Answer:-
String theory is a theoretical framework in physics that suggests the universe is made up of tiny, vibrating strings instead of point-like particles. These strings exist in multiple dimensions beyond the familiar three of space and one of time. The theory aims to unify Einstein’s general relativity (which explains gravity) with quantum mechanics (which governs tiny particles), potentially leading to a "theory of everything." While mathematically fascinating, it remains unproven since we lack the technology to test it. If true, it could reshape our understanding of the universe, from black holes to the fundamental forces of nature.
