Four Fundamental Forces Defined
- The universe operates through four fundamental forces: gravity, electromagnetism, strong nuclear, and weak nuclear forces.
- These are the irreducible interactions that govern particle and matter behavior.
Gravity as Spacetime Curvature
- Gravity is the weakest fundamental force but acts over infinite range and always attracts.
- Einstein explained gravity as spacetime curvature caused by mass and energy.
Electromagnetism Unification Explained
- Electromagnetism is much stronger than gravity with infinite range, acting between charged particles.
- It unifies electricity, magnetism, light, and chemical bonding, described by Maxwell's equations.
