Lesson 1: Introduction & Fundamentals
Objective: Understand the basic concepts and nature of black holes.
Content:
– Definition: A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape from it.
– Key Concepts:
– Singularity: Center of a black hole where the mass is infinitely dense.
– Event Horizon: The boundary surrounding a black hole, beyond which nothing can escape.
– Types of Black Holes: Stellar, supermassive, and intermediate.
Resources:
