At what distance does gravity stop? If I hold an apple a meter above the Earth's surface, then obviously there is gravity, and there's "gravitons" going between the apple and the Earth. What if I take the Apple to the moon? Still gravitons between the apple and the Earth? Or does the moon block the gravitons from Earth? How about taking the Apple to Mars? Is it still connected to Earth? What about taking it to to the nearest exoplanet?

I dunno, gravity seems kinda sus.
