How did the Universe begin?

Answer 1

In the first moments, the universe was infinitely dense, unimaginably hot, and contained pure energy. but witnin a tiny fraction of a second, vast numbers of fundamental particles had appeared, created out of energy as the universe cooled. within a few hundred thousand years, these particles had combined to form the first atoms.
the big bang not an explosion of space but an expansion of space and it happened every where. no one knows what happened in the first instant after the big bang, known as the PLANCK ERA, but at the end of this period, they believe that gravity split from the forces of nature, followed by a strong nuclear force. many believed this event triggered INFLATION a short but rapid expansion. if infation did occur, it helps to explain why the universe seems so smooth and flat. during inflation, a fantastic amount of mass-energy came into existance, in tandem with an equal but negative amount of gravitational energy, by the end of inflation, matter had bequn to appear.

Answer 2

Well the theory goes ,in the beginning all matter in the universe existed in a single location in space, An immense blackhole, with all matter in space collapsed into something the size of a football. Physicists will usually say anything before the Big Bang is irrelevant because at this point in the equation time=0. It doesn't attempt to answer before this point, because at that point your asking "how did this matter get created." Its a headbanger of a question.
Of course to us it does matter but for science purposes everything in the universe begins at the explosion called the big band. When this singular ball under unimaginable force exploded.
Now according to the maths this event should have cancelled itself out, as opposing particles annihalted each other. Luckily for us there was an imbalance and matter overcame antimatter. The reason scientists believe in the big bang is that this massive explosion caused particles to annihalate each other , to slow , to gain and lose energy and the subsequent release of energy as this occured gave rise to a variety of waves infrared, gamma, and microwave. The one they can detect across the universe even today is the microwave radiation from that explosion which they estimate at 15 billions years ago.
I can accept the big bang, but I also look at the fact that, all the forces do serve a massively important service in keep us from a chaotic universe. The weak and strong nuclear forces bond the atoms that make up our universe, the electric forces hold atoms together in a variety of bonds, gravity holds our universe and solar system together and keeps us stuck to the earth. It shouldn't be put in challenge to a creationist God there's enough evidence to believe both.
When you turn on you TV and you get that static signal a small part of it is actually from background microwave radiation.

Answer 3

We keep answering this question. I dealt with it yesterday have a look through my recent answers and you will find it.

Its okay I have dug it out for you:-

Nobody knows and I mean nobody. As humans we have to believe that something created it all because our brains are not good enough to conceive any other solution. The big bang is a theory based on what we observe in the universe which shows the galaxies are moving a\way from each other in every direction at an enormous rate. To our minds that suggests that if we reverse the process by a calculation some billions of years ago everything was in one place ( a singularity) and the only way they could all move as they do is by an explosion. That could be wrong maybe the cosmos is pulsating. Who knows certainly not the church

Answer 4

Well,we can concede that we and the universe are here.
It is also likely we and the universe did not exist at one time.
So,what preceded us and it?
We can get an idea where we started because the universe was here 4.5 billion years before us.
But what was before that?
There had to be nothing.
The nothing had to have two components to it.
It had to have a potential and the potential had to be finite.
The finiteness allowed it to begin.
A single space-time pulse of minimum size and duration was initiated.
This quantum pulse contained everything needed for a universe like our to evolve.

Answer 5

no one knows really becuase science proves things but religion can't really dissprove or prove anything but religion can question science and sometimes science can't answer the questions.

like science can kind of prove that the world started off with a big bang and that pressure of certain gasses cuased the bang. But then that's when religion steps in and says but what made the gasses and that's kinda a question science might not be able to answer cept for god

Answer 6

There is no proof that the big bang happened, just as there is no proof that a god made the universe in just 6 days (taking rest on the 7th) However, in my opinion the big bang theory is more probable.

Answer 7

there is no proof of it. only theories have been formulated. the one that explains it the best is the Big Bang Theory. it says that all the universe formed out of a blast. the blast made the only particle to split into numerous pieces. these pieces(nebulae) moved away from each other and later formed various galaxies. according to the theory the galaxies keep moving away from each other at a speed greater than that of even Light!!

Answer 8

The unvierse begin when there was a small hot ball, smaller than the molecule which contains all the celestial bodies or heavenly bodies like the planets, stars, galaxies and nebula..

Answer 9

God created the Big Bang. Ta Da you have the building blocks of a model Universe.

Answer 10

Some physicists suggest it was a random quantum fluctuation. Whatever it was, it was the mother of all events. I prefer to believe the Big Bang was an act of creation by a higher Being.
