137. When the Sun is visible during a lunar eclipse this disproves the heliocentric model

"Another assumption and supposed proof of Earth’s shape, heliocentrists claim that lunar eclipses are caused by the shadow of the ball-Earth occulting the Moon. They claim the Sun, Earth, and Moon spheres perfectly align like three billiard balls in a row so that the Sun’s light casts the Earth’s shadow onto the Moon. Unfortunately for heliocentrists, this explanation is rendered completely invalid due to the fact that lunar eclipses have happened and continue to happen regularly when both the Sun and Moon are still visible together above the horizon! For the Sun’s light to be casting Earth’s shadow onto the Moon, the three bodies must be aligned in a straight 1 80 degree syzygy , but as early as the time of Pliny, there are records of lunar eclipses happening while both the Sun and Moon are visible in the sky. Therefore the eclipsor of the Moon cannot be the Earth/Earth’s shadow and some other explanation must be sought." 



Dubay again ignores atmospheric refraction as a cause of  the observed phenomenon

Atmospheric refraction causes astronomical objects to appear higher in the sky than they are in reality.

You can see this effect at most sunsets because when you see the Sun sitting on the horizon, it is already below the horizon. Our atmosphere acts like a lens and bends the sun's image just above the horizon, allowing us to see it.

One of the ways you can prove to yourself that atmospheric refraction is actually taking place is to observe the shape of the Sun as it sets.   The refraction increases closer to the horizon.

This difference in refraction between the top and the bottom of the observed Sun results in the shape of the Sun being squashed vertically, often easily visible with the naked eye.


Another effect also caused by the refraction that you may have noticed is that at sunset Sun appears to linger on the horizon and then speed up immediately before disappearing. 

So yes, the Sun can still appear to be above the horizon when a lunar eclipse is taking place.

Also note that although Dubay states that "some other explanation must be sought", he makes no attempt to actually explain it himself.  That is because flat earthers have no explanation.

127. Straight reflections of sunlight and moonlight are impossible on a spherical Earth

Image
"The fact that the Sun and Moon’s reflections on water always form a straight line path from the horizon to the observer proves the Earth is not a ball. If Earth’s surface was curved it would be impossible for the reflected light to curve over the ball from horizon to observer." This is a flawed argument because Dubay does not understand how reflections operate Although he doesn't describe it very well, I presume that Dubay is referring to the angle of reflection from a curved surface.  I.e. the curve of the Earth would mean that the angle of reflection off the surface would result in nearly all the light  not reaching the observer's eyes. The fact that, if this was how reflections worked, that the same would be true on a flat Earth seems to have escaped Dubay's notice. This type of reflection is called specular reflection, and takes place with mirror like surfaces.  Generally the surface of the water is not perfectly flat so the reflection of the light...

Debunking Eric Dubay's 200 proofs the earth is not a spinning ball

Image
Conspiracy Baloney aims to provide resources to counter to the influence of the crazy anti-science conspiracy theories that are out there. This blog is specifically to debunk Eric Dubay's " 200 proofs the earth is not a spinning ball", that I have found flat earthers often cite. There are quite a few resources out there that comprehensively debunk this book, but I think that one more voice can only help.  I have tried to keep the rebuttals as non technical as possible. Eric Dubay’s proofs are laughably simplistic and demonstrate an almost complete lack of understanding of maths and anything scientific or technical. A list of "proofs" that show Dubay is an idiot He also likes to give historical quotes as proofs.  Typical are quotes from the 1800’s but he even has one from before 1600!.  Not only are these opinions not proof of anything, but the fact that he can’t provide quotes from more up to date sources destroys their credibility. Worse, ...

If Earth was a sphere the visible stars would be different

Image
The visible stars are a big problem for flat Earthers because what we observe is 100% consistent with a spherical Earth and completely impossible on a flat Earth. Their solution?  Simply to lie about what is observed.  These lies include denials of observations that are impossible on a flat Earth and pretending that observed stars would be impossible on spherical Earth. For the latter, it could be that Dubay simply can't do simple trigonometry but I think that he is once again deliberately lying. The strange thing about this is that everyone is capable of putting these claims to the test simply by looking up at the night sky.  The fact that flat Earth believers refuse to put these "proofs" to the test tells you that they are not really interested in truth, they are only interested in feeling good about their beliefs and will simply unquestioningly accept as fact anything that backs up these beliefs. Ignorance truly is bliss. 99...
