The big bang theory?

Question

What went BANG, and what was it doing before it went bang, (considering this THEORY is true)

Answer 1

I studied under the late Ukrainian physicist Georgiy Gamov who first postulated the Big Bang. George proposed that the universe emanated from a single infinitesimal point (singularity) in a Big Bang. George speculated that the singularity (1) defined time itself, (2) had always existed, (3) emerged spontaneously, (4) or was the death singularity of a previous universe (perhaps our own universe run in reverse.)

Answer 2

Everything went bang. Everything around you, all the stars in our galaxy and other galaxies, and for many billions of lightyears beyond. It was all highly concentrated and pressurized, and has been expanding outwards ever since.

What was it doing before? That's beyond current physics, but there are speculations. Possibly, it was a very rare quantum fluctuation in an empty space. That space, if it existed, would have been pushed aside by the space inside the Big Bang.

There are no abolute proofs in science. To say that something is a "theory" is to say that it is a proposed mechanism or explanation that has more or less evidence for it. To be a "theory" is the best any scientific idea can do. All theories are subject to doubt and can be overturned or improved. The Big Bang theory has so much detailed evidence for it that its major ideas (expansion of the Universe, evolution of the elements, etc., existence of a horizon) are almost certainly true.

Answer 3

It's really a fairly simple theory that says that since the known universe is expanding, if you do the math backwards, everything must have been compressed into a single point at some time. This resulted in a more concentrated study of smaller and smaller things in a belief that this would reveal the truth.

The same math, at some point, since we know the process, would more likely suggest that our known particular clump of planets, stars, and galaxies could have been created by the collapse and explosion of a really super super big star from another expanding clump of bigger stars and galaxies where the separation is 100s of billions of light years but, they skipped over this point.

There is also the problem of the vacuum which is mostly and widely ignored and usually disavowed while it is becoming more and more apparent. Some have tried to say that light, strings, sound, super vacuums, polarization, waves, and other things existed in a vacuum when we know that there is no such thing in a vacuum and a vacuum does nothing and has no energy until something is put in it.

So, your guess is as good as any at this point but, maybe the truth is not in the smallest thing we can see but in something so large we can't perceive it.

Answer 4

The Fraudulent Gurus have a theory called Sensan Hiday which claims that Matter was brought into being as a result of a single sound. More like the Big Twang than The Big Bang. They've got a lot of other cool ideas about science and religion.

Answer 5

the ting is according to the theory there is a constant change of expansion/compression where for years all matter in the universe spread out (after the big bang) and then in an instant (according to the Big Crunch theory) all matter will immediately contract into a space the size of an atom and remain that way until the next big bang. think about stretching out a rubber band then letting go it stretches as far as it will go before it just comes back to the center a s fast as possible

Answer 6

The universe at the time was compressed into a single point (ie infinate mass but zero size). This was very highly compressed which then expanded rapidly and hotly, much like an explosion (actually, bigger than the biggest exposion you could ever imagine).

Just prior to the bang, the universe was (theoretically) compressing under its own gravity down to the singularity. There is a theory that the universe is constantly expanding and contracting.

Answer 7

My guess would be it went fizz and pop a few trillion times before it finally went bang. A bit like turning over the engine of a car that won't start, until it finally from nowhere finds the right combination of essentials to spring to life (even though they were all there the whole time).

I honestly think it's a complete fluke any of us / this is here at all.

Answer 8

This is where people usually start believing god. Modern science has answered pretty much every question w.r.t. the formation of the universe, including life on earth. What it hasn't yet answered is what was before the big bang. So- for those of you who want to believe in god, here's where you get to say, "I told you so- if you can't answer every question, then god must exist".

This one we may not know for a long time.

Answer 9

Theory is true. But some fine details has to be worked out

Answer 10

my foot went bang through my computer in a vain attempt to re-boot it, after people kept asking impossible answerless questions
