It leaves me wondering, is that data fundamentally impossible to collect, or do we just not know how yet? Sure, maybe the problem is unsolvable by math alone but that doesn't make it mathematically unsolvable. Maybe we could build or capture a black hole in the lab, put detectors all around it, and watch it evaporate, or something.

They did this in Earth by David Brin.

Some theorize that evaporating micro black holes could/should be an observable effect of the Large Hadron Collider. https://en.wikipedia.org/wiki/Micro_black_hole

It might not really be fundamentally impossible, but it could be completely unachievable practically - harder than unscrambling an omelette back into an intact, uncooked egg.
