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.
