The Origin of Chiral Life
  The phenomenon of life is discussed within a framework of its origin as
defined by four hypotheses. The 1. hypothesis says: Life, as we know, is
(H-C-N-O) based and relies on the number of bulk (Na-Mg-P-S-Cl-K-Ca) and trace
elements (Cr-Mn-Fe-Co-Ni-Cu-Zn-Se-Mo-I-W, and possibly Li-B-F-Si-V-As). It
originated when the element abundance curve of the living matter and of the
Universe, coincided. The 2. hypothesis is: Life originated in an interstellar
molecular cloud with the critical role of dust particles. The 3. hypothesis
arises from the 1. and states: Because of the Universe ageing, life originated
only once. The dust forming planetary system and stars already contained an
excess of L-type amino acids and D-type sugars, therefore, the emerging life on
any planet had to be chiral. Consequently, the 4. hypothesis has been formed:
Chirality is a sine qua non-condition for the emergence of life. The arguments
supporting these hypotheses are put forward based on numerous astrophysical
observations and physics laws.
