Higher-dimensional space

Higher-dimensional space refers to dimensions beyond our familiar three dimensions of length, width, and height. While we live in a world where we can easily visualize these three dimensions, mathematicians and physicists consider additional dimensions that can help explain complex concepts. For instance, in a four-dimensional space, an extra dimension can represent time or other properties. These higher dimensions are often used in theories like string theory, which attempts to describe the fundamental nature of the universe, suggesting there could be multiple dimensions that we cannot directly perceive but have significant implications for physics and mathematics.
