Big Bang Theory

1. Introduction
Education is common in today's society. I believe that everyone is clear about the birth process, such as how the fertilized eggs develop into fetuses. But you ever wondered how the universe began it? It's the birth process is then? We then is to explore this issue. Over the past few decades, there are two theories to explain the birth of the universe just stuck. One of these is the so-called Big Bang theory, while the other person is known as the static theory. Big Bang theory first proposed by George ‧ Lemaitre, and later by George Gamow ‧ continue. Big Bang theory holds that the universe is expanding, the universe is in the past a given time and temperature by a very high density of the original state of evolution. On the other hand, the static theory mainly by Einstein and later by Fred Hoyle ‧ advocacy. Static theory of principal that if the expansion of the universe, then there must be new in order to maintain the average density of material involved. After World War II, debate is intensifying. But in the end, victory is always one big bang. In the following few sections, we will discuss a number of observations support the Big Bang theory of evidence.

2. Hubble's law and expansion of the universe
Edwin Hubble and Milton ‧ ‧ Emerson, through the amendment after a long period of observation, that the red shift of light from distant galaxies and their proportional to the distance. Redshift refers to the light from those distant galaxies decrease the frequency of the phenomenon, which occurs mainly from the red shift of the Doppler effect, simply because the distant galaxies are moving away from Earth Ershi the frequency of light down and away from The faster the frequency the more obvious the phenomenon of decline. So, when Hubble discovered that the galaxies away from us the more the more obvious its redshift, they draw their conclusions from the faster. The number of Hubble's law type is as follows:
v = Hd
v: velocity of galaxies from... [continues]
