it certainly is.. Especially if you consider that the vast majority of the universe's life (that we know of) will be the age of the Black Holes. These initial ~13-14bn or so will pale into insignificance against the trillions upon trillions of years that black holes will exist. So if it's possible for a universe to exist within a black hole, it's almost a mathematical certainty that we're in one

Have a watch of this cool vid and try (and fail like we all do!) to understand the timescales involved

edit: or there's the holographic principle idea, similar but the not the same as the black hole concept. That it's possible to encode higher dimensions on a lower dimensional surface. So our 3 dimensional spacetime is the projection of a 2 dimensional surface somewhere...

(this idea needs lots more work, but it's cool to think about!)
