    Double slit Slit
Click For Summary
The discussion centers on the implications of detector interactions in the double-slit experiment and their role in wave function collapse. It is clarified that the presence of which-way information, even without recording, prevents the emergence of an interference pattern due to the interaction with the detector. The conversation also critiques Tom Campbell's theory that reality is based on information and suggests that his proposed experiments may not align with established quantum mechanics principles. Participants emphasize that the collapse of the wave function is tied to physical interactions rather than the mere recording of data. Overall, the consensus is that understanding these interactions is crucial for grasping quantum mechanics and its implications.

Using my mentor superpowers to reply to a closed thread, I would like to point out that the experiment
Nugatory said:
I would find it very difficult to respond to someone who challenged me for experimental evidence that Earth's gravity exerts the same force on one kilogram of cold-rolled 1045 steel alloy as on one kilogram of 1018 steel alloy.
is carried out every day in constructions sites all over the planet. If there was a significant difference in gravitational acceleration for different materials, architects' and engineers' calculations would be off and no skyscraper would stand up.
