If this is the first time you are watching
my video; well, welcome dear viewer. This
is a series where I take a look at one of
the Flat-earth flyer, and discuss/debunk one
section at a time.
So far, we covered “Water is a natural level”,
“Airplane level flights”, “Science says
it’s stationary”, “Horizon is always
Eye level”, “We see too far”, “Dome
is Real” and “Moonlight is Cold”.
This video is all about Crepuscular Sunrays.
The sun is smaller than earth and very close.
We can trace the angle of rays back to their
source above the clouds. The sun is clearly
not massive or 93 million miles away, but
small and relatively close.
Now I always try to see things from the other
person’s point of view; but I still can’t
figure out how this is a proof of flat-earth.
Anyway, I digress.
Let’s ignore everything else that is wrong
with that statement. Let’s start with angular
distance.
Let’s imagine a wall, exactly perpendicular
to your eye-of-sight, and at the exact centre.
For this example, we will ignore other variables
like curvature, refraction and such.
Given the distance between you and the wall,
with the wall’s width, we can calculate
this angular distance using Pythagoras.
So given the distance as adjacent leg, where
opposite leg is half the width, we can calculate
adjacent angle, which is half of angular distance.
So, if this wall was 1000 metre away, and
100 metre in width, our adjacent angle would
be around 2.86 in degree; and angular distance
would be 5.72 degree
Now, how wide does that wall needs to be,
if it was 10km away to have the same angular
distance. Well, it would be 1km in width.
Let’s look at it in reverse. A wall 10km
away with a width of 1km would look the same
size as a wall only 1 km away with a width
of 100 metre.
Call me stupid; but I don’t see how from
an angular distance we can figure out the
length. But that is just the beginning. We
globers say, it’s the refraction and earth’s
curvature that causes the sun appear larger
when near the horizon.
On a flat-earth model, for you to be able
to observe a larger sun, based on their assumption
on this paragraph must surely mean that sun
is closer to you at that point.
Again, on a flat-plane, if the sun is closer
to you when it is at horizon, then it means
the people between you and the sun must see
it much much larger; right?
It feels like for one section of the flyer,
you want to have the cake, and on another
section, you want to eat it. You can’t have
it both ways.
So what causes Crepuscular Sunrays? In gaming,
we call this God-Ray, which I think sounds
way much cooler.
Well simply put, gods ray happens when sunlight
passes through the air with bunch of stuff
in it.
The white light coming out of the sun is really
made of all the colours of rainbow, and what
makes them all different is really the wavelength.
The longest wavelengths we see look red to
us, where the shortest wavelengths appear
blue or violet.
When the light passes through our atmosphere,
thanks to the abundance of nitrogen and some
oxygen, short-wavelength light are scattered
more than others.
Much of the remaining wavelengths when mixed
together still appears nearly white, while
the blue and violet scatters and dominates
the sky. Some of the violet light is absorbed
by the upper atmosphere, and our eyes are
also less sensitive to violet than blue; thus
the sky appears blue.
But when the sun is near horizon: well, the
light has to travel through more air; so the
blue and violet are scattered even more, and
allowing the red and yellows to pass straight
through to our eyes without all the competition
from the blues.
This is the same reason closer to the horizon,
the sky fades to a lighter blue or white.
Now god’s ray happens when the sunlight
hits bigger particles, like dust and water
which bounces all the light’s colour pretty
much the same. Thus, most of the god’s ray
looks white.
When the god’s ray isn’t white: like during
sunset; well, it simply means the colour wasn’t
white to begin with.
Apart from the dust and water particles, we
also need something to block the sunlight;
without it, we wouldn’t be able to see the
paths of individual rays. Light would just
be bouncing off of everything equally.
Cloud just happens to be denser pockets of
water vapours and dust that are great at blocking
sun. But you can get trees and other structure
blocking the sun in a similar way.
But areas around cloud tends to have some
dust and water, and when sunlight manages
to break through the cloud; well, it would
hit a bunch of stuff to have it scattered.
Glorious God’s Ray.
If you manage to view it when the sun is at
the horizon: well, you will get to see god’s
ray that stretches all the way across the
sky. Like all god’s ray, they look like
they are being radiated from the sun; and
the rays going behind you, directly opposite
the sun is where they all seem to meet; as
if they are being radiated out from some invisible
sun.
The rays that are going behind you is called
Anti-Crepuscular rays.
So what is happening; well, as the sun is
so far away that when the light hits earth,
all the rays are virtually parallel. And thus,
the god’s rays are also virtually parallel.
Now I have talked about perspective in greater
length on one of my earlier flat-earth debunking
videos; sue me as I can’t remember which
one.
Long story short: if you look at a straight
train line, though the tracks are parallel,
they seem to get closer and closer at distance.
Imagine the god’s ray; parallel and behaving
the same way, and appearing to be radiating
from the sun.
And this is the same reason why Anti-Crepuscular
rays seems to be radiating from an invisible
spot opposite of the sun.
So, wait; if what I am saying is correct,
that would mean if we could see the god’s
ray from outside the earth’s atmosphere,
it would look parallel, right?
Exactly. This picture was taken by an astronaut
on the International Space Station provides
an unusual viewing perspective from above
of gods rays, and shows the true nature: they
really are parallel!
The photographer in me: oh yes, in case you
didn’t know… I used to be a photographer;
I even have a portfolio video in this channel.
So that me wants to shout out about polarizing
filter – but let’s not.
Well, that’s all for this video. Thank you
so much for watching. If you have enjoyed
this content: well, a like and a comment won’t
go amiss. If you would also subscribe for
future contents like this: it would definitely
help my small channel grow and would be thoroughly
appreciated.
Have a safe day; signing off.
