Therefore, Einstein's gravity cannot be the ultimate theory of gravity. ... Here, Λ stands for either Einstein's famous cosmological constant or a mysterious dark energy with similar properties.

In Newtonian gravity, it tells us how two massive bodies are gravitationally attracted to one another, but in Einstein’s theory of general relativity, this constant communicates how anything in ...

Einstein’s earliest formulations of general relativity included a cosmological constant – a kind of anti-gravitational force ...

Albert Einstein’s theory of general relativity has been remarkably successful in describing the gravity of stars and planets, but it doesn’t seem to apply perfectly on all scales.

Albert Einstein’s theory of general relativity has been remarkably successful in describing the gravity of stars and planets, but it doesn’t seem to apply perfectly on all scales.

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

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding ...

Through an effect called gravitational lensing, first predicted by Albert Einstein, a distant galaxy named MRG-M0138 ... Researchers remeasure gravitational constant.

Einstein’s theory of general relativity suggests that our universe originated in a Big Bang. But black holes, and their gravitational forces, challenge the limits of Einstein’s work.
