Observer effect in the Dual Slit experiment

Click For Summary

Discussion Overview

The discussion revolves around the observer effect in the dual slit experiment, focusing on how detectors or observers influence the behavior of electrons or photons. Participants explore the implications of observation on the experimental outcomes, the nature of entanglement, and the speed of information transfer in quantum mechanics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants question whether detectors or observers disturb the electrons or photons in the dual slit experiment, suggesting that this disturbance may change the final results on the screen.
  • Others propose that the detector becomes entangled with the electron or photon, implying a complex interaction rather than a simple disturbance.
  • A participant seeks clarification on how detectors work and whether mere observation by a human can influence the results on the screen.
  • There is a discussion regarding the speed of information transfer between particles in the context of the EPR paradox, with some participants questioning if it could be infinite.
  • One participant asserts that observing light with one's eyes would prevent it from reaching the screen, suggesting a physical impossibility in seeing the results while observing.
  • A later reply criticizes a referenced video as misleading and emphasizes the importance of understanding quantum mechanics through credible sources.

Areas of Agreement / Disagreement

Participants express differing views on the nature of observation and its effects on quantum systems, with no consensus reached on the implications of entanglement or the observer effect.

Contextual Notes

Some claims depend on interpretations of quantum mechanics that may not be universally accepted, and there are unresolved questions regarding the mechanics of observation and entanglement.

How detectors/observers in front of each slit works , does it somehow disturb with electron/photon?
Does photon/electron must pass through detector/observer, so maybe his internal parts change final result on screen into just two lines?

No, the detector gets entangled with the electron/photon.

Can you exlain how detectors work?
If I just observe light that pass throug two slits with my eyes, will electrons show two lines on back screen?
How can my thoughts change reality,results on back screen?
 
Does information travel at higher speed then light between two particles in EPR paradox?
Infinite speed?

No. Google for “no-communication theorem”.

That is physically impossible. You only see light if it enters your eyes to be detected by the photosensitive cells in the retina, and if it’s doing that it’s not reaching the screen.
 
And since this video is garbage and not even close to an acceptable source under the forum rules this thread is closed.

You cannot understand QM by watching stuff like this, you can only accrete misinformation that you will eventually have to unlearn.
