As I write this statement in the background section I will allow myself to answer the tagline of my film right away because it creates so much misunderstanding.
This is a "Spoiler" ;-) So if you have not seen the film and want to be surprised - Please STOP reading!
O.K. - IS IT POSSIBLE TO LIVE
ON LIGHT ALONE ?
If we use the definition of classical physics
, meaning light, as electromagnetic radiation, as a known part of the electromagnetic wave spectrum, we have to say definitely - NO. It is not possible to live on this light alone !
"IN THE BEGINNING THERE WAS LIGHT" however is working with a wider definition of "light", scientifically not well explored and in the mainstream violently rejected, meaning the "LIGHT OF LIFE", this universal vital energy called Qi in den Chinese tradition or Prana in India.
The traditional Chinese character for QI, the central principle of Chinese medicine, translated as universal "life force".
