I have been reading a book entitled "The Field" by Lynne McTaggert, a book that could revolutionize our view of the universe once again. One of the key notions in this book is the discovery of biophotons, a new study in the field of biophysics that could have a far-reaching impact on our ideas of life and consciousness in the universe. What are biophotons and how were they discovered? "Biophotons, or ultra weak photon emissions of biological systems, are weak electromagnetic waves in the optical range of the spectrum - in other words: light. All living cells of plants, animals and human beings emit biophotons which cannot be seen by the naked eye but can be measured by special equipment developed by German researchers. This light emission is an expression of the functional state of the living organism and its measurement therefore can be used to assess this state. Cancer cells and healthy cells of the same type, for instance, can be discriminated by typical differences in biophoton emission.
