everything that is possible happens. That means that when you flip a quarter, it comes down heads and tails. Not heads or tails. Every time you flip a coin and it comes up heads, you are merely in the universe where the coin came up heads. There is another version of you out there, created the second the quarter flipped, who saw it come up tails. Every second of every day, the world is splitting further and further into an infinite number of parallel universes, where everything that could happen is happening.
