The most discreet dwarf galaxies in our Universe reveal a gravitational anomaly that has intrigued astronomers for decades. While large spiral galaxies seem to follow well-established rules, ...

A recent preprint claims that we may someday be able to create gravitational waves in a lab. Through the use of “twisted” light, we could create powerful, high-frequency waves in a controlled setting.

Physicists have measured the gravitational field of a smaller object than ever before, a gold sphere with a mass of about 90 milligrams. This could help us understand how gravity fits together with ...
