You are confused, alan. The TS & CS are two completely different coordinate frames and don't depend on each other in the least. You don't need to merge them, you don't need 60nm/°, and neither one of them are "conceptual spheres (wtf is that?)". They stand alone as separate & independent coordinate frames — TS for lat/long on Earth, CS for the position of stars. I can see how someone who didn't specialize in math could be confused by the coordinate transformations. In order to relate lat/long to ra/dec, the angles between the axes of the frames are needed, so that might look like "merging" to you, but the TS & CS do not depend on each other. They stand alone and independent as two different, well defined on their own with no dependency on the other, coordinate frames. They can be related to each other, just as any coordinate system can be mapped into another. And you say "fictitious positions of stars"??? wtf is that horseshit? There's nothing fictitious about stellar positions. We have the precision of bright stars down to microarcseconds and the rest to sub-milliarcsecond which includes aberration, parallax, and proper motion. ➡️The "fictitious observer" is your red herring. ➡️CS & TS are independent of one another. ➡️A coordinate transformation is required to relate positions in one frame to the other.

A bit of flat earth history for you. About 3 or 4 years ago, the original @100KryptoKeyz hosted Flat Earth Fridays had a space that went for over 24hrs. The topic: how can southern flights work on a flat earth. No viable solution was found after a full day of discussion.
Because either your payed or stupid to constantly keep saying the same thing when there's more examples for the flat earth maps working better for flight routes. I already know how those debates go. Why waste the 100th hour on it.. And no it's admission of defeat where you have to cope about "give me a map" when I'm showing a leveled camera showing no horizon recession. Yet you keep on about the whataboutism of a map haha

Have you watched Alan / Piezo / Toby’s presentation yet? You’d have to consider that a blow. The material demolishes FE and shows the only viable solution is a globe

We had Piezo in Globe Realities space a couple of days ago. He acknowledged it had taken him almost 9 years to realise he was wrong

More incontrovertible proof of heliocentrism. Only by living in a fairytale non‐reality, can one believe Earth is flat/motionless.

flat earthers think this is painted on the inside of a giant salad bowl. The salad bowl keeps all the air in (no leaking at the edges where it rests on the ice wall) and is spinning at 3,250mph. What silliness... cc: @ThatGuyM77 @ken_caudle @DrMikeHeffron @joekhanveyFE

varies linearly with distance from the pole, but is independent of longitude. Now ask yourself, what geometric object has this property. I'll give you a hint:

. Balls forming Gas in Space
Supernova remnant Cassiopeia A between 2022 and 2025. JWST NIRCam In this black-and-white JWST NIRCam F444W sequence, the remnant’s expanding clouds come alive: the upper-right shell pushes outward while knots stream across the lower left, and the fastest-changing patches glow as light echoes—the original explosion’s light still scattering through the surrounding dust. It’s not just expansion. New bright material appears near the center and along the upper-left rim even as other material streams toward the lower right, as if the remnant is still lighting up fresh structures in real time.

. Gas forming Balls in Space
🌌 The Orion Nebula (M42) This is a nearby stellar "nursery," visible to the naked eye near Orion’s Belt. The light from hot, young stars illuminates the surrounding gas and dust, revealing regions of active star formation. It spans about 40 light-years and lies approximately 1,500 light-years away. It is located in the same spiral arm of the Galaxy as the Sun. Within it, one can find the Trapezium cluster, protoplanetary disks, and jets of matter emanating from young stars. 🔭

The First Family Portrait of Earth and the Moon On September 18, 1977 — just 13 days after launch — Voyager 1 looked back and captured something no one had ever seen before: Earth and the Moon together in a single frame. From 11.66 million kilometers (7.25 million miles) away, two slender crescents hung in the blackness — our home and its companion, shown for the first time as complete worlds in the same view. Eastern Asia, the western Pacific, and a slice of the Arctic were visible on Earth. At the moment the picture was taken, the spacecraft was positioned almost directly above Mount Everest, on the night side of the planet. The Moon was artificially brightened by a factor of three so it wouldn’t be lost next to the much brighter Earth. The final color image was assembled from three separate exposures taken through different filters. It was the first time humanity saw itself and its Moon this way — a quiet, distant glance homeward long before Voyager 1 would later capture the famous Pale Blue Dot from the edge of the solar system.

These four points prove we live on a globe: • Easter Island (Chile) — near Hanga Roa ≈ 27.11° S, 109.43° W • Northern Cape, South Africa (Kalahari / near Reivilo) ≈ 27.51° S, 24.10° E • Greenland ice cap ≈ 72.64° N, 41.92° W • Western New Guinea (Indonesian Papua) planned ≈ 2.11° S, 137.39° E installed marker ≈ 2.35° S, 138.00° E

... They prove a globe because everyone of the four points is the same distance from every other point. They sit at the corners of a regular tetrahedron: a pyramid made of four identical equilateral triangles. A flat surface can hold only three points that are equally far apart (an equilateral triangle) . A sphere can hold four. These four points fit on Earth’s surface. So the surface cannot be a flat plane. It must curve like a ball. Earth is a sphere.
