Knowing everything

  1. Jan 15, 2004 #1
    If hypotheticaly speaking you bult a scaner that could scan an enclosed and secure are and the scaner could scan everything down to the smallest atom couldn't it predict exactoly what will happen and when the reason
    I am posting it here is because the scaner would have to be able to detect the Gaonoes I think they are called that are in the atoms and there are even smaller and exetera but if you could and then expand the area the scan could do to citys states countrys planets you could predict everything and everything that will happen and when it could tell tou when the universe started and ends and everything else like how black wholes work with all the info it would have gathered
    I think that it sucks everytrhing around it in to a submicroscopic level and once all the black wholes combine and there is nothing left to suck in all the super condesed matter would all chemicaly react in one blast thus my BIG BANG THiery

    hope you have some interesting things to say by the way I am 15 yeaaaay

    Gee, that sure is a long sentence. You might consider a period here and there...

    Well, Isaac Newton believed in a 'clock-work' universe which is deterministic. He believed that it was possible to know the future of the universe if one knew the position and the velocity of everything in the universe. He wasn't aware of the implications of Quantum Mechanics, however.

    A fundamental principle of QM is the Heisenberg Uncertainty Principle. Basically, this states that the position and momentum of a particle cannot be simultaneously measured with arbitrarily high precision.

    According to this principle, the more you know about a particles momentum and velocity, the less you can know about where it is.

    Also one of the other fundamental aspects of Quantum Mechanics is once an isolated system has been measured by someone, the wavefunction describing all the states collapses to that corresponding to the state that has been measured. A short time after this the wavefunction is then restored to its earlier format making any predictions of properties later on mere probabilities of all possible outcomes. Thus, the original measurement becomes obsolete for the purpose of predicting future properties.
