Mike Smith Cosmos Posted November 30, 2014 Author Posted November 30, 2014 (edited) Scientific claims and evidence. Introduction Neil's Bohr and other scientists at the turn of the century investigated the falling of electrons from a higher energy orbit .to an orbit of lower energy. This was the result of adding ,for example heat energy to an atom . As the electron collapsed from the higher orbit to the lower orbit , it had too much energy to maintain an acceptable lower orbit . The surplus energy was given out from this event as pure energy from the electron . The electron did not disappear but continued to circulate the atom at a lower level of energy . This electron contained charge and movement of charge , both by spin and moving charge , thus developing a magnetic field . So we had all the ingredients necessary to make an energy package . Electro- magnetism , spin, frequency , energy . No particle , because the electron was still in association with the atom . The only thing such a package could work on with this ensemble of ( Electro- magnetism , spin, frequency , energy) was the fabric of space time itself , with all the ingredients as specified by Frank Wiczek in his Nobel Award winning work on ' the grid ' The evidence to prove at least it's existence of this phenomenon is the creation of photons , in the ways described earlier in this thread , namely Black Body radiation by heat or semiconductor / laser , and radio EM waves by a transmission system ( coil inductor , capacitor , frequency driver and antenna ) The exact nature of this photon of energy is the subject of this thread. Evidence to date , is such that the impact of this quantum of energy moves out across space at the speed of light. Nobody to date has clearly specified the appearance of this photon, which appears to exist in the body of space time itself. It is proposed that the simplest self contained shape of such an entity is a three dimensional sphere, otherwise described as a bubble. Very very small with short radius . We believe , that such an effect in space is produced( like a wobbling bubble , but in reality a sphere in its quiescent state ) , but no doubt having more a stretched shape as the sphere is subject to the quality of frequency and spin . The science , is to see if such an effect can produce the questionable effects of the dual slit experiment , and the linking necessary to bring some form of unity to the quantum gravity issue.

Mike Smith Cosmos Posted November 30, 2014 Author Posted November 30, 2014 (edited) I suppose this equation of general relativity ought to be introduced at some stage . Mathematical form. ------------- quote from Wikipedia -------- General Relativity---------------- On the left-hand side is the Einstein tensor, a specific divergence-free combination of the Ricci tensor and the metric. http://en.m.wikipedia.org/wiki/General_relativity Einstein Field Equation is a tensor equation relating a set of symmetric 4×4 tensors. Each tensor has 10 independent components. The four Bianchi identities reduce the number of independent equations from 10 to 6, leaving the metric with four gauge fixing degrees of freedom, which correspond to the freedom to choose a coordinate system. . The equations in contexts outside of general relativity are still referred to as the Einstein field equations. The vacuum field equations (obtained when T is identically zero) define Einstein manifolds. ------------------------ end of quote ----------------- Not that I can cope with it, Einstein used it to produce his image of gravity being this distortion of space time by such things as the masses of planets and stars . However I believe it works even at small scales. My suggestion was ( prompted by various observations as to how energy can enter different mediums in quantised packets. And that the initial projection of energy into the fields was sufficient to make space for a photon's worth of energy to enter the field in the shape illustrated below . Having entered the field under the impetus of the initial energy , the nature of space time , would be to pinch off behind the photon behind one quantum of respective energy . This in effect would repeat the process and project the photon forward at the speed of light , in a succession of quantum jumps. Being in mind that the initial photon has electro magnetic field content, as well as spin content, Mike Edited December 1, 2014 by Mike Smith Cosmos

Is there a gravitational formula that predicts the size of the photon, and also includes the presence of the electric and magnetic fields we know to be present? As the electron collapsed from the higher orbit to the lower orbit , it had too much energy to maintain an acceptable lower orbit . The surplus energy was given out from this event as pure energy from the electron . A photon is not pure energy.

I once read that the statistical rate at which hydrogen fuses to helium ,is no more dense than a warm cup of coffee but the aggregate of 20,000,000/ whatever or so make the sun as roasting hot as it is . However , as I understand quantum ( which seems to cover a multitude of characteristics ) really was significant in the individual Quantum sized chunks of Planck .

( only complete wavelengths permissible, or integer multiples of wavelengths. which of course is responsible for the 'photons ' of light we are discussing.

I remember with some trepidation my university maths sessions to do with field theory, curl and divergence , wave equations, Fourier, Laplace, imaginary numbers in three dimensions , Matrices. But although I could follow most of the maths to do with general relativity, I am too old in the tooth, and rusty to pilot myself through such mathematics to do with these ' tensors' and field equations. I am happy in the regard here , on this issue , that IF nature has demonstrated that the issues of 'Quantum' ' Waves ' ' Spheres , both sold and hollow ' are repeated phenomenon , used by nature , demonstrated by nature, and time tested by nature . then there is a good chance that such hollow spherical mechanisms serve useful functions from the very small to the very large.

Mike, you're putting us in the position of having to comment on something which isn't well-defined. We simply don't know what you mean by "spherical bubbles." It sounds an awful lot like a black hole, but apparently that's not what you're trying to describe. Classically a black hole can be arbitrarily small, and its properties are completely determined by its mass, electric charge, and angular momentum. This sounds directly analogous to the properties of elementary particles (ignoring weak and color charge), which is what prompts some people to think about whether elementary particles can be described as black holes. On the other hand, AFAIK nobody actually believes that particles are really black holes. O.k.

"" They're explaining how Riemannian geometry is used for both soap bubbles and GR, not anything having to do with gravitational bubbles. This shouldn't be surprising either: Riemannian geometry is simply the geometry of curved spaces. The surface of a soap bubble is a 2D curved space. If you're wondering whether or not Riemannian geometry can be used to model electromagnetism (and therefore light), the answer is: yes, but with some issues. It was invented ~100 years ago, and is called Kaluza-Klein Theory. I'll give a quick explanation if you're curious: Basically, the entire theory of General Relativity can be boiled down to two equations: its Lagrangian and its equation of motion (the geodesic equation): [math]\mathcal{L}_{GR}=\sqrt{-g} \, R[/math] [math]m U^{\nu} \nabla_{\nu} U^{\mu} = 0[/math] where g is the determinant of the metric, R is the Ricci curvature scalar (which contains second derivatives of the metric), U is four-velocity and m is the mass of a test particle. The Einstein field equations (which determine the gravitational field) are derived from the Lagrangian, and the geodesic equation tells you how things move when there are no other forces present. Similarly, the entire theory of electromagnetism can be represented by two equations: its Lagrangian and its equation of motion (the Lorentz force law): [math]\mathcal{L}_{EM} = \frac{1}{4} \sqrt{-g} \, F^2[/math] [math]m U^\nu \nabla_\nu U^{\mu} = q U^{\sigma} F^{\mu}_{~\sigma}[/math] where F is the electromagnetic field and q is the charge of a test particle. Maxwell's equations are derived from the Lagrangian, and the Lorentz force law tells you how things move when only gravity and electromagnetism are present. Kaluza realized that if you postulate a tiny "curled-up" fifth spacial dimension, and if you construct the 5D metric in particular way, then something magical happens. By analogy with gravity in 4D, we define a 5D gravitational Lagrangian as: [math]\mathcal{L}= \sqrt{-\tilde{g}} \, \tilde{R}[/math] where the tildes above g and R denote that they are the 5D versions. The 5D metric is defined as: [math]\tilde{g}_{AB}=\begin{pmatrix} g_{\mu \nu}+\phi^2 A_\mu A_\nu & \phi A_\mu \\ \phi A_\nu & \phi \end{pmatrix}[/math] where the capital Roman indices run from 0 to 4, Greek indices run from 0 to 3, [math]g_{\mu \nu}[/math] is the usual 4D metric, [math]A_{\mu}[/math] is the electromagnetic potential, and [math]\phi[/math] is some constant (technically it's a scalar field). If you work out the determinant of the 5D metric, you find [math]\tilde{g}=g[/math]. If you work out the 5D Ricci scalar with this definition of the 5D metric, you find: [math]\tilde{R}=R+\frac{1}{4} F^2[/math] So the five-dimensional gravitational Lagrangian becomes: [math]\mathcal{L} = \sqrt{-g} \left (R + \frac{1}{4} F^2 \right ) = \mathcal{L}_{GR} + \mathcal{L}_{EM}[/math] Almost miraculously, 4D gravity + electromagnetism seems to pop right out of the definition of 5D gravity. Similarly, if we work out the 5D geodesic equation, we obtain the following two equations: [math]\xi \equiv U^4 + A_{\mu} U^{\mu} = const.[/math] [math]U^\nu \nabla_\nu U^{\mu} = \xi U^{\sigma} F^{\mu}_{~\sigma}[/math] The first equation tells us that there is some conserved quantity having to do with motion. The second equation looks startlingly familiar to the Lorentz force law. Indeed if we identify [math]\xi = q/m[/math] then the two become equivalent. Interestingly, this gives us a definition of electric charge: [math]q=mU^4 + mA_{\mu} U^{\mu}[/math] Since U4 is the velocity through the extra dimension, we associate charge with a particle's momentum through the extra dimension. Kaluza-Klein theory has a lot of problems though. For example: the size of the fifth dimension should be unstable, which should cause it to blow up and become macroscopic. It also predicts a so-far unobserved scalar field. The theory can't be made quantum mechanical either, because it includes General Relativity as-is. **Note that I've cheated a bit in places. For example I set [math]\phi=1[/math] for simplicity, and I've assumed the fifth dimension is too small to have a significant effect on the 4D motion of objects. Edited December 2, 2014 by elfmotat

It was invented ~100 years ago, and is called Kaluza-Klein Theory. And just as a remark, you can generalise this to the non-abelian case also. You can also play similar games on supermanifolds. I am not sure if that would be a reasonable way to introduce fermions into KK theory...

This bit is the bit we need to test. In a moment. The photon then reaches the end point in its destination where it interacts with another atom , say an electron absorbs the photon of energy etc and is excited to a higher orbit. This bit we know. Back to the bit in the middle, the test . We look in on the photon half way through its journey and see what we see. ...Observe. ... But that is precisely what we do with the double slit experiment! What happens the photon wave function collapses. We see particle type behaviour , in other words we have brought the end destination forward, we have broken the bubble in the metric and we are with a burst bubble with normal photon electron interaction. Now I appreciate this is a little like picking oneself up with your own bootstraps , but none the less, this particular simple test, has been survived! And contributed to the wave particle duality/ double slit experiment in the process. Mike Ps I am in the middle of Exeter delivering some paintings , so you may not get an immediate response, .

Mike Smith Cosmos Posted December 3, 2014 Author Posted December 3, 2014 Yes, I think that's possible; I'm not the only one to say that it sounds like you're describing a black hole. What I have been asking you is to give the answer, instead of repeating that there is an answer. because I don't think that a photon at the sodium wavelength, which has an energy around 2 eV, is going to give you anything close to a 1 micron bubble. The main reason i have not jumped at the ' black hole ' that a couple of you have suggested ,is that although i accept that this can be very miniature, I associate black holes with concentrated, relatively large amounts of mass in say a singularity at its center , and again being an entity, particle of thing separate from the metric or grid , rather than as I am proposing , the energy, mass ,spin , momentum and rotating electromagnetic field , becomes part of the metric , is injected into the metric to become this bubble , which unless interrupted, will set up a chain , of internal energy transferring bubbles , like collapsing domino's , off into the distance at the speed of light. mike Mike, you're putting us in the position of having to comment on something which isn't well-defined. We simply don't know what you mean by "spherical bubbles." It sounds an awful lot like a black hole, but apparently that's not what you're trying to describe. Classically a black hole can be arbitrarily small, and its properties are completely determined by its mass, electric charge, and angular momentum. This sounds directly analogous to the properties of elementary particles (ignoring weak and color charge), which is what prompts some people to think about whether elementary particles can be described as black holes. On the other hand, AFAIK nobody actually believes that particles are really black holes. As I said, this sounds an awful lot like a black hole. A BH with a mass energy as small as you describe would have an event horizon ~30 orders of magnitude smaller than the Planck length. They're explaining how Riemannian geometry is used for both soap bubbles and GR, not anything having to do with gravitational bubbles. This shouldn't be surprising either: Riemannian geometry is simply the geometry of curved spaces. The surface of a soap bubble is a 2D curved space. If you're wondering whether or not Riemannian geometry can be used to model electromagnetism (and therefore light), the answer is: yes, but with some issues. It was invented ~100 years ago, and is called Kaluza-Klein Theory. I'll give a quick explanation if you're curious: Basically, the entire theory of General Relativity can be boiled down to two equations: its Lagrangian and its equation of motion (the geodesic equation): [math]\mathcal{L}_{GR}=\sqrt{-g} \, R[/math] [math]m U^{\nu} \nabla_{\nu} U^{\mu} = 0[/math] I wish I could spend a fortnight , sitting down with you and going through this math with you. I worry that you may tire of me , with my constant referral to similarities in other areas of nature. However I am heartened , by the fact that others are looking at spherical structures in some way. Unfortunately i have left my wilczec book over in Italy , as he speakes of EM waves being present in the metric and grid . mike And just as a remark, you can generalise this to the non-abelian case also. You can also play similar games on supermanifolds. I am not sure if that would be a reasonable way to introduce fermions into KK theory... Ajb perhaps you could elaborate slightly .

This is why you need to have an actual model, because this hand-waving doesn't actually convey any useful information. How else do you get curvature of spacetime, other than by having a large amount of mass (or energy)?
