The universe does not need to stop us, because from the inside of it you can never prove you have the faintest idea of the way it is implemented, even if you got to model and understand every single particle and every single interaction. Does an insulated VM run on intel or on powerpc or on a commodore 64 with a hell of a RAM expansion? no way to know from the inside of it.
Pretty sure that with a bit of timing measurement, you could tell apart a C64 from recent Intel. Identifying other, more subtle details of the host might be more difficult, but not impossible.
You're right in that there's no way to actually prove anything about it.
The vast majority of people that bought iPhones bought them because hip and avantgarde and somehow magical.

I snapped almost 500 pics during the early morning hours.
And ruined every single one with a watermark which doesn't even look good, well done.
Today is a good day for information-gathering. Read someone else's mail file.
