The flat earthers have yet to explain the dimensions and structure of their "shadow object". Diameter? Chemical composition? Thickness? Orbit? Periodicity? Who discovered it and when? A citation in any reference books? Its location on a star map?
C'mon flat earthers... details please.
RE to FE: "How do you explain the lunar eclipse?"
FE to RE: "It is a shadow object but let's speak no more of it!"
RE to FE: "Please explain this thing, I would like some details to better understand your FET"
*crickets chirping*
That pretty much sums it up.
