Folks usually point out that tidal forces make questions like the one I am asking below hypothetical at best, I understand that.
I am taking as an axiom that a free-falling observer observes nothing unusual when crossing an event horizon. More strongly, the free-falling observer cannot detect in any way that they have crossed an event horizon. If this isn't true, perhaps the reason why it isn't true answers my question.
From this lack of consequence to crossing an EH does it follow that as far as the free-falling observer is concerned, they haven't crossed any EH? How would they know that the singularity has now become an inevitable event for them? For a human observer curious to know if they crossed an EH, what consequence could they check for?
