Physicists Say We Were Completely Wrong About How Gravity Works

A theoretical proposal published in the journal Reports on Progress in Physics is making some bold claims about our previous understanding of quantum physics. Mainly, that we were wrong. The proposed theory grapples with the fact that quantum mechanics (basically modern physics) and general relativity (Einstein's theory of gravity) both describe the universe perfectly, but are mathematically incompatible with each other. To make them work, the proposal suggests scrapping almost everything we think we know about gravity, as Live Science explains. Instead, the authors touch up the theory to match known and observable physics, something they call unified gravity. Although quantum field theory — the framework explaining how subatomic particles behave — is one of the most accurate theoretical concepts of all time according to theoretical physicist David Tong, it still leaves out classical gravity, which we know as the bending of space-time. Instead, unified gravity assumes gravity is ma ... Read full article.
