The concept of spacetime, first described in Einstein's theory of general relativity, has since been widely studied by many ...

A new recipe of "quadratic gravity" could help to better define the picture of the Big Bang and the singularity that existed ...

Gravity feels constant, almost invisible. It holds oceans in place and keeps us grounded, so we rarely question it. Yet every ...

Measuring the strength of gravity is extraordinarily difficult, and different experiments have always disagreed – but a new ...

From Newton’s apple to Einstein’s spacetime, gravity has been tested on scales from sub-millimeter experiments to galaxy clusters millions of light-years apart. Recent studies confirm its laws hold ...

One of the best-performing models in cosmology is also one with the least physical rationale behind it. Columnist Leah Crane ...

Research shows Mars' gravitational pull affects Earth's deep-sea currents and climate, causing warming cycles every 2.4 ...

Why do astronauts squeeze objects too hard? A new study explains how the brain's internal gravity model persists in space, leading to overcompensated grip strength.

We have long taken it for granted that gravity is one of the basic forces of nature—one of the invisible threads that keeps the universe stitched together. But suppose that this is not true. Suppose ...

After a 10-year effort, physicists got a value for “Big G” that does not settle the debate over one of nature’s hardest numbers to nail down.
