##### Why crepuscular rays aren't proof for the position of the Sun.
« on: May 01, 2019, 12:59:52 PM »

Let's ignore the mainstream-science explanation for crepuscular rays with light-scattering and perspective.
https://en.wikipedia.org/wiki/Crepuscular_rays
Let us ignore that. Let's instead assume that what we see with our unaided eyes were true: That the rays emanate DIRECTLY from a light-source.

You cannot use the angles of the crepuscular rays to deduce the position of the Sun, because you don't know how far away the cloud is.

A simple experiment to demonstrate my geometric argument:
Shine a light on a wall. In front of the light hold a piece of paper, so you can see its shadow. (Or just hold a paper in front of your face and squint your eyes.) Hold the paper in such a way that a corner points up.
If you hold the paper upright, the shadow of the corner has the same angle as the corner. 90°
Now, as you tilt the paper, the angle of the shadow of the corner gets bigger and bigger than 90°, even though the corner still has 90°.

My point is: What you see in the crepuscular rays is not an upright triangle. You see a tilted triangle and you have no idea how far away the top corner is. From the crepuscular rays you could deduce the vector from the position of your eye to the position of the source of light, but you don't know where on that line the source of light is.

Now, if we were to triangulate the directions of crepuscular rays from several positions on Earth, THEN we could calculate where the top corner of the triangle is, but a single observer cannot measure the tilt of the triangle. He sees only the projection of the triangle.

Therefore, observing crepuscular rays as shown in the image above is no proof for the distance of the Sun or for Flat Earth.

Light travels in straight lines. Parallel lines if from a source infinitely far away.

If you can't just follow those lines and complete the triangle, round earth needs to explain why this light bends. This distance of the clouds is not important. That distance is small compared to the millions of miles the sun is purportedly supposed to be.

If ever with your eyes you want proof that the sun is not millions of miles away, your picture is an excellent example.

The light doesn't bend.  Perspective says that parallel lines appear to converge in the distance, even though they never actually get any closer together.  Crepuscular rays are akin to an artistic technique known as foreshortening.

Science is what happens when preconception meets verification.

If you can't demonstrate it, then you shouldn't believe it.

Crepuscular rays have been discussed many times before. I don't know why Thork is taking the stance he is, it's well known tracing the ray paths back doesn't work for RE OR FE sun height claims. Here's a good post with info on things.

Yes, "crepuscular" is the search term which will give you some results.

Meanwhile a have a similar "grounded" example for you, not so striking, as the length of the field is limited.

Reason is: Perspective.

The rays are practically parallel due to Sun being very far. Here is a very simple explanation: http://www.atoptics.co.uk/atoptics/rayform.htm

Thank you both. The explanation makes perfect sense for either FE/RE. I like the picture of the rows of heather (or whatever it is). That is a good way to visualize and understand the perspective.

I keep on hearing that train tracks are parallel but look at this!

If ever with your eyes you want proof that train tracks meet, this picture is an excellent example.
I always find it weird that FE use perspective wrongly to try and explain sunsets but then forget perspective exists when thinking about pictures like this.

And the angle of those tracks is less pronounced than those sun rays. Those rays are at a greater angle than one can attribute to fore shortening.

What is your basis for that claim?
If in my image you changed the position of the camera it would change the apparent angle. If you point it straight down at the tracks then you see them as they truly are, parallel. The angle at which they appear to converge changes as you move the camera.
If you knew your camera position and angle in relation to the tracks and the distance the tracks are apart then you could work out the apparent angle. I don't believe you have sufficient information from that image to make the claim you are making.

If the angle in that picture was caused by reality rather than perspective then the sun would be just above the clouds, we know that is not true even in your model.

But, but, but what about anticrepuscular rays?

https://en.wikipedia.org/wiki/Anticrepuscular_rays

How does the light bend one way and then the other next? OBVIOUSLY, it has nothing to do with the distance to the sun, and all about perspective. You can't change the laws of physics to bend light one way and then the next just by looking the other way.

Thork may be correct. The further the straight lines originate from you, the more parallel they should appear to each other. Go to https://www.tinkercad.com and zoom out from the standard workplane.

False equivalency, Tom. Using CAD for perspective compared to what we see in the real world? I don't think so.

Considering video game perspective is already mentioned on the wiki, what did you expect him to invoke?

The same effect is found on a 3D video game which assumes a flat surface. When you increase your altitude you can see farther because you are so much higher than everything else. Your computer's resolution is better able to see something below you than off on the horizon where the pixels are linearly squished.

We are smarter than those scientists.
I see multiple contradicting explanations. You guys should have a pow-wow and figure out how your model works.

Star Citizen or No Mans Sky both look pretty flat from the ground on planets though so not really sure why that entry is there.

Thork may be correct. The further the straight lines originate from you, the more parallel they should appear to each other.

If lines are parallel then they're parallel. How far they originate from is irrelevant. Although in this case it is the distance they come from - a distant sun - which makes them so close to being parallel that we can treat them as parallel.

But the key error in your post is
the more parallel they should appear to each other.

The way things appear and the way they really are may be different.
The rays from the sun are (effectively) parallel
Train tracks are parallel.
But how they appear depends on your perspective.

If you look straight down at train tracks then you will see them parallel which is the reality. If you look at an angle then you will see them appear to converge as in my picture. The angle they converge at depends on the angle you're looking at them. That is perspective.
I can't explain it any better than that video above but this is another example of you just not understanding perspective. You use it to explain sunset (which it can't) but then misunderstand it when it comes to explaining crepuscular rays (which it can, as that video shows).

Sorry, that is not a true statement.

Photons are projected from the Sun in all directions, each form a straight line. The ones projected at 30° from each other will not appear parallel, even being the Sun very far away.  I am stating here the "observer view aperture", not distance.

I can have a small 0.2" LED projecting photons at 2cm of distance, entering a micron slit between two separated sets of two blades and obtaining extremely parallel photons. This is a very common optical lab setup for filtering narrow parallel frequency bands, in some chromatography experiments.

The "parallel rays" appearance depends greatly on the observer view aperture, distance from the source is a secondary variable and can even be discarded.

Tom, are we to take this to mean that you support straight-line paths of light from the Sun?

Baby Thork, the original post picture of the rays could not be used to verify the distance of the sun whether it is 93,000,000 miles or 3000 miles (however far it is in the flat Earth model) the way those ray converge would put the sun just above the clouds where planes would run into it.

The post with the sun behind the tree would put the sun like 5 feet on the other side of the tree.
It could be round or flat, but round has really been working out so much better for us.

Perhaps it would be better to say the Earth is "pointy".
