where did everybody go, was it something i said?
You told us not to answer to you anymore. Besides, 30 minutes in a forum like this isnt that much.
I'll explain where you got it wrong, though.
considering that a total solar eclipse only happens because the moon is exactly 400 times smaller than the sun
Wrong. If you have two different ecliptical orbits, you can see that the size varies. If the Sun and the Moon where on the same plane, every single month the Moon would occult the Sun, and, depending on the aparent size of both objects, it would be total, or partial.
Since the Moon's orbital plane around the Earth isnt paralel to the Earth's around the Sun (it is about 5º degrees off), then another condition has to happen for an eclipse to occur: depending on the viewer's position, the stereo-angle (angle in 3D) that the Moon has to be has to coincide with the Sun's. Since this depends on the position of both bodies AND the POV, eclipses are very rare. This phenomenon is explained everywhere, I got this explaination back at high school. We even got a nice mobile with a light bulb and diferent sized balls.
