Sign in to savestandard and classical physics theory of gravity and space
AI overview
General relativity is Einstein's theory that explains gravity not as a force, but as the way massive objects curve space and time around them. It matters because it fundamentally changed how we understand the universe, from explaining the orbits of planets to predicting black holes and the expansion of the cosmos itself.

Slow motion computer simulation of the black hole binary system GW150914 as seen by a nearby observer, during 0.33 s of its final inspiral, merge, and ringdown. The star field behind the black holes is being heavily distorted and appears to rotate and move, due to extreme gravitational lensing, as spacetime itself is distorted and dragged around by the rotating black holes.
