There is little doubt that the universe started as light. It happens to have emerged as one of the most potent properties of life. In a sense, we are light! That’s not a New Age claim; that’s scientific fact. Biophotons are here to stay.
Light is just part of the electromagnetic spectrum and we in turn are composed of electromagnetic energies. Energy, heat and light all come from this spectrum; today, every schoolkid knows that matter and energy are interchangeable. Voila! Light is life.
It has always been curious to me that the whole of the electromagnetic spectrum is hostile to biological life… except light and heat (and even heat can be damaging to life).
But not light!
