Just after the big bang the Universe, which as it is said was the size of pea (which seems an exaggeration), which was uniform in density, started expanding. This expansion is the beginning of evolution which culminated, on Earth, in Darwinian organic evolution which is so elegantly described by Charles Darwin in 1859. Since then millions of evidence, direct and indirect, has accumulated which shows that: i) the expansion of our Universe though erratic and uneven, follows the path of evolution as consistently as ii) the organic evolution which has produced living entities.
If our universe belongs to a multiverse in which many universes are present (some has estimated that 10500 universes are there in the multiverse), then there is a possibility that a universe can, through a wormhole enter the space where previously a universe existed, then it is a bit difficult to understand how our universe started expanding from a pea-size entity. Should we say that the universe which slipped through a wormhole has assumed a size of a pea, which is also a difficult idea to imagine. Nevertheless, as it has been said that if a universe slips through a wormhole it needs an amount of energy equivalent to a universe; and therefore it could be said that the slipped-through universe ifs the size of a pea-hole or is much smaller. In any case the expansion of the universe would need perhaps a tremendous amount of energy before, during expansion, it turns cold. This problem needs a satisfactory solution. Perhaps the universe during expansion uses the so called dark matter to use it for expansion and evolutionary ramifications.
The other problem which confronts us is that why the universe, density wise is so uneven; why there is so much empty space; and why the universe simultaneously expands and contracts at the same time. If, as it is believed that, the universe started expanding 13.7 billion years ago (13.7 x 109), and if as is also assumed that after some 16-20 billion years from now the universe will simply “vanish” from the empty space, then would it crawl into a wormhole or its energy would be utilized for the passage of another universe through this whole.
These apparently almost insurmountable problems (no problem is insurmountable!) eventually would be solved. Perhaps a Newton or an Einstein, with intricate mathematical ingenuity and passionate imagination would be needed.
It seems however that to think of initial ‘matter’ present prior to the Big Bang of the size of a pea is a bit farfetched. Could it be said that that ‘material’ is a mere collection of numbers, a sort of string particles trillion times smaller than an elementary particle, is activated to initiate the Big Bang.
It could perhaps be imagined that the compact universe which passed through the wormhole is an untold ‘amount’ of string particles which gives rise to elementary particles and afterwards the expanding universe. Was there any kind of ‘force’ or ‘push’ which activated this collection of whatever it was.
The rest of the story becomes a bit simple. In that a stupendous amount of interaction, fusion and fission brought about the universe which at the present moment is out there. And hence the evolution of the universe which is uneven and haphazard looking.
The one almost unsolvable problem remains; which is that what happens to the multiverse in its totality when such transformation ensues. Does it create a large disturbance throughout the multiverse or it is merely a small ripple in the ocean. It would be better for us to imagine the second scenario. For it seems that multiverse is an almost infinite in its scope and dimension.
The question which can only be answered by looking at the collection of string particles to decipher and decide how the initiation process started. Aristotle was of the view that the Cause of all causes – which we could call anthropomorphically as the God – initiated the creative process. He also theorizes that God turned unconcerned with the emerging universe. However this proposition leads us to ask a rather childish question: what caused the Cause of all causes?
