“observing changes the result” doesn’t mean conciousness attempting to look at it changes the result, there is nothing special about conciousness (in quantum mechanics)
“observing changes the result” means we try to measure atoms and fields but unfortunately our measurement tools are also made out of atoms and fields which interact with the atoms and fields we are trying to measure, giving us a different result than if we don’t attempt to measure it
It does bring up interesting questions about what the “real” behavior of reality is tho, since anything we observe is technically different than what it would be if left alone. We can only ever know what a slightly altered state of reality is
Think of it like this:
You can use a tennis ball machine to measure how far away a house is by firing the tennis ball at a constant velocity, timing how long it takes the tennis ball to come back to you, multiplying that time by the velocity, and dividing by 2 (since you measured the distance for a round trip). This works pretty darn well for measuring the distance to houses.
But now try this same trick to measure the distance to another ball. When your measuring ball hits the ball you want to measure, it doesn’t stay resolutely planted in the ground like that nice friendly house. The energy from your measuring ball bounces the ball being measured off into the distance. Even if you could get your measuring ball to return, the ball you measured isn’t in the place you measured it.
Replace that tennis ball with a photon, and you have the basic picture. There’s no such thing as passive observation. Measuring something interacts with that thing. Conventional measurement is like in the case with the house, the thing being measured is so much bigger and more stable than the thing we’re measuring with that the effect is negligible. But once you start trying to measure something on the same scale as your measuring tool, the ensuing chaos makes it basically impossible to get useful measurements.
What happens if you try to cut a photon in half with a knife?
The edge of a knife has to be thinner than the thing it’s cutting, and we haven’t found anything thinner than a photon
Clearly you haven’t seen my penis.
By that implication it’s fundamentally impossible for anyone to see it.
Lol.
I’ve found plenty of things thinner than photons, it’s just that the photons they’re thinner than are extremely low energy.
This analogy is really well thought out. It really helps my brain understand the weirdness that goes on with measurements on the quantum scale. Thanks for taking the time to type it out.
Every road leads to Plato’s cave
My teacher had a good comparison for this: observing macroscoping reality like we do microscopic reality would be like throwing a car at another car to measure its speed or position. Obviously you alter the course of events this way.
Fortunately light doesn’t do much in the macroscopic world, so we can use it to observe stuff.
Great distinction.
What if you just measure the ambient particles
Then you are measuring something with matter still and it then affects it. Literally causing interactions to measure means altering it’s state even at a nonchalant glance.
hmm, I can get how that might cause the measured item to say, change its velocity, but not how that would cause a wave to collapse into a single point.
It’s not a physical wave. A wavefunction describes how likely something is to have different values for one of its properties. For example, an electron might have a wavefunction describing how likely it is to be in different locations. By observing if it actually is in a certain location or not, you force the electron to decide where it is concretely, “collapsing” the probability function into one value (its newly decided location).
Right but how do you measure the things around what you are trying to measure and get any data from it unless you expect them to also interact with the things you are measuring.
You have to have an interaction to measure even if you are measuring the outcome and steps away from the original interaction.
It’s like measuring dark matter where the easiest way to prove it’s existence was to wait and capture the decay of it but not the particle itself. But that means the particle was already gone when we got the measurements to prove it was there.
Measuring is a loaded misnomer. Interacting with a particle changes what the particle is doing. There is no such thing as nondestructive testing in quantum physics.
Measuring just happens to be something we do a lot which necessarily causes particle interactions.
This always bugs me. Quantum Mechanics isn’t actually that difficult. It has some nasty maths, yes, but that’s mostly slog work, rather than an impossibility. 90% of it is the Schroedinger’s equation + boundary conditions.
The main issue is that you have to abandon the particle model of reality. This is deeply engrained into our brains. If you try and understand it as “Particles + extras”, you will fail. You have to think of it as “Waves + extras”. It then, suddenly makes logical sense.
It does have some interesting implications, however, about deeper reality however. E.g. what exactly IS decoherence, from a physical point of view. Also, what is physically happening, dimensionally, when a wave is complex, or even pure imaginary. These are beyond the scope of QM however.
The big problem isn’t that the math is hard, or that’s often impossible to visualise. The problem is that a whole bunch of charlatans intentionally misinterpret what “observing” is in QM, to make money off of gullible victims.
To elaborate on this, the Schrödinger equation, which describes the dynamics of a single particle, is a wave equation and hence a lot of classical intuition from e.g. electrodynamics can be applied. It is many-body systems, i.e. systems composed of many interacting particles, which is not only mathematically complex but can also defy classical expectations due to emerging phenomena, etc.
The problem of quantum mechanic is that the physics it shows us is not intuitive, and it sometimes breaks other laws of physics.
Quantum intrication means that information travels faster than light for example. Counterfactuality also breaks causality.
It’s not the maths that are the problem, it’s that it doesn’t make physical sense in the world we currently understand. And the equations explain nothing. They merely describe a a world that doesn’t make sense.
Quantum mechanic is like having a machine from the future that does cool things, but you don’t understand how it works. It’s like people did chemistry before they understand what chemistry was. We do uber cool things with it, but it is a spotlight on our ignorance at the same time.
Actually, I think it’s time to reveal, that to some people QM is actually pretty intuitive.
It’s just that the masses and the news media don’t understand it, so they assume that nobody does. The particle worldview is deeply ingrained into many people’s brains, because it’s deeply useful to them on a day-to-day basis. If you loosen that requirement, then there’s literally nothing standing in your way to accept a wave-worldview.
What about the Copenhagen interpretation debate? What about the non-locality?
These are academic debates, not people ones. Saying that quantum mechanic is intuitive is arrogant at best. You may have a perfect understanding of the current theory and how to use it, and you maybe comfortable using it everyday, but then you should be aware of the limits shouldn’t you?
Otherwise it’s like alchemy.
Yeah ok, I get your input. The point is, that most of the arguments, that say that QM is “unintuitive”, boil down to the fact that some people are simply unwilling to accept that the world is “not made of particles”.
Some people adhere to this worldview like to a religion. You cannot argue with religion. Therefore, for most people, there is little hope to come to terms with QM. However, I am saying, that if you “give up” on a particle worldview, then QM isn’t so super weird as lots of people always make it seam.
Yeah, there’s some strange issues going on. But I’m saying, that a lot of these aren’t so mad to think about if you give up on your particle worldview. Coherence, for example, boils down to a system which isn’t simply described by “that atom goes there and this atom goes here”. It’s different, but consistent. It still reveals a consistent model with a measurable outcome. Just that this model is like taking public transport instead of riding your own car. Sometimes, you gotta mix things up to see the bigger picture.
I get what you’re saying, but I can’t help but think quantum physics is a weird beast. Somehow it is the opposite of relativity that’s purely geometric, although in 4d.
To go in your direction, I think the probabilistic nature it the biggest weird thing of quantum mechanic. And you can absolutely admit it and live with it, but for many people, that will be a tough thing to do, and they’ll rather think that our knowledge is too limited to understand the reality of things. And it’s hard to blame them for that.
IMO we lack some good sci-fi to explore and familiarise these things.
I definitely agree it’s unintuitive to the layman. We never have to deal with large scale wave interactions, on the classical physics level. I disagree, however, that we can’t understand it. It does make sense, it just doesn’t map to our default particle mindset.
I disagree that it breaks the laws of physics though. It just shows some flaws in our methodology. E.g. the speed of light isn’t a limit on fundamental speed, but of information. It just happens that the only time we can have transmission without information is via decoherence.
QM is definitely incomplete. We know the what, but not the why. That applies to most of physics however. Newtonian physics is the same. We know what happens, but not why. It’s just that Newtonian physics is intuitive to our savannah running brain, while QM requires more mental work.
So the fact that quantum physics is non-local, and thus is not compatible with general relativity, is perfectly fine for you?
QM is the only bit of physics where something can still be both physical and have zero information content. Therefore it’s the only place where the difference matters between C being a universal Vs a limit for information.
Also waves are non local, an exponential decay never actually reaches zero. Accepting this is critical to QM making sense. It’s just very alien to our natural sensibilities.
As for the conflict with GR, both theories are known to be incomplete since neither predict each other. Knowing how both differ is one of the few known holes in physics. Interestingly, both theories are ridiculously accurate, within their domains, making the job all the harder.

It has been proven that the entengle particuls are modified instantly together. Which means an information does travel faster than the speed of light.
This is the EPR paradox by the way. Which was proven true a bit less than a decade ago.
You have to think of it as “Waves + extras”. It then, suddenly makes logical sense.
Unless you observe the double slit experiment, and then suddenly it’s particles again
I mean, consciousness does alter the universe.
Here I am, altering the universe because of my consciousness.
If you mean that we make cities and culture and science with our minds, then yes.
If you mean we control reality by squeezing our butt cheeks real hard and wishing for parking spaces, then no.
Most of the time I hear this, it’s stupid people promoting the second.
I believe the more nuanced argument is that even though you think you have free will and are making choices such as “let’s build a hospital” or “I will write a song”, due to the nature of all effects needing causes, in a chain - there is no such thing as free will as there is no cause without effect.
Agreed. So far the only things we know of that don’t seem to have detectable causes are virtual particles and maybe radioactive decay, I think?
True (I guess anyway!) but consciousness still alters the physical world. What’s driving consciousness, that’s the real question IMO.
my balls
That second one… Isn’t that manifestation? Hard agree with you there, usually people promoting manifestation are simultaneously saying “you can imagine anything and make it real” and in the same breath are trying to sell you something that you evidently aren’t able to imagine into your reality for free.
On the other side, technically, even breathing is enough to satisfy the goal of “changing the universe”. That bunch of molecules would not be moving through the universe like that if it weren’t for your consciousness (but few appreciate sentience at that atomic of a mechanical level lol. I just think it’s a massive glazed over step in going from mind to city/culture/science)
A byproduct of self help hokum. Most people who have difficulties in life relating to their “success” are told to visualize their goals, and magically they’ll achieve themselves somehow. They never actually say how to summon the executive function necessary in order to perform the tasks to achieve the goals. That would result in too many middle class people.
I’ve also heard it described by the Puzzle in a Thunderstorm gang as someone being so blind and unwilling to acknowledge their privilege that they claim everything good that happens to them is literal magic. Their problems can be solved by social safety nets and coincidence, but get attributed to their “positive thinking” altering the fabric of reality to benefit them.
Fair enough. I was just thinking of more “high level” stuff that’s easier to disassociate from simple physical mechanics of cells and stuff. Trying to avoid the low hanging fruit in my examples, and all that.
Oh yeah, I just wanted to complete the picture for those who might not be able to assume all the steps, it’s by no means a fault in anything you said. I’m just adding on because I don’t mind the low hanging fruit discussions, personally. By all means, feel free to skip it, that’s what people with interests like mine are here to fill for! Don’t waste your time being stuck in boring explanations on the internet when it’s virtually guaranteed someone else will think it’s fun!
https://en.wikipedia.org/wiki/Law_of_attraction_(New_Thought)
I think this can be interpreted in different ways. One can be that we sort of go in the direction we’re looking, and there’s evidence to back that up. You don’t just magically become a nuclear scientist just like you don’t magically become an actor. It usually takes years of dedication and focus.
Another is that if we just ‘will’ it into being, then it will be so. I don’t think this is really accurate of reality.
I mean, I’m coming from a background sceptical of the law of attraction because it’s just repackaging having goals to sell self help books. How do you become a nuclear scientist? Step 1) step 2) step 3) etc.
The law of attraction is new speak used to sell known principles to people, in my opinion. Manifestation, in my opinion, is the same thing but coming at it from a crystals vibe rather than the self help vibe of the law of attraction.
I don’t mean to be a jerk about it, hence all the in my opinions, but as I said, I am very skeptical of the usage and utilization of the concept of manifestation.
All that said, you’re not wrong. The principle is valid and it does work, but it’s mustering the discipline to stick to those goals, that’s the secret that everyone is looking for. Idk I feel like I’m starting to ramble, do you have any points/counter points to any of this?
Absolutely, I totally agree with you.
I don’t really subscribe to it either. I just think it’s a fine example of something that can be interpreted multiple ways and different people will get different things from those interpretations.
:)
Sean Carroll had a great take: everything is waves in fields and we know of five fields: Strong Weak Electric Gravity Higgs
Particle behavior arises from interacting waves. So anything that acts like a particle is actually waves interfering with each other.
God doesn’t play dice, he surfs, got it.
Consciousness has nothing to do with the “observations” in quantum mechanics. The wave function collapses when we entangle ourselves with the outcome. Whether or not we actually record those “observations” is irrelevant.
The term they should have used from the get-go is “measurement” instead of “observation”. Humans will always tack on mystical mumbo jumbo if given a chance, muddying up the waters for us laymen trying to learn, and “measurement” sounds much more neutral to me.
Everybody knows you need to fall off your toilet and hit your head on the sink for instant flux capacitor.
Having to explain to your parent that yes physics requires math and that yes being a physicist is a job that requires years of dedication to fully appreciate is wild. Also, physicists are just bad at naming things, so no your brain doesn’t change reality around it because it has eye holes attached to it
“Consciousness affects outcomes” is such a cringe take, it’s more like, you’re in a 3d slice of time and where you inhabit is based on what you do and you’re allowed to do anything within that as long as it’s self-consistent, with things self-correcting if they’re not.
Continental philosophy in a nutshell. Find some cool sciencey concept, and abstract it beyond anything that is reasonable.
What would oceanic philosophy be then? Dilute everything?
Continental philosophy is so named because the Brits referred to the philosophers in continental Europe thus. The opposing school is more generally known as analytical philosophy, and posits that rigorous logic can be applied to philosophy.
Continental philosophy: “love should be a dimension, just like time, that would be awesome.”
Analytical philosophy: “I’ll buy you a beer if you can prove to me that the electron exists.”
So, continental philosophy then simply introduces more variables to tackle the problem, while analytical philosophy tries to make actual progress?
Sort of. Continental philosophy is great if you’re a stoner, a hopeless romantic, have preconceived religious notions that your philosophy must have a carve out for, or if you write for Hollywood.
Sometimes you get all four. See for example, the “totally scientifically plausible movie, Interstellar!” which posits that love permits time travel… Which this meme format would work great for ;)
a hopeless romantic
so basically french, then
I believe once we fully understand consciousness, we’ll understand the nature of reality. Of course, I could be wrong.
We’re never going to ‘understand consciousness’ because it comes to conclusions we don’t like, so it’s in our best interests to not understand it.
It always worked out in Alpha Centauri. Boom two free techs. gg
That’s an interesting idea.
Let me try. It’s all a loop. Each universe is just another conscious being’s thoughts manifesting themselves into what you see before you. In your head there is one just like what you see around you.
Very interesting. I’m in the party of both ways. Either way I see it, if I die and am simply gone forever, that’s cool. Atleast I won’t know any better, like before we were born. Alternatively, if we take reincarnation as truth, then shit, that’s extremely interesting and opens so many doors my feeble mind cannot comprehend. Really, either way I’m completely cool with. I’m just simply amazed that we are here and now, regardless.
There is a theory which states that if ever anyone understands exactly what consciousness is for and why we have one, it will instantly disappear and be replaced by something even more bizarre and inexplicable.
There is another theory which states that this has already happened.
I hope that’s not true. Just a constant horse and carrot.
Quantum mechanics makes no difference, just throw cheese at it, if it eats the cheese it’s cool and we can get along, if it doesn’t we need to shoot it.
Hey, that’s racist against asian people.
I wouldn’t call it weird, just unconventional.
Have you seen the movies? The only sane person who messed with quantum stuff is the camera man, and he never speaks of anything.
We have the many-worlds interpretation that makes perfect sense (as long as you accept that consciousness is just a function of the particles in your brain and not some spiritual essence detached from the laws of physics), but Niels Bohr had to convince everyone that Quantum Mechanics is not supposed to make any sense just so that he could win his argument against Albert Einstein, so now everyone think it’s just another interpretation on equal footing with the Copenhagen nonsense.
If only conciousness did affect reality, it would salvage the soul, which sadly doesn’t appear to exist - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8121175/
