The Big Bang Theory - Essay Example

The big bang model had its beginning back in 1929 when Edwin Hubble observed that galaxies were receding away from each other (Lukowich, E, (2014). It starts in a singularity. In between thirteen to seventeen billion years ago, an unknown event occurred that initiated expansion from the singularity. The expanding universes then near instantaneously inflated by an astronomical amount iron out and prevent recollapse. The resulting fireball produced an expanding cloud of mostly hydrogen gas. The gas condensed into stars and galaxies nevertheless many generations of stars came and went, each exploding to produce the elements heavier than helium that was recycled into succeeding generations of stars.

The sun formed after by gravitational collapse of a gas and dust cloud the leftover gas and dust accreted by some unknown methods into larger planetesimals. The larger growth of these planetesimals, the impacts melted them, and eventually, they grew large enough to form planets. Consequently, the earth cooled, the surface hardened, water appeared from somewhere life formed. There are other theories in contrast to the big bang. As per the theory of the steady-state that posits nonstop creation of matter all over the universe to explain its apparent enlargement in that the universe will be infinite without a beginning nor end.

In addition, the Eternal inflation model also posits that inflation has not stopped and has continued to go on for an inestimable length of period. Galaxies seem to move away from the earth at speeds relative to their distance, this observation backs up the development of the universe as well as suggests that the universe in a time it was compacted. Suggestions from Big Bang that the universe was hotter, researchers are capable of finding some remnant of this heat. Proofs by scientists Penzias and Wilson support this through studies in Cosmic Microwave Background radioactivity which infuses the observable cosmos.

Finally, plenty of the light components that are hydrogen as well as helium set up in the observable cosmos are supportive of this theory. Hubble’s observation in that galaxies display a redshift expanse relationship, this relationship likewise provides the age of the universe (Parker, B. R, 2013). Big bang theory doesn’t explain fully how spheres of the universe formed or rather how solar systems or galaxies came to being. It also absolutely doesn’t explain the complexities of the universe right from the micro-world of small atoms, to the macro world solar systems and galaxies (Lukowich, E, (2014).

 The big bang model is problematic in that it’s philosophical or rather theological in addressing what was there before the bang. It simply describes the concerns of a certain great cause which it can’t specify as well as doesn’t comprehend. The value of the Hubble constant which is expressed in kilometers per second per megaparsec initially set by Hubble himself, since then has been revised repeatedly and has brought problems in astrological theory regarding the continued recalibration.

Hubble constant can’t be measured precisely as the speed of the mass of an electron or light. Apart from questions on its variation during the past, there exists simply no consensus on its value at present. (Thompson, B., Harrub, B.May, B, 2003). As the expansion of the particles of the gas cloud takes place outwardly, it cools. Controversy also exists on temperatures in the early universe (Parker, B. R, (2013). While the researchers would perceive the universe’s early development, they have also been in search of proof of its quick inflation.

From the research, it was found out that in the earlier latter after the emerging of the universe; the universe ballooned quicker in comparison to the speed of light. The universe is not only getting bigger but attaining faster while inflating. Hence as time goes by no one will be capable of spotting additional galaxies from earth or any other vantage place within the earth. As per the multiverse ideal, different universes will coexist amongst each other as bubbles are placed side by side. Therefore in the first big push of inflation, various parts of space-time grew at different rates.

The big bang model refers to an attempt that explains what had happened right from the beginning of the universe. Research in astronomy also in physics has given evidence yonder reasonable doubt as to how the universe emerged and how it began. Therefore, the big bang model provides information on the happenings during and after that moment.
