This is called a flat Universe. The third option has almost been ruled out, but there is always a possibility. If the universe is denser than we think, gravity will eventually become stronger than the expansion, perhaps resulting in the universe collapsing in on itself in a ?Big Crunch?. We may not know where our Universe is heading, but the Big Bang theory helps us understand where we have come from. Although there are still many unanswered questions, there is plenty of time left in this young Universe, and plenty of places to explore.
It is not yet possible to give a definitive answer to the questions: what was the Big Bang and why did it happen? However, there has been a great deal of speculation recently on this subject, and it may not be long before a definitive, or almost definitive, answer will be declared. For the moment we will simply take the Big Bang as it is given, a huge explosion in which time and space began expanding. It is important to realize that space itself originated in the Big Bang. IT is tempting to think of the universe before the Big Bang as being a vast, infinite, expanse of empty space, like the space between the galaxy clusters today.
It, in fact, wasn’t an explosion, but instead the space was expanding as a whole. An explosion implies that something exploded, or expanded, from one center point outward into space. As the Big Bang Theory implies space and the universe began by expanding. The universe is still continuously expanding. (Maskowitz) The Big Bang Theory would be completely pointless without reasonable explanations to support it.
Astronomers became certain that the universe began with the Big Bang Theory. The first observation was that it was expanding that means that would separate galaxies and they are becoming lager. The galaxies use to be extremely close together before some kind of explosion which is the big bang theory. Second the big bang theory explains the “Abundance of helium and other nuclei like deuterium in the “Abundance of helium and other nuclei like deuterium in the universe. Third astronomers could not actually see the comic background radiation.

One can also calculate the density required such that the Universe will eventually stop expanding. That density is called the critical density, and the ratio of the observed density to the critical density is given by the Greek letter omega. If omega is less than one the Universe will continue expanding until it is so large that it dies a cold death.
These new atoms were called baryons. Baryons consisted of photons, neutrinos, electrons, and quarks. These particles became the foundations of every diverse particle in our universe. Baryons had paved the way for the more common particles we know today, such as protons and neutrons. When the universe had cooled down a bit, protons and neutrons began to form.
The universe has tremendous amount of electrons that permits to big protons and neutrons. The electrons and protons combine form atoms. This all happened in one second. Theory states that after universe first began, the comos ballooned farther than the speed of electricity. This doesn’t violate Albert Einstein’s speed limit which states that light is the MAX that anything can travel.
There are various viewpoints on what happened before the Big Bang, however it is a very big question. Astrophysicists have claimed that there is no answer to what happened before the Big Bang however there are several theories. It is supposed that one can hypothesize as there are no tools to reach the truth. A profound issue that is easy to understand is the distinction between if the universe is finite or infinite and that’s either in terms of time and space. Other questions deal with whether the universe goes on forever or does it have a limit?
What was before this event is not known to any human being and is a matter of pure speculation. This occurrence was not a conventional explosion but rather an event that expanded all of the particles of the “baby” universe rushing away from each other. There were actually no galaxies before that of the big bang but it was more like it started the process of creating all of the galaxies that we know today.

Maybe the one who is reading this will be the one to prove the Big Bang theory, the theory of inflation, and the theory of gravitational waves.
However, we detected a faint glow after the Big Bang occurred 13.7 billion years ago. The theory in which the universe began with the Big Bang is one of the most profound discovery humans have ever made. The Big Bang theory is however a global description of the beginning of time, matter and space. Today, physicists have consistent theories about the history of the universe down to only a trillionth of a second after the universe's birth or even earlier.
