Why is there a universal limit on the speed of light?

As a researcher in theoretical physics, I'm probing the foundational axioms of our universe. This isn't just about the "how" of the light-speed limit, but the "why" behind it what principle of reality enforces this boundary? It's crucial for my work in quantum gravity to grasp if this limit is a geometric constraint of spacetime itself or an emergent property from something more fundamental.

That's an excellent question that gets to the heart of modern physics. I've found it helpful to think of it not as a "speed limit" imposed on objects, but as a fundamental property of spacetime itself. In relativity, the speed of light isn't just about light; it's the conversion factor between space and time in the geometry of the universe. If something could travel faster, it would break causality the principle that cause must precede effect leading to logical paradoxes like influencing your own past. So, it's less of a barrier and more the very speed of causality, woven into the fabric of reality to keep it consistent.
