Cosmic Fun: Random Ramblings in Modern Cosmology: Conclusions: Part One

The following ideas are primarily mine alone, the good, the bad and the ugly, albeit based on and influenced by reading multi volumes of tomes in modern cosmology. However, I’m also quite sure that numerous others have quite independently thought somewhat similar, if not exact, thoughts as well. Therefore, I’ll take no credit for being right, if I don’t get blamed for being wrong!

CONCLUSIONS (Part One)

Okay, here are the answers (well, my answers anyway)!

1) Trends: Over the past 2000+ years, three undeniable trends have emerged in our on-going studies of life, the universe and everything. It’s probably worth while keeping these in mind when pondering the cosmos and what future discoveries are likely to reveal.

Firstly, our place in the central scheme of things has gone from be-all-and-end-all uniqueness, the cream of all there is and every will be, to, well, just another life form. Detection of extraterrestrial life, especially extraterrestrial intelligence will be the final straw (nail) in that scenario (coffin).

Secondly, we’ve shrunk over time as well as become displaced. Earth is no longer all there is (the be-all-and-end-all of real estate) and the centre of everything (we’ve been moved from the CBD to the boonies) as well. As our visions of the size of the Universe have ever increased (see #1’s progression above), will there ever be an end to it?

Thirdly, cosmological common sense has decreased, given way to weirdness. Or, depending on POV, weirdness has increased over time in all things cosmological. The well ordered and common sense cosmology of Genesis or the ancient Greeks was pretty straight forward.  Even up through the life and times of Copernicus, Galileo, Kepler, Brahe and Newton that was still pretty much the case, albeit with the invention of the telescope things did get a little weirder (and more unsettling) with respect to Genesis (and the Church) and the ancient Greeks (and other ancient societies like the Chinese). Then, ever accelerating, the weirdness quotient, the scientific fertilizer, really hit the fan! In fairly short order came uncommon sense descriptions of the cosmos and the stuff in it. Concepts like relativity, space-time, quantum mechanics, black holes, wormholes, dark matter, dark energy, antimatter, atomic structure, and string/superstring theory. Nothing made much common sense anymore. I suspect that’s a trend that’s also likely to continue. In fact, you can probably bet on it.

2) Did God or Nature Create the Universe/Multiverse? Here I opt for nature. If God can create one universe, God can create more than one universe (but what would be the point of doing so?).  If nature can create one universe, then nature can create more than one universe. Since nature isn’t intelligent, creation of multi-universes (the Multiverse) is more like to be a natural than a supernatural event. That is, it’s probably illogical to create more than one universe where one will do – so that eliminates the God hypothesis since we assume that a God would be logical. Nature however tends to be prolific. Since nature, that is the laws of physics as we understand them, can adequately explain the creation of a universe(s), there is no need to appeal to a supernatural being or higher authority or universal designer, or whatever.

3) Universe or Multiverse? Here I opt for the Multiverse. But the background to the Multiverse, that which contains the Multiverse, is something I call the “Superverse”. There is, always has been and always will be a super vast expanse (call it the all being “Superverse”) of nothing – that is, the vacuum (lowest possible) energy (state) which seethes with quantum activity and pervades everything. That’s the bottom line. I don’t know how big the Superverse of vacuum energy is, maybe it’s infinite (but cosmologists, physicists and I too like to steer clear of the can-of-worms that is infinity), but when I consider the following progression, logic suggests ‘pretty damn big’. Just as an atomic nucleus is tiny relative to an atom; an atom is tiny relative to you; you are tiny relative to planet Earth; Planet Earth is tiny relative to our solar system; the solar system is tiny relative to the Milky Way Galaxy; our galaxy is tiny relative to the super-cluster of galaxies of which it is a part; our super-cluster of galaxies is tiny relative to the observable universe. That’s as far as knowledge can take us, but if the progression continues, then our observable universe will be tiny relative to our Universe; our Universe is tiny compared to the Multiverse, all of which resides with the Superverse energy vacuum!

To be continued...
