It gets worse extend that thought if you did multiple observations you would sap energy out of the object wouldn't you ... hold that thought we will come back to it.


I can see that in the case of Haroche’s experiment, “observation” would take energy away, but does that necessarily imply that all observation extracts energy. E.g. I am looking at a computer screen, observing words on a page. If I close my eyes I stop observing. Is any less energy being remover from the screen/computer just because I close my eyes?

There never was nothing.
