I would agree that it is not based on any true science. Rather, I suspect
hydrogen displacement was chosen because of the potential "sounds cool
factor", since it sounds like a nautical term. Some sci-fi's (not all) like
to draw comparisons between seaships and spaceships. But as I am among
them, I guess something that has the "sounds cool factor" was what I was
looking for.

True. Although if we want to be really accurate, then technically 'volume'
and 'mass' are not the same thing. I am no science expert, so I don't know
the specific jargon. But I am pretty sure on this point. ...Anyway, if
someone were to measure as ship by volume, then I assume the units of cubic
feet or cubic meters would be used. But what is the unit of measurement for
mass?
