I’ve read a bunch of post about how the universe does not exist inside, nor is, a black-hole.(adsbygoogle = window.adsbygoogle || []).push({});

Still, for my question I would like to assume the universe exists within an event horizon (actually highly curved space-time, that locally, appears flat), and has a massive singularity at the “central” event (in the inevitable future). (With this additional specificity I’m trying, probably unsuccessfully, to get around the arguments listed in this faq: https://www.physicsforums.com/showthread.php?t=506992 [Broken])

Considering that the radial dimension (“distance” to central-singularity) may indeed be our time dimension (as we free-fall towards the central event, we experience the passage of time), this makes me ask a few obvious questions, but I can’t seem to find the answers out there.

Would radial (time dimension) tidal forces fit with the measured accelerated expansion of the universe, a.k.a dark energy? (In other words, is the central singularity, which would be the source of dark energy, rather than pulling the universe apart in space, is pulling it apart in time?)

Would longitudinal (spatial) tidal forces fit with dark-matter measurements? (object’s close to each other, appear to get pulled towards each other as they fall towards the singularity which is directly between them spatially, but in the future.)

Would spaghettification fit with/account for the “smoothness” we observe in the distribution of energy and matter in the universe?

Would the mathematical description of the event horizon (possibly as a 3-brane), as experienced locally, fit with the mathematical models of the big bang?
