The Story of Inventors of Expanding Universe: From a Pastor & Physicist, Prof. Lemaitre to Observer with law's field background, Dr. E. Hubble (1927)
Georges Henri Joseph Édouard Prof. / Pastor. Lemaître is a catholic pastor and physicist in Belgium who was the first one introduced theoretically that our universe was actually expanded.
After calculating the theoretical physics of universe's expansion, he sent his work to Prof. A. Einstein for further discussion. Einstein was very impressed to his true theoretical work without any physical evident.
On the otherside, Dr. Edwin Hubble who was the astronomer with a background from law's field was in the initial process in observing universe and its galactics content as well as their behavior from earth with his telescope.
Based on Hubble data, it was detected that our universe has been expanded with a Hubble contant in 1927 of ~70 km/s/Mpc.
According to such inventor life, we can learn that "don't waste your life to work on useless works, but it is better to focus on your specific field of interest"
