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

Decades after it became clear that the visible Universe is built on a framework of dark matter, we still don’t know what dark matter actually is. On large scales, a variety of evidence points toward ...

A variation on the theory of quantum gravity — the unification of quantum mechanics and Einstein's general relativity — could help solve one of the biggest puzzles in cosmology, new research suggests.

Astronomers have attempted to explain the non-gravitational acceleration of comet 3I/ATLAS, our third confirmed interstellar visitor, in a way that removes the need for "non-natural hypotheses for ...

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 ...

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 ...

Geologists have long been captivated by the Indian Ocean's "gravity hole," where the Earth's gravitational pull weakens, its mass falls, and sea levels drop by about 328 feet (100 meters). After years ...

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 ...
