Well, not quite. I can think of at least one other thing that is faster than light that occurs naturally.
In the ream of quantum mechanics at least there appear to be influences that do travel faster than light and perhaps even instantaneously. See “EPR Experiment”, “Belle’s Theorem” and/or “non-locality”.
There are also hypothesized particles known as “tachyons” that supposedly travel faster than light. Einstein’s theory never actually ruled out objects traveling faster than light. Rather it states that objects with mass could never be *accelerated-to* the speed of light, OR slowed down to the speed of light IF they had already been traveling faster than light via some mysterious process. For them to do either would require an infinite amount of energy, at least according to relativity theory.
