Film technology resembles buckets for collecting light in.. basically no way whatsoever.
Changing the ISO of the sensor does not change the physical characteristics of the bucket that is collection light, it does change the effective electrical characteristics, to the point that the bucket "becomes full" sooner. You may choose to view this as "the bucket does not changes size, but we're putting bigger photons in it" or whatever else you like. I happen to think that a bucket which fills up faster is usefully considered as "smaller".
EDIT: why are you picking at miniscule trivialities like this? "you didn't invent it" and "the buckets don't REALLY get smaller" are you in sixth grade or something?
