Tenet Explained By a Physicist

Ever heard of Feynman’s theory of antimatter: that it is matter travelling backwards through time? Know our current understanding of time? What about whether entropy and time are related? Can you reverse entropy? Does reversing entropy cause time to reverse? How about the many worlds interpretation of quantum mechanics? Then check it this video, because you’ll need to know most of this stuff to understand Tenet! Rather than explaining the plot I explain several theories in physics the movie assumes correct
