Quantum Theory

From what I understand, hawking radiation is when two particles are created, either by a photon momentarily splitting into an anti particle-particle pair, or an antiparticle-particle pair being created out of nothing (within the limits of the Heisenberg uncertainty principle). One of these particles falls into the event horizon and the other doesn't, so one particle is created out of nothing and the black hole loses a small amount of mass (black hole evaporation). This seems to me to be a little dodgy, it seems like quantum mechanics is being tricked. And as we have learnt from many many experiments, it cannot. For example, light from distant stars, coming in as a par…

With multidimensional explanations of reality today, things we know may need to be looked at again. I've always been bothered by the concept of EM waves oscillating in two dimensions. The expansion of the view of EM waves to include a 4D aspect has some interesting implications. A 2D EM sine wave may only be the portion of a 3D EM wave that intersects with our 3D reality, in only 2 of 3 dimensions. Picture a photon orbiting the axis that is the propagation direction, as it travels. This would form a 3D helix, that when viewed in a 2d frame would be seen as a sine wave. The radius of the orbit would be the sine wave amplitude. The time required for for each orbit wo…

Ok. Take a bosonic propagator. Or a Green function call it as you wish. Know what I mean, huh? The solution of ([] - m^2) D(x-y) = - delta(x-y). It's something like D(x-y) = integral over d^4p of exp(ip(x-y)) times 1 / (p^2 - m^2 +- i epsilon) Now. First of all, I don't want to bother about prefactors, "i" factors, signs, prescription (feynman, casual...) The point is. I have seen this expression so many times. (and actually NEVER used it, I'm not a scientist). Then suddendly I realized that... that... ...isn't it INFINITE?! Ok forget what happens on the poles. But we are talking about an integral over "p" in 4 dimen…

Mr. Pi, Kewei (China) The press conference hosted by the European Organization for Nuclear Research (CERN) on July 4 announced a newly discovered subatomic particle, which could very likely be the Higgs boson that is generally known as "God Particle". This discovery ecstasizes many physicists who are firm believers of Standard Model Theory, and they consider this moment the true triumph for this Theory. However, is what they believed really true? With the appearance of a new particle, the question whether it is a "God Particle" depends on whether it is a boson, whether it falls under the mass scale and certain quantum values, and most importantly, whether i…

Hi guys, I am new to this website and have never interacted with sites like this before, so I hope you break me in gently I have not been to collage or uni and didn`t even do that well at school to be honest, so I don`t speak the science languages. Though I believe you don`t have to know how something works to understand it. I have always had a fascination with the universe and have come up with many theories, but I have always reverted back to the big question(s): What is beyond our universe and how did it begin? I`m sure this is the one that no person can answer with hard evidence. I have finally come up with my own theory that may co…

hi, does anybody know what kind of charge the "q" stand for in the higgs mechanism? I mean the mechanism between the weak force mediators: W & Z, and the higgs boson, which leads to them acquiring mass. I've learnt about it from the text book by David Griffiths "Introduction to Elementary Particles". There in section 10.9 (2nd addition) or 11.9 (1st addition) he introduces the "q" along with the covariant derivative (first stage by Weyl to transform the Lagrangian into an invariant under local phase transformations), which leads me to consider it being the charge of the weak force, as…

The Benzene Molecule This is a description of the 'other kind of bonding' that occurs in Nature, resonance bonding. We all know about Coulomb bonding, the type that is determined by electric charge, and which holds the electrons to the nucleus. Resonance bonding ( RB ) is purely quantum mechanical in its working, it has no classical equivalent. It's very important in Chemistry, but it's important in another way too, for it holds the nucleons together in an atomic nucleus. The requirements for RB to occur are simple and easily met in Nature, so it is a frequent occurence. It needs: Two states with nearly the same energy, which can change back and…

Hi all. I'm new in this forum Please,forgive my no very good english Quarks and tachions share the feature of be: ¿Unobserved? ¿unobservable? Could an ultrarelativistic (tachionic) model of quarks to describe some features or behavior of quarks? Why a tachion has negative energy in the context of SR? How could this model be contrasted.? That is :how could it be designed an experimet "falsabilizante"? i Thanks: health, peace and good luck. lanjarote

>."OBSERVED"< . how does the observing of a particle happen in here exactly? If we look at a mobile phone,light electrons hit the phone and return it to eyes.like that how does the observation of a particle happen(so it collapses the wave function!)?

In EPR gedankenexperiment the first object that destroys the coherence of photons is the semitransparent mirror. In particular the non infinite mass of mirror induces a frecuency-energy doppler shift in the reflected photon. ¿Do you think that it worth to model such effect and incorporate to the gedankenexperiment or it would be only noise?

Author: Alabi. vol 7, (2012) http://www.iiste.org/Journals/index.php/APTA/issue/current Interestingly... we can now generate quantum numbers, have a choice mechanism, retrieve information from black holes and eventually the shape of the universe can be a cone.

At the link below, I derived quantum Theory from logic alone. http://webpages.charter.net/majik1/QMlogic.htm The Feynman path integral of quantum mechanics is seen as the mathematical representation of a similar construction in logic. Paths in logic are constructed as the conjunction of many implications, where the consequence of one implication is the premise of the next implication, forming steps through what appears to be paths. Any implication can be equated to the disjunction of every alternative path from the original premise to the original consequence. Then I show how implication is represented by the Dirac delta function. This then r…

If Planck's Constant tells us the minimum amount of transferable energy does this mean also the smallest size thing, or smallest area of space? Is a photon the same size as a neutrino? Or does it have less energy then a photon? --- It strikes me that if one can speak of this quantum in terms of area, that there are smaller bits in a state of useless entropy that are bellow the threshold of what can be agglomerated in such a way so as to do effectual work.

I have two questions What is the minimal quantom of energy in the universe? and How and who established it? Are there theories that predict that a lower level of Quantom might exist and will be discovered/validated in the future?

I am not a physicist. I don't begin to have the math aptitude to become a physicist. But I think about it a lot, from a philosophical perspective. I read in the news recently about a method for generating fairly large numbers of entangled particles. Here is a link to a New York Times article on the topic: Billions of entangled particles advance quantum computing. Because the entanglement does not require that the particles be anywhere near each other, doesn't that make it possible to use entangled particles to transmit information instantaneously and therefore, faster than the speed of light?

In quantum entanglement (QE) experiments, two or more simple quantum systems (fundamental particles, e.g. photons & electrons, q1, q2) are "mingled", into a single composite quantum system (Q), which exists only in an insubstantial "quantum state" of "incorporeal ghostly ambiguity": Q ~ q1(left) q2(right) + q1(right) q2(left) When the composite system undergoes measurement (M), imposed upon it by an external agent (human scientist), the composite system randomly "decides" which substantial "classical state", of "corporeal certainty", to "collapse" into: Q ----> q1(left) q2(right) ("the first photon went left, the second went right") or ----> q1…

I'm thinking black holes and stuff. Sorry I haven't really got any idea about any of it, I just find it really interesting after seeing a program on TV last night about black holes. Thanks.

LIGHT We do know that photons behave like a wave and a particle both, that's what particle wave duality tells us.. 1)So which source of light behave likes a particle and which one like a wave, How do we know that?? 2)If a particle has larger wavelength it behaves like a wave and the one which has smaller wavelength behaves like a photon? 3)Photons have momentum, p=hv/c, do wave have some momentum? Electrons Electrons are present around the nucleus of an atom(we all know that) 4) Are they present there as particles, standing frequency, clouds or on orbits(which is the least i would prefer) ??

What collapsed the first wave function?

http://www.imdb.com/title/tt0499596/ This is a Quantum mechanics documentary movie. Has anyone watched this? is that true thinking effect randomness of random number generator machines , and positive thoughts(love,thanking) ,blessing of a Buddhist monk changed water molecules' structure? they say there are scientific proof. wow! all of the people who said these were physicists

I decided to quantize Newtons 2nd Law [math]-kx = \frac{\partial P}{\partial t}[/math] today. Has anyone done this before? I need some help. I start with quantizing the equation, naturally; [math]-i \hbar \frac{\partial}{\partial x} (\frac{\partial}{\partial t}) = -kx[/math] Hitting it with a wave function [math]\Psi = \psi(x)\phi(t)[/math] gives [math]-i \hbar \frac{\partial}{\partial x} (\frac{\partial \phi(t)}{\partial t}\psi(x)) = -kx \psi(x)\phi(t)[/math] To solve it we are therefore going to use the separation of variables method. (But I need you guys to make sure I am doing this right) Divide through by [math]\Psi[/math] gives …

Hello. Could somebody answer this question I asked on http://www.physicsforums.com/ "There is small question how electromagnetic field can be explained by virtual photons. The problem is that photon itself is electromagnetic wave. So electromagnetic field of virtual photon itself could be made of another virtual photons. And fields of these virtual photons could be made of another virtual photons again. And so on. So we have infinite logical recursion. Do not looks much realistic. " I mean if virtual photons exist they exist independently from QED like all other real phenomena of the Nature. So it can be seen also from classical view point as usual but very …

what is wrong with my calculations? These are just any numbers here... google calculator 0.104384134 * 9.58 = 1 Calculateforfree.com / Online Calculator http://www.calculateforfree.com/sci1.html 0.104384134*9.58 = 1.00000000372 I know about rounding off, but do calculators perform differently?? thanks

hello, what are the best links and or books for someone whom would like to be introduced to dimensional analysis "basic level?" What I would like to find is the position of the electron, please don't laugh, I think it is possible... thanks for your help....
