Right. Yeah. And some mathematical models of faster than light travel suggest that traveling at non-relativistic speeds itself creates causality violations, effectively creating a situation where, from certain perspectives, you could arrive in your destination before you left, or receive a message before the message is sent. Which, you know, we can arguably resolve through a preferred frame conceptualization of non-relativistic physics. Or maybe you're creating a new branch every time you hit warp 5.
The alternate realities by way of timeline branches was more or less confirmed in our world, at least with respect to the multiverse. Although the theory doesn't fully account for every reality in the omniverse, which includes at least a handful of universes made by a bored gay teenage wizard. From what I understand.
Wielding the power of the gods is really not all its cracked up to be.
