Demystifying the Observer Effect: Neil deGrasse Tyson Explains | Joe Rogan Experience #JRE #919

Join us on the Joe Rogan Experience as Neil deGrasse Tyson sheds light on the often misunderstood observer effect. From particles behaving as waves to the influence of measurement, Neil breaks down the science behind this intriguing phenomenon. Contrary to popular belief, it's not about magic or consciousness but rather the act of measurement itself. Just as light reflects off objects allowing us to see them, the quest to determine the position of subatomic particles presents fascinating challenges. Discover the mind-bending implications of the observer effect and gain a deeper understanding of its role in the quantum world. #ObserverEffect #QuantumPhysicsExplained #NeildeGrasseTyson

The problem with this explanation: Both parts of the double slit experiment (when someone observes the experiment and when no one observes the experiment) are done under the exact same light etc. Conditions.The only difference is when someone makes a measurement there is the presence of the detector and a consciousness.Jim Al-Khalili's video on the double slit experiment verify that the presence of of the detectors alone don't collapse the wave function.Someone has to actually LOOK through the detectors to collapse the wave function.

Notice how this dude only speaks his opinion all the time. NEVER sites studies to back up his nonsense.

[Chemike]

This has been done with blinfolded people imagining they are observing, and you still get the same result. It has nothing to do with light moving the atom.

[The-inspirational-moments]

Because the space you disrupt to observe moves the object as the object is less than the space.

[vendetta]

Whoever or whatever is observing the particle, is the one using light to move the atom. To do any study or experiment is to observe. This very act moves atoms. We mistakenly put too much emphasis on light when trying to understand this. Instead focus your attention on the atom size being less dense than the space it’s in. Even the smallest amount of light used to observe will move an atom. Human eye, animal eye, Camera, anything that uses light to observe will move particles.

Ntd heavily misunderstands the observer effect lol ironic.

Neil was the person who said it on an episode of cosmos. Literally.

[fabioalbastos]

Nice explanation. It's like trying to measure a droplet's temperature with a big thermometer. Since the thermometer needs to gain or absorb heat to perform a measurement, if its mass is to big, it can change the droplet's temperature considerably during contact. Then in the end you'll have measured the droplet's temperature at a state different of the initial state.

So why does the experiment always end the same ? What happens when observation tools look at these atoms? Wouldnt it result in chaotic results instead of being the same result each time ? U cant tell me the observation tool is making them line up like that

[octoberride]

This isn't an explanation of the observer effect. No one understands why the collapse happens or what an observation exactly is.

[Harshverma-hvck]

Still didn't understood why only 2 stripes/ particle behaviour in observation and not something else ...your explanation didn't made any sense because you wont have any explanation for why your electron is always acting the same when light is turned on and photons are interacting with it hitting it why not something random .. just to be clear not trying to be halteful here but just a learner curious about things and I would really love you hear other opinions on this

People focus on the angle NDT gives. And its not quite right still. He's taking about the heisenberg uncertainty principle. Which is something far more fundamental than just bouncing a light off of Joe Rogan the atom (jrta). And that measurement disturbing jrta.

In the sub atomic world. Theres a trade off in how much you can know about some characteristics about a joe Rogan the particle(jp). If you know how fast jp is moving... you cannot know where jp is exactly. Jp location can be fuzzy and jp may be anywhere in that small range. And vs versa. Say you measure a cars location & velocity. With those two things you can make predictions of where that car will be in a certain amount of time. You can't do that in the sub atomic realm because you can't know both at the same time.

If you were to attempt to get the absolute best location information you could ever possibly get from jp. The amount of energy required basically creates a microscopic black hole. And as you start approaching that very specific measurement... space itself starts to distort at a very tiny microscopic way that it impacts your measurement. Because the actual dimensions of space are not what they once were. The act of measurement does disturb jp. But its not just because you bounced something off of jp. The act of measurement disrupts space AND time in the area so they don't continue to work like your intuition says they do. So the information you get back is "tainted" in one way or the other.

It would be like ther example of measuring the cars velocity and position above. It would be like if you measured the car and the moment you did the car changed size and the driver instantly changed the speed for an infinitesimal moment. You didn't measure what you thought you measured

[coatguy]

He spoke for like 30 seconds without saying anything of substance. King of yappers

[StdsRbop]

Niel is wrong and actually just dislikes the idea that we don’t know a scientific phenomena

[Pexus]

There are worms in cherries, but only if you check.
If you don't check, there is none! 😎

[Johnny-mqmo]

I just had a genius idea but I wonder if this same thing would happen if a blind man were to stand in as an observer would the particles then know they were not actually being observed? I'm positive that something to this effect has already been tried I would just like to know. I do know that cameras that were not recording were used and the affect still the same it knew when the camera was observing and when it was not so I now want to know if this would be the same with a blind person or someone simply not observing but standing near

[stacywilkerson]

The observer effect? I was thinking that it's a non factor unless you are looking at something far away like the videos of pulsars and galaxies, those vids are beautiful but not accurate because of the observer effect.

[kangtheconqueror]

They probably had to edit out like 30 mins of NDT interrupting Joe's question.
