This is only loosely related but I thought you might be interested in a new paper, just described[1] by Sabine Hossenfelder. They started with the assumption of a multiverse, and said that we're most likely to find ourselves in a universe that has physical constants allowing for the most observers. They checked such a constant, and found that the constant is nowhere near the ideal; if it had been different, there would be a lot more planet-bearing stars in our universe. They claimed this as evidence that the other universes don't exist. [1] https://www.youtube.com/watch?v=IXzV7zdl4oU https://www.youtube.com/watch?v=IXzV7zdl4oU
