Why this formula appears here
Here is exactly where the analogy earns scrutiny rather than deference, because it also shows where it breaks. The atoms discarded by the trap unambiguously existed a moment before, in the same room, on the same table, measurable by the same experimenter had they been fast enough to catch; there is no dispute about their reality or their number, only about whether they were selected into the sample. A universe with different constants that nobody observes has no such settled status — whether it exists at all, in what sense, and how to count it relative to ours (the term in the expression above, the number or measure of observers a given value of produces) is…
