Thanks happenby. The only "truth" I've rejected, of course, is doctrine according to the Church of NASA.
I think that Neal may have a more difficult time explaining the issue of the shadow cast by the moon during the eclipse, as this has already been discussed in a good pro-flat earth video, here:

.
This is a great example of how ignorance can produce nonsense. This video is full of misunderstanding and convoluted contradiction. So it's nice to see that this eclipse is rattling the cage of flat-earthers. Because they can't predict its course using their model, and with their preconceived wrong idea, they cannot fathom to comprehend what is happening. Every which way they're off course. It would take PAGES to comment on all their mistakes in this video.
.
The post I made above gives an idea of the two kinds of shadow the moon will cast, and the two kinds of view people on earth will see. I will be in Los Angeles, where about 50% of the sun will be covered by the moon. That puts us in the penumbra (not the umbra), and many shadows under trees and the like will show images of the eclipse in the sky like this:

I gotta turn in for the night. Will check back tomorrow.

Complete nonsense, Neal. Goodnight.

No, that doesn't work at all. There is no "cone." That's not how light works. I did a little experiment this afternoon, and the shadow was the same size as the object that I put between the flashlight and the surface on the other side of the object. Light does not travel the way you have described it.
.
You can't use a flashlight. Duuh. It's too small. You need a LARGE light source. The sun is a lot larger than the moon.
.
There is no cone? What are you talking about? If you have a LARGE light source (larger than the ball you're shining it on), up close you can see two shadows. If you move further away the outside shadow quickly disburses and only the inside shadow remains. Of course, in our limited environment it's hard to get the same results you can get in space and a vacuum with no atmosphere. 
.
The point is, at the great distances of the sun and moon, their light and shadow are cast at great intensity and long distance, which is very hard to image in scale and even harder to duplicate without distortion. You would really need a 5' diameter LASER light source at 100' and a ping-pong ball casting a shadow over a basketball separated by about 30 feet. Something like that. Have to go. Sorry.

The image I posted isn't fake. It's just a photograph someone posted of the ground during an eclipse. There are hundreds of photos like this. I know they're accurate because I have seen this effect in person. Anyone who watches for shadows during an eclipse will see this sort of thing on the ground and building walls all around them, unless the sky is cloudy or very smoggy or full of smoke, etc.

Here are some more photos:

That's on the siding of a house, from the shadow under a tree during an annular eclipse.
.

This one is on a fence, showing a partial eclipse shadow under tree branches.
.

You can do this with your fingers against a wall -- just don't look at the sun!!
.

This one is using binoculars. Just be sure not to LOOK through them!!

The width or diameter of the moon casts a shadow toward earth that has a two-aspect conical shape. One cone is the total darkness where the sun is totally covered by the moon, and this shadow gets smaller the further away from the moon you go. The open end of the cone is the perimeter of the moon where the light side of the moon (lit by the sun) transitions to the dark side of the moon (in the shadow side). The point of this cone is the very end of the moon's shadow where a viewer would see the sun emerging all around the moon.
.
Maybe I wasn't clear enough -- the two shadows cast from the moon are CONCENTRIC, meaning one is inside the other. They are not side-by-side. The outside shadow is fuzzy and fades away at the edges, while the inside shadow is more distinct, but it too has a blurry boundary. Some diagrams make them appear sharp and crisp but that's just an easy way of depicting a picture that is very difficult to describe. To show it accurately would make it very hard for the viewer to understand because the image is inherently blurry. So for clarity's sake they make the image sharp, but ironically, that makes it inaccurate.
.
One more thing about the movement of the sun and moon during the eclipse.
.
There are two ways of thinking about what you see. One is, that the moon is "still" and the sun is going behind it. The other is that the sun is "still" and the moon is moving in front of it. But the reality is both are moving. You have to think about this before the eclipse happens, because if you wait until it's happening it's too much to think about all at once, and you'll be confused.
.
When you realize both are moving in the same direction, then you can observe that the sun is moving faster. It's passing up the moon, with the moon in front and the sun behind it. Kind of like you're walking along a highway and look across the road to see a shiny white car passing a slower black car that's in the right lane. For a moment, the shiny car is hidden behind the black car, and then emerges on the other side. They're moving from left to right. But if you think that the sun is "still" and the moon is moving by, then it appears that the moon is moving from right to the left. So it makes a lot of difference how you're thinking while you watch. That's why it's so important to observe objectively, without prejudging what you expect to see.
.
Another very interesting phenomenon is Shadow Bands.

They look like this, but more like the surface of water, rippling. Very strange.
Meteorologists do not all agree what causes them or what they are, but they occur only immediately before the total eclipse, they move over the ground at about 5 mph, you have to run to keep up with them, they wave around like they're being projected onto the ground (which they really are!) and then they disappear as mysteriously as they appeared.
.

This shows how uninteresting it can turn out when you try to be scientific. The photo doesn't do justice to shadow bands which are really very interesting. I think you need to have a motion picture of them because their movement is very mysterious.
.
Perhaps some mysterious scenery would help! 
Here are shadow bands photographed in Egypt!!
