Why didn't the big bang make a black hole?

If the universe was super-dense in the seconds after the big bang, why didn't it form a black hole? If it had, the mass that is now the universe would have been unable to escape, as a black hole can overcome even light.

Update:

please give a scientific answer. If god created the universe, that is all good and well, but I am asking this question from a scientific stand point and therefore cannot accept that as an answer. As for the big bang, I think it is pretty well accepted and I want to form my views by that model until it is proven wrong. After all, its the best we have.

Update 2:

if the universe did form a black hole, then it would stay that way, as it could just pack more in, right?

And how could you give something enough energy that it could travel faster than light, which would be needed to escape a black hole. For that matter, if the pre-big bang universe was so dense, shouldn't it have already been a black hole?

Update 3:

oh-

I have read "A breif history of time" actually read it last summer. I didn't recall it answering this question.

    The theory of "big bang" is a consequence of general relativity and Reimannian space where the space and time are related and ependent on each other. In order to have a black hole, you need a certain amount of mass per space volume. The main word here is "per", the ratio! In big bang you have a lot of mass but you also have a lot of space. The entire universe was also shrunk to that spot. So the ratio was not as large as it seems first. The is the reason why universe did not become one giant black hole.

    As to your question regarding the relationship between God and the theory of big bang, one does not disprove the other. Whether there was a big bang or not has no baring as to Who created it.

    If the Big Bang theory is in fact true where did it originate? (I know don’t answer a question with another question.)

    Now at the center of our galaxy (the Milky Way) there is an unusual grouping, cluster or cloud…unknown. Some learned people have said that the area may be a black hole.

    Considering that we know so little about black holes, maybe the big bang (which is just a theory) was the result of a giant black hole.

    It is said that eventually all matter in the universe will start to return, start moving towards its center. Will it just go over and over again?

    Following this discussion, what is on the other side of a black hole? Is there another side? Logically it would have to be a dot, but unless it is a hole in space (which it could be) the matter that it consumes will some day have to be expelled?

    I know this is all philosophical, but I would sure like to hear form you on this. Everything on the subject at this level is merely supposition…but it is interesting.

    the vast Bang and Black Holes are very dissimilar issues. The Friedmann answer for the equations of many times used Relativity, that are the governing answer for the vast Bang, have a uniform density everywhere. The Schwarzschild answer for the equations of many times used relativity, that are the governing answer for Black Holes, have a vacuum everywhere yet at a single factor interior the middle. So, there is no effortless thank you to tutor Black Holes into vast Bangs or vice versa, and there is no at the instant manageable thought of cosmology that exhibits this variety of factor. the vast Bang in all likelihood did no longer requre any "stuff" to blow up. the finished potential of the Universe is in all likelihood to be 0, with the advantageous potential cancelled by using unfavourable gravitational capacity potential. Black Holes, on the different hand, continually have advantageous potential. there is little question that Black Holes exist---the observations of the binary pulsar are accurately consistent with Einstein's equations interior the shrink of sturdy gravity; this observational confirmation makes it exceedingly no longer likely that the equations for Black Holes are incorrect.

    Who said it didnot. If there was a big bang. note the universe is a big black hole . You look at the sky its black with a few white bright holes. Most likely the formation of the Universe may have been a group of small wirlpool of mass structuring processes. A much different concept of the Big Bang. This is just as valid concept we can just as mathematicdlly be shown similaly in terms of tensors.And a equation of field.Their guess is as good as anyone else!

    they talk of a singularity ,but there may have been trillions of singularities all working in twisting manner forming masses out of their surroundings.

    You can play with mathermatic and make logical deduction out of it. But may not really represent how creation occurred .

    If gravity exists than the universe tends to Unite masses toghether toward a comon center.Now this center continually moves to to the fulcrum which would balance all moving masses in the Universe in an equilibrium stable state. so all orbit and masses hold their shape.

    Ignore all the religious rhetoric. The reasons for the sudden explosions are not necessarily known, but "Big Bang" only refers to the sudden and rapid expansion of the universe - not that it was an infinitely dense mass to begin with. There are some theories that the universe collapsed, nearly collapsed on itself, and the near miss created the swirling effects seen in many galaxies.

    Steven Hawking has books on the history of the universe: "A Brief History of Time" and "A Briefer History of Time" to name a few. They are not as intimidating as one might think coming from one of the greatest scientific minds of quite possibly all time.

    A black hole is dense. Does it mean all dense objects are black holes?

    You have stated that if the pre-big universe was dense and it was a black hole.

    As a matter of fact, I don’t know what big bang is, and what a black hole is.

    I read your statements about big bang and black hole and find a fallacy in it.

    A black hole is dense does not convey that all dense objects must be black holes.

    the universe may actually be viewed as the inside of a black hole. a black hole is an object from which not even light can escape. however, the universe is the totality of all objects; therefore, nothing can leave the universe. this means that not even light can leave the universe. by this definition, the universe is a black hole (albeit one of enormous size and extremely low density).

  • Listen buddy, scientists barely know what the big bang was, it is just a vary sketchy theory as to how the universe was created. Plus, the titanium on my Cleveland Launcher 460 golf club is extremely dense yet it doesn't create a blck hole/

    Inverse energy from a Higgs vector field (or inflation field)caused the mass to push apart. Suggest reading The Inflationary Universe by Alan Guth

    Because the Big Bang was a BIG DUD PLEASE READ:

    Okay, now sit down now, boys and girls - it's story time! Shhhh.... Once upon a time, billions of years ago, there was nothing. Suddenly, magically, the nothing exploded into something. That something is called hydrogen. Can you say "hydrogen?" I knew you could. This hydrogen eventually cooled down enough to condense into solid rock. It was magic rock. Inert and lifeless, but still magical. And then, magically, water formed in the sky above the rock. The waters rained on the rock for, oh, let's say billions of years. Some of the rock broke down into minerals, and these minerals washed into a pool of water.

    Then one day some of these minerals magically formed into a kind of goo in the pool of water. Can you say "goo?" I knew you could. Well do you know what happened then? That's right! The goo magically became ALIVE. So anyway, this bit of magic goo magically found something to eat. Then, magically, it found another bit of magic goo to marry, and they had a whole bunch of magical little goos. Eventually - millions of years later - some of this goo grew up into all the plants and animals in the world around us. If it's alive, it came from that first bit of magic goo! Well, more time went on. Finally some of this goo magically evolved - can you say "evolved?" I knew you could - some of this goo magically evolved upwards and upwards, growing ever more advanced, bigger, stronger, smarter, until it became a kind of magical hairless ape with thumbs.

    And do you know who those apes are? That's right! They're YOU and ME! We are the magic rock apes! And you know what else? Someday we'll evolve enough that we'll become the God we all know doesn't exist. Now take a nap.

    YOU CANT PROVE ANY OF THIS EVER HAPPENED

    ITS NOT SCIENTIFIC; you cant TEST it, OBSERVE it, its not DEMONSTRATABLE, you cant use the SCIENTIFIC METHOD TO PROVE IT, ITS NOT SCIENCE...
