Theoretical cosmologists spend much of their time perfecting what is now known as the Big Bang theory. Big Bang theory to explain the early universe that will be hit by an infinitely small point. In a small volume, all matter and energy is concentrated until its contents exploded in both the smooth expansion or explosion of violence which are very energetic planets, stars and galaxies formed. Originally this theory had competition from what is called steady state theory, in which the universe is forever expanding and new matter and energy spontaneously in the space left by the receding galaxies. However, empirical observations directed astronomers and scientists into the acceptance of big bang model.

In the early twentieth century the American astronomer Vesto Slipher and the German Carl Wirtz some important astronomical discoveries. Using spectral analysis, Slipher solve the gas mixture in the atmosphere of planets and nebulae. This shift is simply a change in the wavelength of light emitted by the object that the investigation of a longer wavelength. Wirtz same redshift catalog of many nebulae which he chose to study.

Contemporaries show that a new general theory of relativity Einstein published in 1916 is not compatible with the universe ‘static’ space of time. This theory predicts expanding or collapsing universe but not fixed cosmos. To fix what is considered a “flaw” in his theory he joined the list of the cosmological constant known as lambda to force the static universe into reality. Einstein’s vision of perfection in the space time continuum change has brought a dead end as far as Aristotle’s notion of perfection, the great philosopher into the error to believe in a static Earth at the center of the universe.

But even with the addition of the cosmological constant lambda, the universe was still found to be unstable and this matter will then be viewed by Einstein as the “biggest mistake.” Cosmological acrobatics behind him, Einstein gave the stage to others for a clearer understanding of the theory itself. A few years later, Friedmann published his findings in “possible worlds with constant negative curvature of space.”

Reverend Father Georges Lemaitre Enter, a Catholic priest from Belgium. Lemaitre published his theoretical ideas between 1927 and 1933 and speculated that the movement of the validity of the atomic explosion fog its cosmic Super displayed. Unfortunately, he also mistakenly believe that cosmic rays will effect after the big bang of super atom. Cepheids that have identical cycle time again brighten the dark and bright luminosity that also have identical or nearly identical.

This way no Hubble discovered that the nebulae or galaxies exhibited a galactic red shift, in other words, that galaxies are far away from us to decline at a rate directly correlated to the distance between our perspective and the universe under investigation. The results of this study is now known as Hubble’s Law. Hubble’s Law depends on shifting the wavelength of light, and after being appointed in 1929, later proved repeatedly. Furthermore, the Hubble constant has been recalculated to a value of more ‘perfect’ and retain a great opportunity to “recalculate” in the future based on new observations. Static Earth from Aristotle to Einstein’s greatest mistake, the constant which forces a static universe, we have only the wisdom of our weak minds.
