Proof the Horizon is Curving Up? Using oceanfront high-rise buildings to prove earth is concave

One can easily confirm earth is concave using this method.

The idea is this : Using simple observation and a few extra key factors, one can for sure logically be forced to deny that the earth is curving downwards, and rather actually curving upwards.

The few key variables here include

  • An observer in a high rise building
  • There are other high rise buildings in the field of view to be used as reference and markers for how high up things actually are. For example, we can use as reference levels of a building for an approximation of altitude.
  • Preferably oceanfront or near oceanfront view. This is very important because we will be utilizing water to help eliminate topographical errors knowing the behavior of water.

Any observer, standing on any floor of a high rise building and looking out, will be seeing a horizon that appears to be roughly at the same altitude as the observer’s line of sight. In these examples, we can simply use the altitude/level in which the horizon intersects the buildings, and using the building’s floors as a marker for how high the horizon is. (…more below)

The horizon in the picture below (…continued below)

The horizon can clearly be observered to be at around the same level as the observer. THe observer can be seen to be in a high rise building. Using the other buildings infront of the observer, we can see they are atleast 20+ floors up. The horizon appears to rise this high and is directly infront of the observer. If the observer were to point at it, they would be pointing ABOVE many buildings infront of them. This is a major issue for Convex/Globe earth, because this is NOT in accordance to what is required for a convex/globe earth.

In a theoretical convex earth, the observer/reference from would be at the HIGHEST POINT on the earth, and have the earth curving DOWN AND AWAY from them in all directions.

In a theoretical concave earth, the observer/reference frame would be at the LOWEST POINT in the earth, and have the earth curving UP and AWAY from them in all directions.

We ask the reader to please now, having the above in consideration, to look at the rest of these observations incorporating some of the variables and explanations shared above.

Another helpful tip.

In a Convex/Globe earth, buildings further away from the observer should be AT A LOWER ALTITUDE and FOUNDATIONALLY (Base of Building) lower than the Base level of the building that the observer is in, relative to their reference frame.

In a Concave earth, buildings further away from you are actually RISING UP / at a higher elevation of foundation/base (relative to the reference frame/observer)

Using the above two situations and the pictures we observer, we can actually confirm EARTH IS CONCAVE because : The observer’s direct line of sight to buildings far away, they are looking at a lower floor of the building than the building they are in. If earth was convex, they should be pointing to (line of site) at a HIGHER FLOOR of the building than that which they themselves are in.

It remains clear –
The buildings used as markers and reference points PROVE the horizon is curving up and not down

It remains clear – THE HORIZON IS TOO HIGH

I don’t understand. If light is bending up we will never see concave surface with visible spectrum. Light is like renderer for the eyes.

“In a theoretical convex earth, the observer/reference from would be at the HIGHEST POINT on the earth, and have the earth curving DOWN AND AWAY from them in all directions.”

“DOWN AND AWAY” . Here is a point because in concave earth that LIGHT travels AWAY from the surface. This makes illusion like it surface goes DOWN. That’s why obserwations based on light cannot proove anything, because you can fit them the same as to convex and concave earth.

One thing you can measure with towers is make impulse wave and detector on roofs and ground floors. But its almost impossible because of range needed and incredible precision of detector measurment.

That’s an interesting take on the subject. I have a couple of things to offer here for your consideration.

As a photographer for over 50 years, I understand that the format and lens make all the difference in the world when it comes to perspective. In a full frame slr or dslr camera (35mm format on film), 57mm is almost exactly what the eye sees. Longer than that flattens the image (pincusion distortion), shorter lens lengths do the opposite (barrel distortion). This is why portraits are usually taken with 80mm-135mm lenses, as it makes noses look less pronounced and flattens the face somewhat. Wide angle lenses make things rounder, think fish-eye lens.

So without knowing these two parameters, lens length and the size of the sensor, it’s difficult to know if the proportions are the same as what we would see in real life. Wide angle lenses are often used to capture large areas, but the proportions will be off, thus affecting the perspective. It’s how one would make a curve appear. Think Go Pro cameras on balloons. As they move up, a concave curve appears on the horizon, and when moved down, a convex curve appears. Neither represents reality. Using a long lens will also affect the proportions. That’s how photographers make the sun and moon look extra large in cityscapes.

Also, perspective is often altered using tilt-shift lenses or in processing engines like photoshop through perspective manipulation. Your first image appears to have been perspective corrected in photoshop or another processing program.

The image with the two chairs on the balcony is clearly a very wide lens. You can tell this by looking at how the high rise buildings near the sides of the image tilt away compared to the ones in the center of the image. Can you see the difference? Because of this, there is no way to see the proper perspective.

I find it impossible to see any curvature with a normal lens. It’s simply too big of a curve to see with such a narrow view (only about 35 degrees). Either with a camera or our eyes. But, we can tell sometimes by looking front to back if we have markers or lines to follow in the foreground.

Also, many people fail to realize that the horizon is not a line, this is a misnomer. The horizon is an arc. Your two eyes focus together at the furthest visible point, and as you pan left or right without moving your eye focus, the sides of your vision will be physically closer. Simply turning in a circle should confirm this in you mind. You end up drawing a circle!

When it comes to our vision, the eyes can deceive us as well, even if we have perfect 20/20 vision. Cones and rods don’t see the same. And we also have a blind spot near the center of our vision where the optic nerves connect. Our brains fill in this spot, much like photoshop does. This is why we can’t really trust our eyes. What we see is always partially made up in our brains.

As far as where the horizon sits in the image, this is a factor of the pitch angle of the camera and how high it is set above the ground in addition to the lens parameters mentioned before.

My point is, using photographs to try to see curvature is very difficult, maybe not possible at all. That is unless you know all the parameters in the image. If you can control all of these parameters by using the right lens and perfectly stitching multiple images into a panorama, perhaps you can see a real difference. But I think front to back rather than side to side is the only way possible.

This was not intended to discourage you in any way, rather just to let you know what you are up against both in photography and natural human vision when determining perspective.

I’ve run into many brick walls trying to find proof for this theory, but it is out there. There is no doubt in my mind that we live inside. Trying to prove it to others can be very challenging. It’s easier to falsify the other theories than to prove this one, and that has been done through experiment and observation. So just by the process of falsification, the concave earth theory stands alone. There have been two observational and one mathematical experiment that I find 100% convincing on showing the world is a concave sphere. But that doesn’t mean others will agree. So I’m always searching for more.
