It’s been 120 years since Henry Cavendish measured the gravitational constant with a pair of lead balls suspended by a wire. The fundamental nature of gravity still eludes our best minds - but those ...

The original version of this story appeared in Quanta Magazine. When it comes to understanding the fabric of the universe, most of what scientists think exists is consigned to a dark, murky domain.

As its name suggests, dark matter — material which makes up about 85% of the mass in the universe — emits no light, eluding easy detection. Its properties, too, remain fairly obscure. Physicists have ...

Extra dimensions sound like science fiction, but they could be part of the real world. Extra dimensions sound like science fiction, but they could be part of the real world. And if so, they might help ...
