The gravitational constant, which was first used in Isaac Newton's laws of gravity and now an essential part of Einstein's field equations, describes the magnitude of the gravitational force ...

The Gravitational Constant: The Gravitational Constant has a value of 6.67384x10^-11 m^3 kg^-1 s^-2. Now, this possibly looks a bit messy but it basically means that gravity has a set strength.

Once again, physicists have confirmed one of Albert Einstein's core ideas about gravity — this time with the help of a neutron star flashing across space.

You have to remember that back when Einstein was working on a theory of gravity to replace and supersede Newton’s law of universal gravitation, we didn’t yet know very much about the Universe ...

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.

Astronomy Einstein's Gravitational Lenses Could Clear Up Roiling Debate on Expanding Cosmos News By Charles Q. Choi published 12 September 2019 ...

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 ...

Time, as we experience it on Earth, may not be as constant as we imagine. According to Einstein’s theory of general relativity, time is not uniform across the universe; it’s actually affected by both ...

All of Einstein’s theory had been proved except for the presence of gravitational waves, but that all changed Thursday. “It’s mind-boggling,” Reitze said.

Einstein's theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings.
