Mystery of Mass/Mass asymmetry/Fifth Force/Cosmic Cycle

Abstract

All molecules in nature come in two mirror-image versions, “righthanded” and “left-handed.” Natural chemical reactions produce approximately equal numbers of both types. But DNA, the building block of ‘life’ on earth, has only right handedness. Cosmic rays may have tipped the balance in favour of Right handedness in the evolution of ‘life’. Right & left-handedness are observed in
polarised light.
