LOL

That's too complicated for me!

I just want a simple answer.

Average person on the beach watching average ship go over curve.

How far out?

Then why did you ask for details? There is no "average" scenario of which you speak. You have to have a point of reference to DO the math and physics involved, which is why I didn't want to get into this stuff.

Everything is relative to something else. An "average" beach in North America is different than an "average" beach in Australia. An "average" curve on a fastball is different than an "average" curve on a golf swing. When I take out my camera, an "average" picture with automatic exposure is different than one with manual exposure.

There really is no such thing as average for your scenario. You need to figure out solid and stable objects to work from and allow for different environmental situations that can alter your math. That is why I gave the height of the tree, the sea level and so on.

Oh, and don't forget to factor in what you had for breakfast, of course! LOL

No. That's silly.

We are talking about an object going over the side of a ball so it's hidden from view.

That's all.

It's ubiquitous on beaches around the world.

Person stands on beach and boat disappears over the curve.

Average distance should be very easy to calculate give or take a mile.

That's all I'm asking.

What height is the ship, what height is the observer (eye height)? We need a few more parameters.

When we have those, we can calculate it as described here: https://physics.stackexchange.com/questions/593064/how-to-calculate-how-much-of-an-object-is-hidden-due-to-earth-curvature

Earth's radius is 3959mi or 6371km.

Or we use this simpler formula: h = 6,371km * (1 - cos(0.009° * d))
We could solve for d here if h is known (too tired for that right now).
Let's assume the observer is on water level, and the ship is 30m high.

6371 * (1 - cos(0,009 * 19,55)) = 30m
So that gives us roughly d = 19,55km fo ar distance with the assumption of no atmospheric effects going on for the ship to stay visible longer or shorter.

So if I understand this correctly that's about 12miles out.

Is that right?

Do others here who favor the Ball Earth model agree that's a pretty good average?

I've heard some say it would be at about 3 miles out.

I'm really not interested in the gobbley gook.

Just a simple answer.

I'm okay with, "It would probably be "between 3 to 12 miles" according to standard calculations.

What do the Ball Earth model proponents think?

Does this sound about right?

Brain is already mush for today, back is bugging me from shoveling, and I could only wish there were more sun around here! I don't trust a whole lot of what NASA says, but it cannot all be garbage.

It doesn't all have to be garbage, but since NASA has been demonstrated to lie, and lie a lot, then nothing can simply be accepted by their authority. We can't simply take their word for it. Really the biggest argument your average person has for globe earth is because "NASA has pictures". Very few can cite any actual scientific evidence. Of the few who can, it's invariably the boats disappearing over the horizon. 99% of the popular perception comes from NASA and just the sheer force of it having been implanted in everyone's minds since earliest youth. Every kindergarten class has a globe in it.

I noticed that you did not comment on anything about the pictures of Christ the King with a globe that I brought up. Why is that?
