Updated this article with some more clarity. Now this explains why, time acts like a mediator between orthogonal variables such as x-space and y-space, so that, x-y are unified to time and together are equivalents. Time is thus the parameterization, between physical variables that represent the orthogonal dimensions of space.
It gets mixed like a messenger to every dimension, so as to keep a count of the total amount of the dimension, that has emerged, in essence therefore, speed is the ratio of this amount of space-dimension to time parameter, and speed-of-light is 1, when its merely a single photon in vacuum, or a condition that its energy and momentum are equal, suitably adjusted for the units, hence a special mass-less particle thats a wave by its own nature, or a wave-nature particle, (like a good-nature boy).
An important lesson of Relativity.

An insight of why time and space are equivalents or unified in Relativity. Because its time which makes it possible for someone to crawl from x point to a y point, you can’t simultaneously move bifurcated, into two orthogonal axes. Time mediates, hence its the time axis that mixes with all of the space axis, x, y, z. (Just came across this idea, originally I wrote in July 2012, and seems a bit non-trivial to share)
An important lesson of Relativity: you can’t go from x to y or y to z or z to x or z to y. They are perpendicular … But you can go from x to t and then t to y. In effect you can go from anywhere to anywhere else, because there is anytime.
Relativity has limitations though. Also Limitations are not to be confused with Laws of Nature or Physics, which are valid restrictions. So Anytime means anytime with restrictions and limitations.
Imagine an x-axis point (x, 0) slipping back in through, to your joint, than your joint moving up there. Then this point is now, (x, t). While that was happening, the point (y, 0) also kept on moving towards your joint, to reach your damn thing, in time t, (y, t). (x, y, 0) evolved to (x, y, t) and you didn’t do a thing, x, y, just met. At t = 0, x, y were on different axis, at t = t, they are at the same point. Thats how you moved from (0, 0, 0) to (x, y, t), Cool ?
