Do you believe in the "Big Bang Theory?" Why or why not?

The Big Bang theory claims that between ten and fifteen billion years ago, the Universe as we know it came into existence when a point of inconceivable density violently exploded and began rapidly expanding at speeds that may have surpassed that of light *, subsequently creating out of the cloud of hydrogen gas the first stars, planets, solar systems, and galaxies. Though many support this theory, there are also many people questioning the process of nothing existing, a sudden, inexplicable rapid expansion of a single point, and the creation of absolutely everything. According to the Big Bang theory, the universe is somewhere between ten and fifteen billion years old, but, based on countless observations, there are stars and galaxies older than the universe - how is that possible? The Big Bang theory is called a "theory" because all theories have the potential to be disproved, and I encourage you to keep this in mind while debating the validity of this popular theory of the creation of our universe.

* Though Einstein's Theory of Relativity prohibits anything within space from traveling at speeds faster than that of light, it does not define the maximum speed at which the fabric of space itself may expand.

    Jun 28 2011: I don't like when people say that the Big Bang was the origin of our universe. That is as far back as our current models have gotten anywhere near predicting so far but the "Origin" part is in a big black box that we don't really know about yet.

      Jun 30 2011: As far as I know, no scientist claim that the Big Bang was the origin of our universe. This model aims to describe the early development of the universe, not how it started or what started it.

      Jun 30 2011: The amount of information that exist in the universe, in comparison, to human made theories, facts, and philosophies proves only we are thinking but still not anywhere near all the answers, yet.

      Big bang is looking in the right direction, it was created with all the data we have in relation to information that relates to about a fraction of a fraction in the universe. The big bang cannot be completely accurate as ONE bang. No.

      This universe is far bigger than that! Multi-bangs! Constant bangs... We do not know, we are still so very primitive when asking such big questions outside of philosophy. Cold hard facts, witnessing the process and what not.

      There is no cut and dry unless you know ALL the facts.

      There is a research done now suggesting black holes could have predated the theory of the big bang. I'm not science literate for astronomy but, it is something to look into.

      Never eliminate the unlikely fully, because it could be "- like" the unlikely.

      Why worry about how it all began anyways? Worry about how it will end!
