Observer effect in the Dual Slit experiment

In summary, the conversation discusses how detectors and observers in front of each slit work and whether or not they interfere with the motion of electrons or photons. It is mentioned that detectors can become entangled with the particles, and that observing light with the naked eye is physically impossible. The topic of information traveling at faster speeds than light is also briefly mentioned, and it is advised to avoid relying on unreliable sources for understanding quantum mechanics.

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.
