A significant discovery can be credited to Edwin Hubble. The Big Bang theory represents cosmologists' best attempts to reconstruct the 14 billion year story of the universe based on the sliver of existence visible today. A more specific theory called "Big Bounce" proposes that the universe could collapse to the state where it began and then initiate another Big Bang, so in this way the universe would last forever, but would pass through phases of expansion (Big Bang) and contraction (Big Crunch). Georges Henri Lemaitre, a Belgian catholic priest and an astronomer was the first one to develop the Big Bang Theory in the year 1920. Cosmologists have predicted that stars didn't form for another 180 million years. THE Big Bang theory has been thrown into question after scientists discovered a star which appears to be older than the Universe itself – and it could lead to a “scientific crisis”. The universe began with a bang. The Big Bang theory is an effort to explain what happened at the very beginning of our universe. Big Bang theory: Scientists discover what happened BEFORE the Big Bang THE Big Bang theory has long been accepted as scientific fact as an explanation of the universe came into being – … Though Alexander Friedman, a Russian Cosmologist was the first to derive the solution of the expanding universe to the … The "Big Bang Theory" is going through that process right now. Lemaître is also credited with proposing what has now become known as the Big Bang theory – which says that the observable. Physics and the Big Bang Theory have also changed dramatically since then. The Big Bang theory represents cosmologists' best attempts to reconstruct the 14 billion year story of the universe based on the sliver of existence visible today.. Recently discovered by a team of international scientists, it … Discoveries in astronomy and physics have shown beyond a reasonable doubt that our universe did in fact have a beginning. On this day 120 years ago, Georges Lemaître, ‘father’ of the Big Bang was born in Belgium. hi. He thought that the primeval atom had always existed, but we now can show that the Big Bang created the matter as it expanded. Quantum mechanics shows that "nothing," as a philosophical concept, does not exist. He made the observation that the distances between galaxies was expanding, a fact that could be explained equally well EITHER by Steady State Hypothesis or by a Big Bang.
