Further:

(1) Why does smoke rise from chimney stacks if gravity is supposed to pull it down?

(2) How is gravity powerful enough to keep the world's waters stuck to a spinning ball but weak enough to allow butterflys and birds to fly with minimal effort?

(3) Why don't insanely massive mountains like Mt Everest have tiny hairballs or dustballs orbiting them? No seriously, Everest weighs 357 trillion pounds by this estimate assuming a volume of 2.1 trillion cubic feet.

(4) Why hasn't the all powerful force of gravity sucked the moon and earth into each by now?

There is so much wrong with the theory of gravity that it will make your head hurt. Gravity does not make things fall to the ground. Things fall because that's the way the earth was when we found it. Scientists don't know ANYTHING about the universe because they're not the ones who created it. Scientists are just speculators about how things work when in reality they could be very very wrong. How about we agree that things fall and leave it at that. Our speculations are useless because we don't know. Science is like the literature circles we use to do in school where everyone would pitch in and speculate about the author's intentions when they wrote a book. "Well I think the author included this metaphor to show that ...." "Piggybacking off of that, the ending of the book was likely inspired by this other novel ..." All of which is pure speculation. Ask the author. He knows. He wrote it.
