Modern and Theoretical Physics

Alright, so I am not a theoretical physicist, but one of my physics buddies and I had this idea today and I wanted to run it by experts to see what out error in thinking is. Heres the concept... What if light was stationary in the universe, and we were moving through it? This would imply that light was somewhat of a 4th dimension, and our observable world was traveling through it at the "speed of light". This would also imply, I suppose, that time would not be the 4th dimension, but a characteristic of matter like gravity? which would say that time does not exist in the absense of matter. The concept of stationary light/moving universe would also explain the constant-…

happy if anyone can help or maybe tell me where i can get some inspiration

Does anyone here know a good review article about graphene and in particular the electronic properties? I know that the effective low energy theory is described by a two dimensional massless Dirac theory with an "effective speed of light" about [math]10^{6}ms^{-1}[/math]. I am interested in the effective gauge fields due to defects, the similarity with quantum field theory on curved backgrounds and the use of supersymmetric quantum mechanics. I know little about condensed matter physics. (I should have paid more attention at school) Any suggestions of reviews welcome.

I have been looking through the limited available electromagnetic books I can find for the Heaviside curled EM energy flow component, and I can't find it, at least I think they don't put it into textbooks. Does anyone here know what the equation looks like?

Hi everyone, I joined recently and I'd like to share some things I've written with you. I think they might be of interest to some people. This is a presentation on carbon nanotubes that I made three years ago. They are fascinating things. The presentation should suffice to give a good overview of nanotubes. If you want to make any corrections, comments, or additions just tell me and I'll make some changes. Three years ago I asked to visit the Cambridge nanotube lab but the professor was away at conferences - I might ask again sometime soon The best way to view the presentation is to start the slide show from the beginning and click through it (rather than rea…

I'm new here and have little education. Everything I know was self taught. So I apologize for my simpleness and lack of understanding upfront. So I have been reading and trying to understand various things I find interesting and I finally combined two of these ideas in my head and had my little Epiphany awhile ago. I'm sure this has been discussed many times but I just put this together and will try to relate as best I can. I'm not a master of the written word and sometimes it's hard for me to put thoughts on paper, but here it goes: I don't believe an observer "effects" what it observes as explained here: http://www.sciencedaily.com/releases/1998/02/980…

Could someone please explain the direct method used in weak measurement, and what are its implications. The relation between weak measurement and Hardy's paradox. I have tried to look in to the subject and see its connection to the double-slit experiment and how the act of observation can affect the result of this experiment.

I guess this is rather a philosophical question than a real physics/mathematics question. If we assert that fundamental matter particles are always fermions and that forces are always mediated by bosons, or at least within the standard model, then should the Higgs be considered as matter or as a force? My own through is that it is really neither and should be dealt with carefully when trying to assert matter <-> fermions and forces <-> bosons. Then when we introduce supersymmetry the situation is even more mixed up, but lets not get ahead of ourselves. So, do you think of the Higgs as matter or as a force, or as something else?

I was wondering, when considering the existence of the multiverse, is it possible for 2 or more universes to collide or more so interfere with each when expanding in proximity to one another ?, and could this be a possible explanation for the rapid expansion of our universe, in terms of gravitational/space-time waves from multiple (universal) expansions intersecting with each other. Thereby producing some sort of constructive amplitude in space-time and causing an increase in expansion rate. Also, could this explain dark energy in terms of some sort of energy produced from inflatory processes at difference points in space-time and in a sense leaking some sort of external …

Is there any evidence for the existence of an antiphoton? Or an antimatter version of any of the other force-carrier particles?

ajb once told me that gravity is it's own anti paritcle. This makes perfect sense. But doesn't that mean that gravity can be both an attractive force and a repulsive force?

I'm just curious to ask ... Since light is photons, I have some questions .. 1. Is the photon speed the same, among all photons ? 2. does the photon have any properties, like particles ? 3. In classical physics I learned that light is just waves, in modern physics it's a photon .. where is the difference, where are we exactly .. matter, wave, energy ? .. thanks

I've heard photons described as electro-magnetic waves, waves of momentum, pure momentum, pure energy, etc. But with mass, matter carrier of mass, but there is suppose to be some particle that causes mass and causes a distortion of the fabric of space? So, is there a principal particle that comprises photons, or are photons pure energy? In which case, why can't we just say energy is an actual substance?

Hi, i was wondering what the property is which gives or allows 11 dimensions in m-theory.. (is it a natural property of the theory itself or something external)

The newest experement in RHIC (american collider) provided te temperatures of collisons .In that collisons gluon plasma created .But the temperatures were very low than an explosion , or a chaotic collison . What make the deference ? I believe that the existence of gravitation force keep so low the temperatures. http://nalxchal.blogspot.com

Perhaps time dialation is the key to proving string theory, or Mtheory. Maybe faster than speed of light velocity causes these strings to expand. Heat expands atoms. Maybe these strings have a rest state that is excited by movement, after all these strings are supposed to be gravity, and isn't gravity all about weight and momentum?

Hi all, I am looking for any material (mainly books) on String theory/Brane theory. Any idea where i can get them? Books with mathematical expressions and equations are better... Thanks in advance..

FTL is possible! I think this proves a majority of Einstein's theories wrong! Read this article: http://www.newscientist.com/news/news.jsp?id=ns99992796 Encrypted

Somebody said that theory breaks down at the singularity of black holes, but I think at least Hawking has figured his way out of that (if I didn't suggest it first). It's not exactly rocket science. Somebody said that quantum theory doesn't match up in results to classic theory. What are the exact instances of that? You're not exactly comparing apples to apples. And if I remember right, most of the differences revolve around gravity. Will this new satellite put an end to all of the discrepancies and boundless speculation? Giving us a surefire theory of everything? I guess we would have to find the elusive but oh so necessary Higgs in order for it to be everything b…

First of all I hope this is a legitimate location to post this, as I've had enormous difficulty finding a forum that will even accept a new theory. :-S I'm proposing a new theory regarding spacetime and the preliminary underpinnings of some form of quantum-level relativity. A draft of my paper is located here: https://docs.google....JmOWYw&hl=en_US Its my first attempt at a scientific publication and the document still needs a little bit of work/tweaking, but its a start. The 3 real-valued dimensions of space are replaced with 3 complex-valued dimensions, allowing for a total of 6 spatial dimensions. The dimension of "time" is removed and the theory propos…

So I've heard somewhere or read somewhere on here that photons can distort the fabric of space, but what about energy itself? Why would energy need to take some other form to distort the fabric (mass) when it already does so? Because as you approach the speed of light, time slows down from your point of view, but the only time that time slows down in relativity is when the fabric of space get's distorted, which means by adding energy your somehow distorting the fabric of space more, but if energy doesn't carry "higg's bosons" or whatever causes mass, how does energy do it? I mean energy has relative mass, but it isn't mass itself, that's why it needs to be converted, so I…

When the Symmetry gets broken, how the Lagrangian gets affected in the Electroweak Force?

Hello everyone, I am trying to teach myself theoretical chemsitry and have done well so far. I am using this book called Modern Quantum Chemistry by Szabo. I was reading about Couloumb and Exchange opertaor and I have a question. I understand why Coloumb and exchange operator integrals arise, due to electrostatic potential and antisymmetry of the slater determinant. Then there was this exercise which made me pause. It asks to prove that the coulomb operator denoted by Jii and the exchange operator denoted by Kii are equal. Now in Chemists notation it the couloub integral Jab is given as Jij = (ii|jj) = <ij|ij> and Kab is defined as Kii = (ij|ji) = <ij|…

I was wondering, does SHM apply to anything that emits waves? and if so, does that mean light in its wave form have SHM? or is there something else to it?

4 dimensional geometry, cascading planes, and black holes first we must understand 4 dimensional geometry and math where one plus one is not always two. for instance, two humans given time and energy can produce a third individual human. two pieces of steel on the ocean floor can rust into a single piece. a circle has a begining and end in the form of puting a pencile down on the paper and lifting it on completion. within three dimensions you will see a density lap of the lead. During cognition of the event both ends are defined within the seemingly infinte plane of the paper. Is a red light really red? It depends on the color of lenz it is being viewed th…
