Timepass timetravel

Yesterday Pradeep showed me a book that was real cool. It was on "infinity" the holy grail of maths ..and somehow we got reading  it and came to a part on Godels Proof of incompleteness of the scientific knowledge. Although frankly I could not get far on the "I am a liar" statement…We got discussing on the fact that weather time travel is possible theoretically.

 

What is the paradox involved?

 

Suppose I go to the future and see the events and then come back and alter the present. What would happen to concept of free will then? Or lets say I go back to the past and kill my father.. will I exist then?

 

I feel that such paradox can be avoided if we take into account "information storage" mechanism. Lets say brain..or it can be any arrangement of molecules..say a beta tape, an audio tape or cd.

 

Now when we take the "memory" through time…we inexplicably alter it instantaneously . For example say memory(it could be a person ..or a camera). Starts at 8 Pm from space location A . It has travel through the red line to B (B is future….say 8Pm  tomo). In all the travel it has gained information..ie the state of memory has changed in one direction.

 

Now when it comes back to today (ie A) at 8 pm, it has theoretically two states ..

 

1. Without information ie..befor it left
2. With information ie.  After it has come back

 

Such dual states are the true nature of  paradox.

We discussed two ways of avoiding the paradox

 

One(which I suggested) was that upon coming back(the green line) the memeory devices "undoes" what it has learnt as it is traveling thru negative time gradient. Hence it returns to the same state it was ..so there is no duality . Essentially it's the same as goin to loot a bank and losing the money on the way …u return home in the same state that you were..none richer or poorer.

 

Second(Which pradeep suggested) was that on return path the "memory" gains more and need not necessarily go to the same spot ie. A but to a parallel spot A'(shown by a straight green line) which may be spacetime removed. Much like robbing a bank and making it to page 3.

 

Which actually means that there are "slots" existing in our part of universe for parallel happenings. Maybe that's what is meant by "Probability" the fact that a thing doesn't happen only means probability is low ..it can happen. Maybe such parallel slots are those spaces where those events can happen.

 

Come to think of it ..there are points of control systems where there is an equal chance of the sysyetm swinging either way. Why does it swing one way preferentially can only be attributed to chance.I feel in another parallel slot (ie A'B') the other "Swing" happens.
