First as a Joke My girl friend sittting by holding the swiming pool hand rail looking with no water which has flow here and there i will hold her and kick the floor and fly - i must have a suction battery operate fan to continue my flight by turning the direction i will reach Mcdonald where i will not eat anything hameed-

Hmmmmmmmmmmmmmmmmmmmmmm! maybe i will soar high and visit the ups downs countries which i couldn't visit when there was a gravitational force ! lol

Then I can fly whout any devices...wow....often dreamt of that...so cool...hehe....

If you mean no gravitational force in the whole universe ,not only the planet earth ,then it is like reversing the big bang theory. We will be squeezed and smashed in no time between our planet and another planetary body or any space object and we will eventually ( we people and every single entity on this planet ) be part of a big mushroomed mass. We will form partly the surrealistic artistic surface of the mass.

i think garbage will float with us.can you imagine all things are floating in the air. cowboy...
