The Big Bang Theory - Essay Example

Over 13 billion years ago, the universe we have emerged as a “singularity”. Despite the lack of proper definition, “singularities” are referred to as zones found within the center of yet another phenomenon, the “black holes”, which tend to violate the present laws of physics. According to scientific findings, the “singularities” or the core zones of the black holes had been subjected to high intensity of gravitational pressure that they can be thought of to consist of an infinite density. This consequently directed the universe to be understood in the light of the singularity concept in being infinitely hot and boundlessly dense while the universe at its initial state is also infinitesimally small. Nevertheless, the exact source of ‘singularity’ remains unknown beyond nearly accurate speculations.
Moreover, based on the Big Bang theory, the universe rapidly undergoes expansion since the beginning of time, and “the more distant the light source is, the greater the rate of expansion and ‘redshift’ is as well. This theory further claims that it is the universe that sustained itself the energy to expand and that it expanded from almost a mathematical point or microbial speck under a closely infinite value of initial temperature and material density.

The universe is proposed to have possessed an appearance that gradually inflated, expanded, and cooled, originating from a body of insignificant size yet of extremely hot conditions until these characteristics settle to the kind of universe conducive to our planet’s dwelling. The Big Bang theory holds that the formation of stars, galaxies, and black holes happened during the span of 500 million years when the universe was already in its expanded form, contrary to the conventional story of creation.
NASA’s Cosmic Background Explorer (COBE) satellite has been able to demonstrate the strongest most reliable evidence for the ‘big bang’ possibility. As such, the 3-Degree Kelvin Background Radiation, otherwise called the Cosmic Background Radiation (CBR) serves as the Big Bang theory’s model of validity, having exhibited the blackbody radiation with temperature slightly lower than 3°K which essentially peaks the microwave portion of the spectrum.

Through the Hubble Space device, galaxies are viewed to be moving farther from the center of the universe at speeds that are in direct proportion to their distance and this justifies the occurrence of rapid expansion. Similarly, the extraordinary hotness of the universe in the earliest times of its formation may be accounted for via the remnant of heat as conveyed in the use of Cosmic Microwave Background radiation (CMB). Additionally, the light elements such as ‘hydrogen’ and ‘helium’ which are abundant in the atmosphere, have specific features that reasonably provide logic to the roots of the Big Bang model.
