Dear Paul,
Bold alternative ideas in your essay. Yes, in the basis of physics and knowledge in general, including about the Universe, alternative views are needed. Philosophy is a good helper here.
It's good to recall the philosophical testament of John Archibald Wheeler: "To my mind there must be, at the bottom of it all, not an equation, but an utterly simple idea. And to me that idea, when we discover it, will be so compelling, so inevitable, that we will say to one another, 'Oh, how beautiful. How could it have been otherwise?' "(JA Wheeler, interview with Timothy Ferris, Coming of Age in the Milky Way)
Best regards,
Vladimir
