The Origins of First Stars - Essay ExampleInvestigating how from the universe was created and how this led to the precise spot in time when these set-back stars could and did evolve was researched and presented. Through a thorough examination of years of research, how first stars were created and when they came into existence was answered. This research also yielded the fact that no first star still exists within our galaxy - the Milky Way. Although, I am satisfied with the findings of this research that the Milky Way contains no Population troika Stars, I can non help but sit here and wonder if somewhere in the outermost areas of the universe, in areas we may not even up know exist, there sits a first star, a remnant of the very creation of the universe, waiting for meEver since the dawn of time, man has been fascinated by the stars in the heaven. From a childs first wonder at the twinkling lights in the night sky to throngs of people staying up late to watch a meteor shower, t he aerial display never ceases to amaze us. However, there is so much more to stars than the glowing light they project to earth. They are the footprints to understanding the origins of space and time. Scientists have been in the process of unraveling these mysteries for centuries. ... The Big Bang Theory, the accepted theory of the creation of the universe, which will be detailed in subsequent paragraphs, lead to the later creation of first stars, called Population III Stars. Initially thought impossible to still exist, these first stars and the quest to understand them have led researchers to continue to search for their origins. The first detectable signs of these Population III stars have now been found. How were they created and do any still exist BackgroundUnderstanding what is known about the creation of the universe is prerequisite consider how Population III stars were born and if they have survived to present day. The accepted theory of the creation of universe is the B ig Bang Theory. Astronomers have determined done observation and scientific research that the galaxies of the universe all seem to be moving away from us. It turned out that they are moving away not just from us but from one another-that is, the universe seems to be expanding. 1 The laws of physics, specifically Hubbles Law told scientists that if the universe is ever expanding. Hubbles Law explains that the galaxies were receding from us at a fastness proportional to their distance. The more distant the galaxy, the greater its redshift, and therefore the higher the velocity. 2Hubbles LawThe above graph is a depiction of the Hubble constant explaining rate of expansion. 3The velocity v could be determined by multiplying the distance R by H, the Hubble constant, given by the slope of the line in the above graph, in units of kilometers per southward per million light years. The Hubble constant describes the universes rate of expansion. The galaxies are not moving away through space , they are moving away with space, as space
