A Brief Theory: The Big Bang Theory

2405 Words10 Pages
The Big Bang Theory Introduction Scientists mainly Physicists believe that our universe’s existence is built upon the blocks of the cosmic cataclysm unmatched in all of history—the big bang. This theory was born because of the dispersion of galaxies from our own Milky Way galaxy at a great speed in all directions suggesting that the galaxies had be propelled by an ancient explosive force. Scientists believe that before the big bang, the entire vast universe including all of its matter radiation was compressed into a hot, dense mass just a few millimetres across. This nearly incomprehensible state is a hypothesis and is believed to have existed for just a fraction of the first second of time; this might be known as the factor of singularity…show more content…
In the 1920s a Belgian priest by the name, Georges Lemaitre was the first person to propound the big bang when he theorized the concept of the singularity of the universe, in other words a single primordial atom. His work received significant boosts from Edwin Hubble’s observations of how the galaxies where moving away from a central point of origin and from the discovery of cosmic microwave radiation by Arno Penzias and Robert Wilson. The big bang leave several unanswered questions, like what was the original cause of the big bang itself, though several suggestions have been proposed to address the fundamental question but have succeeded in providing a worthy answer. The big bang theory claims that after the occurrence of the bang, the universe started expanding at an incomprehensible speed from its size origin to the astronomical scope. Since then expansion has continued to take place but more slowly over the billions of the years. So ever since the bang our Milky Way galaxy has started to evolve on its own to the world that it is…show more content…
The emptiness is supposed to have gathered together in one place, and gotten so thick that the "nothing" exploded and blew itself into hydrogen gas Evidence for the big bang theory • First of all, we are reasonably certain that the universe had a beginning. • Secondly, there is what is known as "Hubble's Law," named after Edwin Hubble (1889-1953) who discovered a phenomenon in 1929 which states that, galaxies appear to be moving away from our Milky Way galaxy at speeds proportional to their distance. This result supports the expansion of the universe and suggests that the universe was once a single unit. • Thirdly, if the universe was initially very, very hot as the Big Bang suggests, we should be able to find some remnant of this heat. In 1965, Radio astronomers Arno Penzias and Robert Wilson discovered a 2.725 degree Kelvin, Cosmic Microwave Background radiation (CMB) which pervades the observable universe. This is thought to be the remnant which scientists were looking for. Penzias and Wilson shared in the 1978 Nobel Prize for Physics for their discovery. • Finally, the abundance of the "light elements" Hydrogen and Helium found in the observable universe are thought to support the Big Bang model of
