Hey, in &quot;I don&#39;t know physics&quot; language, what happens with observer experiments where there are multiple observers who don&#39;t communicate? Is it possible to get a superposition thingy that collapses into different states for different observers? I&#39;m just curious, not planning to build a particle accelerator or anything.

(don't post a science question after you've spent two days being rude about science, maybe, Marc?)

@quietmarc I don’t think there can be multiple observers for the same observation. Depends on how you define “observation” or “measurement” tho, which is not something there’s consensus on btw. As in, physicists can’t really agree on what counts as a measurement.

@quietmarc The simple answer is no. If the first observation returns some value, then the system has been collapsed* into that state, and the next observation (within a short amount of time^) of the same quantity will necessarily also have the same value. *I use the problematic word "collapse" here without necessarily endorsing Copenhagen lol ^there are subtleties here that require adding "within a short amount of time" but that doesn't really change the answer imo
