mistermack Posted August 8, 2017 Posted August 8, 2017 Electric and magnetic forces are action at a distance? Not really. They are action over a distance and time. The action takes time, even if it is fast. Not so different from throwing a stone. You throw the stone. Time elapses and the stone travels. The window breaks. So I wouldn't call it action at a distance. It's action...-process over distance and time....-reaction. How that jumps to there being a god hasn't been explained. Why can't the laws of physics exist without a god? Just claiming that it is so isn't very good logic. Logic involves explaining how you get from one statement to the next, and why it has to be so.

Yes there is models that try to replace the two but when answering posts it is vital to make sure your responses are accurate and non misleading. Try not to take corrections personally, in many cases its not the models your referring to but how you are describing those models that needs improving. Use the opportunity to learn why you are being corrected. You will find that no one objects to spinfoam or quantum foam. Rather they are correcting how you are applying spinfoam in your descriptives. Accuracy is extremely important when replying to threads. For example LQC avoids the singularity issue by applying effective cutoffs called the IR and UV cutoff bounds. IR is your minima UV is the maxima. They avoid any infinities by using these cutoffs in their mathematics. However those same cutoffs allow the renormalization of spacetime. However as we cannot quantize gravity we still have renormalization problems. LQC doesn't provide an answer to this problem but is still working on it just as every other related theory is also doing. Fundamentally LQC is fully compatible with LCDM, with the exception that LCDM doesn't address how the universe started as it is no longer accurate prior to 10^-43 seconds. LQC doesn't address this problem either except for applying the cutoffs and having the bounce avoid the singularity issues due to infinities. In other words LQC doesn't solve the singularity issues it avoids them with renormalization cutoffs. Which is in essence the renormalization problem inherent in quantum field treatments. With the electromagnetic fields we know photons are discrete, we have yet to confirm this is true with spacetime itself. Every attempt to show that spacetime is lumpy (discrete) has shown it is smooth as in not discrete. ( a means to learn the cutoffs in QFT treatments is to study Observable operators and propogators which are not observable. To be observable requires a minima of a quanta of action. The effective maxima in QFT is the Planck temperature. https://en.wikipedia.org/wiki/Planck_temperature Relativity doesn't apply these cutoffs and won't until we solve the quantizing of spacetime issue. Though even if the cutoffs eventually get accepted as accurate relativity will still work as accurately. Within the range of cutoffs, that is the issue. Where do we establish the range where where a metric remains valid and when does it become invalid due to infinities. Spinfoam doesn't address this issue as a spinfoam uses operators in its renormalizations for each Hilbert space. In other words the external lines on a Feyman diagram. The internal lines being your virtual particles or fluctuations as opposed to an excitation. To get a better handle on this read http://www.scienceforums.net/topic/106004-useful-fundamental-formulas-of-qft/ I go into extensive detail on the operators vs propogators though I haven't done the path integrals for Feyman diagrams as of yet. (Still trying to figure out how to simplify) I take nothing personally Thank you for taking the time to reply, contrary to popular belief I am learning. I have problems believing in gods, singularities, time travel, and a single big bang as the origins of all matter in the universe. I also have problems with gravitons radiating from particles in black holes for instance causing things to be pulled in. A contraction or absorption of space towards a mass seems more logical rather than a particle transmitting a force. Quantum foam fits this idea I think, I still need to study your links above, and I need some time to really sit down and get to grips with it. Matter when it is compressed is heated and eventually breaks down and can decay into antimatter and matter. Black holes emit gamma ray bursts, which may be due to this process. The concept of a single big bang giving rise to all the galaxies in the universe, seems a little bizarre. There lots of galaxies assumed to have black holes at the centre. Supernovae maybe a small version of a big bang but driven by matter antimatter collisions. If each galaxy has a black hole in the middle, then it is possible that the contraction of space in a galaxy in the black hole results in a big bang which starts the whole process over again of recreating galaxies, a kind of rebirth or recycling,(this is the religious forum). Martillo's deist idea of god interested me but lacked range, and clearly he was going to lose. The religious folk on the forum don't put up much of a fight and get mawled regularly I thought it might be interesting for him to try quantum foam as an Omnipresent Deist god, rather than a magnetic or electric field I tend to think in pictures, rather than maths or words although I do get by in multiple languages including maths, but like all languages if you don't use them you get a bit rusty. High level maths is like Latin spoken by priests, which few people understand. Good luck with the simplifications.

I just gave my thanks for all posted opinions in the thread even if all were disagreeing with my proposition on the OP. I appreciate all criticism but I didn't say I changed my mind or abandoned my idea. Is just that I could perceive that I would get no constructive income and so it doesn't worth continue the discussion. By the way I don't think in a "Omnipresent Deist god" as some "electromagnetic foam" as you seem to say I do. The "God" I think does not have omnipresence nor omniscience nor omnipotence for instance. It is deistic, it had the capability to create and run this Universe we live developing the "Universal Supra-computer" that runs the physics laws over all the particles created in it. Of course he knew the kind of worlds and living beings that physics and particles would produce. But it doesn't worth to discuss anymore. Edited August 9, 2017 by martillo

My post ref the quantum foam was intended to give Martillo a leg to stand on, otherwise his argument ref his god definition was destined to lose. I don't have dissatisfaction with mainstream science, just so long as what is talked about keeps up with newer ideas, and does not hang on to some ancient ideas like a hand reaching out from the past, like we see in some religions. As I have pointed out science is not meant to be based on religious belief or attitudes, I know this annoys the crap out of you. You have spent a long time being wrong in many of your posts to me, get over it and move on. The following competition will annoy you as well, but others may be interested in the possibility of a competition on gravity, by the gravity research foundation ($4000 prize1st prize) https://www.gravityresearchfoundation.org/ requesting a 1500 word essay on gravity. Your insistence on a smooth space time, and space being an empty nothingness, most likely is going to be laughed out like the flat earth society. Gravity is caused by a flow of space and all waves and forces passing through space are affected by it. Just accept it, like a grown up. Quantum foam fills all of space, without which there would be no gravitational forces space or nothing. You could even go so far as stating quantum foam is a form of the ether, which I originally annoyed with for amusement. Happily for you I have moved to another forum, due to fake advertisements and fake scientists acting as moderators. I can learn more via google and up to date science books than putting up with your crap. Kind Regards and best wishes with your future. 2018-competition.pdf -2

Electrical Engineering at Unicamp University - Brasil (in the four best of latinamerica). Quote Quantum field theory is a xtremely well supported by experiment. You seem to be confusing your ignorance for a problem with a physics. From "Virtual particles" at Wikipedia: Quote The term is somewhat loose and vaguely defined, in that it refers to the view that the world is made up of "real particles": it is not; rather, "real particles" are better understood to be excitations of the underlying quantum fields. Virtual particles are also excitations of the underlying fields, but are "temporary" in the sense that they appear in calculations of interactions, but never as asymptotic states or indices to the scattering matrix. The accuracy and use of virtual particles in calculations is firmly established, but as they cannot be detected in experiments, deciding how to precisely describe them is a topic of debate.

The proof of the existence of a deistic "God" follows quite obviously: Some kind of "Superior Intelligence" must have 1) built the “Universal Supra-computer” machine, 2) programmed the Physics Laws in the machine and 3) setted the numerical values of the parameters of the Physics Laws. That "Superior Intelligence" can be called the "God" of the Universe in its deistic conceptualization (http://en.wikipedia.org/wiki/Deism). So there is no other known way the universe could work?

I do not understand why you would assert loaded statements like Quote Well, I will ask why Science would not consider the possibility of a "Universal computing system" running the Physics laws over the elementary particles. Complete lack of evidence of such a Universal computing system not to mention no need for such a system would be reasons to be sceptical of an Universal computing system asking why "science would not consider the possibility of a Universal computing system" is deceptive to say the least and suggests you have an agenda that is less than honest.

You may ask why to do so? I would answer with the following page: Quote REALITY IS HARD All kind of deseases, calamities, catastrophes and tragedies... We don't live in any Paradise. But not being human beings fault, what fails is the Physics of the Universe what I argue at the web page: A Physics' flaw The Physics of the Universe determines everything material and the entire Nature itself including our own organism. Failing, the things are not as they should be. And in this are all of us, living a wrong life from which nobody scapes. What remains for us is try to live the better possible way doing what we know and could do that always, in one way or another, ends being something others are needing. Nothing else remains. And as I say at the web page: _ "Hope would exist if some "Superior Intelligence" would exist, responsible for the Universe Physics System and capable to fix it. But it and its systems could also have been affected by their own Physics' problems and so not being able to think and work properly..." _ "May be we, all humans at Earth with all of our developed knowledge, technology and our imagination, could be helping someway just following our intuition.

Manticore Posted August 11, 2017 Posted August 11, 2017 To prove that there exists only one god, you have to show: 1) The Universe is not infinite (since in an infinite Universe there must be either zero or an infinite number of them - depending on whether they can exist at all). 2) Faster than light communication (if you assume that your god can think as fast as the average home computer, then, with the speed of light as a limit, it's maximum possible size is 5cm in diameter - assuming no processing delays). -1

Of course that computing system would be in a scale not even imaginable by we humans but this must not be a constraint for it to be possible. Edited August 11, 2017 by martillo
