Would explain the porosity

Hi SDF

Probes or abandoned habitats would be hard to distinguish from natural objects after a few billennia of impacts, especially since density is no help at all on distinguishing between the options. We might have to land on a few hundred thousand asetroids before we can be sure we've never been visited.

BTW SDF are you "Gary" by another name???
