For nearly a century, astronomers have watched galaxies spin and the universe expand in ways that visible matter alone cannot ...

From the fall of an apple to the glow of the farthest known star, gravity quietly choreographs almost everything that happens ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

In 1919, physicist Theodor Kaluza hypothesized that extra dimensions might solve some outstanding problems in physics. And while we haven't found any evidence yet for anything outside our normal ...

Brian takes a fresh look at the concept of gravity, revealing it to be far more than just the force that makes things fall to the ground. Recent scientific breakthroughs are challenging physicists' ...

If you wave your hand in front of your face, you won’t notice anything particularly interesting. Perhaps a gentle waft of air against your cheek – that’s about it. No epiphany. No major sign that ...

A mathematical test for the nature of space-time – the fabric of physical reality – may be the first step towards novel computer-like devices that process information using gravity. Eleftherios-Ermis ...

Physics is this close to understanding the entire universe. And what lives in this gap? Many physicists think it’s the elusive graviton—the quantum particle of gravity—whose discovery will finally ...
