Satellites detected a mysterious gravitational change beneath Earth's surface, suggesting rapid movement of interior masses.

A recent study proposes that gravity, the force shaping galaxies and anchoring planets, might not be fundamental after all.

Scientists may have found a new way to unlock the vast secrets of the Big Bang—the cosmic event thought to have kicked off the expansion of the universe billions of years ago. The revelation came in ...

Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold new line of research now argues that gravity is not fundamental at all, ...

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

The universe is expanding—that much is clear. The rate at which it expands is a bone of contention among scientists. The so-called Hubble constant accurately predicts how fast objects recede, but it's ...

Our universe would look so different, Kyle. You might not recognize it even if you could be here to see it. Unfortunately, there probably wouldn’t be a whole lot to see. I learned about this from ...
