Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

We have long taken it for granted that gravity is one of the basic forces of nature–one of the invisible threads that keeps the universe stitched together. But suppose that this is not true. Suppose ...

Physicists have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery ...

Dr Charles Buhler takes people through his lab in a new video. He explains more about how they developed and detected a new force from large electrostatic pressure differences. They claim this force ...

Gravity, a fundamental force we take for granted, might be more mysterious than we ever imagined. A groundbreaking study has emerged, challenging long-held beliefs about gravity and its nature. This ...

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 ...

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

Centuries before anyone pointed a telescope at the sky, Isaac Newton figured out how gravity works. He showed that any object with mass pulls on every other object—a result that explained falling ...
