Why does light bend and what are its exact properties

Perhaps an unknown mechanism is affecting light in a similar way?

You're damn right it's unknown. "Bendy light hypothesis" hasn't provided any mechanism for why light bends. In fact, it only makes sense that it actually bends the way it does in Round Earth Theory - Universal Acceleration would just make it bend downwards.

bubble level?

well, it is different, the air floating on top bends around becuase of the force it exerts.  it goes upwarsds and hence, when upside down, farthest, nearest from its previous location would be the outside

i dont think light works that way

I'm merely pointing out that based on the images I've posted, the light appears to behave much like a bubble level.

Conclusion: Light not only bends, but going across the edge of the world, it winds up on the other size.

Basically this means the earth has spherical geometry, and is continuous from the edges of the map, i.e. it has only one side.


can you think of a shape that matches this description???

Light does not bend up, nor is any such thesis required to substantiate the plain fact that the Earth is flat. Light very specifically bends in a wavy pattern up and down like a wobbly line.

By taking the path and altitude of the sun as given by FET, and calculating where in the sky it should appear at certain times of the day from my location.  I concluded that according to FET, the Sun should never descend below 15 degrees above the horizon from my location.

Also, Perspective would have the Sun shrink to a dot before disappearing.  This doesn't happen, therefore perspective does not cause the sun set.]Also, Perspective would have the Sun shrink to a dot before disappearing.  This doesn't happen, therefore perspective does not cause the sun set.

Apparently you've read neither the Wiki or Earth Not a Globe.

I have read ENAG.

My calculations are a disproof of rowbotham's claims.  His finite vanishing point is a mathematical impossibility.

It, however does not cause the sun to look bigger.  This would imply that light was bending sideways as well as vertically.  While the atmosphere does have a lensing effect, it would only occur vertically, not horizontally.

The headlight example is flawed as the glare does not represent the true angular size of the headlight.  With sufficient filtering, the headlights will appear the correct angular size for their distance

No amount of filtering will reverse the atmosphere's enlarging of distant light sources.

No. The Vanishing Point/Horizon cannot be an infinite distance away from the observer as traditionally taught in Art School. Man cannot see to infinity. Hence, the distance to the Vanishing Point must be finite.

The atmosphere is thicker horizontally than it is vertically. When the sun shines in horizontally its light is passing through much more atmosphere than it is when it is directly overhead. Since the sun's rays are passing through much more atmosphere horizontally, the affect of the atmosphere must be greatest during the mornings and evenings.

Tom, the atmosphere only bends (refracts) light in one direction.  In order for magnification to occur, light needs to bend in two directions.

Man cannot see to infinity, which is why the vanishing point is infinite.  Parallel lines do not meet in any finite distance.  Therefore if they appear to meet in perspective, the point at which they meet is not a finite distance away.  Therefore the vanishing point is not a finite distance.

The only affect the atmosphere can have on light is a downward curve, as the light is entering a denser medium.  There is no sideways bend, which would be required for a sideways exaggeration of the sun's dimension.

My point is that there was no enlarging to begin with.  What you see in the photograph is glare.  Not the actual angular size of the headlight.

Parallel lines may not meet geometrically, but to the observer those parallel lines will reach a point in the distance to where they merge. That point will not be an infinite distance away from the observer; but an artificial finite distance. Man cannot see an infinite distance away.

Please clarify your statements.

When the image of the sun is shining form overhead noon the image is passing through significantly less atmosphere than it does when it is shining horizontally to the observer. This additional atmosphere is the cause for its enlargement.

The headlights are clearly enlarged in the photograph. Any child of five could attest to this.

There are different types of magnification. What you are describing is the magnification which occurs when viewing objects through a magnifying glass.

This is not what occurs on the atmosphere. The atmosphere magnifies bodies through the projection method of magnification. An image of the sun is being projected upon the atmosphere between the observer and sun.

Have you ever noticed that if you hold a body far from a magnifying glass that the image will flip upside down? When you move the object past the glass' focal point it flips.

In contradiction, if you shine a projector at a surface of a wall the image will not flip no matter how far you are from the wall. The projection method of magnification has no focal point beyond which al bodies flip upside down.
