DSE with ‘Cameras’ near the Slits

Why would the interference pattern disappear when we ‘look’ at the Photons?

When scientists put some detectors near the slits and tried to observe through which slit each photon was actually going, apparently the wave pattern disappeared and particle pattern emerged. This lead to another mind blowing conclusion of QM: When photons are not observed, they behave like waves but when someone looks at them they behave like particles.

How can we explain that? i.e. why would the wave pattern disappear when we place ‘cameras’ near the slits and try to observe the photon’s path?

Basically the appearance of wave pattern or particle pattern in DSE is not an all or none phenomenon. Depending upon the set up of the experiment, we may get a purely particle pattern or a purely wave pattern or a combination particle and wave patterns. And neither the wave pattern is specific to waves nor the particle pattern is specific to particles. It all depends upon how we setup the experiment!

By doing some adjustments in the experimental setup, We can make water waves produce particle pattern and also make light waves produce particle pattern

How to make waves produce particle pattern?

Decrease the distance between the source and the screen
2) Make the slits narrow and deep
3) Increase the distance between the slits
4) Bring the detector screen closer to the first screen
5) And last but most important, decrease the sensitivity of the detector so that it only senses and picks up the strong impacts and not the weak impacts

And if we do that, surely water waves will produce particle pattern and even light will produce particle pattern. i.e only two bands come up on the screen. Also increasing the intensity of light beam will also change the pattern that appears on the detector. i.e wave pattern gives way to ‘particle pattern’.

Observing the photons’ path by keeping some sort of detectors near the slits alters the slit configuration (i.e it narrows/ deepens the slit) and hence the appearance of particle pattern. We don’t have to resort to absurd and mythical notions like photons knowing and changing their behavior when someone observes, ‘collapse’ of wave function etc.

Now, How to make particles produce wave pattern?

Do exactly the opposite
1) Increase the source to the screen distance
2) Make the slits wide and shallow
3) Make the slits closer to each other
4) Take the detector screen farther away from the first screen, may be to the infinite
and last and most important- Make the screen highly sensitive i.e. it must pick up even the most subtle impact.

if we do that, we can make even our water particles to produce wave pattern outside the water environment. Even bullets, foot balls etc would produce a wave pattern.

So how the detector screen feels something or what pattern the detector screen shows depends upon the set up of the experiment and its sensitivity. Quantum physicists are right here in a way, the same thing may appear as a wave or as a particle depending upon the circumstances and how we look at it.

So waves can be seen behaving as particles and particles behaving as waves.
And that begs the question: Are they both different at all? Are there really two things called waves and particles in Nature? Now we are getting closer to the Truth and able to smell the Non-dual Nature this Creation.

True, there is only one thing. At the most subtle level, that exists as waves and at the gross level, the same manifests as material objects or particles. We may see a ball here. But it is actually a wave in the ether ocean at a more fundamental level. While the gross material form of the ball exists at just one location, its subtle wave form exists all over the space.

    An experiment to prove that electron particles do not exist:

    There are no “particles” in light. Or in any other radiation.
    The “strikes” on the screen are NOT representative of a little ball hitting that spot.
    Once that particular light sensitive area of the detection screen absorbs enough energy from the smooth and continuous radiation, it shows up as a spot. These experiments are not “firing” individual particles, they are firing bursts of energy.

    No one on this planet understands how light actually works, they only understand what it does under different conditions.
    But there is no accurate explanation of the mechanism of light.

    And its a stretch of credibility to say that matter is just energy, this is a religious concept, not science.

    The light is NOT making either a wave pattern OR a particle pattern. Its only making an diffraction pattern, caused by the lenses and mirrors.
    The exact same patterns can be made with just one light source, and a threaded bolt, or a comb or a string of beads, anything like a that.
    The famous M&M iinterferometer is NOT producing any pattern from light “interfeering” with itself.
    This is a huge mistake that needs to be rectified in physics.
    This means that the LOGO detector is NOT detecting minute changes in length of the two arms. Its all smoke and mirrors these days in Physics.

      mark, in the double slit experiment there are no lenses or mirrors, yet there is a diffraction pattern. How do you explain this?

    There seems to be a great emphasis on who can offer some explanation, and the one with the nicest explanation automatically wins.
    But what say we observe some phenomena, and its weird. Then after ages, one person has an explanation. His explanation becomes the default. Because there is no other option.
    For a long time, the default explanation for tricky things was, “God did it”.
    But I think that in many cases, the only correct answer must be, “We don’t know”.
    None of the proffered explanations is really very good.
    Also keep in mind that even a totally wrong hypothesis CAN make reasonably accurate predictions.

    As for light interfering with itself, I don’t ever see this occurring, and ive been watching light for 65 years. Not once has two beams of light interfered with each other.

    In fact, even given billions of light sources, the evidence is that NONE interfere with any other.

    Star light remains individually in tact.
    The billions of sources of direct ajd reflected and refracted light I see as I walk to the shop, remains individually distinct. No hint of light being able to interfere with it self.
