THEORY OF THE  PHOTON AS A SELF-ACCELERATING PARTICLE                          A Reconsideration Of Newtons Double Prism Experiment        The observation of light accelerating should have been made and noted over a century ago.      A reconsideration of Newton's famous double prism experiment is offered here. During this experiment attention is paid to the different velocities of the speed of light as it makes its way through the procedure. In the classical observation light is refracted into the rainbow spectrum by the first prism and then recombined into white light by passing through the second prism. Interesting stuff but too distracting. In this observation it is noted that while light does slow down as it passes through both prisms, it returns to its original velocity, the speed of light, when exiting both the first and second prisms. The conclusion drawn from this is that light is a self-accelerating particle and can accelerate repeatedly, as Newtons experiment so clearly demonstrates.      To prove that the photons have returned to the speed of light can be verified by a Michelson- Morley Interferometer, an apparatus that measures the speed of light. This device will work for all electromagnetic radiation and can also be used to test whether other particles, sub-atomic or otherwise, have this same property of self-acceleration. A single beam of light is passed through a prism and directed into the interferometer, which measures the speed of the light that has just left the first prism.  From there the light enters the second prism and is directed into a second interferometer, which again measures the speed of light just after it leaves the second prism. Measurement of the velocities of light will reveal that although the light slows down due to the refractive index of the material it is travelling through, when it exits each prism the photons are found to be going the speed of light. This will prove beyond a doubt that the photons indeed return to the speed of light after having been slowed down. A second, more precise experiment can be devised later to determine if the acceleration is instantaneous or not.       The ability of light to accelerate requires a power source that is an integral part of the photon. In Physics it is generally accepted that the photon carries the electromotive force. Propagation of light is understood in terms of the changing electric and magnetic fields causing each other. However, the whole issue of being able to accelerate repeatedly seems to require a Power source. Stated here then, THE PHOTON ITSELF IS THE POWER SOURCE THAT ENABLES LIGHT TO SELF-ACCELERATE. Also noted, there is no explanation for this power source  in any theories dealing with the sub-atomic world, and none is offered here, either.       The acceleration of the photon is described by the following equation as expressed in words. The PHOTON ACCELERATION EQUALS WAVELENGTH TIMES FREQUENCY DIVIDED BY TIME. This is equivalant to speed of light per second, a constant. The standard physics equation for acceleration is distance divided by the square of time. In the event that the acceleration of light is found to be  instantaneous, the time dividend will include the two measurements needed, t2 minus t1, a time measurement based on wavelength length.       Self-acceleration of a photon is a particle property that is not listed in lists of particle properties. It should be. Consider that the acceleration of a photon may be the fastest possible acceleration allowed by the physical universe and, furthermore, it may also have an intrinsic natural value. On a list of the properties of particles, the photon is usually at the very top in a catagory by itself and listed as its own anti-particle. This is an already unique particle and the ability to self-accelerate only adds to its uniqueness. For this reason, the ability of light to accelerate should be listed as a photon property. That the photon itself is its own power source is another property of light that should be listed on a list of particle properties.       The role light plays in the cosmos is not fully appreciated. Matter would not, could not, exist without the binding participation of photons. Electrons and protons are bound together by very specific photon energies into neutrons, atoms, elements and compounds that form everything from stellar cores to terrestrial biology. Light of every wavelength fills the universe from the near beginning of time and across all of know space. Throughout the universe, photons are the cosmic lubrication.       To go over the double prism experiment again, each time light enters a prism it is slowed down by the refractive index of the prism. Then each time the light exits a prism it resumes its original velocity, the speed of light. By observing the different velocities of  light as it makes its way through Newtons double prism experiment, it is observed that even though light can be slowed down, photons will resume their original speed, the speed of light, once they exit the prism. Therefore, from considering this evidence the following theory is presented. The PHOTON IS A SELF-ACCELERATING PARTICLE AND CAN REPEATEDLY ACCELERATE TO THE SPEED OF LIGHT BECAUSE THE PHOTON IS ITSELF THE SOURCE OF ITS OWN POWER.    please send your comments to stevebtaylor44@yahoo.ca
