Flat Earth Debate / Re: Gravity on an infinite plane

Work on your reading comprehension, your "math" breaks down long before the integrating, don't try to deflect the issue by assuming I don't know what integration is.

Before you can proudly flex those high school math muscles, learn to make correct assumptions (or maybe you made the wrong ones on purpose, so it looks a little more complex and believeable, so that the gullable morons on this forum actually think you got something).

I am not the one trying to will an object with infinite volumn, mass and gravity into existance.

PeKu, the approach "calculating gravitational force just by watching their center of masses" is only correct when you have objects which are small compared to the distance that seperates them. In the other case you have to integrate over the whole mass.

The funny thing is that an infinite plane is symmetrical everywhere, therefore you can say that the horizontal parts of the forces cancel out.

Blabla, blabla ...

So the earth is "small compared to the distance"? The formula is correct when you assume an average, uniform dencity accross the whole object ... which is exactly what the paper does. Oh my god ...

And the funny thing is that saying "an infinite plane is symmetrical everywhere" actually supports my statement, it's just a different way of saying "there is no centre".

Try harder ...

Next Problem ...

"we can assume that all horizontal parts of the attractive force cancel out"

-> No, we cannot, because the gravity formula calculates the force between the two centres of gravity of the two objects, there are no other vectors cancelling anything out, the formula is already reduced to exactly one vector ... so yes, your "infinite plane" gravity - that can't exists, but lets humour you there  - would not be vertically, except right above your imaginary centre (that doesn't exists on an infinite plane, either, as I already mentioned in my previous post).

Stop making shit up.

I better stop reading this ...

You forgot a few things in your assumptions ...

"The earth is an infinite plane"

-> That means, no matter how thick, that V - Volume - is infinite

-> That means, no matter how low the density, M - Mass - is infinite

-> That means that gravity would be infinite on every possible point on this "plane"

-> But that also means that this plane does not actually have a centre of gravity, because all points on this plane are equally - infinitely - far away from the - technically non-existing - edge. You trying to glance over that problem by "assuming the plane to be symmetrical via rotations" doesn't just make it so - either infinite or a centre, not both

-> That means the distance between the centre of gravity of the two attracting masses r is undefined and can't be used in a calculation

Basically, the whole thought-experiment has already broken down at this point ... twice, on your first formula. Infinite planes can be used in math and geometry, but it doesn't work with actual physical properties, genius.

This is like one of those math "problems" created by "dividing by zero" or other tricks that make any calculation after that point mute ... "Einstein would love that!"
