Quantum experiment suggests there's no such thing as objective reality - Sensationalist Headlines

https://www.technologyreview.com/s/613092/a-quantum-experiment-suggests-theres-no-such-thing-as-objective-reality/amp/ Paper: https://arxiv.org/pdf/1902.05080.pdf In short, if one observer discreetly performs a measurement on a photon and collapses its quantum wave function from their perception, the photon will still be in a superposition and have wave interference for another unaware observer. This isn't possible under the laws of objective reality as the second observer's findings contradict those of the first. The paper interprets this as a potential relativity of facts, making the "truth" individual and not globally acceptable. For those unfamiliar with superpositions and the observer's affect on photons, this video has some great visuals: https://www.youtube.com/watch?v=ZQAvVgnreWk

Fuck now I can't tell someone they are objectively wrong. God damn scientists.

Gonna have to read that paper as if the wavefunction has already collapsed I fail to see how another observer can collapse it again(?). Sounds interesting

Only agent smith would say something like this

https://www.youtube.com/watch?v=DfPeprQ7oGc Here's the original video of the one in OP. The guy who made that video just took other people's content and tried to warp it to fit his tin-foil hat beliefs. I believe this video also explains it a lot better.

Beauty Truth is in the eye of the Beholder

So people can experience different realities within the same existence?

So the best theory for explaining all the observations of quantum physics, IMO, is the many-worlds interpretation. (Fight me, Copenhagen Interpretation fanboys) The key to everything is entanglement. Any time two particles interact, they become entangled - their future state is dependent on the other's past state in some way, as well as the state of every particle the other is itself entangled with. Wavefunction collapse is just entanglement with the observer - you observe a particle instead of a probability distribution, because the probability is distributed over a near-infinite number of yous, each one observing a slightly different particle. So this doesn't really come as a surprise, to anyone subscribing to MWI. Given a particle, an entangled observer will see one particle, an unentangled observer will see a particle distribution (or wave, if you prefer) - and the observers will see each other as a wave. That's no bigger a break of objective reality than relativity was.

Look no further than Trump.

Finally we know what happened with Berenstein

The comment about the video being warped for tin foil hat beliefs is pretty ironic since the whole Dr. Quantum segment is from a movie made by a cult centered around a woman who claims to be a medium who channels the spirit a 35,000 year old warrior from the lost continent of Lemuria. I am not creative enough to make that up.

I know the movie itself is pretty pseudoscience-y, but this segment isn't. Meanwhile the youtube channel in the OP is filled with pseudoscience, while trying to sell his mandela effect t-shirts.

someone help explain pls

There is the Ultra Reality and only i have seen it

everything may be subjective but my boot will still be kicking your ass in every position!

I'd just like it confirmed; It's established that the collapse of the wave function is caused by the measuring/observation device, right? Not by the information about the slit choice being observed or recorded? I feel this is such a darn rabbit hole judging by the youtube comments

I think J.L. Mackie touched on the philosophical absurdity of objectivity in his 1977 book Ethics: Inventing Right and Wrong. Even though the book mostly touches on the human side of objectivity, I see a fair bit of overlap here.

hey man if the Ramtha School of Enlightenment did anything it brought a lot of money to the town nearby me and got us a cool movie theater

I'm not smart enough to engage with the arguments that led to this intepretation, but I am skeptical. Infact, it may be precisely because I am ignorant that I am skeptical. I don't know much, but I do know that we are really good at getting ourselves into paradoxes and drawing wild conclusions from them. I am not convinced that there isn't an objective reality any more than I am convinced there are no other 'real' people in the world. If one is true then so is the other.

A surprising amount of the science in Dr. Quantum is alright, but with regards to interpretation it has a pretty clear agenda, but they're definitely presenting the "observer" idea with an agenda (your mind creates reality etc.) Modern ideas about the measurement problem are very different from what they believed back around the time quantum mechanics was being created, and people like Wigner who believe conscious observation is somehow special in the measurement process are pretty far out of the mainstream these days.

Whenever a quantum fuckery happens and truth becomes simultaneously false we feel a deja-vu or jamais-vu because our brains arent ready to cope with it. Fight me

ramsters are absolutely weirdos, not defending them or anything more making a joke. i've always wanted to try sneaking onto their compound but that's a risky as fuck proposition with the security they have. there are some strange buildings on their property, like what the hell is this supposed to be? https://files.facepunch.com/forum/upload/130/2c81a554-dad7-4490-ba70-ec611e44e4fa/image.png

So.....i can go back to believing that Toto actually misses the rains down in Africa?

I don't necessarily believe that there is absolutely no objective reality as much as it is considerably more flexible and complicated than it may be initially assumed.

So the core thing to remember is that everything adds up to normal. Quantum theories can have all kinds of weirdness happen at small scales, but if it doesn't add up to normal at human scales, the theory (or your understanding of it) is wrong. As I understand MWI and this experiment, there is an objective reality, or at least an objective past. Different particles have different levels of knowledge of that past, but particles cannot have contradictory pasts. If Particle B saw A as a particle, and Particle C saw A as a wave, Particle A will be somewhere within Wave A. And since we're made of particles, we also have a single past that we have observed to some level of knowledge - either "things happened somewhere in the ballpark of this", or "this is exactly what happened", depending on whether our observation saw particles or waves, but at a macro level everything gets entangled and so everything acts like particles, except sometimes light. So for all practical use, there's an objective past. Things only get weird if you try to consider multiple worlds' "present"s at once. And even then, you just get multiple objective past realities instead of one.

does this mean the "are traps gay" argument will never be resolved

STIRNER WAS RIGHT GET SPOOKD NERDS

Maybe it's just a bombtastic airsoft arena? You won't know until you join.

The articles explanation of it is honestly pretty poor, what exactly did they do to prove this? I'm not really sure how you can take two simultaneous measurements like that, the equipment itself would be considered the observer and collapse the wavefunction.

There's an arxiv link at the bottom of the article
