Curves Quote by Brian Greene
“Einstein comes along and says, space and time can warp and curve, that's what gravity is. Now string theory comes along and says, yes, gravity, quantum mechanics, electromagnetism - all together in one package, but only if the universe has more dimensions than the ones that we see.”
About This Quote
Source Book: The Elegant Universe by Brian Greene, 1999
Gravity is described as spacetime curvature, and string theory aims to unify forces by proposing extra dimensions beyond our perception.
In simple terms: Gravity bends space; string theory adds hidden dimensions to unify forces.
