If higher dimensions exist, they aren't what you think - Exploring Worlds Beyond Our Own

The video explores the concept of gravity through Einstein's general theory of relativity, which describes how mass bends space-time. It introduces Kaluza-Klein theory, suggesting a fifth dimension to explain electromagnetism. The video delves into higher dimensions, using analogies like Flatland to illustrate their implications. String theory is discussed as a potential unifying theory, requiring extra dimensions for its mathematical framework. Despite the lack of experimental evidence, these theories offer intriguing possibilities for understanding the universe.

What are the four fundamental forces of nature, and how does string theory aim to unify them?
