# Causality without light

Related to my prior question: Would a species insensitive to light have developed special relativity?

Imagine a species insensate to light and other em radiation. They are very attuned to sound however. Might they conclude that any transmission of information faster than sound violated causality? For example, a bullet impacts a person, then a second later they hear the sound. Might this situation suggest to such a species that causation had been violated?
