    It is said -the entropy of the Universe is increasing...which means the disorderliness of the Universe goes on increasing. How then ,the bigbang state to more organised Inorganic Universe to Life from simple organism to the evolution of the thinking human...Is not the natural flow to better and better organization?

    You're thinking of what order is in the wrong way.

    The idea of entropy increasing can be thought of more easily as "energy tends to disperse".

    I don't know how true the following is, but I've heard it said that the dispersion of energy is what causes the random mutations that occur during the formation of DNA. Thus it would seem that entropy in fact instigates evolution. Or rather entropy creates options which are then exploited by natural selection.

    Just what I heard... might be wrong...

    Well, for this argument lets assume that the Big Bang actually happened. According to the big bang theory, at the instant of the big bang, all matter and energy occupied a singularity and all forces were one. This was the most ordered the universe could ever possibly be, even more ordered than life, planets etc. So ever since then, looking at it that way, the entropy of the universe has increased over time and things are becoming more and more unordered.

    The dispersion of energy is not what causes random DNA mutations. Mutations are caused by environmental factors such as UV rays, nuclear radiation, viruses etc..

    @Waveman28

    few more questions

    1. What is the pre-BigBang state hypothised as?

    2.Was the universe more orderly say,some ten thousand years earlier,meaning at that time entropy was less than it is now?

    3.Are chaos and entropy inversely proportional to each other.? If so can BigBang be described as chaos?

    Mutation cannot be described as disorderliness,it is just a new pathway.

    Energy dispersion need not necessarily mean more disorderliness,or does it?

    Indeed, what I was suggesting is that the entropy generated during these external processes, ultimately is what leads to the mutations.

    What is the pre-BigBang state hypothised as?
    There is much speculation as to what may have been before the big bang, but keep in mind that none of this has been proven in any way and is nothing more than conjecture. String Theory predicts that there are things called "branes" which exist in higher dimensions which through collisions, caused the big bang.

    In my opinion, all theories which attempt to describe "before the universe" are a waste of time. The universe may not have even begun, it may have just always existed.

    Was the universe more orderly say,some ten thousand years earlier,meaning at that time entropy was less than it is now?
    Yes. In an isolated system, entropy never decreases over time.

    Are chaos and entropy inversely proportional to each other?
    No. Chaos is basically another word for disorder. The relationship is this: as a system becomes more chaotic, its entropy increases.

    If so can BigBang be described as chaos?
    Not really. The big bang is what caused the universe to exist, so you could say ever since the big bang, entropy has been increasing.

    Sorry,I made a silly mistake. I meant to type "directly proportional",instead put in just the opposite.

    Well, universe is just a term to that thing upto which our conjecture can reach.

    But we are still not getting near this entropy and disorderliness.

    I cannot digest that 'just after BIGBang-Universe" was more orderly with its fewer entities than the current universe with its diversity both in the Animate and the Inanimate.
