George Lemaitre And The Big Bang Theory

Decent Essays
Good morning/afternoon Ms Jungmann and class.
Now we all know that before life has begun, there was nothing. But the big bang theory is a scientific way to explain what happened at the very beginning of our universe.
George Lemaitre is the priest and physicist who was born in 1894 in Charleroi, Belgium that perhaps made the greatest discovery in modern cosmology, the discovery that our universe is expanding. In his early age, he was attracted to both theology and science but was soon interrupted by World war 1. However, after the war, he soon studied theoretical physics and in 1923 he was ordained as an abbe. Lemaitre then pursued his scientific studies and studied astronomy at Cambridge University and returned to Belgium to become a

George called this the ‘primeval atom ' but we know it as the ‘Big Bang ' (Edel Fletcher, 2017).
5. Moving on to 1948, the year where an alternate theory is presented by Fred Hoyle, who questioned the ‘primeval atom ' theory (Edel Fletcher, 2017).
6. The 1950s, the time where doubts and a new perspective was born as the scientific community divided. Big bang versus Steady state (Edel Fletcher, 2017).
7. However, in the 1980s is when the Big Bang Theory gained its popularity from its clear observations, data, and evidence (Edel Fletcher, 2017).
8. But in 1965, the Cosmic Microwave Background was discovered when the Bell Labs ' Holmdale Horn Antenna in New Jersey picked up a buzzing sound which came in different directions in the sky. Its pretty much an electromagnetic radiation left over from an early stage of the universe in the Big Bang cosmology (Edel Fletcher, 2017).
9. Then in 1980, a fellow professor called Alan Guth who proposed the idea of inflation, a process where the universe extremely undergo a rapid expansion after the event of the big bang (Edel Fletcher, 2017).
10. 1989, the time when the Cosmic Microwave Background Explorer Satellite was launched (Edel Fletcher, 2017).
11. Lastly, the future, 2020. The predictable year of when the future cosmologist would be developing an even deeper understanding of how everything
