Physicists have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery ...

Foreword / Diana Kormos Buchwald -- Preface -- Part I. Preliminaries. Introduction -- Einstein's first trip to America -- Structure and contents of The meaning of relativity -- Part II. The emerging ...

A team at UNIGE has uncovered a geometric structure once thought to be purely theoretical at the core of quantum materials, opening the door to major advances in future electronics. How can ...

Quantum gravity seeks a consistent framework to merge the principles of quantum mechanics with general relativity, addressing the challenges of formulating a quantum field theory for the gravitational ...

FLAMINGO simulation maps the universe but reveals a puzzling mismatch: galaxies cluster less than theory predicts.

In 1998, a gentleman by the name of John Titor arrived from the future, or so he said. In his timeline, as he claimed, ...

A South Korean physicist has proposed a theoretical framework that could support the unification of quantum mechanics and the ...

Black holes are among the most extreme objects in the universe, and now scientists can model them more accurately than ever ...

Gravitational waves from black holes may soon reveal where dark matter is hiding. A new model shows how dark matter surrounding massive black holes leaves detectable fingerprints in the waves recorded ...

Anduril founder Palmer Luckey speculated about UFOs during a conversation about why modern stealth aircraft no longer rely on ...

Astronomers have finally captured a black hole twisting the very fabric of spacetime. This phenomenon, known as ...

A new concept for energy transfer between gravitational waves and light. When massive cosmic objects such as black holes merge or neutron stars crash into one another, they can produce gravitational ...
