Lunar Eclipse??

If earth is flat and sun is smaller than earth the what is "Lunar Eclipse"? How you will explain it?

I have the same question, because the whole Lunar eclipse thing is not really covered here.

I believe there are 2 possible explanations for lunar eclipse with the FE enthusiasts.
Some say there's an invisible disc floating about that obscures the moon and sun during eclipse. Or there is the FE moon shrimp phenomenon to explain moon phases and perhaps lunar eclipse.  I don't know which is more plausible but I will go with the shrimp theory because I like shrimp.

There's also Rahu, the mythical black sun.

We know that all lunar eclipses occur at the full moon, so first of all let's just at the positions of the sun and moon at this time.

The Phases of the Moon
When one observes the phases of the moon he is simply observing the moon's day and night, a natural shadow from the sun[1] illuminating half of the spherical moon at any one time. The lunar phases vary cyclically according to the changing geometry.

The diagram below is how I interpret the geometry at the time of a full moon. Note that the distances are to scale, but the object sizes are grossly exaggerated (though the sun, "shadow object" and the moon are to scale with each other. The sun and moon are placed 180° apart on the equator.


With the moon on the opposite side of the equator there seem to be a couple of problems:

• Half the moon is illuminated (as it should be), but someone directly under the moon, where it would be midnight, would see only one half of this! So it would look like a half moon.
  
  
• An observer where the moon is just rising (or setting) WOULD see almost all the moon. So the moon would look full as rises, but become a half moon when overhead!

Now onto the lunar eclipse.
This is what "the Wiki" says (bits about solar eclipse etc, removed for brevity):

The Lunar Eclipse

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

A Lunar Eclipse occurs about twice a year when a satellite of the sun passes between the sun and moon.

This satellite is called the Shadow Object. Its orbital plane is tilted at an angle of about 5°10' to the sun's orbital plane[2], making eclipses possible only when the three bodies (Sun, Object, and Moon) are aligned and when the moon is crossing the sun's orbital plane (at a point called the node).    . . . . . . .  A lunar eclipse can be seen from the entire half of the earth beneath the moon at that time.   . . . . . . . . .

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The shadow object is never seen because it orbits close to the sun.

It is estimated that the Shadow Object is around five to ten miles in diameter. Since it is somewhat close to the sun the manifestation of its penumbra upon the moon appears as a magnified projection. This is similar to how during a shadow puppet show your hand's shadow can make a large magnified projection upon your bedroom wall as you move it closer to the flashlight.

Again, this is my interpretation of that geometry:
With the "shadow object" (Rahu?) so small, there is no way for the "shadow object" to cast any significant shadow. We would get a slight reduction in illumination and nothing more!

If my interpretation of the geometry or light paths is incorrect, I would love to be informed, but please no massive refraction or magnification in the atmoplane, there is no atmoplane 5,000 km up!

[1] A "a natural shadow from the sun", really?

[2] If the "shadow object" can never be seen, how is this determined "Its orbital plane is tilted at an angle of about 5°10' to the sun's orbital plane"? I can guess, that's the orbital inclination of the moon!

Lunar eclipses are a result of when the moon is opposite the Sun, and its light must go far further in order to make it to the Earth. As it rotates into view, the light is distorted as it would after going through more air, and becomes more red.

the sun is always higher than the moon and lights it from behind / above ..... therefore there is another planet which rotates with both of them at such a speed as to cause 1/4 moons etc.

Evidence?  Or at the very least give us a diagram of what you mean!

That would preclude a full moon.
