Oh ok, I see what you're saying. Still impossible though. Speed is measured in km/h (or mph for all you backward Americans), as I already stated, when something is travelling at the speed of light, time for it stands still relative too all other objects. So it's physically impossible for an hour to pass. Therefore, there is no speed faster than the speed of light, it's a mathematical impossibility.

However there is one exception (although its not really an exception at all). In the time when the universe was 10^-36 (0.(35 zeros)1) seconds old it was experiencing a massive inflationary period (from the size of a marble to a size trillions and trillions of km's wide) where matter in the universe was expanding faster than the speed of light. However, since the fabric of space itself was also expanding extremely fast, the particle were just kind dragged along, never going faster than the speed of light relative to space itself.

I hope I explained that clearly enough...I'm really sick and may not be thinking straight.
