so, alright, there is no gravity in a vacuum as it doesn't have any mass.
but
if u take an empty plastic(disposable) bottle n pump the air out the gets crumpled , from this i can conclude that as air goes out of the bottle the walls of the bottle crush in to replace air. alright there too
but
the same doesnt happen when u create vacuum inside a bell jar ,i.e. the glass doesnt crush in, as the glass is thicker or denser( or something else, i dont know the correct scientific term)
so, it seems like the vacuum does pull in but only upto some extent
or, alternatively, i can ask y does the plastic bottle walls rush in but the glass doesnt?
