    • When looking at Betelgeuse, which is approximately 642.5 light-years away, approximately 5.64 million photons per second would enter the human eyekalkal

    • Chemical reactions within your body, besides liberating energy and producing heat, are also emitting small numbers of photons, elementary particles of light. :)robthelad
