Matter with different constants

  1. Apr 2, 2008 #1
    If the physical constants vary from universe to universe in a multiverse, then if matter from this universe were to somehow go into another universe, say through a wormhole, what would happen to it? Would it disintegrate, or somehow behave strangely? What if the
    cosmological constant varied in the other universe?

    I suspect that space and matter arise from the same fundamental constituents----that is, geomety and matter are emergent, and have the same underlying dynamics and degrees of freedom.

    in that case the properties of matter are intrinsic in any volume of space-----the constants you mention are built in to space itself.

    in that case matter cannot carry its properties or constants with it and travel thru a tunnel to some domain with different matter. the bridge would have to be made of space, and whose constants would the space have?

    In some exotic inflation scenarios there are "domain walls" dividing domains with different physics (different constants, laws perhaps) which travel at the speed of light and which are LETHAL. If a domain wall passes thru your galaxy, you've had it. AFAIK such exotic inflation scenarios do not have much justification and are mostly just piquant fantasy.
    ======================

    The above is just my own take on it, you asked a speculative question. but the basic problem is that no one so far has offered any scientific justification for assuming that a "multiverse" exists. That is, there is no scientific reason to think that the universe consists of domains with different laws or different physical constants.

    People toy with the idea if it appeals to their imaginations. But do you know any justification for it? If so, please tell us!

    Then what is the probability that another universe has the same constants and laws as ours?

    I see no justification for assuming that a different universe exists, therefore the question of probability doesn't mean anything to me.

    Do you understand what I am saying? If there is no other universe then what probability are you asking about?
