Introduction

Dear Visitors,                                                                                                                                    April 21, 2017

Thank you for stopping at FlatEarthLunacy.com

As a scientist with college degree in Astronomy, minor in Physics and Mathematics, I was appalled to find folks telling outright falsities and presenting bad science to bolster suspicion of our known accepted reality - that the Earth is a beautiful blue globe.

This blog clearly shows scientific proofs that debunk everything that flat Earth proponents claim.  Here we also expose the comments those YouTube video channels delete, because they don't want you to see them.

The Earth is not flat.  That claim is a conspiracy theory perpetrated by ignorant people who have ulterior personal motives and agendas.

The Earth is a beautiful blue spheroid globe spinning on an axis 23.5° once each day, and orbiting the Sun every 365.25 days.

Flat Earth NOT - Where is the curvature?  Where is the curvature?

Written by Super User. Posted in Uncategorised


Dear Readers,   

The curvature is always right in front of your nose.  You just need to look and understand.

                                                                                      Summary

1.  Wherever you stand on the Earth, the surface in front of you AND past your observable horizon, is Earth curvature.

2.  Wherever you stand above the Earth's surface, turn around in a 360-degree circle and some oblique curvature of the horizon will be visible.

3.  Earth curvature can be directly seen during a total lunar eclipse, as the result of various physics experiments, and photography from space based satellite systems.

1.  Wherever you stand on the Earth, the surface in front of you AND past your observable horizon, is Earth curvature.  It curves down away from you, and what's over the horizon is hidden.  But you can see it by moving to a higher position above the surface, or sighting an object (ie., boat, building, etc.) and noticing that the bottom portion is missing.

Say for example your eyes are 5-feet above the ground.  Because we live on a sphere, the distance to your horizon is 2.7-miles.  In that distance, there is a horizon bulge (the curvature of the Earth's surface that limits the range of direct line-of-sight) of 1.22-feet.  An object sitting on the ground at distance 2.7-miles is fully visible, from top to bottom.  But you need to look down at an angle of 0.040-degrees to see your horizon line.

All land or water objects past that 2.7-mile horizon is not visible, as it curves down away from your line if sight - unless of course a structure is taller than the Earth curvature at that point. 

Got it?  It's all there.  You just need to know how to look.

Earth curvature is always with us.  But because we are so small and the Earth is so big, the curvature from our human frame of reference on the ground is very very tiny - BUT IT DOES EXIST

So here is the measured Earth curvature angle with respect to our tiny view:
Even a tiny glass of water on a table has curvature = 0.0000006288 of a single degree
Gold fish bowl = 0.0000022457 of a single degree
Back yard above ground swimming pool = 0.00000269485 of a single degree
Olympic size swimming pool = 0.0004491429 of a single degree
At 482.727 cm from the water line at the beach = 0.0433556196 of a single degree curving down away from you

2.  Wherever you stand above the Earth's surface, turn around in a 360-degree circle and some oblique curvature of the horizon will be visible.

What people usually mean by “see the curvature of the Earth” is actually a misnomer.  They are actually seeing their horizon curve around then and no the curvature of the Earth.  Of course, your horizon is a product of the curvature of the Earth, but it’s technically an indirect observation.

You can see the curvature of your horizon on Earth at ANY altitude - just by noting that your horizon curves around behind you. Even at hundreds of miles above the Earth you are still only seeing the curve of this horizon, it just becomes a little easier to see it as a circle as you get higher. This is not literally the same as seeing the curvature of the Earth. Doing that is more difficult because the curvature is very slight until you get great distances away (at which point the features of the Earth are very small) and the greatest curvature is always very oblique to our viewpoint along the edge.

From just 200 meters’ elevation, on a 4000-pixel wide image at 94.4 degree field of view you should expect about 7 vertical pixels of rise out of the horizon circle (as shown in my calculator link). You can make this slight ‘bump’ more visible by compressing the width of the image to about 10% of the original width and stretching it vertically by a factor of 2–4x.

For example, if we do this to the image here (which also required slight rotation):

Going to the stratosphere...


   2018-03-25_00-13-13.png

Earth curvature from the stratosphere:

at 10-km height above the Earth’s surface = 3.2-degrees

at 20-km height above the Earth’s surface = 4.5-degrees

at 30-km height above the Earth’s surface = 5.6-degrees

at 40-km height above the Earth’s surface = 6.4-degrees

at 50-km height above the Earth’s surface = 7.2-degrees

The curvature is not readily to be seen by looking around left or right, in a 360-degree circle, unless you have a very wide angle panoramic view.  Generally at ground level your eyes will not see it.  That circle is your line of sight to the horizon.

But instead, look directly out in front of you to the horizon.  For the first half of that distance the ground raises up (the bulge) and for the 2nd half of that distance the ground curves downward away from you.  It's the downward slope of the ground AWAY FROM YOU that we commonly call earth curvature.  

The curvature is the Earth's surface slope down away from you, past the horizon.  And since it slopes down out-of-sight, we need to do something else to see it more clearly.
