INSIGHT

Origins of Black Hole Theory

  • Mitchell and Laplace first theorized black holes via escape velocity exceeding light speed.
  • Modern black holes form by crushing matter into a tiny space where light can't escape.

From Theory to Observation

  • Early physics doubted black holes formed in nature despite solutions in relativity.
  • Observations later confirmed stars collapse into black holes, proving theories right.

Event Horizon’s Time Mystery

  • Event horizon marks point where escape even at light speed is impossible.
  • Time appears to stop at horizon from outside view but passes normally for falling observers.
