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

General relativity works well for large-scale objects ... For instance, it might explain why black holes don’t collapse, what ...

it’s actually by far the weakest of the four known forces of nature – and the only one not explained by quantum theory. Quantum theory and general relativity in fact don’t get along at all.

In 1915, Einstein published his paper on general relativity, a theory of gravitation. While Newton’s gravity explained ...

Despite explaining astronomical phenomena far better, general relativity became deeply unfashionable, as it failed to explain what happens deep inside the atom. Einstein’s big idea was the ...

After thinking about the problems for 10 years, he published the general theory of relativity. In it, he suggested that gravity is not a force, as Newton had believed, but the result of a ...

General relativity describes gravitation in a geometrical ... a phenomenon that is difficult to explain with existing models.

That wasn’t just wifely pride. Years before Hubble detected cosmic expansion, Einstein had fashioned a theory, general relativity, that could explain it. In studies of the cosmos, it all goes ...
