LOTS OF BIG BANGS.

LOTS OF BIG BANGS. My first post on this blog was about how “radiation from the Big Bang still affects our radio reception.” I have since posted several times about what cosmologists are saying about the Big Bang, including this post about the difficulties of trying to “think about probabilities in an infinite universe in which everything that can occur, does occur, infinitely many times.” I was expressed my mystification in that post. The weekend Wall Street Journal (January 29) had an interview between David Gelernter and the physicist Brian Greene which increased my mystification at the consequences of infinite universes. To begin with, there may have been other big bangs at other locations, each of which created a universe. Greene describes a theory in which there are universes that are identical to our universe, “moment-to-moment.” Greene says: “in an infinite expanse of space, particle arrangements must repeat too—there just aren’t enough different particle configurations to go around. And if the particles in a given region of space the size of ours are arranged identically to how they are arranged here, then reality in that region will be identical to reality here.” And there might be some slight variations. Greene gives the example of the Jets playing the Bears in one of the alternative universes.
