Each dimension has its own laws. Energy is quantized by its ability to break the laws of a given dimension. So breaking the laws of the second dimension takes place when the energy amount within a particular field of space grows too much to be constrained to a lower dimension. The way to bridge the physics is to look at it from the lens of what the current laws are. Classic Quantum to me is the second dimension and the first dimension mixed together which is the mistake; separate those two things so they can be cross analyzed and the math can then predict general relativity when it is correct.

@@AdrianBoyko Are neutrinos or photons even 2 dimensional energy? It seems to me like energy space and time exist in the first, second and third dimensions. With only one direction to travel in the first dimension, energy cant interact with itself. But it can vibrate in a perpendicular direction, which could be the foundation for the second dimension. Now with two directions to travel, energy is like a sheet of paper, vibrating up and down and outward from the source. In all directions. Hence, interactions between energy mixed with this natural vibration field in the second dimension are the foundation for the third dimension. Energy continues traveling in one direction, and two, and then all directions before approaching the speed of light and then breaking it, curving out of existence - potentially into a new one as the equation flips back and forth between 0 and 1 and 1 and 0. It's just a battle between energy's infinite expanse and space's infinite vacuum.

I had a similar idea. Without using a fundamental particle with no charge, ie neutrinos [which, good luck...] I don't know how you would avoid entanglement via the EM force, especially since it is orders of magnitude stronger than gravity. With macromolecular structures like nanodiamonds its even worse, since the close the streams get the more orbital overlap can happen (kinda like Van der Waals interactions) which I think makes the problem worse, so maybe neutron beams would be the way to go...but then you have to worry about the quarks zipping around in the nucleon causing short lived distribution imbalances that could cause coupling.. One thought I had, no idea if this would really work though, is that maybe you could calculate how you would expect the correlations to change if the entanglement correlations were purely via entanglement through the other fundamental forces. Then, if you build up enough data, you can see if you are observing more entanglement than you would expect (0.700000000 vs 0.700000001 type of thing) and, with enough measurements, be able to claim "There is a 5+ sigma result that we observe more entanglement than expected when accounting for all other known fundamental forces capable of entaglement. Therefore, gravity must be providing an additional avenue for entanglement and must be quantum. You can make out my Nobel Prize to Dr. P. Sherman, 42 Wallaby Way, Sidney, Australia..."
@armagetronfasttrack98083 ай бұрын
Haven't looked into this topic in detail, but the nanodiamonds are charge-neutral so don't have direct charge-charge interaction, and the dipole-dipole interaction potential decays as 1/R^3 whereas the gravitational potential decays as 1/R^1. So possibly, if the nanodiamonds are far enough away (while still being close enough to see some gravitational effect), the gravitational interaction might dominate over any EM interaction.

@@danij5055 I know, but they are talking about how a fundamental force can induce an entanglement effect on two particles, which you then can observe via correlations in the particles quantum properties, in this case, correlations in the spin of the two particle streams. You still have to contend with the fact that electromagnetic interactions can ALSO induce entanglement between particles, as it is also a quantum mechanical force. The concern is that, because EM is orders of magnitude stronger, the effects of gravity can be washed out so that you only see how EM is influencing the correlations in spin and, by proxy, the entanglement of the particles in the neighboring streams.

Yesterday I've aquired strong evidence of *macroscopic objects being in superposition.* I was maintaining my bicycle and after disassembling rear wheel bearings I've extracted 9 bearing balls from one side and 8 balls from the other. What's the heck, I thought, it should be equal, so I searched everywhere around to find that shiny metal ball of almost size of a pea - and it was nowhere. Well, I carefully inspected the casings, and couldn't really tell if they are equal in diameter or slightly different, as they have a bit unsimilar design, and I hadn't got any appropriate measuring tools to get casings' inside. Well, I thought, maybe they are inequal, as one I've extracted less ball from is indeed located it more tight spot, thus it theoretically could be narrower. Long story short, I wasn't sure if it should be 9-9 or 9-8 balls, and had no way to properly _measure_ needed quantity, so the missing-or-not ball stayed in this superposition until I performed all required maintenance, applied new grease to the bearing and started filling casing with balls. And after I've put 8 balls in there were surely a gap for the 9th one, and *immediately wavefunction have collapsed* and I saw the freaking 9th ball right in front of me, completely exposed and not covered by anything happily laying and freaking shining at lights! The only way I can explain why I haven't seen it before is superposition. No other way, really 😂😂😂

Could a quantum gravity test be designed that's analogous to the photoelectric effect experiment, which showed that light is quantized? Low frequency light had no cumulative effect on a metal target, but if the frequency was high enough, a single photon's quantum of energy was large enough to kick an electron out of the metal. In the analogous experiment for gravity, a stream of small masses passing near a test object might or might not have a _cumulative_ gravitational effect on the object.

@brothermine22923 ай бұрын
>LaserFur : I like that idea, because neutrinos wouldn't interact with the crystal via the electromagnetic force or the strong nuclear force and would only rarely interact via the weak nuclear force, and we know how to make a stream of neutrinos (as in the DUNE experiment at FermiLab). But neutrinos weigh so little that it might be difficult to distinguish their tiny gravitational pull from thermal noise or Heisenberg uncertainty. Instead of passing the stream through a cooled crystal, another possibility is to pass it near a small mass floating in zero gravity, looking for a statistically significant change of its location. Because gravity is such a weak "force" it might make sense to start with a stream of particles or atoms or molecules much more massive than neutrinos. The device presumably wouldn't need to be as sensitive.

>DebateTactics : No, the experiment that Planck reproduced, and famously theorized about, was about black body radiation, not the photoelectric effect. Planck's analysis of why there was no "ultraviolet catastrophe" (predicted by classical physics) suggested the _emission_ of light is quantized. That did NOT demonstrate the photoelectric effect, in which the _absorption_ of light was shown to be quantized. The photoelectric effect was discovered by Hertz and analyzed by Einstein (for his Nobel prize), and Planck rejected Einstein's conclusion until Einstein convinced him in 1911. Black body radiation is in no sense analogous to the experiment sketched in my comment. Although I appreciate your reference to the paper about a proposed experiment to detect single gravitons (produced by massive astronomical events such as neutron star mergers) by stimulating emission in a large resonant mass, that's NOT the aspect of the photoelectric effect that my comment is about. My comment is about trying to detect a _cumulative_ gravitational effect in a situation where the gravitons, if they exist, should have too little energy to have a cumulative effect... analogous to the low frequency photons that had no cumulative effect in the photoelectric effect experiment, contrary to classical EM theory. Detection of this cumulative gravitational effect would indicate gravity is classical, not quantized. If you reread the last sentence of my initial comment, you'll see my comment is about trying to detect a cumulative effect of weak gravity, not about trying to detect gravitons.

Another weird thought that comes to mind, and I know I've had some outlandish thoughts here, what if we're misinterpreting quantum entanglement and it's actually dimensional entanglement. This could explain why they can show such a instantaneous reaction mathematically. That also makes me think with my last comments, what if we're misinterpreting the true state of the fabric of space and it really needs to be looked at dimensionally. To reiterate with the end of my last comment if space is a fabric it has to have a certain tautness. That tension has to be the same throughout the whole universe for masses to show different gravitational forces on an equal and measurable scale. This means that I don't think we'll ever truly understand gravity until we understand what that underlying fabric and the forces acting on it really consist of.

@@isitme1234 I didn't add any dimensions and can you describe what a dimension is because the way we describe dimensions right now is through perception. A two-dimensional object is drawn on a piece of paper you cannot see on the third dimension which is the sides. We are a technically three-dimensional object because we can move any direction within the three axes. I am at no point arguing that there's another dimension. String theory also works in the third dimension. All it is saying is that everything is made up of a series of strings and if you look at the waveform of the particle you can almost see the string structures protruding from the center out toward the edges making a ring structure. This is because the particles are vibrating at such a speed that they look connected and look like strings. Is constant vibration can be thought of as a piece of yarn joining with another piece of yarn and when they oscillate fast enough they will become one. Essentially they will tangle themselves up and not at the point where they lock. This is how mater binds to matter. It's the same reason why tendons tend to knot at the end. Do fibers have become frayed. Fractal geometry shows that if we zoom in on something the design stays the same but miniatures. If we are saying string tendons on a macro scale imagine what we will see on a microscale watching them bind to each other. It's the same thing throughout the universe. Everything is made up of small vibrating particles that we perceive as strings due to the fact that they are moving so fast we cannot comprehend the individual particles. That's what string theory is, it has nothing to do with another dimension. Hopefully this opened your eyes and explained things a little bit better. I still don't believe in a technical fourth dimension unless we're looking at it on an electrical side. If I'm going to look at things in dimensional structures I'm going to look at them as their ability to interact with things that we can't quite interact with. Something like a neutrino would be operating on the 4th dimension in my opinion because it's moving so fast and with such little mess that it can pass through almost anything. I do not think any kind of dimensional being has ever been here nor do I think we will be able to cross into some other dimension. If we do ever make some kind of Transit it will probably be from physical to digital. At that point I would argue it once the body is gone you have died and what is left is an echo in a machine. You are completing string theory with dimensional theory.

Here's a question: if a clock where placed equal distance between two equal masses, how fast would it run? Einstein's gravity tells us that the closer a clock is to a mass, the slower it will run. For the above clock, the two forces of gravity cancel each other out. So, will the clock run at a speed as tho there were no nearby masses? Or would it run twice as slow as when it is that close to just one mass? Or will it run at some different speed? If it runs at a speed that is not the same as if the two masses weren't there, then gravity is not a field and neither the classical or quantum descriptions would apply.

@aggies113 ай бұрын
Any of the theories could be true, but I do have a fondness for yours, or any of the slight variations. Could be gravity AFTER the wave function collapse. It could be collapse *because* of gravity (not gravitational interactions) but rather once the quantum system's effects grow large enough to start to impact General Relativity, the wave function collapses right at the border of gravity to "preserve the nature of reality" (Ie. "QM happens in between the margins of GR"). Or maybe it could be that Quantum effects of mass lead to small scale classical effects on gravity eg. a quantum superposition could lead to extremely small oscillations of gravitational waves that represent all the potential states, that are either too small to make any differences or changes in GR. Or that the oscillations average out statistically to a net neutral effect. All of these are fascinating to consider. But any theories will require experiments with gravity, which with such small forces at play should necessitate extremely tiny scales. So I don't think the work needs to be done in theory, but rather a breakthrough by experimentalists who can come up with a brilliant insight on how to test these feasibly.
@spencerwenzel73813 ай бұрын
This is an interesting idea! It makes me think, does the particle have mass before the collapse? I think this because it is mass that creates the gravity. The shape of the wavefunction is dependent on mass but perhaps the mass doesn't curve spacetime until after the collapse? This would be convient as it would preserve locality.

@@spencerwenzel7381 Yeah, conceptually it really gets down to the core "mystery" of QM. If "reality" at it's lowest level only exists in discreet non-continuous "quanta", does that mean that "nothing" exists in the spaces between those quanta? Instead of the old "how can a particle be in two places at once", could the answer actually be the inverse, that a particle is in"neither" and for all intents and purposes, does NOT exist, until the collapse. Or to put it more nuanced, does not participate in our "classical" physical reality, until it collapses. Fascinating stuff to ponder. But this is science after all, and ideas are cheap, we need experimental evidence to really give us something.

The issue is more so about discovering the cause for gravity, and if we can quantize it then that means a graviton exists (a gravity carrying particle). Scientists want it quantised as it becomes very easy to work with if a graviton exists, and that would instantly be used to explain dark matter, dark energy, expansion of universe and more. It's a simple answer to numerous unsolvable problems. If it's something else, then these problems remain unsolvable.

We use wavefunctions to predict behaviour of particles not because the particle randomly choses states, but because we lack the information required to show the particles progression. This is because whenever we take a quantum measurement, it is destructive in nature. You're firing photons, using magnetic fields to warp movement etc. It forces the particle to change state. Also quantum particles change states because there's so many things interacting with it that you cannot truely isolate a particle. If you could, maybe the particle would maintain the same spin state infinitely, we will never know because our measurements destroy that information.

In other words the information exists but we can't access all of it.

----------------------- *) - One of the important regularities that the formula reveals is the quantization of not only the orbit, but also the wave itself (obviously, the problem of particle/wave dualism disappears at the same time): πr=nλ=(n+n')2r(pl), that is, λ=(1+n'/n)λ(pl), where n' (=0,1,2,3…) is the orbit number, n (=0,1,2,3…) is the number of particles (quanta). In other words, mc^2=ħw; where m (=M/n'=2∆m/n) is the quantum of the full mass (M) and mass defect (2∆m) of the system: moreover, the parameter mλ [=m(pl)λ(pl)=m(w)λ(w)=m(e)λ(e)] covers the entire spectrum of particles. Thus, m(0)=(n+n')m, where 2∆m=nm, M/2∆m=n'/n: on the horizon m(0)=2∆m, M=0. **) - Can be tested experimentally in the laboratory at the moment. {The experimenter needs only two parameters; the mass (gram) of the body under study m(0) and the distance from its center (centimeter) r: so the energy of the quanta of the field ε(eV) ~1.83(m/r); the radiation flux J(Gi)[erg/cm^2•sec]~7.57•10^-27(m^3/r^5). For example: A lead ball suspended on a strong chain from the ceiling of the laboratory can serve as a test body; at radius r=27,6 cm, ball mass is m=1т. The energy of quanta/photons of the field (photons are characterized by different parity and helicity, and it is not quite accurate to say that a photon has an integer spin equal to one) at a distance r from the center of the test body to the detector (practically on the surface of the ball) =66,3 keV. The flow: J*=4,5•10^-9 quanta/сm^2sec; this is a measurable flux for modern world-class gamma detectors.

If the big bang theory is correct, and everything was once quantum, shouldn't all particles and fields in the entire universe be correlated or entangled? If that is the case, doesn't that suggest that whatever instrument or consequence is produced during entanglement could be the foundation of the fabric of reality? Could whatever connects particles during entanglement also be the wave potential of superposition? If you imagine a singularity expanding, and suppose entanglement occurred, the force behind entanglement would have been stretched evenly and uniformly giving rise to a flat space-time. However, that would also leave room to manipulate that fabric in some way.

In that case the wave function would be embedded in a curving space but then the whole caboodle would be embedded in a higher order and more flat space.

Something that I'm not clear about wave function collapse is exactly how it's started and ended. Also would it appear the same for everyone? Like can a particle be in a superposition relative to one thing but not be to another. Also I'm a little curious how entanglement actually works. I always thought it was something like their states are in superposition and they interact in such a way where the outcome of their interaction is a new superposition based on their starting superpositions. So like if 2 particles are in a spacial superposition passing along a path, whether they hit or not would be another superposition. So when you measure and look for the particle at the other end, if it's there they didn't hit and so the other one should be at it's exit or they both hit and scattered. Would that be a correct way of viewing it and the example provided just represents that it can be more granular where it could be that over time a statistical bias happens to show their interacting in some way? Like with the example, I thought that what would be seen would be that when ran close together they would be deflected more than normal and so the beam would have some output in a new position.
