Boosting one term in a complex equation helps scientists explain how the results could change. Scientists in Greece have laid ...

Physicists have long assumed that the universe is pretty much the same in any direction, and now they've found a new way to test that hypothesis: by examining the shadow of a black hole. If that ...

If there's one thing everybody knows about space, it's that there's no gravity once you leave the Earth's atmosphere. We all know that don't we? It's actually not true — and an attempt at a massive ...

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By ...

A new model of the Universe suggests that modifying Newton's theory of gravity could do away with the need for dark matter. The model instead relies on an as-of-yet undiscovered form of gravity to ...

A pair of spacecraft that meticulously mapped the moon's gravitational field has helped astronomers solve the long-standing mystery of why the moon is so gravitationally lumpy. A team of scientists ...

Harvard's Avi Loeb says interstellar comet 3I/ATLAS may show forces beyond gravity. Scientists using JWST and Swift report unusual chemistry but urge caution.
