What did Newton understand that was such a revolution? Can someone just... explain gravity to me? Let's start with a ...

Traditional black holes, as predicted by Albert Einstein's theory of General Relativity, contain what are known as ...

Space-time may hide a bizarre new kind of black hole that causes Einstein’s theory of gravity to fail – and could solve the mystery of dark energy ...

Traditional black holes, as predicted by Albert Einstein's theory of General Relativity, contain what are known as singularities, i.e. points where the laws of physics break down. Identifying how ...

Scientists uncover secrets of black holes using quantum computing and machine learning, revealing new insights into space, ...

From unifying quantum physics and gravity to working out what is dark matter, the universe has some deep questions that remain unanswered.

The theory is a series of equations defined by Einstein. These equations combine space and time to create space-time. Gravity is explained by these equations, which are consistent with what we see ...

Armed with this and a new conception of space and time as an interwoven “space-time”, you can construct a picture in which gravity is just a form of acceleration. Massive objects bend space ...

The pull of gravity is just matter sliding along the curvatures of space-time. Einstein shot to the pinnacle of celebrity in 1919, when British astronomers actually measured this warping.

There’s so much mass in this megacluster that its gravity warps the fabric of spacetime to create a natural super-magnifying glass called a “gravitational lens.” It’s that which has ...
