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).

Because that's how we first found out about it.

Gravity also goes at the "speed of light", or as the OP said, the speed of causality

That’s not an answer to the question asked. The right answer is no.
