Ok, for everybody who is using this as the basis for their understanding of quantum physics, I want to make this clear: the act of observation is not what's magically transforming the results of the experiment. It's because, to observe which slit an electron went through, we have to shoot a photon (light particle) to observe it, and that photon hitting the electron (how we observe it) disrupts the electron's path, which creates a different result. It's not some mysterious force.

@jabe55 Anyway I'm not interested in pursuing this conversation on this video (or any other more likely) because a discussion with deluded Christians doesn't belong here and doesn't interest me.

@chuckpcr That video you pointed to:

/watch?v=LW6Mq352f0E

is simply awesome! Thanks.

@em0rtalitie

I base that part of what I said on your comments. However in the original double slit experiments with single photons they ran the experiment with the photon detectors on and running but did not record and data and they got the interference pattern. This was done specifically to see if the detectors were the cause. They only got to two bands when the detectors were on and they were actually collecting data.

@warren52nz Yes, I have heard of the Shrodinger's cat thought experiment. I've always thought of it as, that since we cannot know for sure which path an electron takes, the wave of probability represents all the paths it might be taking, but is taking only one of the possible paths.

[em0rtalitie]

@chuckpcr what? From my interpretation, what you are saying is that if we shoot a photon at one of the two slits to observe the path of an electron, and the photon misses the electron, the electron still behaves like a particle, instead of a wave, right? I haven't heard of this experiment before :O could you tell the name of it please?

[warren52nz]

@em0rtalitie They say that if you think you understand Quantum Physics, you don't!

Just a statement about how weird it is and how difficult it is to grasp what it says when it goes against our common experience.

"Schrodinger's Cat" is another thought experiment on the same subject. I won't explain it here, you can look it up if you haven't already and you're interested.

The cat in the box IS ACTUALLY alive AND dead at the same time until you open the box, then it's one or the other.

@em0rtalitie " Is there any way that we can measure the path of te electron without it coming into contact with anything"

I don't know maybe not. But the finding isn't about that. This is just 1 simple experiment to show the phenomenon. Further investigations confirm that the act of observing actually nails down all possibilities to one and before the observation all possibilities actually exist simultaneously.

As I understand it. I haven't studied it for over 30 years. It's hard to think about

@em0rtalitie

One problem when the electron is not being observed it exists as wave of probability that allows it go through both slits at the same time. The act of observation collapses wave of probability into one of the possibilities. This is not dependent on shooting a photon at it. For example if the electron goes through the slit you are looking at the photon would miss it and could not collapse its wave of probability, yet the act of observing still collapses its wave of probability.

LOL, and he should learn to spell "physicists". I smell bullshit.

[em0rtalitie]

@warren52nz Is there any way that we can measure the path of te electron without it coming into contact with anything? I believe that the interference causes by any object shooting towards an electron will disturb its path. This is how I have learned it but I, too, am open to ideas that prove otherwise :]

[warren52nz]

@em0rtalitie From everything I've heard (and I did a Bachelor of Science degree in Physics) this experiment (and all others) DOES show that adding an observer collapses the probability wave function into one of the possible outcomes. As far as I'm aware it doesn't matter how you observe or measure it... reality has multiple circumstances until you look at it and then it becomes one of those circumstances.

It's truly that weird. I'm open to evidence to the contrary of course.
