The Novikov self-consistency principle, also known as the Novikov self-consistency conjecture, is a principle developed by Dr. Igor Novikov in the mid-1980s to solve the problem of paradoxes in time travel. Stated simply, the Novikov consistency principle asserts that if 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.

Rather than consider the usual models for such a paradox, such as the grandfather paradox in which a time-traveller kills his own grandfather (and, thus, prevents his own birth), Novikov used a mechanistic model which was more amenable to mathematics; a billiards ball being fired into a wormhole in such a way that it would go back in time and collide with its earlier self, thereby knocking it off course and preventing it from entering the wormhole in the first place.

Novikov found that there were many trajectories that could result from the same initial conditions. For example, the billiard ball could knock itself only slightly astray, resulting in its going into the past slightly off course, which winds up causing it to knock its past self only slightly astray; this "sequence" of events (actually a causal loop) is completely consistent and does not result in a paradox. Novikov found that the probability of such consistent events was nonzero, and the probability of inconsistent events was zero, so no matter what a time traveller might try to do he will always end up accomplishing consistent non-paradoxical actions.

Largest crowd I've ever seen gathered in Cardiff... all watching the Grand Slam on an outdoor screen. Amazing atmosphere.
