+4D refers to the concept of a fourth dimension, extending beyond our perceived three spatial dimensions. It is a mathematical abstraction, often explored in [Physics](/wiki/Physics) to describe an additional spatial axis or commonly interpreted as the dimension of [Time](/wiki/Time). This conceptual space allows for new forms of existence and movement, challenging our everyday intuition.
