And if you are really certain that you are talking about gravity, your knowledge is still framed within Newtonian mechanics. You will have to understand the basics of Einestein's general theory of relativity to understand that you don't feel gravity even now. What you feel is the repulsive electromagnetic force due to (and opposes the effect of) the bent spacetime. If earth weren't here, that just alters the way spacetime is deformed, and you will still be in a free fall along a geodesic trajectory.</p></blockquote><p></p>
