If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy.

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.

They have accepted two separate theories that explain how the universe works: Albert Einstein's general theory of relativity, which describes the universe on a very large scale, and quantum ...

Supermazes” are theoretical structures that provide a fresh blueprint for understanding the microscopic complexity of black ...

By modifying Einstein's theory of general relativity, the center of a black hole with infinite curvature could be replaced by a highly curved but regular region of space-time, the researchers ...

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 ...

ACES will gather ultra-precise data across at least ten observation windows, each lasting about 25 days during the ...

Physicists are reshaping our understanding of black holes in new research that maps theoretical structures within them known as “supermazes.” ...

During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String ...

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 back ...
