Fritz-Albert Popp is a German biophysicist who confirmed the existence of biophotons, particles of light that transmit information between and within cells. He found that the light that cells emit, unlike most light, is highly ordered. It also changes with biologic rhythms, and provides the information necessary to control the hundreds of thousands of reactions occurring in every single cell, every single second. When studying food, he found that the biophotons in eggs from free-range hens were more coherent that those from caged hens. He discovered that DNA emits light to induce and control reactions and that the light in cancerous cells has lost all coherence. Popp was a visionary and his work laid the foundation for the understanding that we are truly beings created and controlled by light.
