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.
Without the Big Bang there would be NOTHING. The entire Universe - including space, and apparently even time! - is the result of the Big Bang.
If the Big Bang never took place, the universe as we know it would not exist. The universe began as a singularity and expanded rapidly from that point. Without this event, there would be no galaxies, stars, planets, or life as we know it.
well, the big bang is really not true there couldn't be a big bang or else a whole new universe would start again.but....if there was by chance the big bang would happen then it would swallow up all the planets and every thing around it starting a new universe(we would all be dead)
One primary unanswered question about the origin of the universe is what caused the Big Bang to occur. Scientists are still exploring the underlying mechanisms behind the initial singularity that led to the expansion of the universe.
It began to expand in size. There is a hole at that point in our knowledge of the early universe but without a doubt the universe began to expand.
Some questions about the Big Bang theory and its implications for the origin of the universe include: What caused the Big Bang? How did the universe evolve after the Big Bang? What evidence supports the Big Bang theory? What are the implications of the Big Bang for our understanding of the universe's beginning and future?
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 Big Bang Theory tells what happen at the begning of the universe. How the Earth comes into the universe
BANG !
The big bang was the BEGINNING of the universe so there was no temperature before it :P
This is "The theory" which may also explain the acceleration, that is taking place in the universe. Our universe is surrounded by some 4 such universes, probably four pre big bang masses. In turn the four pre big bang masses are surrounded by four universes. Those universes are surrounded again four pre big bang masses. So one universe is surrounded by four pre big bang masses and one pre big bang mass is surrounded by four universes. You can find the structure of carbon atoms in case of diamond to imagine the same. So your universe is getting acceleration due to gravitational forces of the four pre big bang masses and other universes. So there is probably nothing like 'Dark energy", which "Push" the universe. But there are probably four "Pre big bang masses" and other universes, which are "Pulling" your universe from the "Out side" to give acceleration to your universe. It may take another billions of years, for your universe to "Fall", on those pre big bang masses. Once your universe "Fall" on such pre big bang masses, that will initiate "Big bang" there in those pre big bang masses. This theory also explains to why the acceleration in expansion of the universe did not start from the starting of the big bang. The big bang started at the point, where the gravitational force of the outer universes was zero, like Lagrangian points. Once your universe started to expand, it drifted more and more from this zero gravity point. That gave an opportunity to outer pre big bang masses and universes to pull your universe apart, giving it an acceleration.
The Current Generally accepted theory of Ultimate fate of the universe is that it will reach a maximum entropy in a finite amount of time, ie the universe will be uniform having lost all its energy and will have no gradients, this is called the Heat Death of the universe, if this theory is true (And its most probably is) There wont be another Big Bang.
