Given the responsum by RSZA that we discussed recently, re: chametz
being battel after all, if the quantity is exceedingly small, like a
loaf of bread falling in the Kineret, and given that some Ovedim found
my analysis thereof (Warning: I never actually read that teshuva - can
anyone tell me which one it is, for a sanity check? Thanks)
convincing, namely, that if such bittul happens, it is not the result
of a lack of ta'am, as that standard is reached much earlier, but
rather that at some point, something becomes so insignificant that it
is no longer perceived, if so, I wonder whether we should apply a
similar reasoning here. Namely...

Is "Reshus hayachid olah ad laraqia" literal, or can flying objects be
so far removed from human experience (astronauts are not being
perceived by the people on the ground), that they are no longer reshut
haya'hid, that, perceptually, they are like ba-raqia'?
