Maybe there is another job for the shadow object besides just accounting for the lunar eclipse. The sun and moon must also line up in such a way as to cause the variations in the regular tides you see. In the heliocentric model the moon can be on the same side of the earth as the sun and then both bodies can exert a gravitational pull on the earths water and cause a variable strength tide. The sun is much more massive but is much further away from the earth than the moon, so the gravitational effects of the sun and moon are different. The moons gravitational pull on the earth’s water is about 2.5 times stronger than the sun. With the FET model the sun and moon are opposite of each other and are of variable distances in different seasons. I also don’t see in the wiki where the sun exerts any gravitation pull on the earth’s water, just the moon and stars. If the FET model were true, I would then expect to see tides that were different in different seasons of the year on a regular basis. Maybe the FET model will have to be adjusted so that the shadow object will have some tidal effects as well. If the shadow object did that then, by definition, it would have to have some mass. You then should be able to detect and measure it. You can easily see other objects when the sun is in the sky. I have personally seen the planet Venus and even used it as a navigational body during the daylight hours.
That is something to consider, that is seasonal differences in tides due to sun and moon distance changes in FET.
But if I'm not mistaken FET doesn't adhere to the concept of gravity. I haven't read what FET claims tidal effect cause is.
The "Shadow Object" if that's what we're going to call it, my not have much mass, no gravitational effect on anything? Obviously we can't see it, detect it with radar or anything, therefor we don't know what it is or even if it exists.
However, it might be man made and cloaked, this would fit the frame of FET and the idea that there's a huge conspiracy and they're hiding the truth from us? Don't laugh, if you're going to believe the earth is flat you have to reach deep, fetch far for evidence.
The problem with that theory though is FET would have us believe that man doesn't posses the skill, technology, modern vessels and ingenuity to properly map the earth. How would we figure out the sun, moon and earth line up to cause eclipse effect with a 4th invisible object throwing us off track?
I guess my point is, The "Shadow Object" brings up more questions than answers.
