Thomas Young's double slit experiment 2.0

Clip from Cosmos Possible Worlds on National Geographic

Reality is more astonishing than fiction...this is amazing

[TheRustyMooseForLife]

This brings the old say 'if a tree falls in the woods and nobody is around to hear it, does it make a sound' to a whole new level.

[Endless]

Yeah I think God's gotta patch this bug in 2030.

I don't think the question should be "how can a photon know if someone's watching?" It should be "why would it care?"

[TairyHesticles]

This is the single greatest experiment ever conducted.

[Malitubee]

Neil Degrasse is so charismatic, I swear this guy makes things so interesting

[Crazias]

hope i live to see the day this gets explained

By observing the photons, or not, you are affecting the past.
If you are in the room, we might be talking about one, one hundred millionth of a second, so you don't perceive it.
But if someone is doing the double slit experiment five light years away, and we see it in a telescope, we are affecting something that happened five years ago.
Mind boggling.

Thank you for posting a video about this experiment that actually makes sense

[AshishMishra-obnk]

Thanks for uploading this. Was looking for this particular clip.

The mere act of observation changes reality 🙌

[tristanparrish]

Maybe this also involves the simulation theory in that the simulations do not process what is being observed in the same way that it is when it is not being observed in an attempt to save processing power.... When we don't observe the outcome, the simulation is not as precise leading to the interference pattern.

[Vulcain-wetw]

If only those Phd's scientists asked the YouTube section for info, they would know that it was the detector that was interfering with results

You people shuld check the "delayed choice experiment"

[eziowayne]

This video makes it seem like observation (i.e. by a conscious observer) is what weird effects the experiment. However, it is simply the measurement which causes the photons to behave differently since in order to make a measurement, you must interact with the photon. Consciousness has nothing to do with it

[mrpogz]

I wonder what happens if they turn on the observer camera but cover the lens.
Is it possible that an electronic device was near the slit and it somehow changed the wave or behavior of photons?

[orangelimesky]

This means there's a lot more going on around us, when we're not around. When we're involved, time goes slower, things move slower to but when not involved and you're just going with the flow, time suddenly goes faster, and a lot of things suddenly start happening... Something about our involvement slows other things down. Definitely something there with what reality actually is.

[anthonyharris]

Once you get this concept in your brain your reality will change guaranteed.

[midnightrider]

So if a particle event depends on an observer, perhaps what is happening is not to be questioned but rather can an observer actually comprehend what they are observing at the quantum level. Perhaps other dimensions in space-time come into play in a way we cannot observe with our limited observation tools.

[richardhedd]

this begs the question, what is it about the observation process that changes the outcome?

I never understand this when i was studying this young s double slit experiment in 11th grade 16 years old at school and i was sooo furious at myself for being so stupid not understanding this ….but i dont mind not understanding this, i have got my inner peace after watching this even though i don’t understand anything
