Title: 7 Black Holes And The Curvature Of Space Time
Course: Relativity > Section: Module 17: 7 Black Holes And The Curvature Of Space Time

7. Black Holes and the Curvature of Space-Time

Explanation:

Black holes are regions in space where gravity is so strong that nothing, not even light, can escape. According to relativity, mass causes a curvature of space-time, and this curvature affects the motion of objects.

Example:

When stars come close to a black hole, they are influenced by the curved space-time around it, which can cause them to spiral into the black hole or be flung away. This bizarre behavior illustrates the connection between mass, gravity, and the geometry of space-time.

These subtopics provide a foundational understanding of relativity, enabling students to explore the fascinating interplay between space, time, and gravity.

Quiz Questions

Sure! Here are three multiple-choice questions related to key subtopics of ‘Relativity’ suitable for beginner students:

### Question 3: General relativity primarily addresses which of the following topics?

A) The behavior of particles at atomic scales.
B) The curvature of spacetime due to mass.
