A growing body of evidence suggests that the molecular machinery of life emits and absorb photons. Now we have evidence that this light is a new form of cellular communication. Biophotons, or ultraweak photon emissions of biological systems, are weak electromagnetic waves in the optical range of the spectrum - in other words: light. All living cells of plants, animals and human beings emit biophotons which cannot be seen by the naked eye but can be measured by special equipment
This light emission is an expression of the functional state of the living organism and its measurement therefore can be used to assess this state. Cancer cells and healthy cells of the same type, for instance, can be discriminated by typical differences in biophoton emission.
Talk about the universe made of high energy photons (light), then the fundamental force in nature acting as a glue for matter is Electromagnetic Force (Light), our food being produced in plants by light, then neuron activity and electromagnetism and now light emanating from our bodies. Even though, light fills up our Universe but around all of this matter is the number one Immaterial entity. Photons are massless particles (Not matter) that have a dual nature of behaving both as wave and particles. Now we can better appreciate the supplication of the Prophet (pbuh) for "light" in his body, in his skin, bones,hair, muscles before every prayer-light being synonymous with physical and spiritual well being.
