Many of u know that am a firm believer of causality. I am rather of those who believe every effect has a cause rather than thinking of some absurd destiny. And this is even mentioned in Hindu Philosophy. While i was reading (re-re-re-reading for some articles...) on Wikipedia I once again came across the Grandfather paradox. The key concept of this paradox is

Suppose a man traveled back in time and killed his biological grandfather before the latter met the traveller's grandmother. As a result, one of the traveller's parents (and by extension, the traveller himself) would never have been conceived. This would imply that he could not have travelled back in time after all, which in turn implies the grandfather would still be alive, and the traveller would have been conceived, allowing him to travel back in time and kill his grandfather. Thus each possibility seems to imply its own negation, a type of logical paradox.

Assuming that time travel was made possible..either via some kind of wormhole or following my theory (might b nonsense as hell this is science fiction..)..i managed to travel back in time..and kill my grandfather..what would happen of me?? or better..what if i fathered my father rather than my grandfather doing so?? I would then own grandfather..confusing isn't it?

Anyways..i was actually thinking about time travel..lately i was in a situation where i had to make a choice, one which would decide on the rest of my career..and while i was in a some weird stuff hit my mind..travelling to the future could help me decide what to choose..but how??

What is the present to start with?

According to me..the present is what we can hear, see, feel. Well the present is what we experience through our senses. Those are bounded by the speed of light..and the speed of travel of electrical signals to our brain. Speed of light is basically the fastest speed of travel mankind came across (isn't it?). Now what if it wasn't? This could be distorted..or we could go faster than that (perhaps through a wormhole??). This would mean we are already living in the past..since the events we are experiencing have already occurred..and since our perception depends on the speed of light or speed of electrical signal..we are experiencing it later..

Is that confusing?

Well..thats just what i think..

I also read a lot about parallel universes..i even have a documentary by BBC on the subject. The documentary deals with parallel universes, string theory, M theory, supergravity, and other theoretical physics concepts. Participants include Michio Kaku, Paul Steinhardt, and other physicists. If want a copy just let me know..

    Lol as a Hardcore SF fan meself, am completely absorbed by this article :) (Scientifically as well as philosophically :) )

    And another point to add to what you said, even if you manage to go back and perform some action, it implies it WAS Possible for you to go back anyway, then what proves it was not this way to begin with? Yhat you were not *meant* to go back? (Temporal loop kind of situation)

    sinon, slightly unrelated sidenote, but as we are dealing with SF-like theories which give headaches, hrer for you:

    Or the simplified humorised version here

    Did I read "wormhole"...well guess u got'vet this from stargate.
    Well sometimes today science fiction become tommorrow reality..who know??

    It is all about perception. I like it vry much!! :D hmm u said light travels fastest than anyfing.. faster than our thoughts?! about parallel worlds i've thought about that.. there was a time wen i thought we cud b living in many parallel worlds..
    anyway nice post which makes my thoughts travel a lot!

    not exactly confusing but id say mysterious n dangerous....the truth is out there..but only the time is not right to find out the truth day we shall....but the future is made by choices we humans make..but i i believe that somewhere forces do compel us to make choices...n its commonly known as destiny...or more complex even...GOD....i mean..i think parallel world may exist coz of the theories of universe n all that...i mean if we can exist then why can't there be others??..thk abt it....
