   Background radiation

   Background radiation is constantly present in the environment and is emitted from a variety of natural and artificial sources. ... A particular example of this is the cosmic microwave background radiation, a nearly uniform glow that fills the sky in the microwave part of the spectrum; stars, galaxies and other objects of interest in radio astronomy stand out against this background.

   Steady State theory

   In cosmology, the Steady State theory (also known as the Infinite Universe theory or continuous creation) is a model developed in 1948 by Fred Hoyle, Thomas Gold, Hermann Bondi and others as an alternative to the Big Bang theory (known, usually, as the standard cosmological model). ... For most cosmologists, the refutation of the steady-state theory came with the discovery of the cosmic microwave background radiation in 1965, which was predicted by the Big Bang theory.

    Birth cries of atoms

    Robert Millikan (1868–1953) pursued the theory of birth cries of atoms for many years, to explain the origin of cosmic rays. ... The cosmic microwave background radiation was recognized after its discovery in the 1960s to be the remnant of the decoupling of atoms from photons which freely streamed after the surface of last scattering.
