Ah okay. Well you're talking to a scientist who took lots of physics courses and even some history of science courses (that covered how we got many things wrong). Frankly I don't blame you, given what politics and money have done to science in recent years. Not to mention the rise in Scientism - the unquestioning belief in The Science (TM) even if The Science changes every five minutes. In any given moment, The Science is truth, no matter how contradictory to evidence.

That said... I mean, you can try to make a flat earth model work. No one's ever done it. It takes some wild and wonky physics; my friends and I tried it in college, and again actually about 8 years ago at my old job we ran it with another group of scientists. Things like the annual path of the sun, sticks at different latitudes casting different sized shadows at the same time... and yea, gravity is real. It's funny in that video they show water spinning off a tennis ball as some sort of proof that water can't stick to a spinning ball, but try it yourself. If you spin the ball REALLY fast, you may get it dry, but odds are it will still be damp because of the adhesive forces between the water and the surface. Also gravity doesn't just work on large objects, but it only works appreciably on large objects. But you can run the Cavendish experiment yourself.

And I mean... without gravity, what holds us to the flat earth anyway? Are we constantly accelerating up? I guess that'd have to be the case huh. But why doesn't anything get any closer? Is it all accelerating up too?

Kinda funny, thoughts like that sort of do get into how gravity works in a 4D universe, but I mean... you don't really seem to believe in 3D, so I'll skip that. Good luck.
