I have been reflecting on the idea that our universe could be the interior of a giant black hole, but several fundamental questions arise. How can this account for the apparent flatness of the universe, given that a black hole’s interior should exhibit strong curvature? Observations indicate that our universe is nearly flat, yet this hypothesis lacks a clear mechanism to explain why. If we are inside a black hole, where is the boundary? A black hole's internal space-time is inherently limited by the event horizon, yet our observable universe does not show any indication of such a constraint. How does this model reconcile the absence of an observable edge? Furthermore, in classical black hole physics, the event horizon expands only when additional mass or energy is absorbed. In contrast, our universe’s observable horizon grows over time without any apparent external input. What mechanism would drive this expansion in a black hole framework? These points suggest that such a model would require an unconventional and exotic space-time structure beyond classical general relativity. I would appreciate any insights on how these issues could be addressed. Quentin All those moments will be lost in time, like tears in rain. (Roy Batty/Rutger Hauer) When you refer to the horizon expanding of the observable universe, are you now assuming the universe is expanding spatially, rather than just the average galactic distances increasing? BTW, I'm confused about how that horizon increases spatially. Aren't the galaxies in the unobservable regions receding faster than light speed, and this is the reason they're unobservable for us? If so, how can the observable region increase so some of them become part of the observable region? One other thing; I viewed a video showing BH's releasing material when too much is inflowing. Is some of this material from the interior, or is all of it inflowing material that is rejected?
