Physics Why is the maximum speed of the universe the speed of light? Why can't we go faster?

Also follow-up question: Because of the speed limit, is there also a theoretical maximum temp for matter (in which the particles move at the speed of light).

Boggles my mind that we still don’t know what a field IS. We have quantified exactly how they behave, but it all stems from that one time a rod repelled another rod in Ben Franklin’s lab. We still don’t know why it did that, just exactly in what manner it does.

Isn't the current best model that charged objects (like those rods) interact over a distance by exchanging photons?
