Crepuscular rays
I don't buy the flat earth view but there is one argument that I cannot find a satisfying explination for. Crepuscular rays.
They claim these rays ought to be vertical and parallel (as I also envisage) but that their angled rays show that the sun is not far from us. A few demonstrations are presented in the final clip Im posting.
The best explination, from what I found, relies on optical perspective and always shows a picture of train tracks. (Can't seem to paste pictures. Any tips?)
Im yet to find a demonstration of this. I've seen animations trying to apply this to crepuscular rays unconvincingly, such as this animation which at 0:37 tries to show parallel lines when in fact their not. The animation is also missing the most common view of seeing these rays from a distance
https://www.youtube.com/watch?v=cTPLqbl-HGY
Their counter argument is that vertical objects such as the fence posts in the train track picture do not converge up at angles, they still appear vertical.
This clip explains their point well although I don't totally agree with his explination of light at the end.
https://www.youtube.com/watch?v=QkhY8k9t9Fs
Can anyone refute this? Preferably by giving an example or demonstration.
Or does anyone have any thoughts on crepuscular rays?
Again... Flat earth is not something I believe and Im not arguing their view. So save the finger pointing and name calling again.
These are not complaints. These are questions as I find this phenomena interesting and would like to understand it more.

Re: Crepuscular rays
Now thats better. Apart from the rude ending see how helpful and informative you were. Much appreciated.
I didn't find your previous posts informative or helpful. They were just rants and false claims of creationist despite explaining my upbringing and position.
Very frustrating. I never used religion as a defence.
Besides my question about early and pre primate evolution wasn't so silly for someone who is admittedly uneducated on ToE.
It led to conversation between members over the finer details of early and pre primate evolution.

Re: Crepuscular rays
All your questions are answered in the link i provided including practical demonstrations.
https://www.youtube.com/watch?v=QkhY8k9t9Fs
Some kind of example or demonstration using an alternate light source as they have done would be ideal.

Re: Crepuscular rays

Do you understand why the fence posts don't seem to converge?
Because they are perpendicular to the observer as in this picture
The buildings remain plumb. They do not converge like the rays of the sun are.
But like I said b4 to someone. All of this is on the link i posted with an experiment using an alternate light source and a demonstration using street lights which support thier view of a close sun.

Watch it first at least so you understand their evidence in order to properly try to explain it. Remember im not making the argument, they are.
If there was a tower on the right and a tower on the left which way would their shadows be cast?

ARE the crepuscular rays perpendicular to the observer ? It sure doesn't look like it in your picture with the buildings?
The crepuscular rays don't appear perpendicular to the observer but they are in fact perpendicular from what I understand. Or parallel at least

As for the experiment I'll just point out that false assumptions about the conditions will lead to false conclusions
Can you please elaborate on what exactly is being assumed?
And why can't we replicate this in an experiment? Shouldn't we be able to demonstrate that?

Well, dissmissing or criticising an experiment without even viewing it is hardly objective is it. In fact its an assumption in itself.
I listened to the arguments presented by these flat earth believers. (objectively as I could given I thought this idea was ludacris) One by one i dissmissed all the evidence and their whole view.
But this one argument they present regarding crepuscular rays, the experiment and examples they give against the "perspective" explination is a very good one.
I'm yet to find a decent counter for it.
And even if we simply dissmiss their evidence as garbage or whatever I don't think perspective can account for such a wide spread of rays covering almost 180 degrees as shown here

The rays are heading straight for the observer
Thats not possible in the last picture I posted as the sun is beyond the horizon.
Perhaps you missed it...
Again... This is their view not mine. Im just trying to understand, not debunk.
Ur just dissmissing or arguing against something u haven't even seen yet.
Can someone please add something constructive

don't even try to address the question
What question?
What is wrong with the first experiment? Why is this perspective not present?
Why can't we replicate it?

Re: Crepuscular rays
Your point was...
quote:
The rays are heading straight for the observer
The rays in the picture are not heading straight for the observer at all.
U dissmissed the question before seeing it. U then dissmiss the experiment and examples without any explination. Obviously ur here for one thing only which is not what im here for
Hope someone can add something intelligent to this conversation cos this condescending attitude is far from helpful or constructive

Re: Crepuscular rays
According to google its 149.6 million km.
Please everyone read my original post on this.
Cos if your just looking to be condescending I never refuted anything.
Id appreciate it if people adressed the points made in the original post and be helpful.

Re: Crepuscular rays

There is no silver bullet
What silver bullet? Oh i know, that bullet. Their trying to shoot you. Your trying to shoot them. Its a war. Both sides just looking to shoot each other.
U didn't bother to read my original post.
So far no one has helped me understand anything apart from this stupid war.
The best answer to my own question is provided by myself in the 2nd link of my first post. Which not surprisingly went unoticed.
Im totally aware that mathematics supports our knowledge of the suns distance. I trust mathematics. Debates are rare compared to the metaphysical fields of science.
I simply asked if there was an example or demonstration we can observe which supports visiual perspective of crepuscular rays. And basically asked for help visually applying the perspective I recognise in engineering to the dynamic physics of light from the sun. Instead I get pre conceived condescending arguments and get responses like...
"It wouldn't negate everything else we know. There is no silver bullet" Not what I said
And "The dismissal of perspective is just plain wrong" Not what I said either
Seeing im getting no where here and cannot find such an experiment where this can be observed im just going to go into a drafting program and animate it in 3D.
See if that helps me visualize it.
Why do I even bother with such single mindedness.
Its clear this is just a war which I don't belong.
