The Big Bang theory is an effort to explain what happened at the very beginning of our universe. Discoveries in astronomy and physics have shown beyond a reasonable doubt that our universe did in fact have a beginning. Prior to that moment there was nothing; during and after that moment there was something: our universe. The big bang theory is an effort to explain what happened during and after that moment.

According to the standard theory, our universe sprang into existence as "singularity" around 13.7 billion years ago. What is a "singularity" and where does it come from? Well, to be honest, we don't know for sure. Singularities are zones which defy our current understanding of physics. They are thought to exist at the core of "black holes." Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of infinite density are called "singularities." Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something - a singularity. Where did it come from? We don't know. Why did it appear? We don't know.

After its initial appearance, it apparently inflated (the "Big Bang"), expanded and cooled, going from very, very small and very, very hot, to the size and temperature of our current universe. It continues to expand and cool to this day and we are inside of it: incredible creatures living on a unique planet, circling a beautiful star clustered together with several hundred billion other stars in a galaxy soaring through the cosmos, all of which is inside of an expanding universe that began as an infinitesimal singularity which appeared out of nowhere for reasons unknown. This is the Big Bang theory.

The Big Bang theory suggests (it's not a fact you see, like some people seem to think) that all matter in existence came from an infinitly small, infinitly dense ball of matter. This ball became so dense that it couldn't contain itself anymore and it exploded "about 13.7 billion years ago" according to Wikipedia. The sub-atomic particles it released then collected together into atoms then into molecules etc, untill they started forming stars, planets etc. Supposedly, this is why the universe is still expanding from its centere today. The full details can be found at sites like Wikipedia, NASA.gov and other science websites and science books in the library and bookstores.

It's all a bunch of nonsense however, because despite all their clever computer models, equasions and impressive sounding theroies; they still haven't answered the questions that fire huge holes in the Big Bang Therory. Questions like: "Where did the infinitly dense ball come from?" "Where did all the subatomic particles in the ball come from for that matter?" "How could all the complex systems now in place in living and nonliving things possibly have simply 'evolved' from nothing but random explosions and collissions?" And so on. One "answer" to the "where did the ball come from?" question that I have heard is that the ball came from a Big Squish. In other words, all the matter in some previous universe got smashed down into this infinatly dense dot somehow. The idea is that the universe is in some kind of feedback loop where it's created and destroyed in a cycle of billions of years.

To all that I say "what a load of baloney". Why would anyone want to believe that? Some people ask me how I can be a scientist and a Christian at the same time if I don't believe in the Big Bang and Evolution. I tell them that their so-called science is nothing more than a religion disguised as real science. You tell me, which one sounds more possible: An infinitly dense ball of stuff explodes and condenses over and over again but no-one knows what started the cycle in the first place and where the matter in the ball came from. OR An all knowing, all powerful God who exists outside of time and space, created all of the universe and everything in it by the power of His words. You tell me how either one of these is real "science". By real science, I'm talking about the classic definition of "The observation and study of objects and phenomena, especially those which can be reproduced under controlled circumstances." You can't reproduce the events or mechanisms that created the universe nor those that supposedly cause evolution. Every attempt at doing so has been found out to be a fraud.

HI.The Big Bang theory is exactly that a 'theory."According to the scientists a small very dense ball of "matter"suddenly "appeared" then exploded to form the universe.Where did this ball of condensed matter come from.They don't know.I thought all scientific experts only deal with facts.But there not too concerned how the matter got here.There quick to point out that they know what happened a fraction of a second after the Big Bang occurred.Some how it doesn't make sense.
Cheers.

The universe began a singularity of infinate density and temperature about 13.5 billions years ago. Since that instant, the universe has been expanding and cooling ever since. From this, all matter and energy has been formed at the same time and has been evolving into the universe that we see today. Obseravtional factors are back up by many complex mathematical equations that only a few Einstein like sceintists understand, but the basic picture of the expanding universe is a given fact.

The general theory is that light waves in distant galaxies seem to be longer in length than those observed on or near earth. This leads some "scientists" (which are, in truth, only speculators) to proclaim that all matter is moving farther apart as time develops, hence, an explosion, or "bang" hypothesis.
What the theory does not address, albeit, is the origin of matter. When addressing the "big bang" theory, one must ask themself from whence came the matter necessary to initiate this universal explosion.

The universe started as a single space-time pulse that came into existence about 10 to the minus 95 seconds from zero.
As the pulses continued the entity expanded at an accelerating rate for about one-thirty billionths of a second.
At this time it had a radial velocity of the speed of light.
It was about the size of a marble but it contained everything necessary to evolve into a universe like the one we see and experience to-day.

the big bang theory says that at the beginning everything was so small (at singularity)and a large explosions was caused and because of that the universe was formed (was expanded to be big enough as it is now)
and due to the large amount of energy released the universe is still expanding

Scientists believed that the universe is spreading farther apart infinitely because of a huge explosion that happened after the universe was created. Everything was believe to be one compacted sphere until it all exploded, atoms began forming as protons, neutrons, and electrons smashed together, and planets and other bodies in outer space formed.

ill give you the short answer. basically, everything that is in the universe was in an area so small you could hold it in your hand. the whole universe and everything in it expanded and continuse to expand to this very day. as the universe expanded it cooled and allowed stars and galaxies and everything else to form. read any book by timmothy ferris and it will help you understand things a little better. my favorite book of his is "the whole shebang" good luck and i hope this helped!!!!!!

Think of a star forming, and going super nova, now picture that on a grand scale
