Transcript
in 1915 a German scientist sat quietly calculating mathematics which would revolutionize how we look at the universe his discovery would describe black holes and describe a new way of looking at space but it wasn't Albert Einstein he was surrounded by the sounds of artillery fighting in the first world war this video is brought to you by brilliant ...

Questions & Answers
Q: How do black holes generate such strong gravity that light cannot escape?
Black holes generate immense gravity due to their density, bending the spacetime grid described by general relativity, preventing even light from escaping.
Q: What was Einstein's contribution to understanding gravity?
Einstein's theory of general relativity replaced Newton's gravity model, describing gravity as the curvature of spacetime due to mass.
Q: How did Karl Schwarzschild contribute to understanding black holes?
Amid World War I, Schwarzschild solved Einstein's unsolvable equations, deriving the Schwarzschild radius to define black hole size and characteristics.
Q: Why is it significant that Schwarzschild found answers during war?
Despite the chaos of war, Schwarzschild used math and physics to explore the unknown, demonstrating the power of human curiosity in challenging times.
Summary & Key Takeaways

Black holes are incredibly dense objects with gravity so strong that not even light can escape.

Einstein's theory of general relativity replaced Newton's theory, explaining gravity as the curvature of spacetime by mass.

Karl Schwarzschild, during World War I, solved Einstein's equations to describe black holes and their Schwarzschild radius.
