Cosmological considerations by a crumbling corpus

┬áCute alliterations aside, I ain’t smoking anything. I just seem to find a wide variety of things rather interesting. I’ve read some of Hawking’s books, need to get around to doing some reading on string theory, and am quite happy to devour the babblings presented on the testosterone channels. Interesting that black holes “leak” – read up on Hawking radiation (believe that’s the right name) – when the common understanding is that nothing can escape a black hole. The devil is always in the details. Another one I like is that the universe is “lumpy”. Apparently, the expectation is that after the “big bang”, the distribution of the background radiation remaining would be fairly even……..but it’s not. There’s thoughts that the universe is not “eternal”, even after the “big bang” created it, that the universe is in fact cyclical – it’s born, dies, is reborn, etc. There’s even an alternative to the big bang – that the universe is actually FIVE-dimensional – the three we know well plus time (the fourth) and another beyond that. This five-demensional universe has some number of “membranes” and what we consider to be “our” universe is the result of the collision of two of these membranes. In the area of galactic formation, the current rage apparently is something called co-evolution. A galaxy and the super massive black hole develop together.

At this point, five-demensional universes are beyond me. I still like the big bang idea myself. It doesn’t seem unusual that the universe would be lumpy. It seems unrealistic to think that the “presence” of the after-effects of the big bang itself would be perfectly uniformly distributed. The whole idea behind the explosions used to implode a building is to NOT let them be uniform, that the energy from a given blast to be directed at a target – say a building pillar. Repeat that with multiple blast and you can control the way the building collapses. So the energy and matter created/resulting from the big bang has clumps as the universe expands. A bigger clump attract a smaller clump and collides forming an even bigger clump. A whole bunch of clumps are the beginnings of a galaxy (galaxies aren’t evenly distributed either). The clumps at the point where the most clumps are eventually is what becomes the core of the galaxy and becomes massive enough that its gravity reaches a point that it becomes so strong that it can capture anything near it, even light – we have a black hole. Remember the time scale we’re talking here. The billions of years that Earth has existed are less than a blink of an eye to that. If the mass of a star or planet create a dimple in the space time continuum, galaxies and clusters of galaxies do too. Given enough time, these clumps will merger with each other bit by bit. There’s a number of examples of galaxies that have collided or are going to. These super massive black holes will merge too. (Imagine how nasty that would have to be keeping in mind that nebulas are the result of a star going nova. Couldn’t we eventually end up with all the matter an energy of the universe being one singularly massive black hole? One that can’t “keep it all together” because it’s “eaten until it busts”. You’ve just had another big bang. When you have eternity, you have one bang after another.

It’s been said that cosmologists are proving the existence of God. Odd thought here, but what if this cycle of big bang sucked backed into a SMBH that explodes in another big bang is actually “God’s heartbeat”????
