According to Carl Segan Why We Are Star Stuff – Assignment Example

The paper "According to Carl Segan Why We Are Star Stuff" is a wonderful example of an assignment on social science. Carl Sagan (1934-1996) the scientist must be the first individual who challenged traditional concepts of the origin of the universe. According to his conviction (1980), the whole objects of the universe including human body are made out of the remnants of a big star. He reaches this conclusion relying on the finding that every element in the universe holds the atoms and molecules of similar features. To illustrate, according to Sagan (2000, p.190), our Sun is only a third generation star which might have incorporated the atoms of the so-called big star. He calls the phenomenon of the great star explosion as ‘Big Bang’ which happened as the star went supernova and spewed numerous atomic components into the immeasurable surrounding space. Furthermore, the subsequent explosions continue in the universe and stars are still blowing off large quantities of organic and metallic compounds into space. These various elements not only form new planets and stars but also have incorporated into every living and a non-living thing of the cosmos. For instance, the essential elements of the human body such as the iron in our blood, the calcium in our teeth were once created in the core of the star just by fusion and were expelled to the outer space (Sagan, 2000, p.190). As Sagan rightly puts it, “we humans have seen the atoms which constitute all of nature and the forces that sculpted this work and others” (Sagan,). He further states that we indeed have a close association with stars, perhaps that has a long history of millions of years. That is the reason why we can be called ‘star stuff’. Although his theory lacks proven facts and evidence, Sagan indeed intensified the concept of extraterrestrial life among modern scientists.
