WASHINGTON (CNS) -- The work of researchers who reported detecting the signal left behind by the rapid expansion of space billions of years ago is rooted in the efforts of a Belgian priest whose mathematical computations in the 1920s laid the groundwork for the Big Bang theory. Msgr. George Lemaitre, a mathematician who studied alongside leading scientists of the first half of the 20th century exploring the origins of the universe, suggested that the cosmos began as a super-dense "primeval atom" that underwent some type of reaction that initiated the expansion of the universe which continues today. The priest's conclusions challenged the conventional hypothesis proposed by luminaries such as Albert Einstein and Fred Hoyle that the universe was in a steady state. Researchers in cosmology over the decades refined Msgr. Lemaitre's idea, leading to what became widely known as the Big Bang theory and later ideas that signs of the Big Bang can be detected. The most recent evidence supporting the Big Bang emerged March 17 when a team of scientists announced they detected polarization in light caused by primordial gravitational waves originating from the Big Bang. The measurements were made with the Background Imaging of Cosmic Extragalactic Polarization experiment, or Biceps2, located at near the South Pole.
