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

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 ...

Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

Gravity has become an unlikely viral villain, blamed for an imagined global blackout in which the planet briefly lets go of ...

The idea of emergent gravity is still new and requires a lot of assumptions in its calculations to make it work. But if experimental evidence ever proves it real, we would need to totally rewrite the ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

(via PBS Space Time) If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple theories that claim to do this, but it’s notoriously ...

Scientists have taken a major step toward solving a long-standing mystery in particle physics, by finding no sign of the particle many hoped would explain it. Baryons, composite particles made up of ...
