Big bang
The knowledge itself that the universe exists has not satisfied mankind's curiosity for further understanding. One of the most common asked questions is how the universe was created. Most people believed that the universe had no beginning or end.The Big Bang theory is the dominant scientific theory about the origin of the universe. According to the Big Bang the universe was created about 10-20 billion years ago from a tremendous cosmic explosion that send matter and energy in all directions. At the point of the explosion all the matter of the space was contained at one point.Before the Big Bang the entirety of the universe was contained into the confines of an atomic nucleus. This is known as singularity and this was the condition of the universe before its creation when time and space did not exist.In 1927, the Belgian priest George Lamaitre was the first person who proposed that the universe began with the explosion of a primeval atom. The proposal of that theory came due to the observation of red shift in distant nebulas by astronomers to a model of universe based on relativity. Nevertheless, the origin of the Big Bang theory is credited to Edwin Hubble. Hubble made the observation that the universe is continuou
Moreover many spiral galaxies have been observed at a large distance and therefore from a time closer to the Big Bang. Joseph Von Fraunhofer a German optician and physicist who plotted the position of those lines also noticed these dark lines. Recently, according to the "http://liftoff. These problems tend to oppose the Big Bag theory and prove that it is false. According to the Big Bang theory the temperature of the background radiation was much higher in the past. But that would indicate that they have had time for even fewer rotations, which is not enough for a galaxy to achieve a spiral shape. The noise originated from cosmic radiation and had a temperature of 3 oK. The red shift on the sun, for instance, is not Doppler effect since the sun is not moving away from the earth. These two materials destroy one another creating pure energy. Also, the theory predicts the existence of cosmic background radiation and the theory received strong confirmation when this radiation discovered in 1964 by Arno Penzias and Robert Wilson. html" this shift shows a variation in magnitude that correlates with the number of electrons along the line of sight. In 1814, William Wollaston an English physicist, who launched the spectroscopy, noticed that there were some dark lines that separated the continuous spectrum of the sun.
