Faster than the speed of light can move, for example, the phase of oscillation. This does not contradict general relativity, and it is impossible for a mass body to move faster than the speed of light, because an infinite amount of energy is required to be imparted to the particle.

Limiting the speed of movement of material objects by the speed of light (c) is a property of our 4-dimensional space-time, where we all live, and our entire Universe is with us. This very strictly follows from the definition of the 4-speed (u) in the Minkowski metric, where || u || ² = u ⋅ u = ± c². Even to approach the speed of light is possible only for elementary particles. The maximum energy achieved today in collisions of proton beams at the LHC (CERN) accelerator is 13 Tera Electron Volts (TeV), which corresponds to the relative proton velocities of 0.99999999⋅c. In cosmic rays, proton energies of ~ 2 × 10⁸ TeV are recorded, corresponding to proton velocities of 0.99 ... 999⋅c (23 nines in total). The mechanism of acceleration of particles in the Universe up to such gigantic energies (speeds) is still not clear. In relativistic mechanics (or in our Universe), only massless particles (a photon, for example) are allowed to move at a speed equal to the speed of light (s).
And what laws of physics in Futurama or in the stories of science fiction writers depends only on fantasies of the authors.
Travel above the speed of light was in many fantastic works, and in some places it was not even badly explained.
How possible is it? With a very high degree of probability. To deny this possibility is completely foolish. It's just that our current knowledge and technologies have not reached this level, and the future is in the fog of progress. So far, all that remains is for science fiction writers to throw ideas to scientists.
