GRANDFATHER PARADOX : A PARADOX???

Novikov self-consistency principle

Whatever is done in the past can never alter the future in any mannerParallel universes /Alternate timelines

Every decision you make has a consequence

NOVIKOV SELF-CONSISTENCY PRINCIPLEIf an event exists that would give rise to a paradox, or to any "change" to the past whatsoever, then the probability of that event is zero

According to this hypothesis, the only possible timelines are those which are entirely self-consistent

Anything a time traveler does in the past must have been part of history all along

The time traveller can never do anything to prevent the trip back in time from being made since this would represent an inconsistency.

In layman's terms, this is often called determinism. It conflicts with the notion of free-will.

If time travel is possible, then actions are determined by history.
