Space Audio. Sounds from space. First Sound Waves Left Imprint on the Universe. SAN DIEGO -- The early universe rang with the sound of countless cosmic bells, which filled the primordial darkness with ripples like the surface of a pond pounded by stones. The wave fronts later served as spawning grounds for galaxies, astronomers announced Tuesday. The effect had been predicted by theory. Researchers found its imprint on the sky in two independent, comprehensive galaxy surveys presented here at a meeting of the American Astronomical Society. The findings give scientists greater confidence that their limited understand of the universe's structure, contents and evolution are on track. Sound waves in space may sound unlikely. The universe was initially a thick, hot soup that trapped light. Something similar should have happened with sound, explained Daniel Eisenstein of the University of Arizona and leader of one of the studies, based on the Sloan Digital Sky Survey.
In the dark era, if you pushed on a pocket of hot gas, it would resist being compressed and bounce back. Helioseismology.
