[Terminator] At the end of 2, the T-800 blows up Cyberdyne and John destroys the Skynet progenitor CPU. That's essentially the T-800's version of the Grandfather Paradox, where he goes back in time and kills his "ancestor", thus making his creation impossible. How did he do that?

Time travel in the Terminator universe follows the ”alternate reality” trope. The T-800 clearly exists in its home timeline, and that timeline continues to exist alongside the one where it does not exist.
