we can't even know what is and isn't because knowledge itself is just a concept fabricated from our brain machine.
Even if it was, that doesn't matter.
The universe is only as big as you think it is.
Speed of light law just has to do with our basic physics laws. If the foundation of our universe was changed slightly, physics would have different laws and the speed of light may be different or it may not exist at all. It just says that matter cannot travel faster than or at the same speed as this. If it did, it wouldn't be matter anymore. Some research has been done about forces potentially communicating faster than the speed of light (forget the name but if two atoms have the same electron path, then you move them farther away and change it, the other's will change at the same time, or something like that) but we know gravity doesn't, so it seems unlikely that any would.
And yes, reason governs this universe. So there is a reason, but it may not be as exciting or thought-provoking as you want it to be. It could just be that space is just that big. It could be that matter has only drifted so far into the void. It probably doesn't have anything to do with our wants/curiosities.
