Sound Waves from the Universe

Caption: NASA's Wilkinson Microwave Anisotropy Probe collected data that produced this chart of sound waves from the universe. Called a power spectrum, the chart plots the cosmic microwave background radiation as ripples of different sizes across the sky. The data are consistent with predictions of cosmic inflation theory.
