Something from Nothing: The Big Bang Even though the equal balance of matter and antimatter created in the beginning of the universe as proposed by the Big Bang theory might have annihilated each other before any stars could form, the inflation model of the Big Bang accounts for the unequal level of matter-antimatter existing today and how stars could form before matter-antimatter reactions destroyed the universe. The existence of the Cosmic Microwave Background Radiation (CMBR). is in line with what is predicted by the Big Bang Theory, specifically that the CMBR exists. The expansion of the universe outward also supports the Big Bang theory as the expansion of the universe, just like the expansion of an explosion, reveals that there was …show more content…
It provides another piece of direct evidence, in case any is needed, that the Big Bang really happened, because it allows us to look back directly and detect the nature of the very young, hot universe from which all the structures we see today later emerged” (Krauss 42). The Cosmic Microwave Background Radiation fills the Universe as electromagnetic radiation, this radiation can only be detected by a radio telescope. The Cosmic Microwave Background Radiation shows up on a radio telescope as a faint glow. The glow of the Cosmic Microwave Background Radiation is the strongest microwave wave on the radio spectrum (Coffey). In 1964 radio astronomer Robert Wilson, along with physicist, Arno Penzias discovered what is now known as the CMB or Cosmic Microwave Background. The CMB is the remnant heat left behind by the Big Bang, the CMB contains tiny temperature variations but is remarkably uniform. Something that might be expected if the universe expanded from a very small region (Lewis). The CMBR is the most accurate and precisely measured black body spectrum in nature, the CMBR was measured by the Far-Infrared Absolute Spectrophotometer. The results from the Far-Infrared Absolute Spectrophotometer showed that the CMBR is isotropic to roughly one part in 100,000 (Coffey). WMAP, The Wilkinson Microwave Anisotropy Probe, measures properties of the CMBR and in doing this reveals early universe conditions (Griswold).
