I know that the past, future and present can occur simultsneously someplace at some velocities that gives predestination some real estate. Depending on how you slice space time one would be looking at a past or a future but not be present in either. Being human I can relate to premonition as a real quantum phenomenon with more ease. Going back in time is a real no-no in my book. There are some things for which I can not suspend belief. A work around by using coded communiction by entangled particles are still a cheat. Authors that treat realities in physics too fast and loose fall short in my reality models. Popular now is the 20 year old multiverse idea. It too makes for a cluttered mess in my way of thinking.

I've even tried ideas of entangled twins going into opposite time streams but that too was cheating by ignoring paradoxes.
Some travel should is simply best not tried.
