Wrong. Do this. Draw two concentric circles. The inner circle represents the earth's surface circle; think of it as the equator circle. And the outer circle is the moons path. And think of it as looking down at it from the north pole direction. Now draw a dot outside both of the circles to represent the sun. Now draw a line that connects the center of the two concentric circles with the dot that represents the sun. That line will intersect the Earth circle where the shadow begins and the outer circle where the moon is initially located. Now from that initial line draw two more lines that both go threw the center of the concentric circles with one line 0.6 degrees counter clockwise from the initial line and the other that is 15 degrees counter clockwise away from the initial line. At the beginning of the eclipse, the shadow of the moon is where the initial line that you drew intersects the Earth's circle as I have previously said. In one hour, that point on the Earth's surface has traveled to where the 15 degree line intersects the Earth's circle, while the moon is located where the 0.6 degree line intersects the moon's orbit circle. Now draw a line that goes through where the 0.6 degree line intersects the moon's orbit circle and the sun, and continue that line down to the Earth's surface. Notice that that line intersects the Earth's circle to the West of the place on the Earth's circle where the shadow started. Therefore the shadow has traveled from East to West.

You didn't count the fact that the Sun is pretty far away and that makes the Moon's shadow travel in relation to Sun's position. In your concentric circles example you would have to draw a dot pretty far away from the circles representing the Sun and draw the shadow of the Moon by starting from the far away Sun, then going through the Moon's orbit circle position and on to the Earth's surface circle. Then the shadow will go faster than any point on Earth's surface.

The light source being far away is irrelevant. The fact that the object causing the shadow, the moon, is close is what matters. Face the fact, I just proved that for an eclipse where the shadow travels along the equator the shadow will travel from East to West. And I'm sure the same can be proven for all other eclipses. But if it isn't true for all other eclipses, then at least for many others it should be true for. But all recorded eclipses from what I am aware of are west to east. We got some trouble in paradise folks.

I wrote it weird. It doesn't matter that much that the sun is as far as it is. It still relevant that the light is coming from the sun as it determines the angle of the shadow.

The facts I have wrote here together with the video showing example of the shadow's travel on the surface should be enough for you to understand why the eclipse goes from West to East.

You are just saying shit without proving anything. Give a proof of what you are trying saying, or don't say it at all. You say a flaw in my proof is that I didn't take into account the sun is far away, and then when I call dog shit on that, you say oh wait, the sun being far away actually doesn't matter bwahaha. My proof, together with the fact that no one is yet to point to a flaw in it, should be enough for you to start entertaining the possibility that the video the OP originally posted might in fact be truth. So unless you have a coherent proof of what you are trying to say, stfu because you are a waste of my time.
