particles is not ...
