The Speed of Light Changes the Structure of Causality of Space

If two events are not inside each other's light cones, then their order is not well defined. And it is all because the universe has a speed limit. If you shot death rays in every direction, and the speed of light was much smaller, then you would kill a smaller fraction of the universe. Or if you shot joke rays, ou make a smaller fraction in the universe laugh. It really changes everything. We don't know why it is what it is. Our laws of physics just have like an empty spot there.
