Big Bang Theory Essay Examples

The Theory of the Big Bang started from observations and scientific facts. The Big Bang theory provinces that after the “Big Bang” the existence expanded from its original pea-sized beginning to astronomical proportions. and the enlargement of the existence still continues today but at a much slower rate. In the 20th century many scientific developments were made by scientists that contributed to the creative activity of the Big Bang Theory.

Essay Example on About Big Bang Theory

In 1910 Vesto Slipher was the first individual to detect displacements in spectral lines in galaxies.

What he had discovered was the galactic red shifts. A galactic red shift is a supplanting of spectral lines toward longer wavelengths. What Slipher specifically observed was that the spectral lines of many nebulas exhibited a ruddy displacement that indicated gesture off from planet Earth.

Around 1912 Carl Wilhelm Wirtz like Vesto Slipher observed a systematic red shift of nebulae. While detecting the red shift he came to the decision that relative to the present location of the solar system the coiling nebulae is traveling off from the solar system.

He subsequently discovered that it is traveling off from the solar system at 656 kilometres per second. This provided experimental grounds that the existence was spread outing.

In 1916 Albert Einstein published his Theory of General relativity. The General relativity Theory states that gravity arises from the curvature of infinite and clip. It besides said that the existence was either undertaking or spread outing. Today the theory is used to depict gravity in natural philosophies.

Einstein’s theory was influential to the development of the Big Bang theory because it created the cosmogonic invariable.

Alexander Friedmann used Einstein’s theory in order to come up with his ain findings. He applied general relativity to cosmology without utilizing the cosmogonic invariable. He found solutions to field equations that created the preliminary work of the Big Bang Theory. His solutions created the Friedmann-Lemaitre-Robertson-Walker Universe. Friedmann’s work was important to the promotion of the Big Bang Theory because his work showed that it is possibility of a altering existence.

Georges Lemaitre stated that the existence began with an detonation of a aboriginal atom in 1927. This thought was subsequently called the Big Bang. Lemaitre used the Friedmann-Lemaitre-Robertson-Walker Universe and Einstein’s General Relativity as a base to his hypothesis. With his hypothesis he created a theoretical account of the existence to detect the displacements in the Spiral Nebulae. With this theoretical account he was able to turn out that the existence was in fact spread outing.

Edwin Hubble discovered that other galaxies exist other than the Milky Way Galaxy. With this find it made the possibility of a “Bang” more plausible. In 1929 Edwin Hubble published “Hubble’s Law” . This jurisprudence states that the recession speed of a distant extragalactic object is straight relative to its distance. His observation concluded that the existence was one time compacted affair. His jurisprudence led to the creative activity of the Big Bang Model.

All of these scientists contributed to the creative activity to the Big Bang theory. as we know it is to be today. Many of these scientists used each other’s work I order to progress or explicate their ain observations or findings. Even though these scientists were finally able to explicate the procedure of the Big Bang they were non successful in clear uping why the Big Bang occurred.
