Tuomio,
Allen Guth, the world's most prominent physicist, developed his inflationary theory some years back to explain some of the conundrums associated with the Big Bang. This was the subject of an article in Discover magazine back in 2002. Guth states that the Big Bang was a singular event (that is, only occurring once) was ludicrous. He also speculated that, since the universe sprang into existence from a point in space one-billionth the size of an electron, that it might be possible for an "advanced civilization" to recreate the conditions.
As I implied in the previous post, life evolves upward. Who are we to say what is possible or impossible, if time does not, indeed begin and end with the present universe.
Recently two cosmologists, whose names escape me, have proposed a theory that suggests that the Big Bang was the result of the interaction of our own universe with a "shadow universe" separated from our own by the distance of a single electron. In other words, a parallel dimension that whose branes, or planes of existence, occasionally touch our own producing titanic explosions of energy that create, or recreate if you will, our universe.
The accelerated expansion of our universe has no effect on the interaction between our universe and the shadow universe. This theory postulates that this cycle of creation is never ending. You can find this article in the February edition of Discover magazine.
As you can see, the only thing permanent about astronomical physics is its impermanence.
