Noted physicist Stephen Hawking is given the opportunity to try zero gravity. This experience will be doubly nice for the great scientist as he has suffered for a long time from paralysis. I wish space science has already developed to something nicer, such as to be able to offer him a weekend vacation in the Andromeda galaxy:)
The first time, it's a KLUDGE! The second, a trick.
Later, it's a well-established technique!
