>This means that if observer A sends a signal to observer B which moves faster than light in A's frame but backwards in time in B's frame, and then B sends a reply which moves faster than light in B's frame but backwards in time in A's frame, it could work out that A receives the reply before sending the original signal, challenging causality in every frame and opening the door to severe logical paradoxes.[19]
How? Even with all these examples provided I still don't understand how tachyons would break causality, how an effect could arrive before a cause just by having signals traveling faster than light.
