Hi rcglinsk

I'm not very knowledgeable on astrophysics (thats why I read Q & A), but as for why BB is the dominant theory, this is because it is the 'best fit' for the observable phenomena. That doesnt mean its ideal, or that sometime in the future a new theory wont replace it. No-one is saying you have believe it, but it is the "best fit" at this point in time.
