The fabric of space-time combines the three dimensions of space with the fourth dimension of time. Space-time explains the unusual relativistic effects that arise from travelling near the speed of light as well as the motion of massive objects in the universe. This is a vast field of physics and theoretical physics. We needed the work of several physicists including Newton, Maxwell, and Minkowski to lead Einstein towards his special relativity and general relativity theories. According to Albert

The fabric of the cosmos explained simply.
