This is an example they give of how a paradox will resist being created:<p>> In the coronavirus patient zero example, you might try and stop patient zero from becoming infected, but in doing so you would catch the virus and become patient zero, or someone else would. No matter what you did, the salient events would just recalibrate around you. Try as you might to create a paradox, the events will always adjust themselves, to avoid any inconsistency<p>Could this hold true if it's something more public? Like the classic time-travel idea of going back to kill Hitler? That's such a global, public and world changing event that surely it can't just be somehow absorbed.
