okay so i think ive got a decent scientific question for you guys. and ive been thinking about it for some time. so im gonna define some terms to help:

is causality luminal, or superluminal?
to preface this. i mean causality itself independent from the practical physical constraints of our universe. i dont mean necessarily interactions of light and matter and their speeds restricted by Einstein's law, but the phenomena of causality itself. what do you think? because it seems to me that what somebody would call causality being sub-luminal is more the case of information being sub-luminal.
