Polarized starlight and the handedness of life.

The asymmetry of the amino acid ultimate particle s found in all living things may have originated in space billions of years ago We are all made of star dust. This assertion is in like manner well known that in a circles it has become a cliche. It imputes to the fact that just after the Big Bang (between 10 and 15 billion years ago-cosmologists are still not quite sure) the universe contained for the greatest part hydrogen and helium, with just traces of lithium and beryllium. All other chemical ultimate parts have since been forged either in the nuclear furnaces at the center of stars or in titanic supernova explosions.
