### Reality FPS. The granularity of the time.

So this post will calculate theoretical minimal time length that is required to render the physical universe.

You see, if universe is guided by laws of physics and physics is guided my mathematics, then there has to be smallest unit of space and smallest unit of time, in order to render the universe. Why, you ask? Otherwise it's getting very complicated if you can scale things down indefinitely. And as for what we know, universe in it's nutshell is simple and elegant. That being said, you can imagine 3d world around us being composite of tiny 3d cubes, each of which containing binary or composite value, meaning that we don't know if it's 0 (zero) / 1 (one) , or a set of variables (a,b,c...n). But that's ok, if we don't have to know precisely, because we can still calculate minimal time length.

In each iteration over time you make each tiny cube interact with all neighbor cubes. As they do interact, they change themselves and other cubes around it. This way you get 3d world with time in it. Things move, interact and change over time. Like the universe as we all know it.

Let's continue our reasoning further. Planck in 1900 calculated minimal possible space volume that can contain a value. It's much, much smaller than a size compared to a proton. We don't know if he is right, but that seems to be consensus among scientist community today.

So if speed of light (3 * 10 8 m / s) is the fastest possible speed, and Planck length (1.62* 10-35m) is the smallest possible space length then it means there are 1.62 * 1035  tiny elements in 1 meter, or 1.62 * 1035 * 3 * 108 = 4.85 * 43 elements in the distance light can travel in one second. In order for light to make it, universe must be rendered 4.85 * 43 per second.

So here you have it. Universe is rendered at 4.85 * 43  frames per second.
