And in the beginning, there was...the big bang (BB). For some unknown reason, null space that existed before the BB tore and released 100% energy into the null. Immediately that energy began to cool and within less than a second, the first proto mass (bosons) began to sort-of gel out as our known universe cooled.

Photons soon followed and...let there be light. Photons have been around for about 13-14 billions years, which is why we can only see 13-14 billion light years out into the universe, and that is what we call the known universe. There's no telling what's beyond.

The cooling process has continued up through now and, all the while, the temperature of our known universe gets lower and lower. Right now it's about 4 deg Kelvin, more or less. That is, it's approaching absolute zero, 0 deg Kelvin. Whether it will actually reach or just approach zero is a matter of debate. In any case, the useful energy of our universe is petering out; and one day, trillions of years from now, the universe could snuff out like a burned out candle.

The standard model explains the BB as a singularity in the fabric of null space. Singularity is best described by 1/0 --> infinity. We all know we cannot divide by zero because we get a boundless value called infinity. Well, if null space was nearly divided by zero (which the standard model says it was), then that would explain the nearly infinite energy released. A sort of something out of nothing deal.

String theory was invented in part to get rid of the point particles and the singularities they cause in the extreme. In this theory, the 0 dimension points are replaced by vibrating strings 1 Planck length long (about 10^-33 cm long). So, in the extreme, when the BB would have its origin, there is no singularity due to the Planck length limit. [See source.]

Even so, there is enormous energy released because we approach near zero. And one WAG is that enormous energy came from two or more parallel universes colliding and rebounding. That change in momenta would release the levels of energy posited by current BB models.

Of course, this begs the question; where did these parallel universes come from? But, string theorists speculate they can some day cross the BB and into the pre BB universe because, unlike the standard model, there are no singularities and resulting infinities to cross.

The current leading theory is called "inflation". Many models of inflation claim that there is one or several "scalar fields" in the universe that essentially assign a number to every point in space. For example, the scalar field S might have the value S=4 at a point near earth, and S=30 in the Andromeda galaxy. The value itself isn't really what matters so much as the energy stored in this scalar (number) field S. Some function of S determines the energy of the field at every point. An example of such a relation would be E = S^2. So, if S=0, the energy is zero. If S=2, the energy is 4, and so on. Inflation (simplified a bit, as you can imagine) argues that, perhaps the universe was created everywhere with one value of S that is not at the minimum energy. Soon, the universe began to change "phase" not unlike water freezing, where S dropped to the nearest minimum in energy, forming bubbles across the universe. As these bubbles collided, they released tremendous amounts of energy, perhaps all the energy and matter that exists in our current universe in the form of hot, exotic particles. As the universe grew and cooled, the particles decayed mostly to the photons, protons, neutrons, and electrons that we primarily observe today. It was the process of Big Bang nucleosynthesis, along with the later formation of stars, solar nucleosynthesis, and supernovae that provided us with the heavier elements that make up solar systems, planets, and people.

The condensation of matter from the energy of the big bang is a consequence of baryogenesis and symmetry breaking. This is moderately well understood from the standard model.

The origin of the energy in the big bang is not known, and may notbe knowable because of a phenomenon sometimes called cosmic censorship. This arises because nothing - not even the laws of physics themselves - can be traced across a singularity, and the big bang was a singularity.

Do you want the Big Bang Theory, or the even more descriptive M-Theory? M-Theory involves interdimensional membranes colliding into each other, which then produced energy, which then produced matter.

whats up now, don't be *that guy* and insult human beings's intelligences and common vocab know-how purely considering which you disagree with them. no longer cool. to respond to your question: confident. i'm able to admit that that's a danger that God does not exist. For a huge form of motives, i think of that He does exist, yet to disclaim even the prospect that i'm incorrect is... silly. IMHO, in case you detect an atheist who denies the prospect that God exists, its purely comparable to a theist who denies the prospect that He does not... neither have somewhat concept approximately issues adequate.

Big bang theory (Fact)--large explosion created all matter and energy, this is measurable back to a time--before that it is anybodies guess.
