Hello,

Does anyone have the math behind the equation 8" per mile squared?

I'm in a deep conversation about FE with an influential person in a church denomination. He is an engineer and loves math. I've been working with his equations — which he says debunk the Flat Earth. We haven't got to the actual observations yet. We are just trying to iron out the math.

His big equation deals with the calculation to find the distance to the horizon.

When I asked about the calculation of the earth's curvature — he was totally clueless — even though he is the "spokesperson" on the FE topic.

So I mentioned 8" per mile squared. At first, he didn't want to consider a calculation like this. I convinced him to try. He came up with 16" per mile squared — which totallly baffled me. Plus, it would only help the FE arguments.

But I told him I would look for the math behind the 8" per mile squared.

Can someone help me with the math?

Thanks.
