If true, the idea would blow past one of physics’ most sacred limits: that parallel versions of reality can never talk to ...

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

Physicists at Heidelberg University have developed a new theory that finally unites two long-standing and seemingly incompatible views of how exotic particles behave inside quantum matter. In some ...

Physicists have developed a new theory that brings together two major areas of modern quantum physics. The work explains how a single unusual particle ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other. Quantum theory governs particles and fields, while Einstein’s gravity describes ...

Quantum physics paints a strange picture of the world, one filled with spooky connections, unsettling uncertainties ...

An old puzzle in particle physics has been solved: How can quantum field theories be best formulated on a lattice to ...

A cluster of 7,000 sodium atoms has just been coaxed into behaving as a single, ghostly wave, stretching quantum weirdness ...

The original version of this story appeared in Quanta Magazine. 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 ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...
