I wish I could answer this, but as previously stated, any question which concerns something that has never been observed is fit for a philosophical or religious discussion. Physics can not add anything to those conversations.

Nothing has ever been observed that moves faster than the speed of light. Well, kind of.

If you point the beam of a flashlight at a wall, a slight rotation of the flashlight can cause a large move in the location the beam strikes the wall. The spot on the wall can move faster than the speed of light, if the wall is sufficiently far away. However, the signals (light beam) which produce the spot do not travel faster than the speed of light. Similarly, a shadow can move faster than the speed of light.

There are other examples in which some observed phenomenon appears to violate the cosmic speed limit. However, appropriate applications of the theory of relativity can always demonstrate that none of these phenomena are capable of carrying information faster than the speed of light.

*note the use of the word information in this context means ANY measurable connection between the prior and subsequent states in the apparent violator.

The spot on the wall does not carry the information from the flashlight, the beam carries the information, and the beam does not violate the speed of light.
