Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the ...

General relativity, also known as the general theory of relativity, is the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern ...

Testing General Relativity with Current Cosmological Data Authors: Scott F. Daniel, Eric V. Linder, Tristan L. Smith, Robert R. Caldwell, Asantha Cooray, Alexie Leauthaud, Lucas Lombriser Abstract: ...

But simple it isn’t. General relativity’s equations fail catastrophically at a black hole’s centre, known as its singularity, where the warping of space-time simply goes off the scale.

1915 Albert Einstein had described the special theory of relativity in 1905. The result of Einstein's thinking about light, this theory introduced brand-new ideas to science.

The researchers are also tracking other stars, including S0-102 which orbits the black hole every 11.5 years. "General Relativity has a hard time describing things that are very small, but has a lot ...

General Relativity (GR): Einstein’s theory describing gravitation as the curvature of spacetime. Modified Gravity Theories (MGTs): Alternative frameworks that extend or alter GR to address ...

Over 100 years ago Einstein first described his general theory of relativity. This theory had a profound effect on physics and our understanding of the universe. But does it still matter today?

Einstein’s general theory of relativity has triumphed once again after being tested in the strongest gravitational field to date. Dimitrios Psaltis at the University of Arizona and members of the ...
