Special relativity says that the temporal order in which events happen can () depend on the frame of reference of the viewer, and thus, such events do not have any objective order in which they occur. () that is, if their relative "time-position" is spacelike, or in other words, if light is "too slow" to travel from one event occurring to the other event occuring. To add on top of this, it says that if faster-than-light particles exist, a chain of FoRs can be constructed such that an event happens before itself. If that isn't shaking basic principles, I don't know what is.
