    If there are multiple universes, is it not logical to assume that these universes all have the same origin? And assuming this is true then wouldn't all theses universes have the same Laws of Physics and contain the same elements? They all came from the same place.

    Maybe.

    Maybe, but maybe not, even if the first answer is yes.
    They all came from the same place.
    We don't know that either.

    I have to say that I believe things only work one way. The belief that they may not is used by creationists in saying that god set up the laws originally as though snow could be cold, hot, come in pentagon shapes, fall upwards because it is lighter than air, come in several different colours, etc.

    I have no idea if creationists make such a claim, but if they do, that is hardly evidence of anything one way or the other.

    I guess you never buy a return ticket, then.

    Our universe may be recycled from another, and the end of our one may give rise to a new one. At least this is my vague understanding of Roger Penrose's latest book 'Cycles of Time'. Time is the increase of entropy, or randomness in the system (ie the universe) and is nothing to do with progress.
    If the multiverse exists, then there is no overlap between universes, rather it is the result of endless time cycles.

    If you make a slight change in one law, the whole universe could cease to work. A universe based on different laws would be different in every way, to the point that we could not exist there.

    Assuming there are various Universes (infinite number ?) note that as soon as various variables reac a certain value in the initial expansion (time, energy, location, momentum, etc.) the Heisnberg Uncertainty principle kicks in and all subsequent changes can vary within the range hbar/2pi (sorry don't know how to type that) leading to extremely differing universes.

    Isn't it conceivable that all physical laws are just the effect or realisations of only one or a few more fundamental ones? In this way, it wouldn't be possible to fiddle around with them randomly.

    The physical laws determined by 'early condition' that is given. If multiverse exist, it might have the different laws, just in quantization. It works in the same way as our universe has, but the difference is just in 'constanta'.

    the entire multiverse idea is a way of explaining away the conditions of this universe by expanding the odds

    ishmaelblues. If you have a multiverse, you can say that the material and energy for our universe came from elsewhere, so preserving overall integrity. It does not however explain how the multiverse started off.
