Multiverse ?!?!?!

When one looks at the big bang cosmology, it looks like a perfect recipe for a universe to be formed; exactly placed between the extremes of an immediate gravitational collapse without allowing the universe to evolve OR being thrown apart before any structure formation took place. How did this happen? Who fine tuned the constants? Or did somebody??? anthropic principle??
Do we live in a multiverse where universes are continuosly being born and dying like the bubbles of water? and among them one in a few millions (?) or so comes out with a perfect recipe for evolution of structure and subsequently life? And we live in one such superhit universe?
How about having a peep into other flop universes?? Excuse me, Any worm holes there???? I wanna trek to a flopverse but dont have any exotic matter currency, Can I have a ride please....
