Energy Theory Questions

  1. Nov 19, 2006 #1
    Second Law of Thermodynamics, the theory of the loss of engery. But how do we know that the engery does not infact go somewhere after?

    The First Law of Thermodynamics, it says that energy can't be created or destroyed. I understand that energy can not be destroyed..which coinsides with my first question. So my next question is where does the energy come from in the first place?

    I've always wondered this, so could anyone help me out?

    :uhh: :biggrin:

    The second law of thermodynamics is about the loss of order (or increase in entropy), not energy.

    As to where energy came from in the first place, I had always thought that the sum total of all the energy in the universe was zero, once you took into account the (negative) energy of fields and so forth. But this is coming from a very sketchy memory.
