the scientists note that prohibiting paradoxical events would cause unlikely events to happen more often. These “strange and counterintuitive effects” arise due to the nonlinear nature of P-CTCs. Like a movie hero who always manages to escape seemingly imminent death, the grandfather would always somehow manage to survive his grandchild’s murderous plots. “Some little quantum fluctuation would whisk the bullet away at the last moment,” Lloyd explained.
In addition to prohibiting the grandfather paradox, the P-CTC theory also has the advantage that it doesn’t require the distortions of spacetime that traditional time travel theories rely on. These spacetime distortions probably only exist in extreme environments such as inside black holes, making these theories nearly impossible to realize.

I honestly see time travel and time travel paradoxes as nothing more than a cool thought experiment.

when people talk about the paradox of going backwards because of affecting the future etc, I don't get it (I'm not new to the subject) because, for one in quantum mechanics people talk of "the observer" so if something happens to you(the time traveller) it does'nt happen to everyone (the world would be a pretty strange place). theoretical scientists also talk about multiple realities the theory that because we live in an infinite universe perhaps every possibility has happened, so if one was to go back, doing so would surely only effect them they would create a new different line/reality/universe and so it would'nt effect their previous universe whatever, nothing would change there but something would be added to the whole of existense/possibilities. so the grandfather paradox is a misnomer. Hope I've explained my thoughts all right I'm not very good at this writing melarky
