I agree.  But the term 'zero gravity' really refers to 'no apparent gravity',
at least, not apparent to our gross physical senses.  It is in the same class
as 'centrifugal force'.  There is really no such thing, but you would have
a tough time convincing someone who had experianced it.  These terms, though
not strictly accurate, enjoy popular usage.  It seems senseless and even a bit
stuffy to continually challenge them.
