Space-time and beyond | Open LibraryIn physics , spacetime is any mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams can be used to visualize relativistic effects such as why different observers perceive where and when events occur differently. Until the turn of the 20th century, the assumption had been that the three-dimensional geometry of the universe its spatial expression in terms of coordinates, distances, and directions was independent of one-dimensional time. However, in , Albert Einstein based his seminal work on special relativity on two postulates: 1 The laws of physics are invariant i. The logical consequence of taking these postulates together is the inseparable joining together of the four dimensions, hitherto assumed as independent, of space and time. Many counterintuitive consequences emerge: in addition to being independent of the motion of the light source, the speed of light has the same speed regardless of the frame of reference in which it is measured ; the distances and even temporal ordering of pairs of events change when measured in different inertial frames of reference this is the relativity of simultaneity ; and the linear additivity of velocities no longer holds true. Einstein framed his theory in terms of kinematics the study of moving bodies.
