What I have never understood about the observer effect, is how it applies to the observation of blackbody radiation.
For example say we observe the photons emitted from the sun discreetly on earth, how does that alter the state of the sun itself?
- zmmz 14y agoYou have not disturbed the sun. You have disturbed the photons. You disturb the thing that you are measuring, not the source source "higher up the foodchain".
- wamatt 14y agoYeah, that makes sense. Which is why it could also be problematic, if taken out of a QM context and applied classically.
