People world wide have been taking photos which seem to prove we live on a flat earth. Buildings, mountains, etc. in the background are visible when they should be obscured under the horizon due to earth’s curvature.
The only explanation for this is that it’s an optical illusion caused by temperature variations bending the light. I’ve devised a simple test for this; I’ve taken photos of the same background mountains (only the peaks of which should be visible) on different days, morning & afternoon to see if conditions really do alter the background image.
If you’re new to the subject of ‘flat earth’ you may be in for a shock. If you’re a flat earther already, this probably won’t come as a shock.
