A new experiment involving a network of entangled atomic clocks could finally help us test how quantum mechanics fits with ...

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 ...

Physicists are rethinking time itself. Long treated as a basic part of the universe, time may instead be an illusion—a side ...

There are two theories we have that explain all the particles and their interactions in the known Universe: General Relativity and the Standard Model of particle physics. General Relativity ...

The MICROSCOPE experiment was designed to test Einstein's theory of general relativity. (Image credit: ONERA) The team's results, which are the culmination of 20 years of research, revealed that ...

General relativity provides an explanation for how massive objects warp the fabric of space ... Now the experiments have been improved and physicists have amassed some 50 such events so far, ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity's limitations on the ...

Gravity gets the 'spooky' treatment. It is maybe fitting that general relativity and quantum physics don't get along; after all, Einstein was never comfortable with quantum physics. This is ...

If general relativity matched LIGO's measurements when pi was not close to its true figure, that would be a sign that the theory was only half-baked. ... The Geiger-Marsden experiments explained.

Albert Einstein's discoveries changed our concept of gravity by adding revolutionary layers to Isaac Newton's theories. Here's what else Einstein did.

Einstein's general relativity says experiments should come out the same way, no matter where they are in space and time. A new NIST experiment backs that up, using Earth itself as the lab.

The special theory of relativity, published by Einstein in 1905, introduced a new understanding of space and time, including the equation that linked energy, mass and the speed of light: E = mc².
