Actually both of you are incorrect. Mass and energy are equivalent, they are not interchangable. A photon particle has an equivalent mass, but it still doesn't have mass, so you can't say they are interchangable as that implies they are the same, they are not. When a photon of ENERGY is released it is a wave traveling at c ( note: c is not capitalized for speed of light ). If that photon is converted to mass, some or all of its kinetic energy is converted to mass. At that point since it has lost kinetic energy, it also loses speed and the now particle of mass can no longer reach c. Unless it is converted back to energy. An example of this is a gamma ray passed near an atom disappears and a positron and electron are produced. The gamma ray energy at c which has no mass is converted to mass of atomic particles traveling at sub light speeds. If you check my original post it gives the formula for mass of a moving object. It is m = m0/(1-(v^2/c^2))1/2 , m0 is rest mass. Since a photon has no rest mass ( it cannot exist at rest ) you have mass at c = 0 / 0, which is still zero, no mass. Since…them little photons can't do it…I dought we can 🙂 // .An Ameoba on AutoPilot 🙂 \X/
