Despite the name of the theory, the Big Bang Theory does not explain the bang of the Big Bang. It tells us more of the aftermath of the bang. The actual cause and circumstances of the bang are unknown to scientists. A major problem is the singularity. At the singularity, all the laws of physics break down and what happens there is anybody's guess.

A popular theory about this singularity is called the Inflationary  Model of the early Universe. It goes like this.....

The singularity is a very tiny ball. Inside this ball - at this pressure -  is  virtually vacuum.  They say virtual since it is empty save for things called gravitational waves. These waves pulse back and forth with levels of "high" energy and levels of "low" energy. The Inflationary Model theorizes that these waves get stuck in "high" energy mode.

This high energy causes a bulge on the side of the primordial ball of space. The bulge of high energy quickly expands at an exponential rate.....going from the size of a proton to roughly that of a basketball in  10^35 of a second.
(That's:  0.00000000000000000000000000000000001/second)
The high energy would soon lose its punch, and the whole ball of early space would explode in a massive fireball.

Now this helps explain several questions I asked in previous pages.

1. 1.   The bulge helps to provide for an uneven explosion, which would lend to the formation of stars and galaxies.
2. 2.   Provides for the presence of the Microwave Background Radiation since everthing would be close enough together, for a long enough period of time, for energy to reach all parts of the ball.

1. 1.   The Inflationary Model calls that the universe be what is called a "flat" universe. This has yet to be proven and no evidence that I am aware of, points to this. As current observations  show today,  the universe is actually quite "open".
2. 2.   The Model also calls for more matter to be in the universe than what is actually there.......MUCH more. Observations show that there is only 50 - 80 percent of the amount needed for Inflation to work. So unless there is a large amount of matter hiding away somewhere, the Model needs more tweaking.
3. 3.   The Inflation Model also calls for the minute density fluctiations in the Microwave Background Radiation to cluster around what is called Gaussian distribution. This distribution is like a bell-curve showing how matter clumps in a random explosion....in essence, it describes the most natural random dispersion of matter in an explosion possible. Observations now taken by the COBE (Cosmic Background Explorer) satellite show us that the fluctations vary too much and indeed do not follow Gaussian distribution. Granted these varied fluctuations are in a particular part of the sky and are on the limits of the satellite's resolution, but it is enough to have scientists questioning the viability of the Inflation Theory. The questions come in becuase if the universe is not as random or as even as thought by Inflation, then Inflation could not be the answer.
