Here’s a good example of uncertainty. During the 1/320th of a second that this picture represents, the batter has simultaneously hit a homerun and struck out. Because the event that determines which path he follows hasn’t happened yet, we can suppose that both outcomes are true. Once we hear the bat or the glove, the outcome is set, and the other reality falls away. Some speculate that all those unused realities don’t really “go away”, but create infinite parallel universes. That’s a little too much to read into a high school baseball game, though.
Turns out, he got a standing double… and they won the game 9-1
