Flat Earth Debate / Lunar eclipses and the "shadow object"
« on: May 26, 2017, 12:47:54 PM »
The standard FE explanation for eclipses (both solar and lunar) is that a mysterious "shadow object" - which is evidently round and opaque (maybe a disk, maybe a sphere) - gets between the observer and the sun or moon respectively.   This is intended to explain why there is a curved shadow on the moon during a partial lunar eclipse.

In RE terms, the shadow of the curved Earth cast onto the moon explains the curved shadow.

My new problem is how FE'ers can explain why this "Shadow object" or "antimoon" doesn't block out the stars - during a partial lunar eclipse or when moving across the sky between eclipses...that's not explained at all.

In RE theory - the stars are luminous and are clearly visible - even when we see them right next to the semi-eclipsed moon...which we clearly do.

In FE theory, during a partial lunar eclipse, the part of the Shadow object that does not overlay the moon should block starlight from stars in that small region of the sky...but it doesn't.  Furthermore, just before and after the eclipse, we ought to see a circular region of blocked-out stars moving towards and then away from the moon.  No such observations have ever been made...I've watched countless lunar eclipses - and I have not seen a blotting out of the stars close to the moon in the time leading up to, and following the eclipse.

I think FE proponents have to rethink their eclipse ideas...what's there right now doesn't fit with simple naked-eye observations.

Flat Earth Debate / Question about perspective.
« on: May 18, 2017, 12:52:05 PM »
So I was reading in the Wiki about the FE "perspective effect" - as shown in this diagram:

It's an interesting concept.

It says (in effect) that perspective isn't a "symmetrical" effect - it forces things downwards toward the horizon with increasing distance - right?   I say not "symmetrical" because it evidently doesn't push things that are below the horizon upwards.

Then we're told that this is a defect of human vision - but that can't be the cause because cameras produce the same perhaps cameras have the same effect built into them so they take "natural" looking photos?

Trouble with that is that if I turn my camera upside down and take a photo - the same effect happens - the depression happens downwards.

For that to be the case, then this has to be caused by the Earth/Atmosphere - and not by the camera/eye.

So I think the Wiki could use some correction here.

Flat Earth Debate / Tides.
« on: May 17, 2017, 04:09:20 AM »
According to the Wiki, tides in the FE theory are due to gravity from the sun and moon.

How does this explain that there are TWO lunar tides in each 24 hour period?  In the RE model, the Earth/Moon system orbit around a point a little off-center from the center of the (round) Earth. The tide that happens when the moon is overhead is just gravity, same in FE and RE physics.  But the second daily tide (which happens in RE theory because centrifugal force produces that second tide due to the off-center rotation of the Earth.

What is the FE explanation for that second daily tide?
