Study of Big Bang Theory and Cosmos

d.). At some point, however, the populace began expanding rapidly (Shipper, n.d.). Some scientists conceive this expansion as offset with a "big bang," or explosion, that somehow brought together molecules that produced life. tail end Gribbin (1999, p. 77) describes the Big Bang as "the outburst in which the world was born." When Penzias and Wilson in 1964 conducted an experiment to improve microwave communication, they made an unanticipated finding; they "detected the background radiation of the universe, a finding that strongly supported the 'Big Bang' theory" (Conrad & Serlin, 2006, p. 14).

A galaxy state to come resulted from the Big Bang is the whitish focal point. The Milky Way is an odd-shaped galaxy that looks like a spiral, composed of more than four hundred billion stars and gas and dust that form three main components(the resplendency, the nuclear bulge and Galactic Center, and the disk (Smith, 1999). The halo is a round entity that contains the oldest k outrightn stars; these include 146 "Globular Clusters" that scientists believe were form when the galaxy was just forming (Smith, 1999). They atomic number 18 aged 10 to 15 billion years old according to their Hertzsprung-Russell diagrams (Smith, 1999). The halo is characterized by "a very diffuse, hot, highly-ionized gas" that produces "a gamma-ray halo," although the exact specifications of the halo such as its full extent and mass are not known (Smith, 1999). St

The nuclear bulge is the core of the galaxy and has the densest component of stars in the Milky Way ("Components of the Galaxy," n.d.). Like the halo, it is comprised mainly of old stars but as well as has some hotter young stars ("Components of the Galaxy," n.

d.). The core is difficult to see because of the dust, gas, and stars that unnamed it at visible wavelengths, but it can be notice at other wavelengths ("Components of the Galaxy," n.d.).

udies of the halos in other galaxies having the same spiral structure have piece that the halo gas extends removedther than scientists originally imagined(as far as hundreds of thousands of light years (Smith, 1999). When scientists studied the Milky Way's rotation, they found that "the halo dominates the mass of the galaxy, but the material is not visible, now called dark matter" (Smith, 1999).
