String Theory is a theoretical framework in physics that seeks to explain the fundamental nature of particles and their interactions by modeling them as tiny, vibrating strings.
The Multiverse is the hypothetical concept that there are multiple universes beyond our own, each with its own set of physical laws and properties.
In String Theory, there are 10 dimensions - 3 spatial dimensions (length, width, and height), 1 dimension of time, and 6 additional dimensions, which are thought to be curled up and hidden from our perception.
String Theory is considered a theory of everything because it attempts to unify all known fundamental forces and particles in the universe into a single framework.
Currently, there is no concrete evidence supporting the existence of String Theory or the Multiverse. However, scientists continue to research and explore these concepts through mathematical models and experiments in hopes of finding evidence in the future.
