Minkowski Spacetime

Minkowski spacetime is a mathematical framework used in special relativity that combines space and time into a single four-dimensional continuum. Instead of thinking of time as a separate entity, Minkowski showed that time is intertwined with the three dimensions of space. Events in this spacetime are defined by their position in space and their time of occurrence. The geometry of Minkowski spacetime reveals how objects moving at high speeds experience time differently than stationary observers, highlighting the relativity of simultaneity and the effects of time dilation and length contraction, which are key concepts in understanding the universe's structure.
