Physicists have devised a holographic model of “de Sitter space,” the term for a universe like ours, that could give us new clues about the origin of space and time.

Perfect black holes are versatile mathematical tools. Just don’t mistake them for the real thing.

People have known about magnets since ancient times, but the physics of ferromagnetism remains a mystery. Now a familiar puzzle is getting physicists closer to the answer.

The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness.

The renowned physicist Leonard Susskind has identified a possible quantum origin for the ever-growing volume of black holes.

Experiments suggest that exotic superconducting materials share a “strange metal” state characterized by a quantum speed limit that somehow acts as a fundamental organizing principle.

In the latest campaign to reconcile Einstein’s theory of gravity with quantum mechanics, many physicists are studying how a higher dimensional space that includes gravity arises like a hologram from a lower dimensional particle theory.

A new theory proposes that the quantum properties of an object extend into an “atmosphere” that surrounds the material.

Cosmologists have predicted the existence of an oscillating signal that could distinguish between cosmic inflation and alternative theories of the universe’s birth.
