Dude Einstein theorized a hell of a lot and proved little to none of his work. I think you should stop talking about any hard science, because you are generalizing and talking about things second hand of which you have no comprehension or understanding.
No offense, but Einstein stated that matter could not be created nor destroyed, but he also did not believe in the idea of simultaneity. Meaning that two actions happening at a distance with no direct interaction could in fact have equal and opposite reactions through spintronics. The idea of information transmission in the t/pt dimensions is through simultaneity/spintronics. Meaning, no useful matter can be transmitted or information that which is not already known in the future verse. All this says is that if we were to rig an experiment were we did the same quantum operation on the exact same particle in two separate times, there's a chance that it would react from the simultaneous experimentation. But that would pre-suppose knowing about the future experiment in the past.
It's a paradox, and Einstein came up with lots of them. They're just brain twisters, nothing more.
Einstein did not believe in time travel. If your chemist prof seems to think so, he's full of ****.
IE, he's full of himself and thinks highly of himself because he works at a community college, but all the while, he's a complete and utter ideot, because those that do DO, those that can't, teach.
If he had half a brain he'd be doing research at a major university.
