1. Einstein's theory of general relativity describes gravity as the curvature of spacetime caused by mass.
2. The famous equation E=mc^2 from Einstein’s special relativity shows the equivalence of mass and energy.
3. Einstein predicted the bending of light by gravity, which was confirmed during a solar eclipse in 1919.
4. His theories have been essential in understanding black holes, where spacetime curvature becomes extreme.
