Does the Coriolis Force on airplanes flying North prove the Globe is impossible? This is almost a shaggy dog story so I'll spoil the ending here for the tl;dr -- it acts like something between gentle breeze to a stiff wind, is corrected the same way, and there is pretty much no net effect as it is constantly countered by holding the heading steady. What is the Coriolis Force? Very simply stated, it is an apparent force (not a Proper Force that we measure as an acceleration on a mass) caused by inertia in a rotating reference frame. The simple example is you are on a merry-go-round and throw a ball towards the center, it appears to be deflected. But from the point of view of someone NOT on the merry-go-round the ball goes in a straight-line once you release it.  So that's why it's not a Proper Force. Translating that to a globe, if you are on the Equator you have an Eastward velocity of about 464.9 m/s (or 1040 mph).  As you move North in an airplane you retain this initial...

Another COMPLETELY dishonest Flat Earther video -- call me shocked. Once again, they completely IGNORE the height of the observer. QUOTE: curvature drop (H) = 8 inches * d * d = 8 * 6.95 * 6,95 = 386.85 inches = 32 feet (9.5 meters) Where did they demonstrate an accurate height of the camera above the water? For that to be accurate that camera lens has to be half-way under the water so the center of the lens is EXACTLY at zero elevation.  Any higher than that and they are lying to you. Oh there it is -- the camera is well above the water...  I estimate about 4 feet above the water level. So what DO we end up seeing?  Do we see the shore of the 6.95 mile away beach? No, we some typical blurry as all hell P900 footage where we can *maybe* barely make out the top of the rock wall.  Why do Flat Earthers refuse to buy a good camera? So Let's see what that view looks like up closer.  What I did was mark a 3D line in Google Earth Pro from their claimed observer locatio...

Many Flat Earthers will post this meme: @NASA 's photo is the one on top... The one on the bottom is the result of an investigative photo analysis; which proved @NASA 's fakery... pic.twitter.com/tT1uisIL8G — BeautifulFlatEarth (@etasio) July 27, 2017 Which is, of course, a complete and utter fraud and lie on the part of Flat Earthers. The meme features a squashed and cropped version of this image of Buzz Aldrin coming down the ladder of Apollo 11 in frame  AS11-40-5868 : Flat Earth liars have purposefully extended the frame and added in the picture of the Earth. Now, WHO is lying to you? The ever astute @FlatSlugBrains also pointed out that it would be impossible for the Earth to appear that low in the sky from the Apollo landing sites (any of them, much less Apollo 11).  This wasn't obvious to me at first but it is a logical consequence of the Moon being tidally locked to the Earth, the position of the Earth in the sky doesn't change much on the Moon!  It wobbles a...

To answer this  I grabbed one of the DISCOVR/EPIC frames  epic_1b_20170726023808_02  and I found that the Earth was approximately 1506 pixels wide -- this is the semi-major (a) axis: Next, we need to calculate how tall we would expect the Earth Ellipsoid to be IF it wasn't a perfect circle.  To do this we get the model value from what is called WGS-84 (World Geodetic System from 1984) , which is the current measured values for Earth.  It defines the measured semi-major axis (a) and something called 'flattening', using this you can calculate the semi-minor axis (b) using a simple equation that defines this relationship for an ellipse: ƒ = (a − b)/a Therefore, b = a - aƒ From WGS-84 we have: 1/ƒ = 298.257223563 Therefore, ƒ = 1/298.257223563 So given our semi-major axis (a) is 1506 pixels wide we would expect our semi-minor axis (b) to be approximately: b = 1506 - (1506  × (1/298.257223563)) ~ 1501 pixels And that is what we find, to within 1 pixel...

​ What do rockets 'push off of''? You gotta be kidding me right?  We learned this stuff in 10th grade. The short answer is 'the same thing as everything else, mass'. Flat Earthers will often cite an airplane as "pushing off the air" but this is simply not true.  They do PUSH THE AIR itself, but not OFF of it.  When the airplane propeller blades hit air molecules two forces are produced, one pushes the air backwards and the other pushes the airplane forward -- these are EQUAL and opposite forces.  It is the fact that the airplane has imparted a Force unto the air molecules in one direction that it is PUSHED in the other by this very action. Neither do submarines "push off" the water, their propellers hit the water and there are two resulting forces -- one pushes the water back and the other pushes the submarine forward. Let's talk about Newton's 3rd Law -- ALL PROPER FORCES occur in equal and opposite pairs. And here is a simple experiment...

Flat Earth'ers frequently post extracts from this 'Little Piggy' video series and claim #1 that the video isn't distorted, and #2 that it's proof the Earth horizon is 'flat' at 120,000 feet.  #CheckMate Ba'al worshippers! 121,000 feet & still flat. The horizon would be fading downward on a globe, but it don't. Video proves everything NASA says is a lie! pic.twitter.com/mhrTuECAQm — Gospel Truth (@BadBuc99) July 26, 2017 and pic.twitter.com/CYmN46DjPQ — Michael Davino (@davino1959) July 3, 2017 Um... Original uncut video is broken into many parts, starting with part 1 ( playlist ): First of all, we can see very clearly this IS a fisheye lens: Ok -- so that means all the images are distorted as per the curvilinear distortion field: This is why the horizon bows down here -- it is below lens center (technically everything is squished in towards center to make room to "see more stuff"). ONLY along the horizontal lens center will the vertica...

Red Bull Stratos jump proves Flat Earth? Oh really? One Flat Meme claims it's "Planet New Mexico" -- because they do not understand the geometry of the horizon on a spheroid: EVERY TIME you examine these claims you find the same thing -- the view actually comports with the Globe model and NOT the Flat Earth model. Another yokel on YouTube claims the interior view shows the "horizon at eye-level". Here is "eye-level" being MEASURED by me from a plane at two different altitudes and also by a professional geodetic surveyor, marking out level from his position on Apple Pie Hill . But you know, this genius can just LOOK at a picture and find where "eye-level" is -- because he's a LIAR who just claims that "eye-level" is magically where ever the horizon is I suppose... and his EVIDENCE is... the horizon is at "eye-level" because the horizon is at "eye-level"... No measurement, no nothing!  Just a bald assertion....

Our favorite Aussie pilot and Flat Earth debunker Wolfie6020 posted this video of the Sunset using his Thousand Oaks solar filter . Which was then forwarded back to ME via a Flat Earther claiming this is proof the Sun shrinks at sunset. So I grabbed the first, random middle, and frame before it starts setting and sized them up: So three clear observations: #1 it clearly does shrink VERTICALLY (as predicted by refraction) #2 it equally clearly does NOT shrink in the HORIZONTAL. #3 it clearly disappears bottom first, leaving the width intact and slips below the horizon, this is NOT an effect of perspective. If this was 'Perspective' it would shrink equally in both directions.  That right there thoroughly debunks this claim (as I showed in Perspective For Flat Earthers ). However, this is a known phenomena ( Flattened Sun  and ATY's pages ) where light from the upper rim is refracted slightly less than the light from the lower rim -- since the light paths go through different ...

First of all... this is the STUPIDEST argument in the history of all arguments because Flat Earth usually has neither Space, nor objects moving around IN Space (lacking Space to start with) and the Flat Earth would have to be both MUCH LARGER and MUCH CLOSER to the Moon. Aside from the complete stupidity of this line of argument... #1 lunar rotation hasn't always been tidally locked - many craters are from before this happened #2 the gravity of the Earth would curve the path of any incoming objects -- even a TINY deflection would suffice #3 The Moon is (almost) 1/4th the size of the Earth but is ~30 Earth diameters away! This means the Earth covers ONLY 2 ° of the sky from the Moon (the Moon is 1/2 ° in our sky). #4 as you can see very clearly in high magnification Lunar videos (even the  one I posted ) the surface of the Moon is curved - only one point is directly facing the Earth at any moment and thanks to  Lunar Libration  (go look it up) that point isn't even constan...

Sometimes Flat Earthers will deny that the Moon causes Solar Eclipses. Here some some eclipse images from the aptly nicknamed "Mr. Eclipse", aka F. Espenak that pretty soundly trounce that argument. 2005 Eclipse Image Credit: F. Espenak 2006 Eclipse Image Credit:  F. Espenak 2008 Eclipse Image Credit:  F. Espenak
