If there are aliens, what will they look like?

Perspective

the art of drawing solid objects on a two-dimensional surface so as to give the right impression of their height, width, depth, and position in relation to each other when viewed from a particular point.

Below is a photo of the Thorntonbank wind farm off the coast of Belgium.

Perspective viewing is a scale. It's obvious that as an object gets further away from you it's going to look smaller. We all know this from personal experience.

As wind turbines get farther away from you, one who believes in a flat earth model and uses the perspective argument would say the entire object would have to appear smaller and eventually could not be seen from a great distance.

They cannot account for the following picture. Only the bottoms of the wind turbines disappear from view. The tops of the blades are still plainly visible.

A wind turbine tower is about the same diameter as the thickness of the wind turbine blades.

If the earth and water were flat, and the blades are still visible, the tower should still be visible since they are the same size and physically attached to each other. Yet the towers are not visible. Yet you can watch the blades rotate below and above the horizon. Since flat earth believers say the water is flat, that vision should never, ever happen. The closer ones appear fully, and each one behind it is either dropping into the sea, or going beyond the horizon line. The further they get away, the farther below the horizon line they get. It has nothing to do with perspective, which is a scale. It's an observation that something has come up between the observer and the object. That something is the surface of the earth, be it a huge expanse of flat prairie or a large body of water, it's the surface of the earth, which is round, not flat. If it were flat, nothing would be blocking the view of the bottom of the object.

On a flat earth, you would be able to re-view them in a telescope. You can't, because they are below the horizon on a globe. It's just that simple.

...So answer me this this physics question; how can a vacuum system (space) exist next to a pressure system (atmosphere) without a barrier?

My understanding is...the majority of the mass of Earth's atmosphere is close to the Earth's surface...The higher above the surface the atmosphere becomes much less dense...at an altitude of say 100K the density of the atmosphere is so low it can be considered a vacuum...
Mass and density of the upper atmosphere eliminates the need of any type of so called "barrier"...

So it's not like the vacuum of space butts up against an atmosphere of 14.7 psi...
...even at the altitude of the ISS there is enough (density) atmosphere where it needs to be pushed back up on a regular basis...in a total vacuum this would not be necessary...

So your question does not apply to the Earth's atmosphere...there is no vacuum system directly next to a pressure system...
It's all about mass and density...basic physics...!

Ummm.. How about because of gravity. That is the attraction of air molecules to the mass of the earth. To say that a vacuum can't exist next to a pressure system is akin to saying gravity doesn't exist.

So answer me this: Why does barometric pressure fall as you go up in altitude? Why do they bother to pressurize airplanes?

This concept of gravity certainly is magic as it can determine the weight of objects and decide what can float (birds, butterflies) and what is held to the earth (oceans, people).
Bbbbbut 9.8 m/s^2. Sorry not buying it.
I'm not quite sure of the barometric pressure decreasing with increasing altitude in the flat earth domed system but I suspect it is simply density. Heavier air vs lighter air just like oil floats on water.

Great! So you should be able to repeat what you explained in an experiment here on earth.

How are you so sure there's a physical barrier? (go ahead, answer with a question about something else vs ever any answer that makes sense)

Easy if using the same radio waves as your cell phone. You know that fake thing like the internet that we use to communicate without wired connections. There is a time delay for the distance, but it's still bi-directional communication.

Not sure about the physical barrier but my faith (and logic) tells me there needs to be a barrier separating something like air/space, even in the globe earth concept. Actually there is a video of a good size rocket that is sent up (by private individuals) with a camera and the video shows the rocket hitting something, stopping and then falling back to earth.

Radio waves traveling 170+millions miles and pinpointing a small object on a planet that is also "rotating" and "revolving" around the sun? Yeah, sure. Takes too much faith to believe in that.

Beam me up Scotty!

What?...LMAO...no need for any "experiment"...it can simply be observed...what would be the purpose of duplicating something on a small scale when it can be observed in full scale in real time...anytime ?

I can explain it to you but I can't understand it for you...!

birds and butterflies don't float.

Good point.
