'There's NO Wave Function of the Universe!': Carlo Rovelli

[ryanjbuchanan]

It's interesting in that he talks about describing the "totality of the thing." In this way, integration or floating points are a little bit voodoo as well, and I would say transcendental numbers. We sort of "reduce these things" to the truncated version, but this arguably gives us as much effective information as the complete picture in the world that we work in.

The full episode should be interesting!

[DanFrederiksen]

That didn't seem like a meaningful argument. Just because we can speak of a solid object as having a simple wave function and multiple free objects would need a more complicated description, it does not undermine the wave nature on a large scale. So that sounds like he's hunching there is something more somewhere and he tries to inject that at the multibody level without any particular reason. One body quantum tunneling through another would seem like the wave nature applies broadly. Unless he means it's not obvious that the root foundation of the universe is a wave function in which case I'd say that's slightly premature to get caught up in that. We haven't acknowledged UFOs or even ball lightning nor do we know what cosmic jets or the galaxy spin anomalies are so it's a bit premature to answer the ultimate question.

If a person holds up a pen and another 7 People observe it, is one pen with 8 wave functions.

Just want to make sure I'm understanding correctly, by summarizing in my own words: the wave function concept was developed to describe the interaction between only a measurement device and a finite sized system being measured. Extending the wave function concept outside of that limited sized interaction does not necessarily follow and could be considered a "leap of faith". Is that more or less it?

Many thanks!
Carlo Rovelli in "Physics Needs Philosophy / Philosophy Needs Physics" (2017) presented outlined a list of issues and topics currently being discussed in theoretical physics. It can be seen that most of the questions relate to the sphere of philosophical ontology. And this list is not complete. The first question on the list is "What is space?" Second: “What is time?”.
Interestingly, Carlo Rovelli gives today an answer to the question “What is space?”
How many dimensions does Rovelli’s space have? What is its ontological structure?

Pavel Florensky: “We repeat: worldunderstanding is spaceunderstanding.”

1. In his paper he commented quantum state/wave function is not a realistic interpretation of the universe.
2. It is representative of something else in the background.

Thank 🙏🏼 you.

Then, he need to argue about a diferen't fundamental theory of físics than quamtum mechanics, because the Wave function is fundamentally attached for the systems described by quamtum mecánics. It represent's the probability distribution of a System to be in a partícular stay (including states of superposition and so one)

I get what he's saying with his pencil example but it's still a pretty flawed explanation. The sun would have been a better example since it is 'crafted' by the universe and not a human-manufactured pencil. It's true tho that we can't fully grasp the quantum world but we are trying/have to put it to practical use with quantum computing. But to think of the universe, maybe like the Planck mass, as a giant wave function is an interesting idea. Gravity and quantum mechanics were really the big players during the early universe. Maybe like a quantum entanglement-induced collapse in the early universe but a 'universal wave function' collapse. It's honestly an interesting idea.

3:36 I hate shorts, but the last part could be made into one. - I don’t think that what he said before helped much in understanding it though…

[Gan_Gineandro]

Just starting but I need you to interview another Italian as well about this stuff.
In fact, you might even want to interview me. It's a long story.

[KaiseruSoze]

I.e., The universe can just do it's thing and doesn't need a human to form statements that represent what it is and what it does.

[Aquaticphilosophia]

Most of the universe is consciousness so it is listening, not the noise.

[haqk]

I'd like to see him explain the double split experiment.

I had a strange incedent yesterday when i took 2.2g of mushrooms.

I'm fairly well versed in psychedelics and understand how they work. However this was the first time doing mushrooms specifically.

One thing I realised, was when I looked at my phone - my brain just wouldn't process it. I saw the colours, I understood the concept of the phone perfectly, but my brain just basically said - "no can do. Sorry." It was like I'd reached a fractal limit within reality, I was fairly cognizant, and I was enjoying my experience objectively, so I knew I wasn't just 'high as balls'.

There was a genuine discrepancy between technology, what was going on inside my phone, and the rest of my trip. The visuals were completely different, but only inside the screen, the outside buttons were fine, the shape too didn't move much, I knew what a phone was conceptually, I even remembered how to use it, but looking at it - it was just jumbled up information, and I couldn't even grasp a small part of it to extrapolate how to work the rest. It was just - gone. Now, if I was 'tripping' per se, I'd expect the experience with my phone to be fairly cohesive, as in, I wouldn't understand what the 'device' would be for or, I wouldn't know hot to unlock it with the button on the side, but that was still fine.

It got to the point where, even as I started to become vastly more lucid, my ability to process the information coming from my phone screen was still compromised. Which was puzzling, the fractals had stopped, the hallucinations had pretty much vanished - yet for some reason, this specific part of my experience hadn't caught up with the rest of it. Now pretty much sober - I just completely gave up trying to check my phone, and said "Sod it, my brain can't handle this yet. I'll sort it later."

[mattsapero]

I disagree. The entire universe is literally one wave function, the quantum foam, the zero point energy, the chi/ki energy. All is one. Don’t pray to a deity. Meditate and use creative visualization. It works. Dude is clueless. That’s my read.

[bigtrouble]

the funny thing is... he is using words i am familiar with but he is speaking WAY OVER MY INTELLECTUAL KNOWLEDGE.... for example... if the scale of knowledge was from 0 to 100.... conservatively this guy might be at 80.... right? ok well... most of the folks he is used to speaking with hover around 60... and of course some are around 70 and even a small number of folks may be around 85.... but the vast majority of human beings are at around 10 to 20 on this so he thinks he is explaining himself and his ideas in a way that most folks will understand but in reality 10% of most humans will even sort of grasp what he is trying to explain.... the vast majority of folks arent concerned with all this higher learning nonsense because they cant even fathom how it affects them on a daily basis... his explainations... although brilliant and game changing will fall on literaly DEAF EARS to these matters because they simply cannot connect the scientists need to do A better JOB AT DUMBING IT ALL DOWN SO THE AVERAGE JOE WILL UNDERSTAND JUST HOW IMPORTANT THIS all thank you for reading my rant.... peace

[erawanpencil]

The totality of everything COULD have a wave function if one describes it as a noncommutative cohomology. See palatial twistor theory; there's a video of Carlo asking Roger questions about it somewhere...

[siirmartin]

Does that mean that two observers can observe two different wavefunctions for the same system? And I mean calculate different values for the wavefunction. I know that you can never really observe the wavefunction.

Chaldean mind wants to claim simple unified determinism at the top of higherachy lie to itself as it pushes complexity into many different disciplines, within each is 2 competing archyrpical minds, each industry is forced to absorb all the statistical corrections that causes them to rationalize the system completely different to others using the same matter, similar equations.

In a classroom or mathematicians no longer aid the practical work in the feild its disconnected and living in platos cave but in 1900s it was allowed to dictate this down upon all.
The unification should be between individuals and workers where the equation fails and everything beneficial to all matters!


Remember physics is supposed to be after the fact scribble recordings of man made dashboard filtered systems like skipping a rock over water then preserving and teaching it to others. The unification is here where it matters..
Its supposed to complex in the classroom . Theyre supposed to unify working advancement on earth
