摘要：

Under the intense conditions of the early universe, ionized matter gave off radiation that was trapped within it like light in a dense fog. But as the universe expanded and cooled, electrons and protons came together to form neutral atoms, and matter lost its ability to ensnare light. Today, the protons from that great release of radiation form the cosmic microwave background (CMB). Thus, new observations of the cosmic microwave background radiation show that the early universe resounded with harmonious oscillations.
