EVIDENCE FOR THE BIG BANG:
THE SHIFT TO RED IN THE
LIGHTS OF GALAXIES
The spectra of an
approaching star

tend towards violet
The spectra of an
distancing star tend

towards red
An observer who views the spectra of a distancing object will see that this
become increasingly redder. Observations made from the earth have shown that
the spectra of light beams of the galaxies and stars in the sky increasingly tend
towards red. This means that heavenly bodies constantly move away from us.
The discovery of this fact by observations made in the 1920's has proved that the
universe has an expanding structure and that it originated in the Big Bang.
