Monsignor Georges Lemai®tre was a Belgian Roman Catholic priest, physicist and astronomer. He is credited with the first precise formulation of the idea of an expanding universe and what was to become known as the Big Bang theory of the origin of the universe, which Lemai®tre had called his "hypothesis of the primeval atom." Lemai®tre went to school at Harvard College in Massachusetts, U.S.A.

In 1921, Einstein won the Nobel Prize for physics for the photoelectric effect. His work had an impact on the development of atomic energy. Later, Einstein focused on field theory. Einstein is typically considered the most influential physicist of the 20th century. As a physicist, Einstein had many discoveries, but he is perhaps best known for his theory of relativity and the equation E=MC squared (energy equals mass times the speed of light squared), which then helped the development of atomic power and the making of the atomic bomb. He was one of the first people to thing of the theory for the Big Bang.

"Alexander Friedmann was a Russian cosmologist and mathematician, who helped develop models that explained the development of the universe. In particular, his solutions to Einstein’s field equations provided early evidence of an expanding universe, and the theoretical underpinnings for both the Big Bang and steady state models of the universe. Our universe can be described mathematically by a simple model developed in 1922 at Petrograd (St. Petersburg) by Alexander Friedmann (1888-1925). Without the benefit of observational evidence, Friedmann predicted that the whole universe would expand and evolve with time. This astonishing prediction was confirmed seven years later by Edwin Hubble. Its originator, unfortunately didn't live to savor this triumph. He also did work on theoretical cosmology (1922-1924)."

Some people are still weary about this theory. The leading interpretation about the universe’s birth solved many puzzles and fits all observations. This "cosmic inflation" theory lacks actual proof. The absence of the "ripples" has fueled some weaker theories of cosmogenesis in recent years.

The question is whether anyone can test the scenario for the inflation. Avi Loeb, an astrophysicist and cosmologist at Harvard University, had similar thoughts over this. He also thought that if there is no other evidence that can kill off some theories, then what was the point? The Big Bang basically only has one theory, but there is a couple more. When people hear a big bang, they think of an explosion. But that’s probably not what happened. A lot of thoughts are on a fast inflammation. Before the Big Bang happened, no one knows. After the "bang" went off, the cosmos goes through a super fast "inflation" expanding from the size of an atom to a grapefruit in a tiny fraction of a second. After that happens, the universe starts to have electrons, quarks, and other particles that happen in a couple seconds. Then, a fast cooling macrocosmos permits quarks to clump into protons and neutrons that happened in about a minute. Electrons combine with protons and neutrons to form atoms, mostly hydrogen and helium after. Light can finally shine. This step took about 350 years. Subsequently, gravity pushes hydrogen and helium together to form giant clouds that made the galaxies we know today. Smaller clumps of the gas came together to form stars. Lastly, old stars died out to give out elements into space, which form new stars and planets.

Another theory is God. Genesis 1:1 at the start of the bible, says "in the beginning God created the Heaven and the Earth." Christians believe this is how the universe started. They might not be wrong but scientifically, this is impossible. The Greeks and Romans worship Gods that created the Earth. According to legend, Gaia and Ouranos made the Heavens and the Earth. There’s no actual proof of this either so it can’t really be proven right. Even though all religions all worship some god(s), scientists can’t be blinded by this. They have to think scientifically. Albert Einstein, Monsignor Georges Lemai®tre, and Alexander Friedmann were all great scientists. Their contributions to science give us a better understanding.
