Can Past be Predicted?

This is in continuation with the previous post. Please have a look at it before continuing with this one :). Here, I will be assuming some things. One is that future cannot be predicted exactly, as no one has looked at it before, and according to Heisenberg's theory, it cannot be evaluated until someone has watched it. So, if we cannot predict the future precisely, can we predict the past?

Past events have occurred and have definite values with them. For example, on 1st October at a specific location, a particular event occurred, it cannot be changed. Now, can be find out what happened at past? Here is a nice experiment that I have been giving some thought.

"Given a particular chess game position and the number of moves played, can we precisely determine what moves were played by the players to arrive at the current configuration on the set?"

Give it some thought? What say? Will elaborate on my solution in next post.

Can future be predicted?

I don't know :P. Well, but recently heard Heisenberg's uncertainty principle being applied to programming world (can't remember what was it exactly, but its about some variable whose state is not known till its value is read). Can this principle be applied to future prediction. Here is is the theory, the more ahead in future you try to predict, the less the probability of the event occurring. So, the difference of time predicted times probability of event occurring must be constant (and probably may be equal to h - Planck's constant, no proof yet :(.)

(delta) T * (delta) p = h

This leads to the corollary that at a given moment, you can predict exactly what is going to happen the next moment.

Now, here is an interesting argument. Given that we can determine what is going to occur immediately next moment, we can use that data to predict exactly what is going to occur the next moment precisely. Continuing in the same fashion, we can determine the future at any instant of time.

Confused? Well, I am too :P. Any comments to prove my theory wrong?
