Flat Earth Follies: a curve cannot reflect a line/column of light

Several Flat Eathers now have tried to claim that a 'column of light' cannot possibly form on a convexly curved Earth - which is just ridiculous but here we go… all will become clear.

This one I personally took on a sharply convexly curved overpass. Clear columning is observed along the convexly curved surface.



Here we observe it with sunlight all the way over the very clearly convexly curved wave!


And here is a diagram showing why.


And we don't see the full column when the water isn't rippled enough.


It's all about the angles, nothing what-so-ever to do with overall curvature or shape of the Earth.

Conclusive enough?

No, the guy just kept denying and making excuses. Anyone want to try to make a coherent argument against this?

Pic Gaspard (3880m)/Grand Ferrand (2758m) from Pic de Finestrelles (2826m) in the Pyrénées

I have some new toys to share in this installment of 'Yes, the Earth really is Curved even though you can see one distant mountain peak from another', so this should be fun! This time we're going to look at a view of two distant mountains from Pic de Finestrelles (2826m) in the Pyrénées , taken by Marc Bret of Beyond Horizons (see also the Flickr album ). Pic Gaspard (3880m) in the Massif des Écrins range at a distance of 443 km. Grand Ferrand (2758m) at a distance of 392.48 km. Our view is right around 42.414466°N, 2.132839°E at about 2826 meters elevation, looking right along the coast. Pic Gaspard/Grand Ferrand from Pic de Finestrelles in the Pyrénées, image by Marc Bret The EXIF metadata shows this image was taken by a Panasonic DMC-FZ72 with a focal length of 215mm -- given the 5.62 crop factor of the 1/2.3" sensor in this camera, this gives you a 35mm equivalent focal length of 1200mm giving a full frame view of 1.644° wide and 1.215° high. Since 1521 x 101...

Flat Earth Follies: Planes would have to constantly pitch down to fly!

Image
Flat Earth Claim Planes would have to constantly pitch down to fly! Short Version In the Globe model "LEVEL" follows a sphere of uniform gravity potential. Feel free to disprove that is the case if you can but that is the model. In an airplane, Elevator Trim simply controls the RATE of pitch of an aircraft - not the actual pitch of the plane. A 747 flying at 35,000' would have a flight circumference of  about 2π*(3959+(35000/5280)) ≈ 24916 miles Flying at 570 miles per hour, this plane would fly a fraction of the 360° around given by 360*570/24916 Since that's 1 hour we can divide by 60 to get the degrees per hour: 360*570/24916/60 ≈ 0.137°/minute That is down in the noise since pitch rate is affected by temperature, density, power, and control settings on the plane you simply trim the plane for as close to ZERO vertical speed as you can and you've automatically compensated for all of them at once.  Of course, on a 747 computers do that.  In a small plane the pitc...

Fort Myers to Naples - Flat Earth failures continue

Image
No amount of curvature is enough for a Flat Earther.  We can SEE the shoreline disappear, and then the bottoms of buildings.  But since they don't understand the geometry of what they see they cannot properly evaluate it. Flat Earth once again fails to understand WHAT the horizon even is. @captscorch @ColdDimSum @nicholaspitts @CobraElDiablo @UnCastellsMes @twatterfull @sciencegecko @skeptropolis @FlatEarthReal Still waiting on my curve pic.twitter.com/zh2zFXmMVi — JACK (@Adidas68Jack) April 24, 2017 And a copy of the image from Jack just in case (which Jack now deleted). I'm going to admit right here at the start that I do not know the EXACT location from which this photo was taken.  Neither does 'Jack'.  However, we both know the APPROXIMATE location to within a few miles because we can see the nearby buildings and at least their rough orientation. But without a higher resolution image I cannot positively identify the distant buildings, and neither can Ja...
