Rob,
Thanks! And figuring out how those initial conditions came to be and what they are is a question everyone has an equal chance at answering. Academics are more about describing systems like the universe as they already are and not about how those systems came into being in the first place, so they have no advantage on the second topic. What irritates me is when they pontificate about this second topic (e.g., Why is there something rather than nothing?) and other topics outside their area while at the same time deriding amateurs for their ideas on these same topics.
Also, physical laws describe physical things, interactions and changes in the universe. They're not fundamental like the initial conditions and what brought those initial conditions into being. As you say, the initial conditions and how those initial conditions came into being dictate the game.
But, given that, I agree with them that anyone's ideas on these topics should match reality, be testable and be able to make testable predictions.
