the Big Bang?

Question

To better understand the theory of the Big Bang, can someone tell me exactly "WHO" but the big bang here? like, who made the big explosion? how did it get here? i mean, it just couldn't happend and how can such a violent explosion make such a pretty world we live in today? how could a big explosion make life? gravity? atoms? and how could the explosion be so perfect that makes the planets revolve around a sun perfectly, and earth and the sun are at perfect distance between ejother so that we wont burn or freeze?.. what are the chances of that? just think of how the human body works, the brain..Its all just to perfect to of happend by an enourmouse explosion... please someone explain to me!

Answer 1

you've got a lot of questions here so i'll pick out the few I can actually answer and explain those....

- the actual explosion of the big bang did not create any stars or planets, it just spead matter out into the universe.

matter is attracted to other matter by gravity. large clouds of dust and gas are called a nebular cloud. this is how you get stars and planets...

this cloud of dust and gas will start to spin as it condenses into the center. the spinning motion flattens the could into a disk shape which is why planets orbit in the way they do. the center of the cloud begins to heat up more and more as more matter is condensed into it. this eventually will get so hot that nuclear fission starts to happen, and now you've got a star. the outer portions of the nebular cloud become planets... they will circle the star in the middle because of gravity, and they'll all be on the same plane because they are formed out of the disk shaped nebular cloud. the fact that the earth and sun are at a "perfect" distance from each other is just dumb luck. if you think about it, all the other planets are either too close (and hot) or too far away (and cold) to support life. the earth is just lucky to be at the right distance to sustain life for the time being. the sun is getting hotter and hotter as it gets older, and within 100 million years or so the earth will be WAY to hot to sustain life. the oceans will boil off and all plant life will die... this didn't all happen overnight - the big bang made this possible, but it's taken 7-8 BILLION years for this all to fall into place for us... and as i said before, this will not last forever.

Answer 2

Take a look at Wikipedia's excellent article on the topic:

http://en.wikipedia.org/wiki/Big_Bang

Incidentally, the idea of the Big Bang in no way disproves God's existence. Indeed, the fact that the universe had an origin a finite amount of time ago can be used to argue for a creator as follows:

(1) Anything which begins to exist has a cause;
(2) The Universe Began to exist;
(3) Thus, the Universe has a cause.

This is called the Kalam cosmological argument. It is mentioned in Lee Strobel's book, "The Case for a Creator," which another respondant mentioned. For more on the argument, check out:

http://en.wikipedia.org/wiki/Kalam_cosmological_argument

Anyway, when the theory was first put forth (before there was much/any observational evidence for it) a lot of opposition came from athiests who thought the idea that the universe was started (instead of always existing) had theological implications. I think that Pope Pius XII even expressed hope that the theory would be proved correct.

For more on the Physics of it, you should consult some of Stephen Hawkings works. Either "A Brief History of Time" and/or "The Universe in a Nutshell" has info on it, check them out.

Answer 3

Right now we do not have a good scientific answer. Since our whole universe was fromed as a result of the Big Bang, everything in our universe could be said to be post-Big Bang or an effect of the Big Bang. Frankly, we don't know what, if anything we can comprehend, exists outside of our universe.

The question, What was there before the Big Bang, is really not a very good question since time as we know it and comprehend it is also a result of the Big Bang. So, technically in our finite universe and comprehension, there is no "before" the Big Bang, since our time did not exist and does not exist outside of our universe.

Could some supernatural being, i.e. God, be the cause of the Big Bang? Quite possible, but unprovable and therefore this idea, and question really, is not a scientific one.

Answer 4

ya this is probably the question of the beginning of the twentieth century...to be specific this question arose well at the time of Aristotle... the answers for this ques is still not clear
this is because there is a statement in physics wish tells that it is not possible to determine the position as well as the momentum of a particle with high accuracy at the "same instant".... that is the basic idea behind quantum mechanics.....

everything now we have as calculated values like constants and what ever values it may be..... nothing is accurate cause it not possible as said by quantum mech....

everything is probability.... things which are highly probable are the things which we are much interested..... and the thing s which u look are the things of higher probability

and NOW comes the final thing it's well know that our universe is many billion years old so it had period of time the probability is very small but it happened right form alpha to gamma

the ans lies only in unification of physics

Answer 5

There was a particle, then more than one, then many....

"Imagine a point-like particle. If we draw a graph which depicts the progress of the particle as time passes by, the particle will draw a line in space-time. This line is called the particle's worldline. Now imagine a similar graph depicting the progress of a string as time passes by; the string (a one-dimensional object - a small line - by itself) will draw a surface (a two-dimensional manifold), known as the worldsheet. The different string modes (representing different particles, such as photon or graviton) are surface waves on this manifold."

..before the bang there was an elegant wave...imagine.


Best wishes,

Answer 6

The question you are asking is the subject of many
inquiries, and there are no definite answers to it.
Your desire to reach a final understanding is
worthy of respect, but totally fruitless because
it is a search for something so far back in time,
and so immense that there is no way to reconstruct
the event in the human mind.

You will not find the answer.

Lots of people will post guesses.

You will be no farther along on your quest for the truth.

Turn the page. Go to a new subject.

Answer 7

"great Bang" is a coined word initially utilized in mockery of the belief. in many respects that's punctiliously incorrect. the great Bang replace into quite a surprising growth of area from some factor that we lack the gadgets to discover, as that's secure against us by skill of the particle horizon wherein count replace into first allowed to handle of power. earlier than that the universe replace into opaque, so there are in easy terms hypothesis to describe what existed until now then.

Answer 8

These are great questions. If you really think about it, it is almost impossible for a big bang to create our universe in such a wonderful and orderly way. I believe that their is a Creator who made everything you see on earth and in the skies.

Answer 9

Watch the science channel. They have lots of very good documentaries on this. Big bangs are still going on out there all the time.

Answer 10

If this is a thinly disguised rhetorical question from a creationist, you already know the answer. If it's a serious scientific question, you probably need to do a little more research than ask in Yahoo to get any kind of idea.
