>If we had some way to see the universe at speeds much greater than light, so that the universe, as a whole, could be watched instantaneously, there would be no anomalies. I could watch you traveling at the speed of light as I also observed me traveling an the much less speed of earth as time passed. I would be able to project the universe at a future time based on studies of the current trend in the universe.

>Maybe someone will find a way where we can see the universe without the need for light, which is a poor mechanism to interpret such a vast expanse. For example, maybe someone will find a way to use dark matter, much like we use radar, to observe the universe. This sounds like science fiction, but I think some day it will come to pass.

The Theory of Relativity bases its assumptions precisely on the fact that information has to travel at a finite speed (maximum at the speed of light). Science fiction authors have been thinking of "workarounds" for quite a while; as of yet, everything seems to indicate that the speed of light is, indeed, an upper speed limit.

It is usually believed that if you can travel faster than light, then you can also travel into the past. This has to do with the notion of simultaneity, as defined in the Theory of Relativity: If you have two far-away events, they might seem simultaneous for one observer, one event might seem to happen before another for another observer, and the second event might seem to happen before the first for yet another.
