Progress in the foundations of physics is moving slowly. And yet it moves. Today I look at the five biggest problems in ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

Of the four fundamental forces of physics, gravity is the one we’re most familiar with in everyday life, but it’s also the only one that can’t currently be explained by quantum physics. Now scientists ...

Astronomy is, in essence, an exercise in inference. We cannot touch the stars, nor scoop up galaxies in a lab. Instead, we ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. A newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

Do dead stars glow? A strange gravitational phenomenon could be generating enormous amounts of light around neutron stars, new research suggests. When you purchase through links on our site, we may ...

If you would like to learn more about how the Nobel Prize for Physics is awarded, check out this profile of Lars Brink, who ...

In the 95 years we’ve known about antimatter, physicists have not tested how the elusive inverse of ordinary matter is affected by gravity, the force that pulls masses to Earth and seems to affect all ...

Recent advances in theoretical physics have increasingly highlighted the pivotal role of algebraic structures in unifying particle physics with quantum gravity. These approaches leverage sophisticated ...

China successfully debuted a powerful centrifuge that could support scientific pursuits across a variety of fields.
