Can you be more specific? What parts of the "hot big bang, cold dark matter, accelerating expansion, geometrically flat, ~14 billion years old" model will be shown to be "deeply wrong"? Do you think that discovering, say, the nature of dark energy, is going to demonstrate that the universe isn't really expanding? That we are going to discover that the universe is really 100 billion years old? That the universe was actually colder and larger in the past?
