Flat Earth Theory / Re: Here's my take on what gravity is...
« on: April 04, 2015, 02:39:02 AM »
Why is the mass of the Earth falling faster than us such that we're stuck to it, instead of us also falling? Why is there a place of free-fall down near the bottom, but not, well, everywhere?

Well, I guess you forgot to tell us that you intend to move the mass of the FE about, not just add the pillars. So, you're willing to make a new dome-like shape for the earth to solve a flat earth problem with gravity and somehow balance the mass of the new shape so that the resultant gravity is 1 g down everywhere on the near surface of the earth. Good luck with that.

I never claimed a dome shaped earth. I just don't see how pillars pulling everything down would be a problem, because that's what we experience - everything gets pulled down.
Tell us how adding "downward" pillars doesn't make the earth dome-like. Draw a picture for us please.

Then please do use GR (or for simplicity's sake Newton's ULoG) to calculate g at the NP, equator, 80o S. We'll review your math and get back to you. (Do please be careful not to make the simplifying assumption that you can represent the earth as a point mass, as that assumption doesn't apply to your modified earth.) Thanks.

It would look something like this:

I don't know how to do the physical math. That's why I'm asking if this is possible.
And you have my answer. No, it would not be possible to balance out the GR gravity of a finite FE by adding four or so pillars to the bottom of the FE's edge. The details are in the math, requiring integral calculus.

You're joking, right? I actually just did the math, and it actually works out better than the standard, no-pillar model if (this is an important if) we do not presume acceleration.
