General Relativity
General Relativity redefines gravity as the curvature of spacetime caused by mass and energy.
π My Interpretation
I see it as a rule of motion written into space itself. Instead of a force pulling objects, it's geometry guiding them. Everything tries to follow the straightest path possibleβbut those paths are curved when space is bent.
π Key Concepts
- Geodesics: The natural paths objects take in curved spacetime.
- Time Dilation: Clocks tick slower near massive objects.
- Black Holes: Not just dense matter, but places where spacetime itself caves in.
- Equivalence Principle: Free-fall and no gravity are locally indistinguishable.
General Relativity replaces force with shape, and rewrites how we understand motion at every scale.
