The big band theory
that portion of the universe that we can see in principle, given the finite age of the universe
The CMBR did not reveal anything DIRECTLY about the age of our Universe. However, its spectrum and isotropy are almost perfectly as predicted by a Universe that began to expand about thirteen billion years ago -- a timeline given by the Hubble Constant. As such, it gives extremely strong support to that timeline.
The COBE (Cosmic Background Explorer) was important to the big bang theory because it provided very precise measurements of the cosmic microwave background radiation. These measurements confirmed the existence of this radiation and provided strong evidence for the theory of the big bang, which suggests that the universe began with a hot, dense, and expanding state. The COBE's findings supported the idea that the cosmic microwave background radiation is a remnant of the early stages of the universe.
Hubble was an astrophysicist in the early 20th century. He helped discover the rate at which the universe is expanding, which is now given by the Hubble constant. (H0=69km s^-1 Mpc^-1)
According to the Big Bang theory and its newest related data, 13.75 ± 0.11 billion years. The reason we know the universe has a beginning, is because it is dark. Through more complex analysis, we can conclude the universe's past is not infinite.There are other estimates of the age of the Universe, some of which vary significantly from the one given above. This is the best scientific estimate available to us today. Many estimates are not scientifically based.See related links.
The big band theory
It is "The Big Bang Theory."
This was given the name Big Bang Theory by Fred Hoyle.Possibly partly in jest, for at the time he was promoting a Continuous Creation Theory of his own, which he subsequently abandoned.
The Big Bang Theory is the name given to the theory of cosmic expansion. The idea is of an ever expanding universe. It posits that at some point all matter in the universe was contained within one point.
In theory, yes. I suggest you research "newton's cannon".
Yes - a deterministic theory means that given initial conditions, it yields a precise answer for future time. This does not happen in quantum physics. Read the Feynman lectures on physics volume 3 for more information.

Scientists who study the universe are known as cosmologists.
