Debunking flat Earth claims

Showing the Earth is a globe


  • Sean Lock on Scientists

    What is a scientist? Just someone who thinks about stuff, then chooses to back up their thoughts with evidence and facts. Only difference between me and a scientist? I don’t feel the need. I’m not so insecure I need to back up what I say; I just say it. Naaah!

    Flerfs have a hard time finding any sources that support their claims. This leads to ‘cherry picking’ sections of text from other sources; without fail they remove context and misrepresent the authors of these sources. See also Toon’s law of Flerf #1 .

    One of the stranger cherry picks is this, from the University of Hawaii, used by “Mr Ghetto Daddy” on YouTube.

    If you can locate the North Star, the angle between the height of the North Star when it reaches its zenith (highest point) in the sky and the horizon indicates your location in degrees latitude1. The North Star is a unique star for navigation in the northern hemisphere because it is located almost directly above the earth’s North Pole (SF Fig. 8.3). At the equator, an observer will see that the North Star is located almost exactly at the horizon. Thus, at the equator, the angle between the horizon and the North Star is zero degrees, indicating the observer is at zero degrees latitude.

    Hard to know were Mr Ghetto Daddy is going with this. The reference to ‘hemisphere’ is ignored, and the reference to Fig 8.3 is removed from his quote. Here is that diagram. Note the rather large distance to Polaris. No wonder as to why he removed the reference.

  • Curved Angles


    Flerf comment of the day:

    you think u can measure an angle from a curved baseline, youre maths skills must be so amazing u think 2 + 2 = 5.

    The rationale behind the flerf chant that “the earth measures flat” is that altitude angles (also known as elevation angles) of celestial objects used in celestial navigation require a flat baseline. They claim that this flat baseline is the surface of the earth.

    Inevitably, any evidence showing the earth’s curvature is dismissed and ignored because of this claim. However, anyone with a rudimentary understanding knows this is false:

  • The Earth is Measured Flat

    Anyone having the unfortunate experience of visiting Nathan Oakley’s YouTube channel will have seen this, or even heard it if they can stomach his bile drenched shows. The phrase is used to stop any conversation about measurement of the Earth; conversations that would otherwise show Flerfs up for the idiots they are.

    Just what do they mean when they say “the Earth measures flat”?

  • Maps are Flat; Therefore the Earth is Flat

    Flerf stupidity knows no bounds. A common claim is that if the earth were a sphere then we’d be using maps printed on curved paper, not flat paper. That they cling to this stupidity and present it as one of their chants shows the level of critical thinking among flat earthers.
