Quantum Theory

Could it be possible that dark energy and dark matter are just two dimensional?

does light (photons etc.) pop out of existence, then return, at the same location and still travelling in the same direction? I note articles saying photons do pop into existence enough to be visible, tho no mention of duration of the light.

I'm sorry, this will be my last question for a while, I promise xD. I'm currently reading through a book of the history of quantum physics and got to the Ultraviolet catastrophe, which as i'm sure you know was when classical physics predicted an infinite energy/wavelength light. I believe that's what it is anyway What I do know about this subject is 1. In the classical interpretation, the intensity would keep increasing as long as the blackbody keeps receiving energy and the wavelength would keep going down forever. This would create a very high intensity higher than ultra violet ray, correct? 2.I don't understand the quantum view though. Why does a blue light …

can you let me know the heisenberg's uncertainity principle in spherical coordinates or atleast share a link from which i can get it

Can two photons occupy the same space, as they do not have a mass? Can a photon affect the spin of an electron, if it is absorbed? Do photons of different energies or wavelengths affect electrons differently? Thank you.

Is all matter infinite? Is matter impossible to take out of existence? Does matter change state at quantumn levels? Is light a form of matter? If all is infinite, what is the need for time? Can all these questions be statements?

Pressurized hydrogen is known to leak through its container due to its incredibly small size. Why is it that photons being much, much smaller than hydrogen atoms cannot shine or "leak through" solids/ containers? Just for comparison of size between hydrogen atoms and photons: hydrogen atom mass: <1.0 x 10^-26g photon mass: <1.0 x 10^-35g -EE

is it correct to say that during motion of particle a temporary rider particle with dual nature is created while initial permanent particle exhibits particle like nature only ? By temporary particle i mean a wave packet where energy pumped in during imparting motion to the particle is accumulated,therefore it is not particle in normal sense but has got dual nature.

It is not long since I was reading about photoelectric effect, and some interesting questions impressed upon myself, which I will be obliged if you answered in a simple manner: 1. Okay. Photons transfer energy to electrons and they, in turn are ejected following certain rules. But what happens to the photons which gave (all?) of their energy? Do they just lie dormant there? 2. Where I was reading, it was all about electrons. But can photons wrung out protons, neutrons, etc. too? If so, then are they capable of causing subatomic particles to dissect into their components too? 3. Last of all, are photons pure energy or kind of particle-energy entities? Thanks.

We know that the weak nuclear force has two charged bosons: W+ and W- All charges give out photons (bosons of EM force) So do the charged bosons of the weak nuclear force emit its own bosons? Im new to this concept. Please provide an elaborate explanation...

Should the [current] inability to "measure" position and momentum mean that a particle at a moment in time does not have a given position and speed?

When we do experiments with electric fields, we do this by building up an excess of electrons. This means that such experiments tell us about the electron’s electric field, rather than also the proton’s electric field. Therefore, when we do experiments with light and electric fields, these experiments are only finding out about how light interacts with an electron's electric field. These experiments show that the light is not affected by the electron's field. Physicists have concluded that light does not interact with electric fields, whether that field be from an electron or a proton. But what SHOULD have been concluded: Is that light does not interact with t…

>Has the controversial double slit experiment (using electrons ONLY, NOT photons) ever been performed in temperatures close to absolute zero and near vacuum conditions? If so please list the observation (Phenomenon such as self-interference, waveform collapse etc). If not, please mention the expected results; Please emphasize on the ones that are expected to deviate from our current typical observations. >If a photon has an independent electric vector and magnetic vector... Shouldn't there be an independent gauge boson for charge and magnetic polarity on a very small scale?(Significant to the size of the photon) Wouldn't this mean that there are more than 4 fund…

Anyone care to speculate?

These are all questions about light, so I figured it would go here? First off, I've heard that perpendicular electric and magnetic fields create EM waves, but why is that? what happens that forces those waves into existence just from perpendicular fields? Also, since light is an EM wave, does that mean that it is also created from these fields? Because when I read about light, it was always said to be created when electrons jump around locales. Also, not related to this subject, I'm rather new to physics and I've read a few books on quantum theory and enjoyed them, but, as I read through some of the topics on this forum, I was completely lost. May I ask if this …

How and why does measuring a particle make its wavefunction collapse, producing the concrete reality that we perceive to exist? The issue, known as the measurement problem, may seem mysterious, but understanding of what reality is, or if it exists at all, hinges upon the answer. Thus can physics anwer this question yet?

Is it possible to jump off a roof of a building then land on the same roof?

Is frequency the number of oscillations every second or the number of wave crests that pass every second?

Alright, well, this is somewhat of a continuation from my previous topic. I'm new here so I wasn't sure if it would be better to post a new topic or just edit my previous topic. I figured that it would be better to make a new topic as it's a topic change, if it's incorrect or against the rules, please delete this topic and let me know. xD anyway, before I get into a lot of detail here, keep in mind I'm only in high school currently. I'd love to enter a field in quantum physics, but I would imagine it would be incredibly hard without tons of experience. I just want to plan for the future and try to set a path ahead of me. well, I'm greatly interested in quantum phy…

I am reading a book on an introduction to quantum physics and I came across what appears to me as two conflicting statements. I believe it said that a single photon cannot have enough energy to knock loose an electron due to the fact the the photon is quantized. Yet a few pages after this the book claims that "The energy necessary to knock loose an electron is provided by a single photon in an incoming electromagnetic wave". So which statement is true?

The stopping voltage is the voltage that one would apply to stop the electrons from migrating to the cathode. My quest is what purpose does this serve and what does the stopping voltage tell us?

QUANTUM ENTANGLEMENT OF TWO DUMBBELLS To reproduce Quantum Entanglement with two dumbbells this is what you need to do, Fire the two 12 inch dumbbells in synchronized rotation at two equidistant cardboard targets with 8 inch holes in the center. If one target is destroyed the other one will also be destroyed. If one dumbbell passes through the hole the other dumbbell will also pass through the hole.

Assume entanglement really exist. then it's easy task too create a Quantum morse code device. when tested with several hours of light speed distance. now some hypothesis. if a code is send but without conformation at the receiver, probability still exist. the received information travels back at speed of light too the sender. *entanglement exist* but if the receiver send a massage right back to the sender, will Quantum entanglement cancel out? no room for Probability. so will entanglement cancel out in this scenario?

Hello All, Recently I came across F.Tipler' paper(who is famous MWI supporter) arguing that non locality can be used as the evidence for the multiverse. Here is the abstract: "I show that observations of quantum nonlocaltiy can be interpreted as purely local phenomena, provided one assumes that the cosmos is a multiverse. Conversely, the observation of quantum nonlocality can be interpreted as observation evidence for a multiverse cosmology, just as observation of the setting of the Sun can be interpreted as evidence for the Earth's rotation." and here is the paper: http://arxiv.org/pdf/1008.2764.pdf I am personally not fan of MWI,therefore the question is if …

What is E in schroedinger equation Is it energy of whole atom or energy of electron only?
