special relativity - Do we know why there is a speed limit in our universe?


This question is about why we have a universal speed limit (the speed of light in vacuum). Is there a more fundamental law that tells us why this is?


I'm not asking why the speed limit is equal to $c$ and not something else, but why there is a limit at all.


EDIT: Answers like "if it was not.." and answers explaining the consequences of having or not having a speed limit are not--in my opinion-- giving an answer of whether there is a more fundamental way to derive it from law to explain this limit.
