What has confused me about the idea of quantum foam is that it would have to be Lorentz invariant, right? An observer travelling at near c relative to the comoving frame would not be able to tell the nearby foam has changed in any way. That seems intuitively wrong, but who knows, because relativity isn't very intuitive for me to begin with. Oddly enough I am in the market for a wallet.. going to check it out.

Yes, the Lorentz invariance is the issue. Well, for one the foam could just break it. It's not like that's illegal, it's just that it's theoretically difficult to make work without screwing up other things. Then some people have argued you can just "deform it". Which I think is nonsense, but I've given up fighting this fight.

@@SabineHossenfelder The idea that quantum foam would conflict with Lorentz invariance, surprises me. Surely one can put a measure on spacetime which is invariant under Lorentz transformations, and then one could model a stochastic process in which points are selected randomly within spacetime, with uniform density (with respect to that measure), and that process would be Lorentz invariant, I believe. (Not that the individual samples would be, just the distribution as a whole.) Then, with superpositions over the different ways the fluctuations could be, I would expect that this superposition would kind of “average things out” in a way that, analogous to the stochastic process, keeps the Lorentz invariance? I’m surprised that a deformation of the group of Lorentz transformations (or, really, of the corresponding Lie algebra) would be something that would be needed to appeal to for this. Like, to be honest, while stuff about deforming SO^+(3,1) , or (as another idea that I think is probably related, but not 100% sure) spacetime having slightly non-commutative geometry, seem like very interesting ideas, it seems hard for me to find them likely to be true?

Great video. I have been supporting a greater role for quantum foam for the last 9 years. Of course the standard model doesn’t support these “crazy” ideas. However I see support for this in some models and unified field models. For example, Dr Finster and his group have made a lot of progress and has many new ideas.

The quantum foam reminds me of Richard Feynman's eponymous diagrams. They describe interactions between two particles as the weighted sum of each of the infinitely many ways that they could possibly interact using "virtual particles" which may or may not exist but are fundamentally undetectable directly. Likewise, the quantum foam may or may not actually exist but I think we need the mathematics of it to refine our understanding of the fabric of space and how things move through it. On a related note... if the quantum foam is experimentally verified, does this give new life to the "tired light" hypothesis (or some version thereof) to explain the redshift of distant objects?

Amazing experiment great lesson......

Hi Sabine, I'm the one who conducted this analysis and wrote this paper at IceCube, and I'm not sure what you mean in terms of this analysis being a calibration step towards the "real thing". This analysis was solely dedicated to searching for decoherence effects on neutrinos with no implications for detector calibration whatsoever. Moreover, our results are now the leading neutrino decoherence measurements by several orders of magnitude, so I would say that we actually accomplished the "real thing" versus this being a test.

I thought GRB's were the one strong signal we can calculate when it originated, because of the neutrino-emission arriving hours beforehand?

I’m more excited about the follow-up experiment to find the quantum beer.

If an electron (modeled as a classical point like charged particle with a rest mass and not a wave) "fell" into thru and out the other side of a nucleus, then (because it's so light) it would be accelerated to very high (relativistic) speeds. This would cause an additional attractive force between the particles while they are close by (but they would be close by less often due to relativistic inertia). I strongly suspect that this is why electron orbitals are shaped the way that they are. Furthermore, with this new perspective of dynamic inter atomic mass in mind, it makes sense to consider that the same effect might be happening within the nucleons themselves. Instead of quarks being mediated by the strong force, it seems possible to me that Protons and Neutrons are both stable 3 body systems of 1 electron and 2 positions each, where the Neutrons only appear neutral to outside observation due to a statistical effect where the electron is moving the fastest and is the most energetic, effectively "shielding" the inner 2 Positrons. The Positrons being able to work together to pull the captured electron inward instead of pulling it between them like in the Protons would lead to it having more KE on average and thus a higher relativistic mass on average, explaining the Neutrons higher mass. Hopefully, such a perspective would allow a combination of gravity and the electroweak force to explain the strong interactions, as Neutrons would have a outermost electron, and Protons would have an outermost position, making them attractive to one another. Obesrvations of heavier generations of Fermions could be due to post collision transitory nucleon compression storing energy elasticly (and thus slowing down) leading to erroneously attributing the missing energy to higher rest mass particles to avoid violating conservation of energy.

The shapes of the electron orbitals are already adequately explained. Use spherical harmonics to solve for the wavefunction for a particular spherically symmetric potential well. I don’t think the thing you propose would produce these orbital shapes. Also, the thing you said about quarks, Well, while I’m not exactly familiar with how they do the experiments, suffice it to say, there’s a lot of experimental evidence that your idea is not taking into account. There was the whole particle zoo, and the eightfold way, leading eventually to the quark model.

Thank you for your wonderful explanations. And the jokes are very good too 😜

The one thing that has bothered me about the notion of quantum foam is the idea, in my non-scientific understanding, that particle pairs come into existence by borrowing energy from the vacuum. That just doesn't compute for me. On the other hand, if the foam is pervasive throughout space, what differentiates it from the previously debunked aether?

Fascinating. 🖖👽🤨

Sabina still waiting for her superdeterminism machine. Me too, I hope you get it. So lets talk about scale, quantum fluctuations of the foam. So lets first describe the system, neutrinos that go through the earth. The Earth is 12,000,000 meters in diameter, lets just say 1E7. A planck unit is around 1E-35 meters. So the scale of the experiment is 1E42 planck units. Now if nutrinos are going to undergo decoherance traveling through the Earth at something like 1E40 planck time units of 1E42 planck distance unit. One not only expects one event per neutrino, but millions. They should be randomizing, and if they are not randomizing then we probably should conclude thar planck level quantum gravity behavior so fine scale that its not able to affect the coherant state of a particle but only incredibly rarely if at all. I like the quantum foam hypothesis, but it has its limitations, but the key point here is how to fixit so that it works. The LQG people have been working on this for decades. Maybe what they need is a little superdeterminism to get them going.😎

Quantum Foam: I just like the idea that at the sub-nano (atto?) level there might be complete new layer of physics we have yet absolutely not idea of and just see some of the ripple effects of..

Probably, we should have more interest in neutrinos. It has many interesting properties that we could use to experiment things.

I’m no physicist but my intuition tells me that gravity is an emergent effect, not a fundamental one. So it may not exist at all at the quantum level, it’s gonna be just as hopeless and the search for dark matter. This is my opinion and it’s completely out of left field, but gravity must be correlated with entanglement. It’s like when enough particles are entangled with one another the universe would rather just lump them together, and that correlation between them manifests into a “real” force that’s physically drawing them together at larger scales. It seems like gravity is the result of some sort of conservation law.

I dont know how to compare particles with space-dimensions, thats what gravity is about, curvature of space. But, as long as gravity cannot be shielded, it must affect all dimensions, if there are more than 3. So looking for "gravitons" will never be successful, but maybe you find more dimensions. The ones above 3 would be very tiny and enrolled into the 1steins 3 dimensions, this should be the things to look for in the first place.

0:45 it wouldn’t be so crazy because the differences share with each other. which is why the quantum fluctuations are relative but still potential because the patterns are there but the differences could be far from each other like how galaxy’s don’t form the same in different areas because of the differences. The quantum entangles and the entangled parts reveal a whole like a human or a dog or a rock and then the differences aren’t shared in only one way but the differences can connect and reveal how they connect because they don’t need to know themselves. We are part of the universe but we don’t believe we are the center or all there is even if we can’t see because the future is blurry with differences. The collapse is basically growth but also deconstruction and sharing. Father, son, Holy Spirit thing. Not one but sharing even beyond the triangle and able to expand or devolve and share the differences. That’s why we loop and share so we don’t follow one direction and take or give our pieces away to the ones that take. Same thing religions try to talk about but people just don’t understand or understand it in differences. Like angels and demons but really those are just words that have infinite connections but the differences share like patterns overlayed. Honestly quite scary but not because of an end. The scary part is living and all this that’s being forced upon us by each other and what is to come. It’s looking like we may build a hell first and then grow from our misunderstandings. The real and unreal are not so far from each other and to force us to pay with our lives for portions of reality is disgusting. I understand today’s people and the minds but it’s all manipulation. We are forced into relying and then told we can’t farm or gather and share, we can’t even think without being torn apart by our current reality. Maybe we need this to learn how to share.

@5:00 why are they looking from the north to the south? wouldn't it be easier to do the same from the south to the north? surely there is no polarity to the way these particles are traveling? Just a a thought

Are we looking for quantum gravity near the surface of celestial bodies? It spears according to the concept quantum foam should exist at the edges of celestial bodies?

In 2:44 she says that the effect would be more noticeable on higher energy wavelengths but the graphic shows red light, with the lowest energy move the slowest. Does that mean that it would speed up light or is this a mistake?

Is it possible that "dark energy" is not actually a source of energy behind the redshift, but instead is a diffusion of some sort? If an unknown quirk to gravity (edit: gave it a few more minutes of thought- or light) is that as it ages/large masses spread further apart, it gets weaker, then we would get a red shift if that loss of energy is more than the current force holding the objects together (or our relative measurements of light) This might seem counter to another issue of so much "dark matter" being in the universe. But if that dark matter is actually just an incalculable amount of primordial black holes, could the structure of galaxies also being influenced by the locations of the relative concentration of mass, not just their existence? Maybe the CMB in some way provides a "drag" of sorts on particles/protons but we haven't noticed yet because relativity would keep any changes relative and we have no way to measure that yet?

I was thinkg about this... The problem with gravity is its too weak - so looking for it to marry with quantum theory is impossible as it would be statistically impossible to measure it or see significant deviation from expected values. So perhaps the way is to work backwards from a large object - like a planet - and factor in a value for mass ... then factor in to Avogadros number for atoms in a molar volume to get an atomic gravity factor. If nothing else it'll give the level of variation for the force....

Quantum and relativity gravity may be connected through the light speed. If gravity has any relative parameter related to light speed or electromagnetic field they are already connected, just need to find this relationship.

1:19 if the quantum is nonsense then what is all the evidence and research? It may not sound the way we like or align with what we think but it’s still there. The foam isn’t really a foam but a descriptive word to help people understand. Yes it’s similar to a literal foam but it’s not just bubbling, it’s sharing so the bubbles are relative like environments and such and how we can see the sharing through the patterns and chemical structures. It’s not like things that are not present don’t exist.

Albert said „Der Alte würfelt nicht“ (God does not play dies). But I guess, he might agree with „Der Alte legte eine Patience” (God puts patience). All cards are on the table. Some of which you can see or have already seen, and others are (if you - as nature always does - follow the roles, simply not or not yet observable to you. You have no chance other than remember as much as you can and calculate probabilities. What now is the difference between playing dies and putting patience? The cards can considered to be „real“, no matter face up or face down. But Alberts dice can’t as long as it is rolling. Besides: If you cut one card into two, both pieces are really entangled. You only need to turn one part face up, to immediately know, what the face of the other part is, wherever it may be. 😢Of course, as always, there remains one small but possibly essential problem: With respect to the measurement-operator, In quantum theory there is only a spectrum of all the possible states observable. Opposed to this, all cards in the stack can be turned face up sooner or later. But don’t let us be too petty: Alberts rolling dice never is in a superposition of the six numbers written on the faces of the dice. It is just unobservably rolling in or outside the cup. I guess, in quantum physics it’s all about resonance. If you doe a measurement with respect to the universe, you get a wave (which you at consider as retarded field); if you measure it with respect to a certain domain, you get something like p a spectrum of a Fourier analysis; if you measure it with respect to a single point, you get an particle. Anyhow, the result of any measurement is a well defined perspective only.

So we have to assume that these particles travel with no state change from fare away but they change when they hit this foam on the north pole? Did I miss something?

“Quantum foam makes me roam” -Michael Crichton

I would have thought that if there is any spacetime foam at all it would be on the scale of Planck length, i.e., 1.6×10^(-35) m. So, even for quantum phenomena spacetime should appear perfectly smooth. The question may arise if in the Planck regime "quantum physics" is even applicable. The Planck regime is more distanced from quantum physics than quantum physics is distanced from classical physics.

I think if wavelengths are involved at all, they'll observe an ultraviolet catastrophe. But I seriously doubt they'll observe a "foam", but rather, moving beams and random intensities that look more like static than foam ... IF they detect anything quantum at all. My bet is that space is NOT a wavy fabric, but is full of nothing and that any fluctuations are coming from the interactions of large objects (strong peaks) or else every object in the universe (static).

So why would this new ICECUBE experiment be particularly sensitive to quantum foam fluctuations interacting with neutrinos? Even the shortest wavelength gamma rays detected are still 14 orders of magnitude larger than the Planck length. Maybe a graph of the power spectrum (or maybe probability) as a function of length / size of the “theoretical quantum foam fluctuations” and how that would “govern the interaction rate” of photons (or neutrinos) of different wavelengths would have been interesting. Considering that the neutrinos probably have a much higher probability of interacting with the “energy ⇔ mass” contained within the earth than the “quantum foam” fluctuations how are the researchers separating out the two types of interactions with reasonable sensitivity‽ Also why would Albert be “bothered” by quantum foam? Don’t be a tease, his thoughts would be very interesting. Also what is the difference between “quantum foam fluctuations” and “vacuum fluctuations” as it seems that both have something to do with virtual particles? Considering the “slight” discrepancy on the energy content of the vacuum energy from theory, how does that relate to this?

What happens to both create and dissipate the energy difference between the 3 types of neutrinos?

2:50 should be the other way right ?

While it's true QM contains all possiblity, but calling the 'fluctuations' is messleading. They are not changes with time, but the superposition of possible states.

Could this theoretically apply to gravitons for quantum gravity fluctuations?

We live in a universe composed of non quantum gravity, space and time with quantized mass and energy embedded in it. Gravity, space and time exist separate from mass and energy and the two cannot be unified.

maybe this is a bit dunce but wouldn't a foamy space give it that ability to compress and expand to fit with spacetime curvature? to me (analogy wise) seems to work very nicely with general relativity.

I agree that the correct procedure is to make a theory and then test for the desired outcome. But I have an inkling too many of these theories are bogus (meaning the researchers already know the theory does not work) and just a money gathering exercise to keep these physicists fully funded.

Layman here. I don't know where I got the idea, but I don't fully believe we are objects moving through space. I have this idea that movement is just a series of snapshots of different energy states generated by the fundamental fabric of the universe. Like when you take a sheet and make waves with it. All the stitching stays bound together, but you see the wave travel. Are we just waves in an otherwise static, multidimensional sheet? Are atoms and the vacuum of space really separate or just different representations of something supremely fundamental?

@Warp9pnt9 I'll check it out, thank you!

When light passes near the event horizon does the thicker/denser space squash/slow the waves the same amount ? If so then a foam might be the cause -

It's been my understanding that neutrinos are inert. If we run a neutrino through the quantum foam and nothing changes, is it because the nature of the neutrino or because the foam isn't 'real'?

My sense is that gravity is not quantum and is not a force, but is the effect of constant acceleration of all matter into the dimension(s) we call time. I am not a physicist, and have never even taken a physics course. It is just my sense.

I don't get quantum fluctuations. For example a harmonic oscillator is in it is not fluctuating but rather is in a superposition of positions and momenta. The superposition is not changing.

If you think about it, it doesn't make sense for quantum effects to even exist unless the spacetime itself plays a role in them. So the spacetime is equaly weird as the quantum particles, we just don't know how to measure it to show its oddities.

Energy doesn't get destroyed, it just gets transferred or pored into other areas.

Keeping banknotes in books that you wrote and are sure nobody will ever read is a long standing tradition
