Horizon rises as altitude is gained

When you are traveling in an airplane and look out the window you see the horizon rising up to your level of view. This is what one would expect on a flat or a globe earth. It is due to perspective. We see the sun rising from and setting at the horizon also and flat earthers claim the sun is rising and setting due to perspective. Which could be the case. So in the case of the sun they are happy to accept it, which they claim is about 8000 miles up, coming down to the horizon, yet they are surprised the horizon comes up to their eye level when they are only about 10 miles up in the air.

As we go up we have to expect the horizon line, which is due to perspective, will sill be at our level. This is the expected behavior either on a globe of 8,000 miles in diameter or on a flat plane.

We can only rise up such a small distance relative to the size of the earth. So in this small distance the horizon will behave as it always does according to the laws of perspective.

If the earth is a globe then if we could rise up high enough we would be able to see the edges of the globe, but this would certainly not be possible at 10 or 20 miles up.

This is not proof the earth is flat. This is the behavior we would expect rising up from a globe of 8000 miles in diameter or rising up from a flat plane.


Supporting Flat Earth Proofs

  • 2) The horizon always rises to the eye level of the observer as altitude is gained, so you never have to look down to see it.

    This is way too advanced a study. Ship’s sail goes down over the curvature at about 13-15 miles away. Ship starts laying over too.

      And then, while watching the ship disappear, you bring out telephoto lens or binoculars and ship appears again. Explain that to me please. Thank you
