Space-time

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.

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

Two independent papers vanquish lingering doubts about LIGO’s historic discovery of gravitational waves.

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

On November 16, 2018, more than 200 readers joined writers and editors from Quanta Magazine for a wide-ranging panel discussion that examined the newest ideas in fundamental physics, biology and mathematics research.

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.

New findings are fueling an old suspicion that fundamental particles and forces spring from strange eight-part numbers called “octonions.”

Mathematicians have disproved the strong cosmic censorship conjecture. Their work answers one of the most important questions in the study of general relativity and changes the way we think about space-time.

A recently proposed experiment would confirm that gravity is a quantum force.
