The Search for Elusive Gravitational Waves

The video discusses the nature of black holes and their gravitational pull, which even light cannot escape. It highlights Einstein's theory of relativity, which predicted gravitational waves. Despite many of Einstein's predictions being proven, gravitational waves remain elusive. Engineers are developing a system using satellites, known as Lisa, to detect these waves. The satellites will form a triangular formation, orbiting the sun, and use precision lasers to detect changes caused by gravitational waves.

What is a supermassive black hole and where is it typically found?

How did Albert Einstein's theory of relativity change our understanding of physics?

What are gravitational waves and what causes them?

What is the purpose of the Lisa satellites and how are they designed to detect gravitational waves?

Describe the mechanism by which the satellites maintain the internal detector cube's position.
