But it's not. I've never seen anyone (but you) call a nearly infinitely dense singularity "nothingness."
oh I was just going off of what a 60 something year old man, who think he knows everything, told me. thats all.
just for this thread. I would like the big bang theory presented. Its not that I dont want to go find it myself, I simply want to see which version of the big bang you believe in.

Why the **** is this even a thread then? You think some loon yelling in the middle of the streets that we're all sinners and are goin' to hell has any less authority than a "60 something year old man, who thinks he knows everything"? Both have worthless, stupid, ignorant views, with no facts, history lessons, or valid points. Please stop wasting ATS server space for **** like this. stdy up, have some key points/links, and present them in a descent well thought out post. Criminy!

Everything in this universe and everything on this earth is made up of matter and energy. where did it all come from? well evolutionary scientists have come up with a theory called the big bang theory.
it theorizes that a large quantity of nothing decided to pack tightly togther and. then, explode/expand outward into hydrogen and helium.
This gas is said to have flowed outward through frictionless space
1. a tiny bit of nothing packed together and then exploed to form everthing in the universe we see today? that is a fairytale is I ever heard one.
2. nothingness cannot pack together and form something. it has no way to pack together.
3. a vacuum has no density, it is said that nothingness got very dense and thats why it exploded/expanded.
I simply asked for you to present them to me so that I can know all version of the big bang. I only know of one.

about 20 billions years ago, all the matter in the universe was gathered and compressed into a region, no bigger than the period at teh end of this sentence.
and then it spun faster and faster. then one day, it exploded.
4.6 billions years ago, the earth was formed
im just looking for all of the other versions.
The Big Bang Model rests on two theoretical pillars: [...]A key concept of General Relativity is that gravity is no longer described by a gravitational "field" but rather it is supposed to be a distortion of space and time itself[...]That is, the matter in the universe is homogeneous and isotropic when averaged over very large scales. This is called the Cosmological Principle.[...]Given a law of gravity and an assumption about how the matter is distributed, the next step is to work out the dynamics of the universe - how space and the matter in it evolves with time. The details depend on some further information about the matter in the universe, namely its density (mass per unit volume) and its pressure (force it exerts per unit area), but the generic picture that emerges is that the universe started from a very small volume, an event later dubbed the Big Bang, with an initial expansion rate.
Please avoid the following common misconceptions about the Big Bang and expansion:
- The Big Bang did not occur at a single point in space as an "explosion." [...]That region of space that is within our present horizon was indeed no bigger than a point in the past. Nevertheless, if all of space both inside and outside our horizon is infinite now, it was born infinite. If it is closed and finite, then it was born with zero volume and grew from that. In neither case is there a "center of expansion" - a point from which the universe is expanding away from.
- It is beyond the realm of the Big Bang Model to say what gave rise to the Big Bang. There are a number of speculative theories about this topic, but none of them make realistically testable predictions as of yet.
When Einstein formulated the general theory of relativity, he found that it was incompatible with a static universe; the equations predicted that the universe must either be expanding or shrinking. [...]Extrapolating this expansion backwards, we find that at a specific time in the past the universe would have been infinitely dense[...]The big bang model has been extremely successful at explaining known aspects of the universe and correctly predicting new observations. Nonetheless, there are certain problems with the model. There are several features of our current universe that seem to emerge as strange coincidences in big bang theory. Even worse, there are some predictions of the theory that are in contradiction with observation. These problems have motivated people to look for ways to extend or modify the theory without losing all of the successful predictions it has made. In 1980 a theory was developed that solved many of the problems plaguing the big bang model while leaving intact its basic structure. More specifically, this new theory modified our picture of what happened in the first fraction of a second of the universe's expansion. This change in our view of that first fraction of a second has proven to have profound influences on our view of the universe and the big bang itself. This new theory is called inflation.[...]
An element is defined by the number of protons in a nucleus—one for hydrogen, two for helium, and so on. For roughly three minutes after the big bang the temperature of the universe was so high that protons and neutrons couldn't bind together into nuclei; the particles all had so much energy that the forces that hold nuclei together were too weak to make them stick to each other. Thus for those first three minutes the only element in the universe was hydrogen, i.e. single protons not bound to anything else. (A neutron with no proton is not considered an element.) As the universe expanded and cooled it eventually reached a temperature where the protons and neutrons could bind together, and different elements were formed. The formation of these nuclei from their constituent particles (i.e. protons and neutrons) is known as nucleosynthesis. Nuclear theory is well tested and understood. By applying it to a homogeneous, expanding medium at high temperature we can predict what relative abundances of different elements should have emerged when these nuclei were formed in the early universe. It turns out that only the three lightest elements, hydrogen, helium, and lithium, would have been able to form at that time. All of the heavier elements were formed much later in stars, and currently make up a tiny percentage of the matter we see in the universe. The predictions of the relative abundances of these light elements accurately match the observational data. This match is particularly important because it strongly suggests that the big bang model is an accurate description of the universe at least as far back as nucleosynthesis, i.e. three minutes after the predicted moment of the big bang. All of the other evidence for the theory, such as the microwave background and the motions of distant galaxies, relate to the universe at much later times, so we have no direct evidence for the accuracy of the big bang model before nucleosynthesis.

The Big Bang theory was originally developed in the late 1920s by Georges-Henri Lemaître, a Belgian Catholic priest and astronomer, an early advocate of solutions to the general relativity field equations which predicted our universe was expanding. (For cosmological theories to be taken seriously, they must pose possible solutions to Einstein's general relativity field equations.) Though the expanding-universe solution to the field equations was derived by the Russian cosmologist Alexander Friedman in 1922, Lemaître was the first to realize that a continuously expanding universe implies that at some point in the past the universe must have been much denser and smaller, even atom-sized.

just because someone is catholic does not mean that is what they believe in. supposedly hitler was a catholic, but he went out and killed a bunch of people for no reason whatsoever, and killing is against the 10 commandments unless you have justification such as a war, or fighting for your freedom. there was nothing wrong with the jews, they didnt do anything. the same with stalin and pol pot.
I also think that the catholic religion is lost in their own beliefs as well as mislead by many of the religious leaders, thats just my opinion.
and it doesnt matter who thought of it what matters is who uses it and supports it.

some book that has been edited and re-edited over the last 2000 years.

not edited, but tanslated. not edited
and there are many things in the bible that can be explained with science.
someone tell me what the big bang is, in short. give me the most up to date version of the big bang that is most commonly used and most agreed on.
