As for surviving such a trip, well, you wouldn't ever get this close to a singularity.

I didn't see any correlations, it just seemed somewhat relevant. Either way, trajectories in SE are completely Euclidean and Kerr interiors would be extremely difficult to implement.

I wonder how much computational power would be needed?  It would be ironic if we'd need quantum computers to model relativity, and by then we'd be onto a workable theory of quantum gravity which would replace relativity at the "singularity" and truly reveal what it was.....and then what would we need to model quantum gravity?

I don't think we can say much about quantum computers now, we're essentially 60s people wondering where computing will go.

Does this guy's simulation take into account the motion of the camera?

Sadly not, though it is still an impressive display. I had never seen a real time renderer of almost any black hole metric you might want, even for negative mass (white hole) with spin.

Doc there was recently a paper published on traversable wormholes that did not require exotic matter- I think you would find it interesting.

Wat, is reverse time flow equivalent to negative mass?  For simulation purposes I mean.
Also I hope you find the above articles of interest on traversable wormholes without exotic matter (especially the more recent one.)
