Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. Who discovered Schwarzschild metric?1916
2. What is the discoverer?Karl Schwarzschild
3. What is the theoretical significance?First exact solution to Einstein's field equations, foundational for black hole physics
4. Why is the Schwarzschild metric important?It lets scientists calculate how planets move, how light bends, and even predicts black holes. It shows that outside a round, non-rotating object, gravity depends only on its mass.
5. How does the Schwarzschild metric explain black holes?When a mass is packed inside its Schwarzschild radius, the metric shows a point where the usual coordinates stop working. Inside that radius, nothing can escape, creating an event horizon.

Spacetime Interval: A measure of the distance between two events in spacetime, invariant under coordinate transformations.
Coordinate Singularity: A point where a mathematical coordinate system breaks down, not necessarily indicating a physical singularity.
Gravitational Lensing: The bending of light by gravity, causing distant objects to appear distorted or magnified.
