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

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.

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

Einstein published a new theory of gravity—the theory of general relativity—in 1915. It would transform our understanding of physics forever. But it’s far from perfect.

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists ...

A team of scientists compared Einstein’s theory of general relativity with data from the Dark Energy Survey. They found a “slight discrepancy” in the behavior of gravity at different cosmic ...

Einstein’s theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own ...

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 ...

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.
