Relativity (Special, and General) explained, including the first two experiments that have so far verified the theories:

The how and why remained to the domain of what is called general relativity, a complete theory of gravity using the geometry of spacetime. The origin of general relativity lies in Einstein's attempt to apply special relativity in accelerated frames of reference. Remember that the conclusions of relativity were founded for inertial frames, i.e. ones that move only at a uniform velocity. Adding acceleration was a complication that took Einstein 10 years to formulate.

Problem?
Both general Relativity and Quantum mechanics (Copenhagen interpretation) cannot be correct. But they have both been experimentally verified to accuracies of greater one part in 100,000, the limits of our technology....(and the math?)
The search for TOE continues :O)
