An infinite flat plate is easy (the field is constant), and the field along the axis of a circular disc is also doable (I do it for the electric field in my first year lecture course). Very close to the disc the field is constant like an infinite plane, very far from the disc the field is 1/r^2 like a point source.

The field of a circular disc off-axis for intermediate distances would be a whole lot more difficult.
Not actually difficult numerically, though. My physical optics simulations do that all the time.

Yeah but gravity doesn't exist. The earth is just constantly accelerating upwards, hence the perpendicular "gravity" in all locations. You arrogant science types know nothing.

Great sci-fi story about a journey across a planet with high spin, causing it to flatten into a disk. Low gravity at the start, out at the rim, increasing as they travel towards the pole.

How long has it been accelerating upwards? 4.5 billion years? Must be going pretty fast by now. Like a million miles an hour or something?

So you'd think, but science knows nothing.

The change in red shift of stars and quasars would be pretty apparent, as well. What with having to make special relativity corrections within a year of accelerating at 9.8 m/s²

Ah, but the rest of the universe is accelerating with us too.
My avatar was a scientific result that was later found to be 'mistaken' - I rarely claim to be 100% correct

Something like Mach's principle then probably kicks in, suggesting that there'd be no inertial effects from such an acceleration, and hence no gravity.

Wtf are you on about? There aren’t any other stars, it’s just a dome above us with some lights.

Genuinely this is a flat earther thing.

Yeah, I know.

But then they have to explain where the spaceships and the signals emitted by radars go.

Also, why does satellite TV work.

Only if they're playing by (y)our rules. Which they're not.

What we really, really, really need is for Theorist to come and explain it all for us...Or one of those berks who drop into ISF to explain EVERYTHING!!!!!11111111111111!!!!!

I like the Concave hollow Earth theory which is also apparently a thing
Have you considered stupidity as an explanation

It must be nice knowing that you know something the rest of us poor benighted fools can't or won't accept. I so wish that magic was real. And unicorns. But not zombies, they're just annoying.

Andy? Is that you?
I was wondering how you were doing?
How are you mate. Good to see you back.
I hope you beat that bastard cancer once and for all (or as much like so as can be)
