String fusion during the begining of our universe?

  1. Aug 10, 2008 #1
    Based on the idea that when matter is compressed and heated things tend to fuse and go to a “simpler state” the idea is that if one were to compress and heat the very constituents of matter (strings) to a level to which they all fuse. If one were to compress strings to a level in which their very vibrational properties were inhibited then would it be possible that the strings would actually meld together and become something of a unified matter form. I suppose this would be something akin to a perfect fluid much as what was discovered by Brookhaven National Laboratories at the Relativistic Heavy Ion Collider. It can’t be so that something like a neutron star which exhibits a degenerate state of matter is the most compact that matter can be. If all the matter in our known universe were to be compressed, much like that of right before the bang occurred in the big bang then everything would have to be at unimaginable pressure and thus heat would be at that same level, fusing everything together. This would effectively unify the known forces into one super force.

    From this I wonder what form is it that these melded strings would take on? Would there be any possibility for a vibration from there at this temperature or even at higher temperatures?

    That is a great idea. What is the process was cascading what if the bing bang was not the big bang at all but the big reaction. Much in the same way a star fusion can sustain its self once it gets going. Once the beginning singularity before the big bang reached a certain point all that energy began to condense and compact into matter. This could be one of the reasons that so much energy is stored in matter. In a sense all matter is, is condensed energy.

    That idea somewhat follows a concept known as the eternal inflationary universe whereby the universe is said to be an infinite thing not something that technically has a beginning nor an end but a continuation of what was before. Of course this does beg the question to where did this begin which is a major flaw, I think, of this idea.

    But anyway the singularity you speak of is but a starting point where enough energy from the previous system has coalesced to begin forming a new region or bubble of space. This is all a reaction as the bubble follows a very entropic principle from a small singular system to a growing system fed by the initial amount of matter and energy which it started with. The more energy/matter the system had to begin with the larger it can grow. If there is a lack of matter then the system will grow but then slowly shrink as energy used is dispersed, soon to be overshadowed by regions surrounding it with more energy, most likely being swallowed up.

    If the singularity is a reaction as you say what state were things in before things coalesced? Do you propose it was a pure energy system where only the purest forms of matter resided? I can't even imagine what the energy levels must've been (something greater than 10^23 GeV) and let alone the temperature scale would be greater than we can calculate.

    wouldn't that super condensed strings/matter be the same as the singularity at the center of a black hole?

    I suppose it might be similar in a theoretical sense, but then again we do not have an exact dimension as to what the size of the singularity of the black hole might be, ideas yes but nothing concrete.

    The idea though that the size of the singularity that the initial inflation started from that we have observed was smaller than an atom makes me think that a much higher energy and temperature must have been present and must be present in order to fuse strings together. I would think that this energy/temperature would be higher than what a singularity of a black hole would be. If black hole singularity's had similar energy levels involved than any fluctuation greater than a few degrees would cause massive outward expansion via the Higgs Field like what has been postulated for theories of our inflationary expansion and that means a black hole system would inflate to 10^30 times larger in essence making another bang to the big bang.
