And near-future, cutting-edge technology may give you ground-level zero-g.
I'm referring to superconducting
magnets.
Small ones have already been used to 'levitate' a frog, I understand.
I can't find the URL undfortunately.
Superconducting magnets of extreme
magnetic force are apparently able to magnetically affect [normally] nonmagnetic materials [like biological material: flesh & blood], thus able to
repel/levitate them.
Voila! Counterfeit zero-g! Counterfeit antigraviational effects!...You won't
be able to tell the difference!
Imagine! In your lifetime [10-20 years?], you may be able to [pardon the pun] lay down 20-dollars, or 10-Euros, and get, maybe ONE-HOUR of ZERO-G experience from a room-sized superconducting magnet.
