First off, those animated photos are, of course, not how it is in real life. They're just a visual representation. Water seeks it's "level" because there's a force acting upon it. Gravity (yes grabbity reeeeeeeee). The vector of that force points to the centre of mass of the earth. Water's "level" will be perpendicular to that vector (in short distances where curvature doesn't matter). Enough of those "perpendiculars" will result in a curvature. Enough curvature will result in a globe, with "curved" oceans

Without any external force acting upon water, it will turn into a sort of round shape. This is due to the fact that water has "H-bridges" (idk what the proper name is in English)

you are talking about hydrogen bonds and surface tension. and if you place a drop of water onto a hydrophilic surface it will spread out...in the ultimate limit to a flat surface

bodies of water are flat. many long distance laser tests confirm this.

What persuades you to look towards flat earth?

I was sleeping

@ReddySetGo what do you mean? it's probably the most important truth you can uncover

because of the implications

especially if you are atheist......like I was

@Flat Earth PhD That's literally not true. Where did you hear that water was flat lmao

Water takes the shape of its container.

so if i filled a ball with water

and then took the water out

id have a hydrosphere?

nice

The reflection on a plane vs curve pic is a bit misleading.

technically we shouldn't even see a spot should we? shouldn't a reflection be on the other side of the "hump"?

Lol exactly

Morning doc!
Not according to my 3D sphere there. If the sun is visible, there's a reflection.

That's a parallel light used, too.

ah ok. I'm still scratching my head over this one. not intuitive I guess.

need to find my bowling ball and light it up

seems the reflection would be on the other side but need to test

assuming the sun were far far away

haha, well, you might need something bigger. The above test was in the right direction, but the problem is the camera is *behind* the curve instead of on top. At any point on a globe, you are technically at the top of the curve looking "down."

The camera position in the original pic would technically be "off-planet".

I hate it when my camera goes off-planet. always when I don't want it to 😩

lol!

Murphy's law I guess

what a rascal that camera is

If your camera can go off-planet, it will

I still want a solid explination as for why the night sky changes as you move up and down in lattidue on earth
