Predictions

This is probabably more of a sci-fi geek-out than a note-worthy issue, but it's interesting to me, so... yeah.

Our perception of time, as mentioned in a previous post, determines our entire concept of logic and thought process. One of the things that is inherent in our perception of time, and also the foundation of many of our standard modes of thinking, is the relationship of cause and effect. We think of virtually everything with regard to this process, and it allows us to understand the ramifications of everything we do and witness.

Generally we think of the past event as the cause and the future event as the effect. The intesting reality is that each event is both. We only label things the way we do because of their order of occurence in time. When a jug of milk is spilled, we assume that the normal state of the milk was not spilled, and that the spilled state is the effect or result of some action. It is just as possible to see the natural state of the milk as being the spilled version, and seeing the resulting non-spilled milk as the effect or result of an opposite action.

Then it gets a little tricker. The result of thinking about this is to say that the natural laws push things in the direction of spilling, but not in the opposite way. This is also simply a matter of perspective. Gravity is reversed in its effect if time is perceived in reverse. Entropy, or the natural tendency toward disorder, is reversed. Magnetic poles are reversed. The strong and weak force that bonds subatomic particles together are actually reversed as well as the electromagnetic force that we normally think of repelling or attracting charged particles.

All of that is simply a way of thinking about something from a different perspective. The more interesting thought is that if prediction works one way, it could work the opposite, since they are essentially the same. We can generally predict the results of standard physical interactions using the normal rules. We just have to reverse the rule expectations and work the equations in reverse using the current situation as the result.

I really have no idea how that actually works, but it seems like there is something interesting in it. I will have to think more about the possible ramifications of it.
