Carl Sagans Cosmic Connection - Assignment Example

Several elements were synthesized in the core of the stars that led to the Great Explosion (Big Bang). All basic atomic substances were created within the star by fusion and were spewed into space. In other words, the explosion propelled similar atoms and molecules to the entire universe.Scientists today believe that stars still emit numerous and huge quantities of the substances-the presence of which can be found everywhere in the universe. Obviously, these particles are also present in the human body.

For instance, according to Sagan, (2000, p.190), the components like the iron, calcium, and carbon in our body were produced billions of years ago in the interior of a red giant star. Therefore, the presence of the same atoms indicates our close association with the star. Sagan agrees that the universe involves an incessant process of explosion and propulsion. Heavy atoms like carbon, nitrogen, oxygen, and silicon, and the large quantities of organic compounds floating in the interstellar space would turn to be new planets or stars (Sagan, 2000, p.190).
