Here we go.

1. Watch a ship sail off to sea

Without being in the sky, it is impossible to see the curvature of the Earth. However, you can always see a demonstration of this if you visit a harbor or any place with a wide-open view of the water.

If you are able to watch a ship sail off to sea, watch its mast and flag as it fades off into the distance. You will notice that, in fact, it does not "fade off into the distance" at all; instead, you will see its mast and flag appear to slowly sink. The ship sailed beyond the point at which you would see it. Just to be sure, bring a pair of binoculars with you so that you can see even farther off into the distance.

It's as if you're watching it go over to the other side of a hill. This phenomenon can only be explained by a sphere-shaped planet.


2. Watch a lunar eclipse

Solar eclipses get all the attention, but if you are able to catch a glimpse of a lunar eclipse, you can see evidence that the Earth is, indeed, round. Here's how it works: Earth passes between the moon and sun, so that the sun projects Earth’s shadow onto the Moon in the night sky. You've probably seen a partial lunar eclipse without even noticing it; if the moon looks orange, that's a sign of a lunar eclipse. If you've ever seen a total lunar eclipse, you probably noticed that the shadow did not look like this.

A round shadow crossed over a round object. This does not sound like a thing that would happen if we were on a plane with all of the celestial bodies simply hovering overhead—or, perhaps more assinine, if the sun were orbiting Earth and not vice versa. The last total lunar eclipse took place on January 31, 2018, but it was not visible in most of the United States. Fear not, as you only have to wait a few months for one that will be visible in the Americas on July 27, 2018.


3. Climb a tree

Imagine a vast plane with but one tree smack in the middle. If the earth were flat, your vision would extend exactly as far while standing at the base of the tree as it would when at the top of the tree. However, the farther you climb, the farther your line of sight will extend to the horizon.

That's because parts of Earth that were concealed from view by its curvature are now revealed because your position has changed.

Back to the vast plane. The naked eye can see objects that are millions of miles away in space. Theoretically, with a clear line of sight on a clear night, one would also be able to see bright lights from far-away cities. That this is not possible is further evidence of a round, not flat, Earth.

@Madd_the_human

1. Perspective. Angular resolution. Optical slant.

2. Selenelion. You have no clue wtf is going on with the sun or moon.

Umm I do

Climb a tree?

We've climbed mountains.

Climb a tree? Thats the same as number 1

@🎃Oakheart🎃 he is saying you see more when you get higher

I have a A+ in astronomy

@🎃Oakheart🎃 he doesnt understand perspective

That's great

@Madd_the_human have you ever read the book kings dethroned?

No

Have you ever challenged what you were told?

By what means

Every means

Yes

Ok. Well i think you should read that book

Ships appearing to disappear in the horizon can be a result of A: Heat, B: General air quality and pollution, C: Fog or haze in the distance, D: Optical Illusions, ships can appear to float and sink, D: Much more.

Wouldn't the ship appear to sink if it was going into the horizon? Oh, but wait.

NASA says that we can't see the horizon, so how would that work?

Its how light works

Umm you can

Its not called angular resolution for no reason

How could a ship go far enough that we can see it sink, yet NASA says we can't see the horizon.

Ever been on a airplane and looked out the window

Incorrect.

You and see the curve of the earth

Warped glass, curved glass.

You dont see a curve regardless

He is lying

Have you tried my trick tho

What trick

The one I just said

Looking out a plane window?

Looking out a window isn't a trick.

😂

Are any of you guys going to the ice wall?
