If there are aliens, what will they look like?

A flat earther dies and goes to heaven. At the gates of heaven, St. Peter says to him, "Before you enter the gates of heaven, you may ask God one question." The flat earther asks, "God, is the earth flat?" God responds, "The earth is 100% a globe." The flat earther exclaims, "Holy crap! This conspiracy runs deeper than I thought!"

No offense but since you believe that you possess knowledge that the majority of actually educated people don't...I must say...!
Just an observation...You obviously suffer from some form of delirium...you keep referring to yourself as an engineer...LMAO...degrees from the likes of Mad Magazine etc...don't count...based on your comments you obviously live at a very low level of awareness and are oblivious to your own gullibility...

You went down the path of uncivility very quickly. Do you feel like your faith is being attacked?
Yes, got my BSME in 1989 from the University of Texas at Arlington. The Steel Construction Manual is a good reference for designing structures as the data is tried and tested.

I stated "no offense"...just making an observation...
I have a copy of the steel manual (which needs updating on a regular basis because of technology and other factors effecting steel properties)...it was a reference book not a textbook in the classes I took becoming a CE...
But that brings up a point...( unrelated example) your comments remind me of all the Internet jokers that swear up and down they have college degrees but don't know the difference between their, they're, there...etc...
There is no way anyone can get through a 4 year degree program without being able to accept certain knowledge based on theoretical physics etc...

I heard that the COVID pandemic really took it's toll on the actual number of those that think the Earth is flat...it seems that the 6' distancing rule pushed a lot of members over the edge...!!

A bit off subject, but thought I would put in my 2cents worth. I know three individuals who told me they have an engineering degree. With my background (BS in Biology and Chemistry) I could tell, from later conversations that they were lying. Two of them have passed; neither had anything near an engineering degree (from their obits).

I suppose, since an engineering degree indicates both intellect and a lot of hard work, they thought it would impress others...but they didn't know that at various times, I had worked for, with and was legal counsel to engineers all of my career.

From the article linked above:

"People who believe that Earth is flat aren't coming to that conclusion from the same types of observations. Instead, they believe that we are being misled and lied to, that scientists want you to believe that Earth is round, despite its flatness.

So the question isn't "Why do people believe in a flat Earth?" but rather "Why do people believe in a conspiracy?" And the answer is the same reason it always is: a lack of trust.

Many people don’t trust the society around them, most notably the representatives of that society. That trust often falls even further when it comes to elite representatives of that society, which include government officials, members of academia and scientists. By claiming that Earth is flat, people are really expressing a deep distrust of scientists and science itself."

Eratosthenes started the big lie of Earth's round shape 200 years before Christ, if you believe that he wasn't fake news too. Our government doesn't deny his existence and goes so far as to acknowledge his followers as patriots, but who believes a bunch of liars? btw, Apologies that I believe I owe income tax and pay it every year.

Trade, no, not easy. The accelerometer works properly on all axes so that it clearly only responds to acceleration. No matter what orientation you pick the axis normal to gravity responds the same way, reading 9.8 m/sec^2 while stationary. You did not read or understand what I wrote, or do not understand how these devices work, and must not have ever seriously used one, or what I am saying would be clear to you. Bulletproof.

We had a fairly civil debate but it is time for me to bow out. No one is going to change their mind. Thanks, although we disagree, the debate is more challenging than I thought.

Do these devices NOT sense earths motion around the sun? or the motion of our spiral galaxy? or the motion of our expanding universe?

Pathetic devices if made so crudely.

They do not sense it. An accelerometer only respond to acceleration, not constant velocity. The earth revolving around the sun is not changing velocity. To be clear, any orbit by nature has an angular acceleration, but the angular domain is not the domain of an accelerometer, it is the domain of a gyro.

Any orbit is an angular acceleration. Double speak is not a solution.

How can one visualize the difference between "angular acceleration and gravitational acceleration? Recall those "artists conceptions" of torroidal space stations rotating slowly to produce the feel of gravity? Not any easy concept to hide.

The calibration of 9.8 m/sec ^2 accounts for the centripetal, and "is corrected for the straight line momentum ".

And what do these devices produce as output when thown upwards to the sky by a nine year old? Only to fall back again and bounce as a rubber ball down the sidewalk? Ignoring the the pull of the moon and stars?

There are more and more engineers waking up to the truth so don't know why you can't believe it.
There's physics and there is theoretical physics.
So answer me this this physics question; how can a vacuum system (space) exist next to a pressure system (atmosphere) without a barrier?

Well my brother, a retired aircraft mechanic, believes that planes have software that automatically compensate for the "curve" of the earth so that pilots don't have to constantly dip the plane to follow the curve. When I asked him if he's seen this software he shrugged his shoulders. I also ask him if a pilot puts the plane in manual mode and flies the plane himself why the pilot doesn't have to constant dip the plane to follow the "curve". No answer.
Don Petit, astro-not, said that they would go to the moon in a nano second but lost the technology and it would be painful to build it back.
Even though NAZA is supposedly sending rovers to Mars and has this magical ability to control these rovers from 172 million miles away.

There is absolutely no proof for this statement. With all the relative motion going on in the globe earth universe (sun, moon, earth, planets, solar system) there would be no way to figure out what's moving and how fast.

Unless aliens know how to warp space/time - it's likely our visitors will be some form of robotic probe. Same applies to us. There is currently no know way for humans to survive the time needed to reach even the closest star systems. Much less simply surviving in space.

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 cel 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.
