> which assumes that it is not possible to exceed the speed of light. That's... No, that's not what General Relativity says at all. The speed of light as universal speed limit is not a postulate, it is a result. The reason is because going faster than light would break causality, as I mentioned, meaning time travel, and therefore meaning all kinds of paradoxes. That is why it is generally said that FTL travel is impossible; because the consequences of it being possible are absurd.
