MY ELECTRO – MAGNETIC THEORY, IN 1867, PREDICTED THE EXISTENCE OF ALL THESE WAVES.

1963: Quasars

Careful observations by radio and optical astronomers in the years 1960 to 1962 showed that there were over a half-dozen bright objects in the sky which were small enough to be stars but had a weird light spectrum – not like any star seen before.

Everyone was puzzled until 5 February 1963 when astronomers Maartin Schmidt and Jesse Greenstein at Caltech made a discovery.

WE REALIZED THAT THE HYDROGEN SPECTRAL LINES IN THE LIGHT FROM THESE OBJECTS (AN EASY-TO-RECOGNIZE SIGNATURE IN THE SPECTRUM OF A STAR)… …HAD BEEN SHIFTED BY A VERY LARGE PERCENTAGE TOWARDS THE RED (LONGER) WAVELENGTH.
