The Geometry of Space-Time: Unifying Dimensions and Rotations

TLDRSpace-time unifies space, time, and motion in a geometric framework. It consists of abstract rotations called Lawrence Transformations. These transformations allow for changes in reference frames, preserving the speed of light and the geometry of space-time. Special relativity explains the relativity of motion and the concepts of acceleration, electric and magnetic fields, momentum, and energy. General relativity extends this understanding to include gravity. The true nature of space-time at the fundamental level is still a subject of exploration.
