There are many theories about the Big Bang, and whether it even occurred ....if you believe some people. The thing is, nobody can say one way or another. For this reason - and the fact I consider it largely irrelevant - I will not dwell on the various hypotheses (a brief personal hypothesis is at the end of this article). However, one theory can safely be dismissed, creationism.
[Creationism is the religious belief that the Universe and life originated "from specific acts of divine creation" For young Earth creationists, this includes a biblical literalistic interpretation of the Genesis creation narrative and the rejection of the scientific theory of evolution]
There is very little doubt the Big Bang occurred and in fairness to creationists, it might have been caused by a superior being. That is not the issue I have. In my opinion it's all a matter of scale, and that is where the creationist hypothesis falls to the ground. Let's say the creationists are correct and the universe was created by a supreme being. In order to facilitate such an achievement, the creator would have to be outside the universe*. Considering what a minute spec we are within this vast universe, communication between us and a creator would be implausible at best.
*if you really want to get goofy you could say the supreme being was within the void which the universe now fills and a whole new series of hypotheses spring to light but at some point you have to draw the line.
Then as planets go, we are pretty small and just one of an incalculable number. The next question would be why the need for communication anyway? In geological terms we have only been on the planet for the blink of an eye. Incidentally, creationists stating the world is only 6,000 years old aren't doing their argument any favours. I'm not sure of the accuracy on dating methods but they're better than creationists suggest!
At this point those of you who think God has discreetly vanished in a puff of logic, don't get your hopes up. He will feature sporadically in future posts, albeit not in the conventional sense. The obvious thing that jumps out at me in the clip above, is the way everything in the universe is in some way connected. This conjures up all sorts of possibilities, but my first goal was to work out why the Big Bang occurred. I had a lot of fun with this.
First off I wondered about this scale thing. What if we were tiny beings within some larger being. What if the universe is a brain and we are merely the figments of an active imagination. Maybe we will dissect a brain one day and find a little universe inside, who knows. If that's a little too whimsical, I had thoughts of the universe being contained within some giant nuclear reactor. Maybe we could reach the edge of the universe one day and find an observation window. There we will see a man in a white coat with a clip-board, totally unaware of our presence. Of course due to scale he would appear to be static. The Big Bang was an explosion after all. Perhaps it was something like this below ....but without the gravity.
It would probably be without the actual bang as well. Sound needs a medium to travel through and there was just the cold dark vacuum of space at the time of the Big Bang. For this reason I somewhat facetiously refer to it as the Big Pfft, hence the post title. The subject is contentious whatever your stance, and of not enough relevance for me to waste time on it. The summary below is a simplistic view of conclusions I drew with minimal* research.
*it was actually quite a lot of research for a layman
In simplistic terms, I broadly follow the Big Crunch theory as the precursor to the Big Bang. In fact I would speculate this happens in cycles. Imagine the universe as a deflated balloon, all the matter is contained within this balloon as it expands. At some point the energy from the Big Bang will peter out and then the 'balloon' will contract until it becomes a singularity and the process starts all over again.
A lot is made of dark matter and black holes but I believe this to be a natural by-product of matter passing through a void at great speed. Why can't dark matter simply be nothing? Scientists suggest it has a mass due to anomalies in stellar motion but I think it is something far more simple. Black holes are vortices caused by disturbances in the void as matter hurtled past. They in turn draw in other matter and galaxies are formed. Due to the vast emptiness of space some of these 'holes' may travel vast differences before sucking matter into their gravitational influence. Gamma rays are expelled as matter is sucked into the vortex and compacts to create such energy. There is much more to this hypothesis but as stated there is little relevance for the purpose of this blog.
