Time Series Analysis, Predicting Future...

The other day i was reading Time series Analysis and hence gave inspiration to this thought!!
Rather silly and funny.. nevertheless worth mentioning.. :P

If we count time since the earth began in seconds it grows and continues to grow every second...

Now, 
If we take inverse of this time, the series converges. Hence it is analytic.
Hence limit exists for such a series.
Hence any formula used to predict the future using this has a finite and definite value..

Hence you can predict future precisely! :)

  1. Or rather, our future events are precisely specified now, and cannot be changed in the future, when it is happening. Since it cannot be changed, future cannot be predicted at all!

    How about that? :-D

  2. The catch is that you cannot count precisely!! Quantum mechanics dictates precision and nothing is infinitely precise.

  3. Dude.. Your logic was right till half way.. the conclusion however didn't fit.. As we can precisely specify what can happen.. we CAN predict future,given a good formula.
    As such a formula can be designed to give a stable answer at all points in time except time t=0 as you cannot invert it!! Strangely you can even specify what will happend at t = inf.. :P

  4. @Vatsa: I dont intend to count precisely...
    While you integrate you just need a start time and end time.. Integration takes care of everything in between... (btw assuming that such a formula will have an integration or for that sake any well defined mathematic operation)

  5. @RB: Suppose you find out what can happen in the future and you take steps to make sure it wont happen that way, then your formula will be invalid right?
    I am not saying that such a formula doesnt exist...I am telling that as long as you are part of this system (read: universe), you cannot find out that formula imo.

    Yes you are right.. we can predict.. not change.. and the formula i am talking about is just a predicter.. not corrector...

  7. Acc to what you have said, limit exists for the inverse, but not for time. I don't know (rather, I forgot) the mathematics of this, but if a limit exists for a function, can we conclude that limit exists for its inverse as well?

  8. @Shreays.. No.. limit need not exist for the inverse..
    Ya.. Im waiting for a future predicting formula which uses inverse of the time and not the time..

  9. Flaw 1: Provided you have a formula which uses this inverse you can predict future perfectly. But unless you have one you can't make state the theorem :P

    Flaw 2: Time is not absolute, but relative. Parallel universes exist where you may meet yourself in another time like "Grandfather paradox (check in wiki). So time is no more a single dimension quantity :D

    That doesnt make sense...If you can predict, then what stops you from changing it? If i find out that i am gonna die after 2 years, i can kill myself today and change it!!
    Or i can save someone's life...
    Dont tell me universe corrects itself because of the changes you make....It will be one of those 'Final destination' movies we watched that night...Remember, sushmith?

  11. My remark to santhosh is we are just Mute Spectators of this world(though philosophical yet true :) ).. what is happening was known and what will happen is known!!
    That is why we do not have a formula yet..

  12. @Vinay that paradox states
    * Negative time travel is not possible due to paradox itself
    OR
    *An independent timeline exists.. which does not alter the current events(events in this timeline) so it still holds..

    I did not make it a theorem.. but thanks for giving it such a status :D

    Based on our 'Big Bang' discussions, any predictor that can be built will give wrong predictions, since our future is already decided and we can't change it. If a true predictor is built, then we have the ability to change the future - which is impossible :D

  14. @Shreyas: No. Future is already decided doesnt mean that the predictor will give wrong results. It only means that any predictor built at any point of time (1400 AD or 2000 AD) will predict the same result.
    But its true that such a predictor cant be built, since it will give us the ability to change our future.

  15. if this is an artificial world(Matrix).then as told in the movie by oracle : future is already decided.we are here only to understand our choices that we have made.. every person can see the future only to some extent,to the extent he can perceive things. you cannot see things beyond the thoughts and questions ur brain( or code) cant think of ;)..thts why neo can see trinity falling from building and I can c myself as a successful engineer..lol

  16. I go by Neo.. Ops Smith.. :P
