An Out Of The Box Consideration Of The Universe
Firstly, I am not a scientist, or a mathematician. What I propose here is not a theory, perhaps not even a hypothesis in the eyes of certain individuals. It is simply an idea. Perhaps, in fact it is likely, that it holds no water scientifically, if so, then fine, but at least I put it out there for thought.
Having read some posts from scientists in response to laymen's questions, I am disappointed and annoyed by the negative and pompous response often given. To these individuals, it appears that if one cannot supply evidence, generally in the form of scientific formulae, then your idea should be classified under the heading "fairy tale". If such was the case, then surely this prohibits free, abstract and hopefully unique thought. I cannot believe that all scientific discoveries or beliefs were derived initially from mathematics, there was, surely, abstract consideration first. Are we mere mortals not allowed a platform to air reasonable hypotheses without fear of certain scientific xenophobes venting their spleen at what they see as intrusion into their domain.
I doubt my ideas are unique, but they are to me. I can however, find nothing along similar lines, but then I am not a scientist and am probably looking in the wrong places.
The catalyst for my ideas came recently when I learned that there are (probably) galaxies beyond the visible limit of our universe and that their speed of travel away from us, when added to the expansion rate of space means that in relation to us they are travelling faster than the speed of light. It is believed that each unseeable galaxy originated,as did everything else with the Big Bang. This got me interested and thinking in a broader sense so here are my thoughts:
The Universe:
Let's think outside of the box for a moment..
We know that space is expanding, but we have no idea what it actually is. We can observe and measure the expansion, but it reveals absolutely nothing of what it is. However It stands to reason that if space can be expanded, it can also be contracted - in fact it would seem that the space within the singularity was indeed compressed - hugely. So what is it expanding into? Nothing, I hear you say, the "edge of space" is the edge of everything, there is no beyond, because there is nothing - space just is! Suppose for one minute that there is something beyond this "edge" - oh oh crackpot theory time - you say, bear with me - suppose beyond our accelerating, expanding space there is ... more space. Let us just assume for the moment that the universe is larger than we currently "think".. Perhaps much larger, maybe infinite. Let's call it the Mega universe. Perhaps in the Mega universe, but within the neighbourhood of "our" universe there is a region that is rarefied, stretched, "low pressure" space that is now being expanded into by our own, accelerating, expanding, compressed, "high pressure" space. Nature abhors any void (not just a vacuum), couldn't, no shouldn't this principle apply to space too? Will one day, trillions of years hence, local stabilisation occur as "pressures" equalise?
This gives many interesting thoughts:
Could Dark Energy be nothing more than the energy created by the differing pressure potentials within the Mega universe? Thus it may have been the cause of the Big Bang itself as the potential energy difference exceeded that of gravity within the singularity.
Perhaps the singularity was the cause for the local low pressure - if the mega universe (or at least a part of it) was expanding, the huge gravitational mass of "our" universe held the singularity together creating a low pressure around it. As the outer expansion continued, local pressure would reduce (or stretching would increase, if you prefer) creating greater and greater stress on the singularity, until ultimately the Big Bang occurred.
Perhaps the mega universe is full of space turbulence, a four dimensional swamp of moving low and high pressures - perhaps it was a high pressure that caused a Big Crunch amongst our "own" universe's mass.
Thank you for taking the time to read this. I hope it's not drivel. Constructive thoughts please. Snobby scientists can go away, helpful ones welcome to shoot me down gently.
