  Analogue experiments have attracted interest for their potential to shed
light on inaccessible domains. For instance, `dumb holes' in fluids and
Bose-Einstein condensates, as analogues of black holes, have been promoted as
means of confirming the existence of Hawking radiation in real black holes. We
compare analogue experiments with other cases of experiment and simulation in
physics. We argue---contra recent claims in the philosophical literature---that
analogue experiments are not capable of confirming the existence of particular
phenomena in inaccessible target systems. As they must assume the physical
adequacy of the modelling framework used to describe the inaccessible target
system, arguments to the conclusion that analogue experiments can yield
confirmation for phenomena in those target systems, such as Hawking radiation
in black holes, beg the question.
