What is general relativity? Essentially, it's a theory of gravity. The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it. #walsall #fyp #einstein #generalrelativity #spacetime #time #space #facts #spacefacts #universe #spacetok #gravity #physics #mass #warps #science
