ABSTRACT: The coherence of the interaction of light with a collisionless gas
(Einstein 1917) founds the theory of gas lasers. It is, for the understanding
of universe, a simpler and more powerful tool than the big bang which requires
questionable supplements (dark matter, MOND, etc.). The Impulsive Stimulated
Raman Scattering (ISRS) redshifts gradually light pulses which cross excited
atomic hydrogen H*, so that the redshift is a measure of the column density of
H*. Thus, the distance of the hot stars, surrounded by much H*, is exaggerated
by the use of Hubble’s law. Local exaggerated distances create voids in the
maps of galaxies which become spongy. The interpretation of spectra of quasars,
the periodicity of galaxy redshifts introduce an experimental “Karlsson’s
constant” exactly computed by ISRS. The need for dark matter comes from the
exaggeration of the distance, therefore the size of galaxies. Without dark
matter, celestial mechanics provides a reliable distance of spiral galaxies.
Coherence also introduces superradiance and mode competition that explain that
only the limbs of Stromgren spheres are visible as circles maybe punctuated by
an even number of dots: Too numerous, the figures assigned to gravitational
lenses can be such limbs. The coincidence of the ignition of the rings of SNR1987A
with the extinction of the star is due to a multiphoton coherent scattering of
star light, which amplifies the superradiant emission of the rings. A blueshift
of microwaves crossing H* resulting, between 10 and 15 AU, of the expansion of
solar wind, explains the “anomalous acceleration” of Pioneer probes. All is
obtained without any change in theories of standard spectroscopy.
