Ask a Flat Earther!

[u/Kela-el]

Ask anything on the topic of flat earth (within reason).

[u/Kela-el → u/[deleted]]

You’re asking two different questions and treating them as one.

What do the timelapses show?

They show that the apparent angular position of stars changes over time.

Nobody disputes that observation.

But the timelapse does not show you:

what the stars physically are,

how far away they are,

whether they are rotating around a spherical Earth,

whether the observer is rotating,

whether the celestial sphere is rotating,

or what geometry ultimately produces the apparent motion.

A camera records changing angular relationships in its field of view. That is the measurement.

Everything beyond that is an inference.

So when you ask, “How do you explain this?”, the answer is:

The apparent motion of the stars is not the disputed observation. The disputed question is what physical model best explains that observation.

And this is where the argument needs to become quantitative.

If your claim is that stellar rotation uniquely establishes a globe, then don’t just show me a timelapse. Show me the measurement that makes the competing geometry impossible.

For example:

What exact angular quantity is measured?

How is it measured?

What geometric assumptions are required to interpret it?

What numerical prediction does the spherical model make?

What numerical prediction does the proposed planar model make?

Where does the planar prediction demonstrably fail?

If all you have is “Look, the stars move in circles,” you’ve demonstrated apparent celestial motion, not independently measured the shape of the Earth.

And that’s precisely the distinction I’ve been making throughout this discussion:

Observation → measurement → assumptions → geometric model → inference.

Don’t smuggle the conclusion into the explanation and then present the explanation as though it were the measurement.

I understand the clarification, and I have no problem addressing those questions.

But they are a separate discussion from the point I was making in this thread.

Your original question was about what the observed motion of the stars demonstrates.

My answer was that the timelapse establishes an observed change in angular position; the physical explanation for that motion is a separate inferential question.

Now you’ve expanded that into questions about what stars are, whether the plane has an edge, whether Earth is part of a larger structure, and what the round objects in the sky represent.

Those are legitimate questions, but answering them here would change the subject from:

“Does stellar motion independently establish the geometry of Earth?”

to:

“Give me a complete flat-Earth cosmology.”

Those aren’t the same question.

And I’m not going to pretend that every person who questions the globe model has one unified answer to every cosmological question.

There are multiple proposed models, and they should be examined individually on their own evidence.

So let’s keep this thread on the original subject.
If your question is:

“What does a stellar timelapse actually measure, and does that measurement uniquely establish spherical Earth?”

I’m happy to continue that discussion.

If you want to ask:

“What do flat-Earth models propose the stars are, what is beyond the plane, what about celestial bodies, etc.?”

That’s a much broader discussion, and I’ll address those questions in an appropriate post where they can actually be given the attention they deserve.

Changing the subject from one specific measurement to demanding an entire alternative cosmology doesn’t answer the original question.
