could the big bang be heard?

No...there needs to be a medium for sound to travel through, considering the Big Bang was the beginning, there would be no 'ether' for any sound waves. Just as we cannot hear any of the large energy bursts from the sun which occur everyday.

i think that what the bible says goes. the bible doesn't mention the "big bang" so i don't think that it happened.

It could be possible but there is something called the cosmological principle that are a set of assumptions about the universe that prevents us from determining that.  Basically we need to assume, among other things, that the laws of physics, as they apply here, work the same in other parts of the universe.  Without this assumption we couldn't make any statements about the universe since it would be pure speculation.

um     you can wonder a lot of crazy things about the universe when one takes the big bang into consideration...\nsay, one might imagine that all the matter that is us and our cosmos, was once one tiny particle- could it remain entangled?

Yup - its the Big Bang alright. But I think i wwill agree with Stephen Hawking on this one .. Whilst God is not necessary to explain the Big Bang, all the theories break down prior to the first fraction of a second. I guess until with have the GUT (Grand Unified Theory) we cannot reject the idea of a higher power kciking it all off.\n\nI will ask this though.. if it was a creator or an Energy (that was already there) - Who created the creator?\n\nIan

It's the whispers from the big bang.

About 15 billion years ago a tremendous explosion started the expansion of the universe. This explosion is known as the Big Bang. At the point of this event all of the matter and energy of space was contained at one point. What exisisted prior to this event is completely unknown and is a matter of pure speculation. This occurance was not a conventional explosion but rather an event filling all of space with all of the particles of the embryonic universe rushing away from each other. The Big Bang actually consisted of an explosion of space within itself unlike an explosion of a bomb were fragments are thrown outward. The galaxies were not all clumped together, but rather the Big Bang lay the foundations for the universe. \n\nHowever, I do not believe in this theory. I believe God created heaven and the planets. Isnt it better to believe this than not. :) I want to leave this Earth a believer. A believer in God and Jesus Christ, who saved us all. Ask Jesus to come into your heart. Accept him as your Lord and Savior.

Sound waves are energy waves that propagate through some medium that can be compressed or rarefied like the air we breath.\n\nIt's theorized that around 180,000 to 700,000 K years after the big bang compression waves (sound) moved through the plasma and hydrogen and pushed matter together and formed the early structure of our universe. During this time period, the theory says that the plasma and hydrogen that was left after the big bang was considerably denser than our atmosphere. The WMAP satellite supports the theory.

In physical cosmology, the Big Bang is the scientific theory that the universe emerged from a tremendously dense and hot state about 13.7 billion years ago

You could start with the Wikipedia entry for the Big Bang.

I don't believe so.  If there is any merit to the Big Bang theory (and there's lots of scientific evidence in support of it), then the universe has a radius of currently about 14 billion light-years, and is expanding.  \n\nThat's pretty big, but it's not infinite.

There is hard, physical evidence that the Big Bang happened. There is NO hard, physical evidence that the god of the Bible existed, exists, or will ever exist.\n\nBUT..! Belief in a supreme being of some kind is a logical belief that can exist right along with the Big Bang. Most physicists and cosmologists agree that there are no physical (as in physics)constraints that can disallow a Big Bang. Something from nothing happens constantly in the vacuum of space!!!!! At sizes smaller than a proton, so-called virtual particles pop into existence all the time. Quantum physics has shown that at these infinitesimal sizes immense amounts of energy exist which can easily "produce" new matter from nothing. The bottom line is that these physical laws exist, and the next question any reasonable person would ask is who or what made these laws, the same physical rules that make a Big Bang possible?

The big bang is the creation of the universe. Scientists have recorded an echo in space, it is the echo of the big bang.

Just one doubt about your  theory,how do you know that only one big bang has taken place as you say that a second one is coming up???And tell me how you would accelerate something to the speed of light as the mass would become infinite.\nAnd according to your theory the total energy in the universe will go on increasing.You are stuck in a viscious circle!!!

The discovery of  the universe expansion(doppler red shifted spectrum lines) was the source of the Big Bang theory (i think)\n\nBTW: this is a SCIENCE thread, all you Jesus Freak back off!\nthe theory of the Big Bang is compatible with the concept of a god.\nwhat was there before the big bang ..let there be light....BANG.

When the expansion of the big bang had gone on long enough, the temperature cooled enough to where a free electron and proton could hook up to form an atom.  This is also the time when the universe became transparent to radiation, releasing the signal we see as the cosmic microwave background or CMB.
