On google earth, you can see images of every land mass on the planet. You can compare these images to reality, by looking at places you have been too or photographed. You can also measure distances.
Now if the Earth is flat, then to fit the continents to the globe, they would have to distort the images, ones at the edges of continents would be compressed radially from the centre. Try pressing a bit of paper onto the surface of a ball to see how it would distort.
So the Google Flat Earth Challenge is to find an example of such a distortion.
Things to look for:
Kinks in rivers and roads
incorrect distances
missing bits of land
curvature of straight features,
anything that is different to ground level observation (post pic from ground level)
Rules:
Post screenshot and coordinates
No discussing, if you think there's a falacy in the premise of the challenge, make a new thread,
Explain the distortion and the actual appearance, post a pic of the location from ground level if you can.
Distance discrepancies must be compared to an accurate map.
No low rez zoomed out distortions, of course it's not accurate, it's low rez. and yes we all see the arctic region looks funny in low rez.
No beech width differences, they are caused by tides,
No colour differences, its a different day dumbass, you need shape discrepancies.
No Antarctic centre stuff. Its low rez coz no-one cares, and you've never been there anyway.
Now go out and find evidence of conspiracy,
