BIG BANG- the theory that the universe was once a small singularity but then began a sudden expansion.
Name: Albert Einstein Reasons to date: independent- In 1917 I refused to believe the universe was expanding and instead believed my own theory of a static, universe.
Name: Georges Lemaitre Reason to date: smart- in 1927 I discovered a solution to Einstein's field equation of relativity and wrote the report 'A homogeneous universe' which describes not a static universe but an expanding one
Name: Edwin Hubble Reason to date: dedicated- in 1929 I announced galaxies appear to be moving away from us, the universe is expanding and therefore the galaxies are moving away from eachother. This phenomenon was noted as redshift and supported Lemaitre.
Name: Fred Hoyle Reason to date: not always right- I proposed the steady state theory in 1948 (new matter and new galaxies are continuously created to maintain the perfect cosmological principal thus creating the expansion of the universe but was thrown out the window when CMB was discovered
Name: Brian Schmidt Reason to date: I'm Amazing- I justified the accelerating expansion of the universe through the observation of a type of la supernovae. this was in 1998 with my team and prior discoveries such as redshift we were able to gauge how fast the universe is expanding
