General relativity stands as one of the bedrock theories in modern physics. Its strange view of relative time and space has been confirmed by countless experimental and observational tests, from ...

Three physicists have proposed a modification to Einstein’s general relativity that, if confirmed, could eliminate the ...

A new physics paper proposes modifications to Einstein’s theory of relativity that could solve one of the biggest issues ...

For over a century, scientists have been intrigued to decode the perplexing scenery behind contemporary physics. It's been up for many years, and yet the experts still have no idea how to bridge the ...

In 1916, only a year after Albert Einstein had published his general theory of relativity, Karl Schwarzschild used mathematical calculations to show this: If sufficient mass could be placed into an ...

Einstein was right: artist's impression of a neutron-star merger. (Courtesy: NASA) Multimessenger observations of neutron stars have been used by astrophysicists in the US to put Einstein’s general ...

A new experiment with momentum-entangled helium atoms could help unite quantum mechanics and general relativity.

So far, the most accurate model describing gravity is still Einstein’s theory of general relativity. It states that gravity as we feel and observe it is a kind of side effect of the fabric of ...

Most current models of the Big Bang rely on general relativity along with additional elements that are introduced to make the ...

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 ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...

One of the biggest problems with physics is that, apart from a few mysteries we cannot adequately explain, the things we do understand work extremely well. Too well, in fact, for our comfort. Almost ...
