Dear steemit and steemian

In this post , i wanna share article about Time and 4 dimensional space is there?I will explain this theory below from a trusted source.
Almost all understand that the space we live in this dimension three. The direction of dimension, or axis, can be distinguished as front-back, left-right, and top-down. In the geometry of space, dimension or axis are also called coordinates. Usually given x notation for the left-right axis, y for the front-rear axis, danz for the top-down axis.
We are free to move on these three axes, whirling around at will if nothing is in the way.

Many have also realized that the dimensions we experience are not just three, but four. The other axis is time. Usually notation t.
Among those who are already aware of this, most assume dimensional time dimensions altogether from the three dimensions (x, y, z). The reason, we do not have freedom on the dimension t. Time can not be explored as we go through space x, y and z. We are caught in time. We can only flow with it in one direction, toward the future. Based on common sense, almost everyone thinks that time flows at the same speed for everyone in all places. An hour for you equals an hour for me, for everyone. And it's all for the future. Time can not back down. We are all together being dragged by time.
The time that has passed is a memory, good or bad, and the time to come is wishful thinking or hope.

Time will remain as a memory and hope in the absence of Einstein which gives the formula that space and time are actually interconnected, and a unified coordinate system. This is actually the concept of Hermann Minkowski. Minkowski said: "Actually, if there is only space, or time alone, both will decay into nothing more than a shadow. If both are fused, then there is the reality "(Henceforth, space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality). James Clerk Maxwell, Henry Poincare and Hendrik Lorentz also contributed to Einstein's formulation.

It is Maxwell who wrote the electromagnetic wave equation, in which there is a constant, which is then realized as the velocity of electromagnetic waves in the vacuum. This constant is now called the speed of light c.
Einstein postulated that c is a constant (velocity) that can not be surpassed by anything, either in terms of (particle) or not (photons, information). Not that speeds with numbers greater than 300,000 km / s are forbidden, or meaningless, or nonexistent. The consequence of Edwin Hubble's findings is that the farther the galaxy of the earth the faster it moves away from us, has the consequence that there is a galaxy, because it is so far from us, that its speed in avoiding us transcends the speed of light. That is, this galaxy we can not see until whenever, because the signal will never reach the earth until whenever.
