  is the speed of causality tied to speed of light in a vacuum, or independent of it?

    As I understand, the speed of light in vacuum is bound by the speed of causality. So, light would go at infinite speed, if it could (it being massless means any acceleration should result in infinite speed), but instead it goes as fast as the universe allows, which is the speed of causality.

    Speed of Causality is the absolute maximum speed. Speed of Light in a (perfect) vacuum happens to be equal to the Speed of Causality.

      Is the speed of causation propagation linked to plank length?
