I wonder how many generations of universes there have been. I have no trouble with the idea that there have been an infinite number of universes before ours and there will continue to be an infinite number in the future. I mean, why not?Also, life has arisen from them countless times. Kind of cool to contemplate.
Sure.
Take a look at current trends of thought in physics, and you'll see some really weird stuff--like stuff doesn't really exist until you look at it, observer and observed are the same thing, etc.
I like to think that things never stop "existing." So whatever "has been", still "is.". All at the same time.
