Flat Earth General / Re: How does UA explain the decrease in gravity with elevation?

You see, these calculations for gravity that we use to do thing like gravity anomaly mapping, which helps us locate big heavy things in the Earth's crust, like ore bodies. They have these adjustments for things like latitude, elevation, free-air, standing next to big heavy things....
Like proper theories they make testable predictions.
If you are in an airplane you weigh less than you do on the ground.
Now the Mount Everest case, Mount Everest is largely made up of sedimentary rocks, sedimentary rocks are light, there is a large keel, also largely made of sedimentary rocks below Mount Everest that helps to allow it to maintain the elevation that it has achieved. As a result the amount of actual mass under you when you are on Mount Everest is not that much more different than if you are anywhere else on Earth. You still need to do some adjustments when you are doing high resolution mapping, but not bad.
But in the meantime, here is another quandary for you. In UA the acceleration would always be in one direction, and that direction would no vary depending on where you were on Earth. Meaning that if you had a very high resolution plumb bob it would always point straight down, however, since we have these wonderful gravity anomaly adjustments we find that if you are on the border between a really heavy thing (basalt) and a really light thing (sandstone) the plumb bob will lean ever-so-slightly towards the basalt, because although the center of gravity is the same no matter where you are (within reason) the area nearest you has much more mass to one side of you than the other.
Once again, UA cannot account for this.
