Time travel is possible though laterally, meaning you’d jump timelines instead of going back in time in your own static time line. I base this hypothesis on proven mathematics and empirical evidence. Through studies of my own and those of my colleagues. 2nd, believe what you want but I will be literal, you cannot die, yes call me a fake, a heretic, blah, blah however most of you cannot prove or attempt to refute it using your own intelligence without resorting to the “good book” (I use the term loosely) anyway you cannot die, it’s simply the law of the infinite multiverse, the bodies we occupy act as nodes, physical anchors to space time that basically lock “you” into incarnate form. When one of these nodes dies or is destroyed that energy evaporates from the quantum state microtubles in your brain and like a cosmic cell tower instantaneously carries that energy to an existing node “you” versions of you that that exists in parallel simultaneously, you will assume the timeline as if you’d always been there. However not even nature in its purest form is perfect, defects occur and the transfer is incomplete, causing people to believe they woke up in a parallel universe (they did) with recollections of their old lives where they worked or people they knew that may not exists in that time line. Anyway I know it’s difficult to believe however, nature is a mysterious beast, no one knows quite why this is, why we need these bodies or even the purpose of them to even exist at all, we suspect the driving force behind existence is its link to infinity without the ever expansion of probability which forms the infinite multiverse in every possible state, time would collapse on itself. Just think of a car on a road without a destination, if there was such a destination expansion would not be possible and eventually everything behind you without brakes will come crashing down on a cosmic scale. There is a theory of why this is, we nick naked it the meta verse theory or the great container, the main universe that houses all universes, like a macroverse of sorts. Even then, does it end? Are there infinite metaverses that house endless variations of universes unknown to anything humans know? That is the most enigmatic question in science.
