Albert Einstein’s general theory of relativity is one of the towering achievements of 20th-century physics. Published in 1916, it explains that what we perceive as the force of gravity in fact arises ...

Although general relativity (GR) is an elegant theory of gravity, we don't often need to use it. For most gravitational ...

Our understanding of the universe may be completely wrong.

The nature of light and photons reveals deep insights into spacetime, showing how they traverse without time, reshaping our ...

The Big Bang is often described as the moment everything began — a point of infinite density where the laws of physics broke down. But what if that picture is incomplete? A new study proposes a ...

Long and winding road: The Juice space probe taking the long way to Jupiter and its moons – Copyright NASA/AFP/File NASA Scientists have unveiled a new theory that ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...
