..what bugs me, is the massive amount of inertia that's got people believing that Light is the fastest thing that there is out there. There's a speed 'C' and nothing can travel faster or it will go back in time. Light can travel that fast, but never any faster. Never ever! I'll probably never be able to explain why exactly it is that this frustrates me, but I'll try anyway.
First off, why does anything travelling faster _have_ to go back in time? Time is merely a concept that we humans have come up with in order to measure duration. Establishing for ourselves, causality and basically, placing eggs before chickens. However, our descriptions of Time are merely superficial. x seconds have passed.. blah blah. But when we get down to it, we have absolutely no way to know what time is. Aside from the basic fact that time is an "idea" that separates events, it is nothing else. Essentially though, it is a _concept_ and as such, has no other value. What is it made up of? Can it be modified or turned into something else? Can you break it up into its component pieces? (I don't mean breaking hours into minutes, and seconds etc. I mean as an entity or something truly physical in nature.) We can't even observe it. We can merely mark its passage by the sequencing of events that happen with its passage.
An effect cannot happen before its cause. That's understandable. However, just exceeding a certain velocity will not cause time to roll back. Or for that matter, to slow down. Ones _perception_ of time might be altered, but time itself does not change. It's all relative.
If you travel faster than light away from an object, your eyes will definitely see events happening in reverse. But that is because you are seeing light that has left the object that it reflected off of earlier and earlier due to the fact that you are overtaking photons as you zip ever onward. Meanwhile, an object you happen to be travelling toward, will have the opposite effect for exactly the same reason, but in reverse. Events occurring at the object will be perceived as happening faster than they actually are. However, Time itself has not changed. Your perception of it, as an observer inside a system might be different, but Time has not changed, gone backward nor forward. Time IS as Time HAS always been. A Concept.
Much like Thunder after Lightening.. We know the thunder was caused at almost the same time that the lightening was created. However, we hear it much later. When a train goes past us, we experience the Doppler effect. To a Blind man, It would seem as if the thunder was all there was and that it was caused at the moment that he hears it. He would have no cause to imagine that it was created at a time before it reaches his ears. It's the same with us and how we perceive photons of light. If we could perceive stuff that moved much faster than photons too, we would measure time using that as one of our indicators of passing events. As humans, we embrace most anything that seems convenient. Not always, but most often anyway. Why are we talking of time moving backward in the first place?
If someone can show me where it is that I'm going wrong in my understanding of this, I'd love to hear your thoughts. This has bothered me for a long time, and I know that I come off sounding silly to most of you who actually understand what I wish I could. However, I'd like to understand what you do, so.. Help? :)
