I would say they're two sides of the same coin. The time it takes for light to travel the universe (which makes communication even with nearby stars essentially impossible) is what makes the universe huge.

Luckily FTL communication isn't actually impossible and special relativity only applies to energy and mass.

    I can't tell if you're joking or if you know something nobody else does.

    As far as I know, anything going faster than the speed of causality violates causality. So what are you talking about?

      But we don’t know that casualty is a law of physics, do we?

        Only inasmuch as we don't know that gravity and the Strong Nuclear Force aren't.

      Don't conflate causality and special relativity.

      SR breaks down at both ends of the spectrum, at the event horizon of black holes and in Bose Einstein condensates. That proves that it is an emergent property of observations, statistical behavior of decoherent systems, and not a universal law.
