Hertzsprung-Russell Diagram shows the life cycle of Stars – the process obeys and reveals laws of chemistry and physics
Newton found normal light has multiple wave lengths. Ballmer lines shows how an agitated atom give off a unique signature.
Spectral lines reveal what atoms emitted the light
Our large Mother Star formed in spiral arm of our galaxy and began manufacturing Atoms, small then larger atoms.
Our Mother Star blew up scattering Debreu Past events can be detected by reading light spectrum
All of our atoms were formed by the time our mother star blew up. It was not until 1850 that most atoms had been found. It was not until about 1980 that mathematics was worked out on how atoms are manufactured.
