🕳️Understand Black Holes Without Spaghetti Confusion

Rethink black holes as curved spacetime — not cosmic vacuum cleaners — using thought experiments, scale comparisons, and the geometry that actually traps light.

Phase 2The Event Horizon, Mapped

Map the boundary where light gives up

5 drops
  1. The event horizon is a speed limit, not a wall
