It is unsure because when the big bang explode, space's dimension is expanding, which means the dimension will go on forever.
Why our Universe is composed almost entirely of matter, with almost no anti-matter in it.
If you are referring to the Big Bang, I am afraid that there is not really an answer for you. Cosmology (the study of the universe and its origin) is such a recently developed science that there is yet not way to explain why the Big Bang occurred in any terms more than conjecture. It is thought to have been caused either by a collision or rubbing together of other universes, or a presence of enough room in the 'multiverse' for another universe to form. If you really want to pursue an answer to this question, the best answer I can give you is this: become a cosmologist.
Theoretically yes. String theory and M theory says that when the two universe collide together or split into two universes, that is when Big Bang occurs. However there is no evidence that Parallel universe exists.
The big bang or God created it. Mostly the big bang is the scientific reason and God is the religious reason.
First, we have no information on whether the universe will end, or if it will continue in perpetuity. It's either one or the other - and yet either answer would be astonishing. Second, we have no idea how the end of the universe might come about, or what the conditions at the end time would be, or if the concept of "after the end of the universe" has any meaning at all. One interesting concept is that of an oscillating universe; a Big Bang of expansion, with gravity overcoming everything in the end and pulling every shred of matter back to itself in a "Big Crunch". This could be the prelude to another "big bang". Each universe would be completely new and unaffected by the last.
Scientists believe the "first event" in the Universe was the Big Bang. The Big Bang Theory attempts to explain how the universe was originally created.
In the current model of the universe the big bang was the 1st thing to happen in the universe since time itself was created in the big bang.
It was microscopic. At the first moment of the bang the entire universe, that is the entire space-time continuum and all of the energy within it were spaller than an atom.
The prevailing scientific theory is that the universe started with the Big Bang.
The Big Bang Theory tells what happen at the begning of the universe. How the Earth comes into the universe
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.
Electricity was not invented, it has existed since the first instant of the Big Bang (if not before).
BANG !
The big bang was the BEGINNING of the universe so there was no temperature before it :P
Our concept of the "big bang" has no explanation about how or why, but our hypothesis is that there was NOTHING before the Big Bang created the universe.
Not the beginning of the universe under the Big Bang theory. The constituent matter of our universe represents a lot more mass than any one Black Hole could contain. However, in a "closed universe", all mass would eventually re-contract into a single location. The presence of a universe-worth of mass could conceivably trigger a process by which the Big Bang would occur again, to spawn yet another universe. Proponents of "alternate dimensions" of existence have suggested that the "death" of one dimension's universe might funnel matter interdimensionally to form the precursor of another dimension's universe. But this is, of course, a hypothesis unsupported by any known physical laws.
