We can. But then we have to agree not to post Flat or Sphere Earth stuff here?
@MR VLAK Nope, just that you and me will not ever come to a conclusion on the matter. All avenues have been exhausted here and from here it's just a waste of everyone's time. Go do some actual research, and come back when you actually have some proof of your own you can back up with more than just your mouth.
Fine we carry on then. Genesis 1:2 And the earth was without form. Yet you claim it flat because a sphere doesn't have a face
Rather selective in your interpretations...<:Hmm2:469473861654806531>
do you believe that Horus & Jesus share the same story?
just by the way read what Satanists have to say about FE's http://www.satanicsf.com/flat-earthers-satan-conspiracy/

Checking out some spots at the Vaal Dam to go and repeat the Bedford Level experiment.
Elvis is alive
Will be doing day and night tests. Got houses at both ends which will make it much easier to spot targets at night across the water.

Thanks I cannot wait to see refraction of light proven
Please take air temperature measurements so we can calculate the amount of refraction
Errrrrr
Why not tip the line more backward, it will be even longer
The code is fucked, despite this. It can't even calculate my input.
See what happens if I mount my camera 100mm above the ground. Oops
This app calculates how much a distant object is obscured by the earth's curvature, and makes the following assumptions:
light travels in straight lines
You can see 1.1 km far, and the curve change to 3 m drop over the 7km, hu, uh? Hi Pythagoras.

Should you not be accounting for refraction when calculating the hidden height? This is explained by Andrew Young here:

If you aren't going to include this in the calculation then you at least need to state so clearly on the calculator page.

Please, could you explain how did you get h1 calculation from the second line?
Where is gone the 2Rh1 from squaring the left side of equation?
Thanks!

The formula laid out doesn't caluclate distance well, as line of sight is not the measure of distance across a globe. instead I would make the assumption that the distance is an arc segment. This has the added benefit that when d_surface_0 < d_surface_1, the heigh for an obscuring object is calculated.
Example python code
from math import pi,inf,acos,cos
R=6371*1000
h_1 = 2
d_surf_0 = R*pi
theta_1 = acos(R/(h_1+R))
d_surf_1 = R*theta_1
print("horizon: %.02f" % d_surf_1)
d_surf_2 = d_surf_0 - d_surf_1
theta_2 = d_surf_2/R
if theta_2 > pi/2:
h_2 = inf
else:
h_2 = R/cos(theta_2)-R
print("height: %.02f" % h_2)

__Experiment 1: Watch a lunar eclipse__
Things you’ll need: functioning eyes, the moon, and a telescope (optional).
Every now and again, the Earth passes between the moon and the sun, completely blocking its light and casting a shadow across the moon called a lunar eclipse. If you look closely while this happens, you would notice that the Earth’s shadow forms an arc as it creeps across our view of the moon.
You might respond, “You’ve shown the Earth is round, but couldn’t it be round, but still flat — a flat disc?” Well, your eyes and telescope would also spot the 3D spherical nature of the moon. The Flat Earth Society does admit that the moon, the sun and other planets are indeed spherical, but claim that the “Earth is not a planet,” and unlike other celestial bodies, is flat.
So let’s ignore the moon for now and examine the other member of the eclipse trifecta: the sun.

__Experiment 2:__
The horizon is one of the easiest ways to validate the Earth’s curvature. As the sun dips behind the horizon, it slips from your view in a bottom-up direction. If you watch the sunset while lying on your back, and then hop up as the last rays disappear, then you should be able to see the sunset again.
Flat Earther concepts don’t stack up, especially when placed against modern technology like global air travel…or telescopes.
Instead, their ideas require leaps of faith that far outpace a 5’0 teenager stretching his fingers toward a rim.
Fake science
But when science experiments are performed incorrectly they can appear to give the opposite result. If they are shared through social media, these false ideas can be spread quickly with no one to point out their flaws. One common example is the Bedford Level experiment, a form of which was first carried out in 1838 and used to "prove" the Earth was flat for over 30 years before an explanation was found.
.
This experiment involved placing a marker at a set height at either end of a canal about six miles long. If the Earth is round, then one marker should appear lower than the other when viewed at the same time through a telescope because the furthest marker would have fallen away with the curvature of the Earth. But it was reported that the markers are the same height, suggesting the Earth is actually flat. Modern day Flat Earth theorists still quote this experiment.
.
The problem is this doesn't take into account the optical effect of the air over the intervening water, which bends or "refracts" the light as it travels from the marker to the telescope and makes it look like they are the same height. The solution is to use multiple markers along the length of the canal which, when observed, all appear to be at different heights.
Perhaps the most impressive experiment that even schools can do today is to send a camera up in a high-altitude balloon. The footage will show that from a high-enough vantage point you can see the curvature of the Earth. This is what Mike Hughes will find if he ever makes his rocket work.
Ultimately, arguing on the internet is not the best way forward for any scientific endeavour. We need to provide the means for people to test these theories themselves and to understand the results they get.
50) If the Earth were truly a globe, the Arctic and Antarctic polar regions and areas of comparable latitude North and South of the equator should share similar conditions and characteristics such as comparable temperatures, seasonal changes, length of daylight, plant and animal life. In reality, however, the Arctic/Antarctic regions and areas of comparable latitude North/South of the equator differ greatly in many ways entirely inconsistent with the ball model and entirely consistent with the flat model.
50) obliquity
Earth has seasons because our planet’s axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane – the plane of Earth’s orbit around the sun.
Over the course of a year, the angle of tilt does not vary. In other words, Earth’s northern axis is always pointing the same direction in space. At this time, that direction is more or less toward the star we call Polaris, the North Star. But the orientation of Earth’s tilt with respect to the sun – our source of light and warmth – does change as we orbit the sun. In other words, the Northern Hemisphere is oriented toward the sun for half of the year and away from the sun for the other half. The same is true of the Southern Hemisphere.
When the Northern Hemisphere is oriented toward the sun, that region of Earth warms because of the corresponding increase in solar radiation. The sun’s rays are striking that part of Earth at a more direct angle. It’s summer.
When the Northern Hemisphere is oriented away from the sun, the sun’s rays are less direct, and that part of Earth cools. It’s winter.
Seasons in the southern hemisphere occur at opposite times of the year from those in the northern hemisphere. Northern summer = southern winter.
The tilt in Earth’s axis is strongly influenced by the way mass is distributed over the planet. Large amounts of land mass and ice sheets in the northern hemisphere make Earth top-heavy. An analogy for obliquity is imagining what would happen if you were to spin a ball with a piece of bubble gum stuck near the top. The extra weight would cause the ball to tilt when spun.
51) Antarctica is by far the coldest place on Earth with an average annual temperature of approximately -57 degrees Fahrenheit, and a record low of -135.8! The average annual temperature at the North Pole, however, is a comparatively warm 4 degrees. Throughout the year, temperatures in the Antarctic vary less than half the amount at comparable Arctic latitudes. The Northern Arctic region enjoys moderately warm summers and manageable winters, whereas the Southern Antarctic region never even warms enough to melt the perpetual snow and ice. On a tilting, wobbling, ball-Earth spinning uniformly around the Sun, Arctic and Antarctic temperatures and seasons should not vary so greatly.
Same as #50
52) Iceland at 65 degrees North latitude is home to 870 species of native plants and abundant various animal life. Compare this with the Isle of Georgia at just 54 degrees South latitude where there are only 18 species of native plants and animal life is almost non-existent. The same latitude as Canada or England in the North where dense forests of various tall trees abound, the infamous Captain Cook wrote of Georgia that he was unable to find a single shrub large enough to make a toothpick! Cook wrote, “Not a tree was to be seen. The lands which lie to the south are doomed by nature to perpetual frigidness - never to feel the warmth of the sun’s rays; whose horrible and savage aspect I have not words to describe. Even marine life is sparse in certain tracts of vast extent, and the sea-bird is seldom observed flying over such lonely wastes. The contrasts between the limits of organic life in Arctic and Antarctic zones is very remarkable and significant.”
I wonder what effect ocean currents have on a continent? mmm.. 🤔
“Why is the North Pole warmer than the South Pole? I changed it each year, to confuse students who looked at last year’s exam; “Why is the South Pole colder than the North Pole?” Most people have no idea about the geography of the Poles and assume they are climatically the same. They are literally polar opposites and that is important in understanding the significance for global climate.
The major driving force for atmospheric circulation is the temperature difference between the Poles and the Equator – the gradient. Theoretically, maximum heating at the Equator and minimum at the Poles creates a single cell circulation system (Figure 1).
Figure 1
Rotation is the major perturbation to this theoretical base, followed by surface differences, particularly land/water ratios.
Earth’s elliptical orbit round the Sun is a small factor in determining the temperature difference. Two important points are perihelion, when the earth is closest, and aphelion when it is furthest away. (Figure 2)
Figure 2
The current situation is as follows.
The Earth is closest to the Sun or at its Perihelion two weeks after the December solstice and farthest from the Sun or Aphelion, two weeks after the June Solstice. In 2015, the Earth will reach its Aphelion at 19:41 (7:41 pm) UTC on July 6, 2015.
All this changes as part of the larger Milankovitch Effect, but it means that at present the Earth is closer during the Northern Hemisphere winter and further away during the Southern Hemisphere Winter.
At the risk of stirring up solar specialists, here is one estimate of the insolation difference.
Aphelion Insolation = [(149,597,870.7 km) / (152,098,232 km)] = 0.9674
Perihelion Insolation = [(149,597,870.7 km) / (147,098,290 km)] = 1.0343
It’s approximately a 6.5 percent variance, which is a minor difference but one amplified by other factors.
