Double Slit Experiment explained! by Jim Al-Khalili

What is the emitter aiming at when a photon is fired? Do photons move in perfectly straight lines? Could a photon hit and then bounce off of the inner surface of the slits? Is the detector emitting anything that could interfer with the photon passing by. Does turning off the detector change the environment? What material is the slit made of? Do different materials yield different results? Does air have any effect on the photons? What happens if this experiment is done in a vacuum? Does the wavelength of light emitted make any difference to the outcome? Just a few questions raised by this video.

Terrifying. Not sure why the audience was giggling their way through it

How is this even possible?
The only way i can imagine is that everything has already happened and it is being played back to us.

Insane how people accept this with laughter ……. That means something going on Wake Up!!!!!!

Conciusness interfere with reality

As commented by some, I think what we perceive as atoms (just like electrons) may exist in a quantum cloud that's governed by higher-dimensional laws than we can detect. However, our detecting equipment may cause some tiny variations in those dimensions that account for this behavior. Figuring that out is obviously non-trivial, but imo that's where the answer lies.

It's not the size of your particle beam that matters. It's if you can trigger the colapse of her wave function 🌊

Like the photon it's simply is a wave interference with the others and interference with the slit it self like resistance causing change in wave pattern

The atoms know when they are not being onserved.

I think the problem is that we observe with our eyes/brain , which are really just ATOMS.

atoms observing atoms........ there must be something to this

I'm thinking the experiment is wrong

10 years later and I finally get it

I think you've missed a trick there Jim.

You start by saying that you need a specific light to get it to produce light and shaded strips. Yet when you turn it on its side you drop your particles using gravity producing a couple of piles of particles.

I don't think that this is a fair representation of particle behaviour through the slits.

I think that you need to have a more uniform type of particle, and you should also increase the velocity of your particles too.

Unfortunately I don't have the time or resources to conduct this experimentation myself. However I believe that you would see a marked difference if you can vary the particle/velocity ratio to an optimum ratio.

"Quantum Spatiomorphosis Field"

Dark energy can warp spacetime, just as it causes acceleration of massive stars into the night. When photons decide paths, such as in the double slit experiment, the wavefunction is rejoined and does so in distinct geometry. When corrupt wavefunctions are absorbed by a translucent material the material corrects the wavefunction. Corrupt wavefunctions can correct the past via observation... A dark energy wave from an object makes the object look more distant, from all angles. Also the object can only be interacted with via accident unless correct spacetime geometries are known.

You said Noble Prize

Well I can explain

What you are seeing
Is what the Eye can not pick up

But the Camera can

The camera can see plasma and Radiation

It that simple

sorry. dipole particle

so light is a particle that presents a wave. so what?

i really have the answer, it is really dumb 😂

Where exactly is the stream of atoms aimed in the double-slit experiment? Toward one of the slits? Between the slits?

I understand to a degree. I have a lot of questions which don’t matter. Like what kind of an atom is being shot ? Do other atoms behave the same? What happens if you leave the camera but it’s not on?

Just try it

Once aware, the results CHANGE.

Not as bad as the permanently damage your daughter experiment

😟😟😰😩😩😰😟😰😩😧😧😦😧😧😳😵😶😳😳

How on earth after all those years after the first experiment, and 10 years after this video posted, none from the academic community brave enough to admit the obvious, that the detector interact with the electrons producing different results.
Also, almost no one talks about the detecting device or methods. None questions the method and the conclusion of the experiment.
It's all told as vague as possible.

Watching this video is more understandable than reading the book 😅

This was not really an explanation , just stating results from experiments. What would ne the detector pattern be if one slit is closed and the have the wave is going through the one open?

I bet it was the beep the camera made.

what would happen if you use a device which emmits Xray only instead of a measurement device after the slit, would it make a difference if it is on or off as far as there is no measurement device?
if the result is the same when the xrays are emmitet or not , (as far as i understand the measurement device uses xray), that would be unbelivable.....

The detector absorbs the extra photons or atoms. Please send me my Nobel Prize. Thank you.

Dreadful explanation

I have been amazed by the double slit experiment for as long as I can remember, but I would like to know more about how a device can shoot out a single photon/electron and have it detected. Why can't I find any video of someone doing this experiment? I'm not a conspiracy nut, but it seems like such an easy experiment to reproduce, but I have never seen it.

I would like to request a Nobel prize with my finding below:
I can explain why light and matter can satisfy the seemingly-incongruous classical definitions for both waves and particles in double-slit experiment.
Light is an electromagnetic radiation with magnetic field. When it spreads out in particle with magnetic field as wave, it forms several bands on screen.
However, the magnetic field is affected and disappeared with an observer aside so that only two bands are shown.

It gets even weirder when they did the delayed choice experiment.
He explained it wrong, the first pbservation of the atoms was from before they passed the two slits. The delayed choice experiment want to observe them after they passed through, but before they hot the screen. They emitted waves, they passed through as waves, and the instant the choice was made to observe them, they behaved like particles.. and even weirder..even though they emitted waves, they recorded themselves as having passed through the semsors as particles. They went back in time and altered their state. So, they tried it with waves of light from a galaxy 100 million light years away, and those waves too changed to particles. Turn the sensors off? Its a wave again. The observer changes the behaviour of the atoms. Kind of like how video games are rendered.

Best explanation of double slit experiment on all the tubes of internets - right here

He mentioned that the spacing has to be right without mentioning what that spacing was. The answer is they have to be one wave length of the light being used. Using the matter-antimatter model of a photon, it becomes possible for the photon to pass through both slits. Further we know that photons can interact with each other. Incoherent light spreads, coherent light doesn't. As far as the atom experiment, he again doesn't explain the separation of the slits. Like a magician, we cannot examine the trick or slight of hand. Not very scientific.

Can someone explain to me what would happen if the detector in this experiment was connected to to a counter that was inside a black box where the outcome could not be observed. What pattern would result. If it is still an interference pattern, then would happen if the black box was opened and the counter observed at a later date but before the pattern on the screen observed, what would be the result of a later observation of the screen?

Do what?

This was explained very poorly

It's not the particle knows it's being detected or not. It's the future connected to the present happening simultaneously. Setting a dector interferes the future, which also reflected on the present.

You just made 3d images of the experiment and didn't do the experiment itself?

Consciousness does not live in the arrow of time but the all. Emotions live in the arrow of time hence Ying and yang. So when I observe and collapse the wave function I do it in the all not in the arrow of time.

Why is this not in the forefront of everybody's mind? This experiment keeps me up some nights

Thank you. This is the clearest explanation I have come across.

That's like the guy who dipped his balls in glitter. That's pretty nuts

So, the atoms are aware if being observed. If they are aware they have consciousness and therefore we live in a virtual reality. What is the problem?

The detector is emitting atoms that the fired atoms can detect. Simple!

Show us in real time.. how do you even shoot an atom???

Has anyone done the double split experiment with the detector being either powered on or off by a random number generator with nobody knowing its state at the time?
