I can try to tackle this I do think and meditate on it quite a bit. Ok since I believe that the 3rd dimension or the physical universe is only one of many parts that make up the whole (god). the physical universe in my opinion did have a start and may have an end, allthough time is a funny thing for us, for the creator the entire 3rd dimension could be like a cd rom that (shim) can plug into any point that shim wants to so it could have a beginning and an end but that is not certain.
The big bang in my estimates was very real, actually I think there may be more than one universes in existance in the 3rd dimension possible millions or trillions. The universe is expanding, that is basically a known fact, I am partly into astrology and they have basically measured how fast the universe is expanding. If it is expanding, then it must have been closer together all the way back to where everything is lumped into one solid mass.
Ok so earth was created quite randomly, watch the discovery channel some time, they have specials on the creation of stars and planets all the time. Basically shortly after the big bang, heavy clumps of gas and matter began drawing other clumps into them, at that point the basic elements of the universe were probably hydrogen and a few other basic atomic structures. When these clumps got so massive that they imploded, the force of the implosion set off a hydrogen bombe only it was with the raw materials of roughly ten times the sun, this created a supernova. (I think) The supernova created other elements in its forge, thus creating most of the elements and maby others we do not know of. When clumps again started to form, with sufficient hydrogen and other elements solar systems began to form and suns began to burn.
The creation of a solar system is much more detailed than that but from memory that is all I can come up with for now, you will have to research it if you are interested.
The start of everything, that is a different story. When did it happen? Now, I mean time is only a 3rd dimensional idea, movement from Point a to point b takes x where x is time. other dimensions operate entirely different. I don't know if any of you watch andromeda. One episode they jump into another dimension and in that dimension what you think becomes your reality. if you think about going to a place you will go there, if you think about something you want or need you will have it. Other dimensions might work this way, no real physical existance, just a pure extension of thought.
ok so how it all got created that was the question. OK shim, God whatever was all that there was, it was perfection, all knowing. One problem, god only knew that which was god for god was all that is. god did not truly understand godself because all that god had ever experienced was being god. Now god is all powerful, pure unbridled power, no limits. So what god did was to divide himself into an infinite amount of entities, then god removed his god knowledge from those entities (by different degrees mind you) then god took other parts of godself and made things for his smaller selfs to experience, he created all sorts of different environments. Really every environment god could think of he made, Which is infinite by the way. then god gave those smaller little god parts a way to interact with those brand new environments. God also made a system where those little god selfs could communicate the experiences they had back up to god, god could also communicate down the ladder if god so chooses. So now god has an infinite number of little god selfs running around in an infinite number of environments, sharing all they experience with god. this is why good and bad exist, god needs to know what bad feels like so god can truly understand what good feels like. if all that was ever felt was good, it would not be good at all it would be quite mundane and boring.
ok i'm taking a break now.
