maybe newton?
yes it was Isaac newton... the law of gravity!
Only problem, of course, is that this is actually something that he conclusively disproved. If an object has a sufficiently high upward velocity, gravity, weakening evermore with increasing distance, will not be able to bring the object down. It will be in a 'hyperbolic' orbit.
In other words, it is popularly attributed to him, but it is unlikely that he said it.
This quote came from the film Casablanca. The quote was said by the character Ilsa Lund.
