  • Einstein's theory of relativity

    Einstein's theory of relativity
    Albert Einstein developed his theory of relativity. This suggested that the universe was not standing still and it was either expanding or contracting
  • Hooker Telescope

    Hooker Telescope
    Hubble used this telescope to observe the expanding universe. He refined the universe's distance scale. It was the largest telescope in the world when built.
  • Alexander Friedman

    Alexander Friedman
    He discovered the expanding-universe solution to the general relativity fielkd equations. His cosmological model of relativity became the standard for the Big Bang Theory.
  • Georges Lemaitre

    Georges Lemaitre
    He determined the universe was expanding due to the red shift surrounding the galaxies. He published his calculations but few people took notice. Also stated the univese began at one point.
  • Hubble's discoveries

    Hubble's discoveries
    Edwin Hubble determined the universe is expanding. This suggests the universe started from a compacted point
  • George Gamow expands on Lemaitre's discoveries

    George Gamow expands on Lemaitre's discoveries
    Determined the universe began with a fireball whos warmth continues to fill the universe. Also belived starting nucleus was filled with protons, electrons, and neutrons which by nuclear fusion combined to form elements. Also predicted CMB radiation.
  • Fred Hoyle names the theory

    Fred Hoyle names the theory
    Hoylr rejected the big bang theory and on BBC radio's Third Programme broadcast at 1830 GMT in an attempt to put it down he referred to it as a "Big Bang" which was interpreted by the public as a positive phrase. He later coined the phrase and it suck.
  • Cosmic Background Ratiadtion

    Cosmic Background Ratiadtion
    Arno Penzias and Robert Wilson, while conductiong diagnostic observations, discovered the cosmic background radiation using a new microwave receiver from Bell Laboratories. It confimred the CMB predictions. The radiation was isotropic and consistent with a blackbody spectrum of around 3 K
  • COBE

    It was launched to observe and study the infared and microwave radiation from early universe surrounding the universes. This is called cosmic background radiation. This radiation is believed to be left over from the Big Bang.
  • Hubble Space Telescope

    Hubble Space Telescope
    One of the largest and most versatile space telescopes and is essential to space research. Helped determine the Hubble constant which is the rate at which the universe is expanding.
