In the context of relativity, dimension refers to the number of independent directions in which movement is possible. This means that in a 3-dimensional space, movement can occur in three separate and independent directions. In Einstein's theory of general relativity, space and time are merged into a single four-dimensional space-time, which means that movement can occur in four independent directions.
