Have you ever thought about the fact that the speed of light (and thus the fastest possible propagation of information) is finite? Would a world without a finite speed of light be conceivable or meaningful?

In computer game engines, there is usually no speed of light. In frame A nothing has happened yet, then you pull the trigger and in the next frame the opponent is already hit. The problem: You have to consider the whole world for every frame, because every event somewhere in the world might influence your state, because it doesn't take time to get to you.

Now let's imagine the whole thing with finite speed of light. The following scenario: We are on earth and want to render the environment around us. Again, if there were no finite speed of light, we would have to look at the whole universe and check if any event affects our immediate surroundings. This would be very time consuming. But with finite speed of light we only have to look at our direct environment to render it. So, for example, if a rover lands on Mars and sends radio signals to Earth, we don't have to look at them until they actually arrive at Earth.

Now where is the big advantage of finite speed of light? Parallelism! One can render a scene on earth and a scene on Mars in parallel for a time x, because it is guaranteed that they cannot influence each other.

Whoever has designed this universe, has designed it in such a way that one can calculate it efficiently. We live in a simulation!
