Abstract
A theoretical study of the gas dynamics and chemistry of lightning-produced shock waves in a postulated primordial reducing atmosphere was conducted. It was shown that the conditions are similar to those encountered in a previously performed shock-tube experiment which resulted in 36% of the ammonia in the original mixture being converted into amino acids. The calculations gave the (very large) energy rate of about 0.4 cal/cm2/yr available for amino produproduction, supporting previous hypotheses that ‘thunder’ could have been responsible for efficient large scale production of organic molecules serving as precursors of life.
