The Big Bang expresses the understanding of an evolving universe from a one dimensional singularity to the traditional fourth dimensional model of our ever-accelerating universe. In general, existence came into being upon the dimensional unfolding of Space and Time from the condition of a singularity (formed during a degree of convergence in Space and Time) into the reality of our traditional fourth dimensional SpaceTime continuum. The Big Bang is more a reference to an unfolding evolutionary model of existence in which SpaceTime allows for the integration of positive matter (or an explosion of multiple dimensions from a more singular dimensional containment; i.e. singularity). The concept of this singularity provides for a temporal confinement in the unification of all the primary forces of the physics (i.e., gravitational, electromagnetic, strong and weak). Immediately after this creation event, the evolutionary expansion of the primary quantum forces provide for a dense and hot plasma soup which expands to permeate its unfolding dimensional containment. The universe continued to decrease in density and fall in temperature, hence the typical energy of each particle was decreasing. Over a long period of time, the slightly denser regions of the nearly uniformly distributed matter gravitationally attracted nearby matter and thus grew even denser, forming the four possible types of matter are known as cold dark matter, warm dark matter, hot dark matter, and baryonic matter. Eventually gas clouds, stars, galaxies, and the other astronomical structures we observe today, began to precipitate in the expanse of the expanding universe. Note: The details of this process depend on the model used, and the amount and type of matter, and localized quantum instabilities present to facilitate the accretion of positive mass density in the Universe.
The universe started to expand very quickly immediately after the Big Bang.
But there was no Bang, for there was no atmosphere.
Nor was there any light yet, for elements had yet to be formed.
Big Bang is just a name.
Nothing.
It is a common misconception that the Big Bang was an "explosion" of a small volume of matter into empty space. It was actually of expansion of space itself.
Imagine a balloon, with ink dots, that is growing in diameter. The space within our Universe is like that balloon, and the ink dots are like galaxies. As the balloon / space expands, every ink dot / galaxy gets further and further apart from every other ink dot / galaxy. But there is no center from which all ink dots / galaxies expand from; and every point on the balloon / in our Universe is equal to every other one.
A common mis-understanding, not helped by popular presentations of the Big Bang and even many scientists who should know better, is that our Universe is like ink splattered on that balloon, expanding out from one point. That simply is not the case.
Note that this balloon analogy fails because (1) a balloon surface is two-dimensional, and our Universe has three main spatial dimension, (2) the balloon is expanding INTO something outside itself, and our Universe is not (as best we can tell), and (3) a balloon surface is curved, while the space in our Universe is perfectly "flat" (mathematically, a 3-D object can also be "flat) to within .6% .
The Big Bang was NOT an explosion of matter into empty space from one central point. Rather, it was an expansion of space itself, with matter becoming less and less dense as space expanded.
Think of space as a balloon, and ink on the balloon as matter. Big Bang Cosmology does NOT say it was like a splotch of ink hitting the balloon, with the ink spreading out on the surface. Rather, it was like the balloon has been expanding, resulting in the ink spots already on the balloon becoming further and further apart.
Note that the above analogy itself fails because (1) a balloon's surface is a two-dimensional surface, and the space in our Universe is 3D, (2) a balloon's surface is curved, while the space in our Universe is flat (Yes, it's hard to imagine a 3D object being "flat," but the math works out just fine), (3) the balloon is expanding into something (the air around it), while our Universe is just expanding. Again, it's hard to imagine something expanding without taking space away from somthing else, but the math works out.

I'm not certain, because as an instruction on what happened at the Big Bang, it's COMPLETELY WRONG. The BB was NOT an explosion of matter from a central point into empty space, like a firework. It was an expansion of space itself, taking matter with it, with no central point at all.
The big bang happened something like 14 billion years ago. As an instant in time that is true, as a process it is still happening at every point in space as that point expands into a finite volume and drags matter and energy with it.
Your question betrays a common misconception about the Big Bang -- that it was an explosion of dense matter into empty space. Despite many popular presentations that suggest this, it is SIMPLY WRONG. The Big Bang was an EXPANSION of space itself, and not into anything "out there," that took matter along for the "ride." The stuff that eventually became matter, as well as the space that was expanding, was there from the earliest time that we understand what was going on. Which is pretty far back -- we can understand our Universe from about 10^-32 seconds after the Big Bang and onwards after that. The time before then, however, is as unknown to us as the origin of lightning in the sky. So, if your question is, "What was the origin of the space and the stuff that eventually became matter?", then the answer is simple: we don't know.
NoAnswer:Present thinking is that the Big Bang created space, time and energy/matter. As a consequence at the expanding edge of the Universe there is a region of no space or time.
The big bang began the expansion of spacetime with great rapidity. The Universe began with the Big Bang. In other words both space and time began at the big bang. The big bang started the Universe from the point t=0.

The person who discovered space chose to call it that, instead of bang. Its just a name, so it doesn't matter.
Scientists believe that all matter resulted from the big bang.

the "big bang" became existent, thus expanding space as it goes.
The spread of mass and space. The matter-antimatter collisions HAD to happen after the big bang.
No. An explosion is an expansion of matter from a central point of high density to outer points of lower density. This is NOT what happened during the Big Bang, despite numerous popular presentations to that effect. The Big Bang was NOT an expansion of dense matter from a central point into empty space. It was an expansion of space itself.
No, when the big bang happend dark matter and dark energy came. Dark matter expands space even as we speak.
The big bang happened something like 14 billion years ago. As an instant in time that is true, as a process it is still happening at every point in space as that point expands into a finite volume and drags matter and energy with it.
a theory that says that the universe began with a super-powerful explosion The word "explosion" carries a sense of something of large density expanding from a center point into a region of low density. This is NOT what happened during the Big Bang, despite many popular presentations that imply such an event. The Big Bang was NOT matter expanding from a center point into empty space, it was the expansion of space itself. There was nothing that this space was expanding INTO, it was just expanding.
There was no matter or energy prior to the Big Bang creation event. Consequently, there was no Earth and there were no cavemen (or cavewomen).
According to the scientists big bang is the main reason of the creation of this universe. after the big bang only the matter space and time came into being
