Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

The proposed BMV experiment could test whether gravity is quantum, a breakthrough that may lead to quantum computers and ...

No one can question the impact of science on human civilization, and the importance of experimentation in science is equally undeniable. Some experiments confirm what we already know, others suggest a ...

To learn more about the nature of matter, energy, space, and time, physicists smash high-energy particles together in large accelerator machines, creating sprays of millions of particles per second of ...

The original version of this story appeared in Quanta Magazine. There are precision measurements, and then there’s the Laser Interferometer Gravitational-Wave Observatory. In each of LIGO’s twin ...

Buried deep below the American Midwest, a new kind of observatory is taking shape that aims to watch some of the most elusive particles in the universe as they stream straight through Earth. The Deep ...

A chameleon-like force that shifts its nature based on its environment could explain a major physics quandary: how the mysterious substance called dark energy is compelling the cosmos to expand faster ...

The universe began about 14 billion years ago with a single point that contained a vast array of fundamental particles, according to the prevailing theory known as the Big Bang. Under the pressure of ...

To build the DUNE neutrino experiment and its associated accelerator upgrade, experts invent customized ways to transport fragile, expensive and highly specialized components. On a late-September day, ...

We tend not to dwell on the fact that we exist in three dimensions. Forwards-back, left-right, up-down; these are the axes on which we navigate the world. When we try to imagine something else, it ...
