Well, I do need to sleep, eat, and go to work.
I'm also getting a bit muddled since I'm in several flat earth threads right now; I'm losing track of where I have posted stuff. I posted a pretty satisfactory answer about gravity somewhere but there are some additional thoughts I'd like to throw out there, so here goes:
First off, one flat earther recently put things really well. He said that we can conclusively prove that the Establishment is lying to us about the globe, but that does not mean that the flat earth community can explain every natural phenomenon with 100% certainty. Seeing the lie and knowing all the secrets of the universe are two different things. Additionally, the recent flat earth resurgence has only been around since 2012-2014, so obviously the glober establishment has a really big head start and are quite entrenched. I agree with him on all this 100%.
Newton did not discover gravity; he only came up with an explanation of it: mass attracting mass in the view of modern scientism. It's a theory that has never been proven. Now let's be clear. Things fall. No one, not even flat earthers, disagrees with that. I think flat earthers do themselves a disservice by saying things like, "Gravity doesn't exist" and then not thoroughly explaining what they mean. What they mean is that the explanation of mass attracting mass is inadequate. So let's talk about gravity's acceleration of ~9.8 m/s^2. That's an observational fact. I'm not denying that. But is it mass attracting mass that is CAUSING that? Unknown. We can use the observational FACT of 9.8 m/s^2 to make predictions without signing off on the concept of mass attracting mass.
But let's say - for the sake of argument - that gravity works exactly like modern scientism tells us. "Gravity IS mass attracting mass." That's not a problem for a flat earth model at all. Why not? Because if the sun and moon are small and local, WHERE IS ALL THE MASS IN A FLAT EARTH MODEL? In the Earth, which means stuff is still going to fall down towards the Earth.
But - and think about this really carefully - the idea that gravity IS mass attracting mass is actually HUGELY PROBLEMATIC for the heliocentric model. In order for the heliocentric model to apply, gravity has to be SELECTIVELY APPLIED. The Sun only captures planets. The planets only capture moons. Why don't the moons have moons have moons have moons? We should see incredible complex stepped gravitational systems all the time. Why doesn't a planetary alignment, when all the planets line up and all that gravity is pulling things in one direction - why doesn't this RIP entire planets out of their orbits? Why don't we feel a shock here on Earth whenever Mars or Venus are nearby, pulling us in a different direction? Why, when the Moon is slingshotting around the Earth in the direction of the Sun, doesn't the Sun capture it and rip it away since all the momentum AND the Sun's gravity should be moving it towards the Sun and not the Earth?
This is called the "three body problem" in science. Gravity can be modeled perfectly between two objects, a planet and moon or a planet and sun, etc. But when you add a third body, each body is acting on the other TWO which will degrade any orbits involved. With an entire solar system of bodies acting on each other... the system would not sustain itself in an orderly fashion for even a year without degrading. You would never have an order cycle, not even once.
