Hyperspace is a theoretical concept in physics that refers to a space with more than three dimensions. In this context, it is often used to describe a higher-dimensional space that can help explain complex phenomena in the universe. The idea is commonly explored in science fiction, where it allows for faster-than-light travel and shortcuts through space. In the realm of theoretical physics, hyperspace is sometimes associated with string theory and M-theory, which propose that additional dimensions exist beyond our familiar three-dimensional space. These theories aim to unify the fundamental forces of nature and provide a deeper understanding of the universe's structure.
