Researchers at IPhT (CEA, CNRS) and the Universitat Autònoma de Barcelona have shown that gravity—and with it, ...

Most current models of the Big Bang rely on general relativity along with additional elements that are introduced to make the theory fit observations. In contrast, this new framework provides a more ...

Researchers have demonstrated that pairs of helium atoms can exist in two places at once while remaining linked in motion by ...

A Gravity Theory That Could Rewrite the Universe’s First Moments The first fraction of a second after the Big Bang has always ...

Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests ...

Scientists show helium atoms can exist in two places at once, preserving quantum behavior even as they fall under gravity.

A new experiment with momentum-entangled helium atoms could help unite quantum mechanics and general relativity.

A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept of quantum gravity does not exist. The idea comes from two London-based ...

A team of physicists have proposed a new idea for uniting quantum mechanics and gravity, which they believe could explain the ...

Scientists have taken lasers beyond light and into the realm of sound, creating a breakthrough “phonon laser” that ...

Scientists at the University of Waterloo have uncovered a bold new way to explain how the universe began—one that could ...

A new physics paper proposes modifications to Einstein’s theory of relativity that could solve one of the biggest issues ...
