Long before science, light was considered primal. In Egypt, light from the Sun god Aten sustained all, and in the bible, God created light before the sun, moon, stars, or man. Light is all around us today but what it is remains a mystery. As Einstein wrote just before he died:
“All these fifty years of conscious brooding have brought me no nearer to the answer to the question ‘What are light quanta?’ Nowadays every Tom, Dick and Harry thinks he knows it, but he is mistaken.” (Walker, 2000), p89.
Even today, science still can’t answer the question what is light?
