According to a 2008 paper in Applied Optics by David K. Lynch, the curvature of the earth becomes somewhat visible at an elevation of 35,000 feet (with a >60° field of view) and more easily visible at an elevation of 50,000 feet. So if you're on the right commercial flight, you might be able to see the curvature of the earth with your own two eyes.

In the event that you're not high enough, though, you can still experience the curvature of the earth another way. For example, if you were to fly all the way around the world, you'd find that it would be nighttime in part of the world and daytime in another part. In that way, the existence of time zones itself is proof that the Earth is round.

Taken another way, you wouldn't even need to travel through different time zones. Time zones are wide enough that you will see the sun rising and/or setting later in the western part of a time zone than in the eastern part. According to the Farmers' Almanac, the sun will rise and set roughly four minutes later for every 70 miles you drive from east to west.

If you wanted to combine this experiment with the previous one, you could note how much more of Earth you can see when you begin your ascent into the air than you can while you are sitting on the tarmac waiting to take off.

How come?@💕~𝑴𝒂𝒚𝒂~💕

With the flat earth the sun circulates over the earth

Which how times zones differ

6. Measure shadows across the country

Pick two locations that are some distance apart (at least a couple hundred miles from each other and on the same meridian). Grab two sticks or dowels (or other objects) of equal length, two tape measures, and a friend. Each of you will take one stick/dowel/object and one tape measure to your location, stick the object into the ground, and measure the shadow. (For accuracy, you should both take your measurements at the same time of day.)

On a flat Earth, the shadow that is cast by each would be of the same length. However, if you and your friend compare notes, you'll find that one shadow was longer than the other. That's because, due to the curvature of Earth, the sun will hit one part of Earth at one angle and another part of Earth at a different angle even at the same time of day.

This experiment has been around sin about 240 B.C., when Greek mathematician Eratosthenes compared the shadows cast in both Syene—now Aswan, Egypt—and Alexandria on the summer solstice. Eratosthenes had learned of a well in Syene where once a year on the summer solstice, the sun would illuminate the entire bottom of the well and tall buildings and other objects would not cast a shadow. However, he noticed that shadows were being cast on the summer solstice in Alexandria, so he measured the angle of the shadow and found it to be an angle of about 7.2°.

```HYMN TO "R"
Our Eratosthenes whose sticks measured the heavens,
Hallowed be thy name,
Thy circumference come,
Thy radius be done,
On Earth as it measures in the heavens,
Give us this day our daily shadows,
And forgive us for assuming the distance to the sun,
To give us the globe.
R-men```

what the-

Just ignore that

This was achieved by comparing the shadows of sticks in different locations. When the sun was directly overhead in one place, the stick there cast no shadow. At the same time in a city around 500 miles north, the stick there did cast a shadow.

If the Earth were flat then both sticks should show the same shadow (or lack of) because they would be positioned at the same angle towards the sun. The ancient Greeks found the shadows were different because the Earth was curved and so the sticks were at different angles. They then used the difference in these angles to calculate the circumference of the Earth. They managed to get it to within 10% of the true value – not bad for around 250 B.C.

Another piece of evidence for a globe is the difference between the night skies in the northern and southern hemispheres. The view is completely different because the Earth beneath you is pointing in a different direction. If the Earth were flat, the view should be the same. This can be made even easier by simply comparing when it is night and day in each country.

You can observe the planets as well. They all rotate, and watching over the course of a few days gives a clear picture they are spherical rather than flat. The chance that most of the planets are spherical but the Earth is flat seems very unlikely.

also

if earth is flat, are the other planets flat aswell?

anything to say to this? @PhumoZTYPE

On most fe models other planets are spheres. They think the world is flat since the world can sustain life, therefore it is unique. Therefore it somehow has special properties that make it flat

There’s no proof of planets being physical objects anyways for all we know they are just luminous objects in the sky

..

mars rover?

That’s nasa lying, we know they can’t be trusted

how do you know that then?

Like they lied about the moon landing

Why do you think they lied about moon landing

yeah why would they? what’s the point and where’s the evidence they did?

and don’t say fish eye lenses

Firstly how does a flag wave in space

Well it has no resistance aside from gravity, so it is allowed to flow freely

Another ‘giveaway’ that the landing was faked comes from the footage of the American flag that Neil Armstrong and Buzz Aldrin placed on the Moon. From photos and video, it appears to be flapping in the wind. But hold on a minute! There’s no air on the Moon so how can it flutter?!

The truth is that the flag isn’t flapping. If you look closely at the gif to the left, the flag is in the same position between two frames as the astronaut moves. There is a horizontal rod projecting from the post at the top of the pole to hold the flag unfurled. The flag was disturbed as it was planted into the ground and kept this bent shape because of the lack of strong gravity on the Moon.

In video footage of the flag being planted into the Moon’s surface, it also appears to wave back and forth. This is because when the astronauts were planting it, they rotated it back and forth to better dig into the lunar soil, which of course made the flag ripple as it swung like a pendulum- without a breeze. There’s a huge amount of footage of the flags stood on the Moon in exactly the same position.

;-;

And I think it’s foolish for them to say that the reason we cannot go to the moon anymore today is because they destroyed the technology and it’s a painful process to build it up again. We’re in 2019 and tech has definitely improved after 50 years

🤦🏼‍♀️

ok so

So did you look at nasa's yt channel recently

They are planning to

Go back to the

Moon

ye

And there’s an interview with Neil Armstrong and he is asked if he saw and stars and planets while in space and on the moon and he said he didn’t see any stars or planets , he just saw a deep black void and the earth but I watched another interview with Don Petit and he said he sees plenty of stars all the time in space. So who’s lying ?

@demonwarrior2266 yup

so u believe it was faked bc a story changed?

🤡

Well that could be explained. Neil lives in new york where there is a lot of light polution in the sky, so it is harder for him to see the stars and other things in the sky

He was in space

He said he didn’t see any stars and planets in space
