Can anyone tell me some alternative theories to the big bang? (NOT "God made it"). Alternative scientific theories, and maybe some links to their wikipedia pages. Thanks

I know the big bang is most widely accepted I wanna know the more obscure alternative theories

The 'Bid Bang' theory is the only one (at the moment) that is widely accepted. The measurements that have been obtained with the most cutting edge instruments we have at our disposal all point to the reasonability of the 'Big Bang'.

A theory is just a tool (hypotheses with equations). A theory is either more useful or less useful (than another theory) in explaining what we see.

So far, the Big Bang is the best explanation for the universe as we see it. Still, there are a few problems.

Also, scientists are always looking for better theories, even if they have a good one.

String theories describe the universe in a different manner than do the assumptions used in the Big Bang. Recently, most versions of stirng theories have been unified under the "M-theory".

String theories call for a universe with lots of dimensions (up to 11, the last time I looked), with many of these "curled up" (they have not expanded and they are not participating in the expansion of the universe that we see in the three spatial dimensions that we are used to).

Don't discard them too fast, the curled up dimensions do explain a few things just as well as Relativity.

In some versions, our 3-D portion of the universe is a sub-space of the 11 dimensions (or less, or more, depending) of the whole universe. Because a non-rigid, evolving sub-space in our familiar 3-D world would form a membrane, the sub-spaces of the 11-D universe are called 'branes (or simply membranes).

According to some theorist who work with these theories, the energy that caused the expansion that we are now witnessing came from the collision between two membranes (some 13.7 billion years ago). This approach removes the need for the infinite density and temperature of the original singularity at the origin of the Big Bang model.

However, they too (the versions of string theories) have other problems. Most cosmologists still prefer the Big Bang theory... for now.

There are no other theories. Before the big bang theory, the theory was that the universe was just always there. But since it was discovered that the universe was moving, more importantly expanding, scientist knew that it couldn't be a steady state universe that is static, infinite and was always there. All the galaxies in the universe are moving away from each other which means if you "rewind" time then all the galaxies will be moving towards each other. Eventually all the galaxies would be mashed together and push into a point smaller then an atom, this point is called a singularity. It's this singularity that must of exploded and created the universe, this would explain the universe expanding. Most scientist accept this theory.

there are a bunch of "alternative" "theories" however in science a theory is as close to fact as you can get, so the other "theroies" are really just speculations and have no scientific merit...the big bang theory on the otherhand has an enourmous amount of evidence "proving" its validity. im sure if you type in something along the lines of "how the universe began" you might find what your looking for. as far as those ideas being scientific...i highly doubt you will find anything other than the big bang!!! good luck, i hope this helps!!!

Didn't I see this question posted yesterday? If it wasn't you, check out the web pages on "electric universe". There was a book by that name about 30 years ago. I don't think the scientific establishment ever noticed it, possibly for good reason, but it didn't sound particularly weird. I confess that while I can usually detect complete nutcakes, the mathematics and physics of what constitutes a good theory in physics are quite beyond me.

Before the BB theory, steady-state theory of the universe was accepted.Since it could not account for the microwave background, and since the MB is taken as a proof for the BB theory, it is widely accepted now. But still there are several questions, still unanswered. for example, where was all the matter and energy of the present universe before it was physically born? If before the BB, it was zero mass and only temperature, then it amounts to saying that the universe existed before it was born.

The big bang theory has nothing to do with the origin of the universe. It is completely mum on what may have gone on before it.

one of them is that the Universe has always been here and always will be here
