Quantum Theory

Hi Everybody, I'm new here. I'm a writer/film maker doing some research for a story and I thought that this might be a good place to start. I was thinking about a story where entanglement is done on a macroscopic level. I know that this isn't very probable (or maybe even impossible) but for the sake of fiction, please bear with me. I was wondering a couple of things. Can two particles in a system be entangled? Without being entangled to the rest? And if so, is there some sort of mechanism, either theoretical or observed, that could lead to a cascade where all of the particles become entangled? I was reading about an experiment where two pieces of diamond had bec…

Universe is a phenomenon perceived by the observer who not only perceives the former but also affirms its existence & disects its structure. My question is: Can this phenomenon I.e. universe exist in the absence of the observer? Your thoughts?

If you are able to measure the time taken for an electron to move from point A to point B in order to find it's speed, surely you also know it's location at both point A and point B, as these points are where you are measuring the electron passing through.

Hi everybody. My question is strictly theoretical and consists of two subquestions: 1. Is it possible (in theory) to teleport an object (for example a coin) to some point in space where already exists another object (for example a log) and integrate it in it? 2. Is it possible to make it without making any sounds in the destination point in space?

Right now I am 17. I'm graduated, and about to go to community college for 2 years in order to get my basics out of the way to go to a University later. The problem is, I have always been absolutely obsessed by both biology and physics. I don't know which to choose, and I feel like within the next couple of decades it is completely reasonable to do both. Are there any current jobs that require majors in both? I plan to duel major. Ever since I was little I've been really good at math. Just recently have I discovered the benefit to this, and been implementing it. I've read and read about String Theory, Quantom Mechanics, Trans-humanism... Even Biocentrism, which is wha…

Hi all, Recent thoughts have led me to the question 'What is the actual physical mechanism which transmits force between objects?' I'm referring to forces which act over a distance, so electric force or magnetism. I'm familiar with the concept of the electric and magnetic field, where the force is proportional to the distance between the objects. But this doesn't explain how the force is actually transmitted between the objects through space between them. Thanks Dan

I have been watching and reading up on the Higgs Boson, and I was wondering; if the Higgs Boson were to be discovered(it was supposedly found, but not confirmed yet), would it explain why on the quantum level electrons appear to be in two places at once while in the general physical world everything seems to have a specific location that it is located at? (I hope I posted this in the right section).

The best description I have on how the Higgs Boson gives particles mass is from a documentary I recently watched. If higgs bosons were news reporters, and a mass-less particle were president obama, as that particle passed through the Higgs field it would gain mass as reporters (Higgs bosons) crowded around it. While if a particle that was just me passed through the Higgs field, far less reporters would crowd around me. Maybe one or two to ask if I had seen what Obama was doing before we walked into the room of reporters, and so I would gain much less mass. So my question is, what determines how many reporters (Higgs bosons) will crowd around a particle to give it a spec…

So I have one particle in a state of superposition, and two observers measure it simultaneously (somehow), would they both observe the same location?

The wave-function doesn't represent a concrete thing in Nature, it's a mathematical device used to calculate certain things about the Hydrogen atom, such as the energy levels, transition rates, etc.. They can be calculated in other ways, e.g. Heisenberg matrices, or Feynmans path integral method. So when the wave-function 'collapses' it is of no significance whatever, because the system has changed in a way that requires a new wave-function to describe it. The Electron doesn't hide in a 'probability cloud' around the Proton, when it's bound to the Proton, they both cease to exist as single entities and a new entity is formed, the Hydrogen atom, which has excitations…

http://www.space.com/17769-eternal-clock-space-time-crystal.html?cid=co3945404 If this space-time crystal was formed, at the lowest quantum energy state, would it really out-live the universe? The very matter that it is made up of should still be subject to quantum decay, should it not?

Is there any formulations of quantum mechanics out there that are relativistic? i.e. interpretations that take special and/or general relativity into account when describing the behaviour of quanta? As I understand it, traditional QM is not relativistic, time is just sort of "bolted on" and 'ticks away' in the background. I think I recall reading something by Roger Penrose where he said that when relativity is added to the picture at the quantum level, problems arise; something about a particle going its merry way down its own time dimension (?)

Hello all, On one forum I found this link: http://oyhus.no/QM_explaining_many-worlds.html claiming to demonstrate correctness of Many Wordls interpretation of QM. On the one hand - seems like well presented arguments. On the other: it claimes to be discovered in 1990,and it seems to to appear in any peer-reviewed scientific editions.I think: if it REALY is the case - I even didn't come across any apologist of Many Worlds using THIS argument. Any thoughts? Quantum physicists here?

Why does it look like we've hit a dead-end at total comprehension when the solution of a quantum phenomenon lurks under gravity?

hello guys, I'm new here on the forum and seeking information about the behavior of light, for work as 3D artist and the subject interests me. In physics, we have index of refraction when the incident ray crosses from one environment to another refracting light. However, I came to read about ior (index of refraction) for opaque materials such as gold, metal, etc. ... I'm a little confused, could someone help me??? This parameter affects how the reflected ray? Materials IOR http://forums.cgsociety.org/archive/index.php/t-513458.html

I saw this and immediately thought it could be used to transmit information faster than light. This is obviously wrong, but I can't figure out why. Any ideas?

I was just wondering how it worked and related to the quantum world of physics. Anybody care to explain in lay-mans terms? Wikipedia was a bit over my head on this subject.

Sorry if this sounds stupid, does the supposed Higgs field exist now, or could it have been present just after the big bang and imparted mass to those particles at that time? Also how does the Higgs particle get this mass just by interacting, what happens(or happened) to this field, what powers(?) this field?

I am an undergrad currently and am starting my physics class this semester, so I am not as well-versed as a PhD, obviously, but have been studying physics on my own the past three years. I have a theory that requires phD-quality help so that I can continue to shape it... or toss it in the garbage. I cannot mathematically describe this theory yet as it is something completely new and I haven' t had math for physics. Here it goes: It is my firm belief that M-Theory is not a very good candidate for the theory of everything for many reasons. It starts at the high, unobservable, currently untestable energies. The math is elegant in some ways, but I believe they are g…

Why is that in the delayed choice experiment it is argued that the choice of observation in the present decides what had happened in the past? Why cannot it be put down to simply state that the photon in the past, had looked into the future and determined the choice of observation (wether there is a screen or a telescope trained on the slits) and behaves accordingly. The photon could be looking into the future and if it finds a screen it will decide to act as a wave. If on the other hand it finds a telescope pointed onto the slits it decides to behave as a particle.

I wonder sometimes, should this be the quest of Physicist or Biologist? Here is my question: What is the smallest unit of life that is complete on its own, and which forms the building block of all things living? Can it be manupulated to create life or to give life. I know my question isn't acurately framed, but I hope someone understands my question.

Is this real or just some crap on youtube?

An anharmonic oscillator with the potential V(x,y) = 1/2(mw2x2) + 2mw2y2 , How am I supposed to solve this to get position eigenfunctions and energy eigenvalues ?

Does exist the time at very small scales (eg Electrón or Planck scale)? If yes,...does it works in the same way of it do in Our Scale?----Does it goes quickly or slowly?...there is any existing theory about this?
