Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein's General Theory of Relativity, published in 1915, an entirely classical ...

Recent decades have witnessed remarkable progress in establishing rigorous mathematical frameworks for quantum field theory (QFT), conformal field theory (CFT), quantum gravity and string theory.

Tiny but ageing neutrinos can be used to test the very foundations of quantum theory at unprecedented cosmological time scales Schrodinger’s skinniest kittens Must the Schrodinger’s Cat be fat enough ...

--- Davide De Biasio received his PhD in theoretical physics from the Max Planck Institute for Physics, where he studied black holes, string theory and the enigmas of quantum space-time. Today, he ...

The original version of this story appeared in Quanta Magazine. String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a ...

String theory—the idea that particles are not point-like, but instead one-dimensional strings—is a popular theoretical framework that attempts to combine general relativity and quantum field theory ...

String theory's equations give rise to a near infinite variety of potential universes in a 'landscape.' This landscape is surrounded by a 'swampland' of solutions that are incompatible with any ...

WEST LAFAYETTE, Ind. — A team of Purdue University researchers has been awarded a $1 million W.M. Keck Foundation grant to experimentally test an early prediction originated from string theory: An ...

Published January 7 in the journal Nature, one paper tackled the age-old problem of nature’s construction with a bit of a twist: it suggests that living networks, like our brain, may use some of the ...
