Big Bang
Even brilliant minds can cling to comforting ideas. Truth does not care what we prefer. It simply waits for evidence. Fred Hoyle meant “Big Bang” as a jab. The universe turned it into a headline.
Relativity
Einstein-based spacetime, gravity, and motion.
Spacetime as geometry.
Classical physics describes motion, energy, and interaction through continuous systems and deterministic laws. From Newtonian mechanics to thermodynamics and electromagnetism, it models a world where causes produce predictable effects. It remains the foundation for engineering, planetary motion, and everyday physical intuition.
