Gravitation: The Four Fundamental Forces of Physics #3

The video tutorial explores the concept of gravitation, starting with an introduction to its role in the universe. It covers Newton's classical theory, explaining how mass and distance influence gravitational force, and highlights its limitations, such as in predicting Mercury's orbit. The tutorial then transitions to Einstein's theory of general relativity, describing gravity as a distortion of spacetime caused by mass and energy. This section explains phenomena like light bending around massive objects and the formation of black holes. Finally, the video discusses theoretical particles called gravitons, which are believed to carry gravitational force, although they remain undetected.

Explain how the concept of spacetime relates to gravitation according to Einstein.

What are gravitons and how do they relate to the concept of gravitation?
