Unraveling the Big Bang Theory: Key Evidence and Discoveries from Astronomy

Dive into the groundbreaking Georges Lemaitre's proposal of the Big Bang Theory, with evidence like red-shifting and singularity's infinite density. Learn about Edwin Hubble's Hubble's Law, Arnos Penzias' discovery of cosmic radiation, and the age of the Universe at 6 billion years. Understand how galaxies' speed is linked to their distance, and explore the phenomenon of red-shift in light observation.

  1. Big Bang Theory Notes (Semester Final 2013)

  2. Georges Lemaitre proposed the Big Bang Theory~Evidence: Red-shifting~Singularity: a point of infinite density and temperature~Edwin Hubble: Came up with Hubble’s Law~Arnos Penzias discovered cosmic radiation~ Universe is 6 billion years old~Hubble’s law states that galaxies’ speed is proportional to their distance from earth~Red-shift occurs when light is moving AWAY from an observer
