In principle nothing prevents the different interpretations of the same data at speeds greater than light
Causality in general and and Lorentz symmetry in particular prevent it. Information may not propagate superluminally.

Later,
It is by no means obvious that the observers in motion may be equivalent to observers at rest. Once you recognize this possible equivalence, you may postulate a Galilean symmetry. Then you may look for classical deformations of this group. You will only find a few examples and the Lorentz group is the only one that makes the speed of light finite and universal.
Nevertheless, the Galilean group is a special example in which some commutators (of the boosts) are set to zero. This choice may be obtained from the Lorentz group by setting the defining speed - which is called the speed of light - equal to infinity; the Galilean group is a contraction of the Lorentz group. On the other hand, the speed of light is finite in relativity which allows one to unify the space and time; to unify electricity and magnetism; to identify the mass and energy by Einstein's most famous formula. The Lorentz symmetry also severely constrains the possible forms of the physical laws.Wavefunction collapse into an observable is
instantaneous over arbitrarily large distances and volumes, as empirically demonstrated by the Bell Inequality in the Einstein-Podolsky-Rosen paradox. It conveys no information until collected datasets are compared - and that is limited to lightspeed.
Relativity has c=c, G=G, h=0 as boundary conditions. Quantum field theory has c=c, G=0, h=h as boundary conditions.
May be using wirtual particles because virtual particles can travel at speed greater than speed of light.
Wrong. Horribly, ignorantly, dysfunctionally wrong.
Am I not the greatest Sceintist?
Idiot. By what lunatic hallucination of credulity does poster "dkv" rate four stars?
