Morgan Freeman = BEST NARRATOR EVER!

Brings new meaning to the old question, "if a tree falls in the woods and there is no one to hear it, does it make a noise?"

@gitaarman1956 good observation

'observe' is the key factor in all this

[MrBij010]

the people commenting on this video are way more intelligent than I am holy shit

[NizzBomb69]

orrrrrrrr maybe our ideas of what photons are is completely wrong...?

[gitaarman1956]

It's a bit like leaving home with the bedroom window open and a shower rained in and wet the sheets on my bed. Now I'm not stupid and after I put cleandried sheets on the bed I observed while a single drop of rain came through the window to see where it falls. Why didn't it wet the whole sheet? I was completely boggled by this. What is rain? Is it a raindrop, or is it part of a shower? And how can the raindrop fall exactly on a single spot on my sheets? As if it knew it was being watched.....

[gitaarman1956]

OK, here is the truth about the double slit experiment: It's an illusion. An electron particle never has a steady position in it's wave. It might travel al over the universe with incredible speed. But once you observe it, it's position is determained and with that, it's path. You now know wether it will travel through slit A or through slit B and not through both. Now if you don't observe it, it's path is not determained and therefor it will behave like a wave and travel through both slits.

People (scientists too) also tend to misinterpret why a single photon shot one at a time causes an interference pattern. The explanation is really plain and boring. There is an interference pattern because its not just one photon being shot one at a time. There just isn't a way to shoot one photon at a time. Photons can't be said to be exactly here or there. You can only give a probabilitv distribution that its here or there. So you can't say that its 100% sure that its one photon only.

[Judas1of12]

People misinterpret this experiment all the time. There are actually 2 totally different experiments going on and that is why you get 2 different results. You have 1 experiment without detectors, and you have a totally different one with detectors used, The mistake is thinking that the second experiment is the same experiment, only we're observing the path of the photon. When you added the detectors, it changed the experiment. Its now a different experiment with a different result.

@ewanstanley

I think that's the logical conclusion everyone came to

[Robological]

@UnitedCorpOfAmerica

I guess it if there's no one there to hear it...it doesn't bother to fall at all. Or exist.

[ewanstanley]

Has anyone ever suggested that the detectors are physically affects the photons when it "watches" them? Perhaps some kind of interference?
