In physics, the definition of time is simple— time is change, or the interval over which change occurs. It is impossible to know that time has passed unless something changes. The amount of time or change is calibrated by comparison with a standard. The SI unit for time is the second,...
speed of light - the speed at which light travels in a vacuum; the constancy and universality of the speed of light is recognized by defining it to be exactly 299,792,458 meters per second light speed, c constant - a number representing a quantity assumed to have a fixed value in a sp...

General Relativity remains valid even with a varying Speed of Light and also Quantum Mechanics is unaffected.Paul SmeuldersSutton Courtenay现代物理(英文)P. Smeulders, "Why the Speed of Light Is Not a Con- stant," Journal of Modern Physics, Vol. 3, No. 4, 2012, pp. 345-349. doi:10.4236...
to equate to 90 degrees, and similarly the speed of light is agreed (not measured!) to equate to 299792458 meters per second. The agreed value of speed of light, combined with the definition of the second, results in an unambiguous unit of length. In other words, by defining the unit ...
It moves at the speed of light, still. The reduction in the y-direction, in this frame of reference, is a consequence of the Lorentz transformation, which can be viewed as a consequence of the constancy of the speed of light. Of course you can notice that if the motion in the y dire...
