»The beginning - big bang theory!«

Some scientific equation maybe that just randomly burst into the big bang.

13.7 billion years ago, the entirety of our universe was compressed into the confines of an atomic nucleus. Known as a singularity, this is the moment before creation when space and time did not exist

3.apparently since the density was infinitely compressed and infinitely small there was no space...but in geometry does a point take up space ot volume?

A spatial point is an entity with a location in space but no extent (volume, area or length). In geometry, a point therefore captures the notion of location; no further information is captured

The Theory of Hyperspace
According to Superstring theory, before the Big Bang, our cosmos was actually a perfect ten-dimensional universe, a world where interdimensional travel was possible. However, this ten-dimensional universe "cracked" in two, creating two separate universes: a four- and a six- dimensional universe. The universe in which we live was born in that cosmic cataclysm. Our four-dimensional universe expanded explosively, while our twin six-dimensional universe contracted violently, until it shrank to almost infinitesimal size. This would explain the origin of the Big Bang. If correct, this theory demonstrates that the rapid expansion of the universe was just a rather minor aftershock of a much greater cataclysmic event, the cracking of space and time itself. The energy that drives the observed expansion of the universe is then found in the collapse of ten-dimensional space and time. According to this theory, the distant stars and galaxies are receding from us at astronomical speeds because of the original collapse of ten-dimensional space and time.

This theory predicts that our universe still has a dwarf twin, a companion universe that has curled up into a small six-dimensional ball that is too small to be observed.

The superstring theory, being a completely finite theory, gives us deeper insight into the era before the Big Bang. The theory states that at the instant of creation, the universe was actually an internal linkinfinitesimal ten dimensional internal linkbubble. But this bubble (somewhat like a soap bubble) split into six- and four-dimensional bubbles. The six-dimensional universe suddenly collapsed, thereby expanding the four-dimensional universe into the standard Big Bang.

Type of possible space #1: A 10-dimensional universe made up of the normal three dimensions of space, plus one of time, plus six-dimensional Calabi-Yau manifolds located at every point in normal three-dimensional space.

Excellent question #1: What the hell is a Calabi-Yau manifold?

Attempted answer #1: It is arguably impossible to imagine what a Calabi-Yau manifold is, because it has six dimensions. But let's try anyway. A Calabi-Yau manifold looks kind of like a balled-up piece of paper, except it's one whose curves and twists and turns are intricate and Möbius-like, looping back over and around themselves with clear disdain for Euclidean geometry. A Calabi-Yau manifold knows no straight lines. I try to imagine myself inside one of these manifolds: I think it's probably much like a fun house, mirrors everywhere deflecting your gaze in every which direction, so that at any time you could be looking straight ahead and see, for instance, your back. Except it's not quite that -- there are no mirrors in a Calabi-Yau manifold, there is only space itself. So while you can still look forward and see your back, you could also, theoretically, throw a baseball at it, only to feel the little missile smacking your spine two seconds later. That baseball might have traveled up and around, roller-coaster-like, through six dimensions, eventually ending up at your back. A Calabi-Yau manifold is a strange thing indeed.

(Actually, recent developments in string theory suggest that there may be yet another dimension, for a total of 11, and that this new extra dimension is invisible because it is "curled up" into an infinite number of tiny loops. But to avoid further brain pain, let's stick with 10.)

Type of possible space #2: The universe as we know it is merely a three-dimensional brane suspended in a four-dimensional bulk.
Excellent question #2: What the hell is a brane?
Attempted answer #2: Here is the Powerpoint version of everything you need to know about branes:

· You live on a brane.
· A brane is like a membrane.
· Imagine the skin that forms on your soup when it gets cold. A brane is like that.
· A brane is some sort of lower-dimensional thing (the 2-D skin) sitting in a higher-dimensional space (your 3-D soup).
· Brane theory says our 3-D world is really just a brane.
· Our brane sits in a 4-D space called the bulk.
· Like so much congealed fat, we are prevented from escaping the brane and going into the higher-dimensional soup.
· Only gravity is allowed to do that.

During this creation and annihilation of particles the universe was undergoing a rate of expansion many times the speed of light

how do they explain this? i thought nothing could move faster than the speed of light?

Maybe the speed of light was different then

But is can be faster.

What is the speed of is?
