TED-ED: The fundamentals of space-time: Part 3 - Andrew Pontzen and Tom Whyntie

The video explores the relationship between gravity and space-time, highlighting how gravity affects the motion of objects by curving space-time. Einstein's theory of general relativity is compared to Newton's, showing its superior predictive power in certain scenarios like Mercury's orbit and light deflection. The concept of gravitational waves is introduced, with ongoing experiments to detect them. The video concludes with the challenges posed by black holes and the need for a new theory that incorporates quantum mechanics.

In what way does Einstein's theory improve upon Newton's explanation of gravity?

What challenges does the text mention regarding the understanding of black holes?
