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 radius?1916
2. What is the discoverer?Karl Schwarzschild
3. What is the formula?Rs = 2GM/c²
4. How do scientists find the Schwarzschild radius?They use the formula Rs = 2GM/c², where G is the gravity constant, M is the mass, and c is the speed of light. Plugging in the numbers gives the radius.
5. What happens if an object is inside its Schwarzschild radius?It will inevitably collapse into a singularity and become a black hole. Nothing can leave once it crosses this boundary.

Event Horizon: The boundary in spacetime beyond which events cannot affect an outside observer; the point of no return.
Schwarzschild Metric: The exact solution to Einstein's field equations describing the spacetime outside a non-rotating, spherically symmetric mass.
Spacetime Singularity: A point in spacetime where the laws of physics break down, often associated with black holes.
Escape Velocity: The minimum speed needed for an object to escape the gravitational influence of a celestial body.
