Newton's Law of Universal Gravitation is written as: \(F=G\frac{m_1m_2}{r^2}\) The constant of proportionality is the universal gravitational constant ("big G") which equals \(6.674\times{10^{- 11}} ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...
