Can you please tell me, what is ( PHOTON BELT ) ?

The Photon Belt is supposedly some phantom place our galaxy that our solar system is moving into or is already in depending on what you read. Apparently last time our solar system was in the Photon Belt "Atlantis disappeared".\nIt is supposed to be made up of some type of Photon Radiation that moves in and out of the light spectrum. There are reports that all sorts of weird stuff will happen as a result of us being in the Photon Belt. 5 days of darkness, UFO'S landing, being able to see 4th dimensional beings etc.\nDon't know if its true and don't have any proof that its not.\n\nMy belief is that its all crap. Your beliefs are up to you.

In quantum physics, the photon (from Greek φως, "phōs", meaning light) is the quantum of the electromagnetic field (light). That is to say, electromagnetic fields are made up of large numbers of photons, and the electromagnetic interaction is mediated by the exchange of virtual photons. The term photon was coined by Gilbert Lewis in 1926.\n\nThe photon is one of the elementary particles. Its interactions with electrons and atomic nuclei account for a great many of the features of matter, such as the existence and stability of atoms, molecules, and solids. These interactions are studied in quantum electrodynamics (QED), which is the oldest part of the Standard Model of particle physics.\n\nIn many circumstances, a photon acts as a classical particle, for instance when registered by the light-sensitive device in a camera. In other circumstances, a photon acts like a classical wave, as when passing through the optics in a camera. According to the so-called wave-particle duality of quantum physics, it is natural for the photon to display either aspect of its nature, according to the circumstances. Normally, light is formed from a large number of photons, with the intensity related to the number of them. At low intensity, it requires very sensitive instruments, used in astronomy or spectroscopy, for instance, to detect the individual photons.\n\nIn many cases, people may say a photon "sometimes acts like a wave and sometimes acts like a particle". This is slightly misleading, because a photon always acts like both. For example, when shooting single photons through a slit, a detector can detect each photon when it hits — but over time, the detector will detect the same diffraction pattern as it would if the photons were given off all in one burst. This is because any given trajectory the photon could take has a certain probability that is dictated by the properties of an electromagnetic wave.

Photon is pure energy .Thus it cannot be destructed .The last photon from a flashlight (also all the rest) gets converted to other forms like heat that gets transferred.

Radio waves, radar, lasers, visible light, infrared and ultraviolet light, microwaves, X-rays and gamma rays, all travel as mass-less tiny packets of energy (photons) at the speed of light.  They can all easily pass through a perfect vacuum (as could a bullet!).  In fact photons interact with the electrons orbiting atoms and molecules and can be absorbed kicking the electrons into higher more energetic orbits or entirely out of the atoms during ionization.  When electrons return to their normal (rest) orbits in one or more steps they give up their excess energy in the form of fresh photons.  When a substance absorbs the energy of photons it will heat up and when the photons are released again the substance will cool.  When you hold up your palm to the sun, you can feel the warmth of the billions of photons that strike your hand which will quickly cool in the shade as it gives up more (infrared) photons than it receives.\n\nThe light that reaches your eye from a distant star is merely composed of photons of different wavelengths (colors) that have traveled through the near-perfect vacuum of space perhaps for years at the speed of light without interacting with any electrons.  In fact, clouds of gas in space could prevent the light from reaching you.

Vacuum contains no particle (in classical sense) but lots of electromagnetic waves. photon (as a particle is a quantum mechanics concept) exists in vacuum. The problem with satellites around the sun is the heat radiation thats is emitted from the sun. Its difficult for instruments to work at that temperature. Things will melt though in vacuum.

I do not believe a photon can be enslaved at a perfect distance in orbit around a black hole.  The reason for this is because once the Photon has entered the event horizon at that perfect distance it would accelerate in its orbit from which it could never escape the gravataional pull of the singularity.  There is no opposite force, anti-gravity, to contain the photon in orbit around the event horizon.

Light travels through space as photons (tiny mass-less packets of energy).  Photons can interact only with the electrons surrounding an atom or molecule by kicking them to higher energy levels in higher orbits or shells.  If there is no matter with electrons (a perfect vacuum) the photons travel on unimpeded at the speed of light.  Space is almost a perfect vacuum and starlight (photons) can travel for thousands of light years without interacting with electrons to reach your eye.

A Van Der Graaf generator uses a belt to strip electrons from the base of the system and deposit them in the head(or dome) of the system. This creates a potential difference between the base and the head. The belt is made of an insulating material such as silk or leather. If you can find a few simple materials you can probably build one.

Swamp gas refracting the light off Venus?  Oh, wait, wait, wait, I got it!  Iran's nuclear program starting off with a bang!  No, no, that can't be it either.  I know!  A weather balloon from Roswell, New Mexico!  No?  How about the subject of SOHO's intense interest?  Yeah! That's gotta be it!  Whatever it is, I'm afraid to look directly at it!  Do I get the points?  Please?

The photon has energy. And energy can be converted into mass. Remember \n\nE^2=(m^2)( c^4) + (p^2) (c^2)\n\n----------\n\nI would agree with cedykeman1 that it does seem somewhat controversial to suggest that the photon is unstable. However, its energy can still probably be converted to matter, although the chance of getting those 3 exact particles seems a bit far-fetched (probably their antiparticles have to be produced as well, and various conservation laws followed carefully).\n\n--------\nI do not know what to say about goring, except to smile.

The focus in the 21st century for the forefront of physics is understand the connection between General Relativity and Quantum Mechanics. No question about this. The results could be a string theory, or loop gravity, or something completely different.\n\nAlso up there I think is a better understanding of a property we all know and love: mass. There is a search for the Higgs Boson. We need to find it and study it. Or, if it can't be observed try and determine what that means.\n\nOther challengs include being able to use the EPR phenomena of quantum entanglement to produce the first prototypes of an actual encrypted signal over a reasonable distance.\n\nNanotechnology is another challengs, in how to work those little parts into ways that form mini-computers, and also in ways that allow for various medical uses.

CIH is spot on, but you should also realise from what he said that electromagnetic waves or particles are ways of describing and calculating what a photon will do, they are not the actual photon itself (whatever that is). \n\nSometimes it easy to think that the description of an object IS the object, especially if it fits it well. If it was possible to write an equation or model which fully described a motor vehicle, you still wouldn't be able to drive it to the shops, but you would be able to accurately descibe how it drove there.\n\nIsn't physics wonderful! Philosopy and science all neatly wrapped up in one unifying theory of lots of theories!

This can be answered very, very simply.\n\nRelativity works well in  in it's area of expertise, astronomy and space science.  Basically, the scientists took the answers (how the planets revolve around the Sun, the Mass of the planets and stars, how the stars and galaxies move) and created an elegant series of equations to explain them all.  They believed their equations to be correct because this is what they were observing, so it must be true right?\n\nWell no, as we built better telescopes we began witnessing objects and entire galaxies moving far too fast for their observed mass, defying the equations and defying gravity!  It wasn't light pressure robbing these celestial objects of a few arc seconds, which is what sprung Einstein to whop up Relativity.  Venus was so much of a mystery, but Einstein cracked it, right?\n\nWRONG!  If the atom doesn't fit, you must aquit!  Electromagnetic forces have been known to cause these very same effects we witness the galaxies doing.  If the astronomers can't explain something they see, they blame it on magnetics.  Double-helix galaxies, just like our DNA, are floating around out there.  That should tell you where you should start looking to explain the molecular and Universal connection.\n\nVenus' orbit is nearly a perfect circle, and it spins the other direction very slowly.  It used to be called the hairy planet, the smoky planet, and bearded planet.  It's latin name means morning star.  It was literally glowing!  I'm sure some electromagnetic stuff was going on with it, and that would help explain it's brand spanking new surface.\n\nhttp://answers.yahoo.com/question/index;_ylt=AuzSsKSIJO_WapqWQB7tQcPsy6IX?qid=20060612222952AAFdmeo\n\nMars got blown the hell up.  That's a start on finding out about it right there, google should take you the rest of the way.  Hope this helped you understand why those two theories will never be united.  One of them, relativity, was based on a few wrong assumptions.

The astroid belt is a region between mars and jupiter that is densly populated with asteroids...scientists believe that this debris are the remains of a planet that existed once.
