You can trace it out yourself, Dave. Get Google maps and trace it out. I did! My curve wasn't as smooth as the image on your map and the image on your map isn't as detailed as reality but my rough trace out came to be about 20,500 miles. The more detail the more miles and a more detailed course...

You can only see down the line of sight, Dave. It makes no difference whether you're using a telescope or not. The only way you can see past the horizon is if the light is being bent around the curve of the Earth. What you don't seem to grasp is that the implication of what you are saying is...

I'm not disregarding anything! And, yes atmospheric refraction it is being denied, or at the very least ignored. And yes atmospheric refraction most certainly does give sufficient curve to explain what is seen in that video. What CANNOT be explained at all by the flat earth folks is why the...

Dave, Just a quick question. What do flat earth folks think this is a picture of? See full resolution image HERE. How do we have high-resolution pictures of a place that doesn't exist?

Notice he went clockwise with Antarctica on his starboard side. Think it throught, Dave. Is that the way it would work if he went clockwise around the flat Earth? How would you keep an ice wall to you starboard (right) side if you were sailing clockwise (i.e. turning toward your starboard...

Not sure who this was aimed at but if it was intended for me, everything you said here is irrelevant.

I never said a word about mirages. A mirage would, in fact, be the opposite of what I said. A mirage happens when light is refracted up and away from the surface of the Earth. What I'm suggesting is the opposite of that. "Suggesting" being a generous word since atmospheric light diffraction...

It wouldn't even be that complicated. If the flat earth model is accurate then the coast of Antarctica should curve around in one direction relative to the ship while on a spherical Earth it would curve around in the opposite direction. So, if a ship has the coast of Antarctica to its Port side...

In regards to the size of Antarctica on the flat Earth vs a globe, the flat earth folks might get away with suggesting that no measurement of Antarctica has been made. They can call any such measurements fraudulent or whatever because no one who discusses this (virtually) has been to Antarctica...

That's almost got it. It isn't "those who measured Antarctica" it's "those who claim to have measured Antarctica". In other words, they deny that any such measurement has ever been made or even that it could be made. Poe's Law is truly in full effect here.

Well, it didn't take long for me to confirm that atmospheric refraction does indeed play a very significant role when performing such experiments... Effect of atmospheric refraction If the Earth were an airless world like the Moon, the above calculations would be accurate. However, Earth has an...

While I haven't yet confirmed this, I really think that atmospheric refraction has to be accounted for, which the video does not do. Also, the video sort of testifies against its own premise. If the Earth was flat, shouldn't he have been able to video the entire bridge pillar all the way to the...

I'm out of time for today. I want to know about how the atmosphere would interfere with my lake experiment. My intution says that it can be ignored because the light beam doesn't enter or leave the atmosphere throughout the experiment and so it seems like the light should travel in a straight...

You're absolutely right! My bad! I made an error thinking that the fall away is linear. It is, in fact, geometric. The curvature of the earth is 7.98 inches per mile SQUARED! So the first mile is 8 inches, the second mile would be 32 inches, the third would be 72 inches and so on. If 3 miles...

Beer AFTER!!! Not before! :cheers:

I've mentioned this once before but since we're talking about measuring the curvature of the Earth I thought I'd bring it up again. A really good experiment to measure the curvature of the Earth, that anyone could do with minimal expense is this... Find a lake. Pretty much any lake will do but...

Exactly! It gets way worse when you realize that minuscule number is nine times bigger than the real number!

There are at least two things wrong with this thought experiment. 1. Roads are built by people who can introduce more flatness than is there naturally. Therefore roads are not the best things to use for such an experiment. It would be better to use something we know is "level" such as the...

This is simply false. First of all, the vasy majority of land based projected are on a scale too small to worry about the curvature of the Earth. But on large scale surveys, corrections are made for the curvature of the earth. Such corrections are more noticable the further north you go. On...

I get that but it wouldn't hurt for you to modify your arguments based on the arguments I make. You should keep a scorecard. It would be somewhere in the neighborhood of :Clete: 230 :devil: 0 You haven't even established that it was any influence, must less an important one. My bet is that his...
