There’s a lot of discussion about “time” in the world of quantum physics. At the micro level, where waves and particles can behave the same, time tends to be much more malleable than it is in our observable realm of classical physics. Think about the clock on the wall. You can push the hands backwards, but that doesn’t cause time itself to rewind. Time marches on. But things are much simpler in the quantum realm. If we can mathematically express particulate activity in one direction, then we can mathematically express it in a diametric one. In other words: time travel…
