What is the Novikov Self-Consistency Principle?
The Novikov Self-Consistency Principle states that a closed timelike curve is impossible, because if it were possible, you'd have already done it, and you're not, so... yeah.
It's like trying to unscramble an egg, but with more explosions.
Or, as we like to put it, "You can't unmake the things you didn't make, unless you made them, but only if you didn't make them, and so on."
It's a paradox, folks! A delicious paradox, served with a side of cognitive dissonance.
