When I scroll out, I would expect to reach a point close to Earth or our solar system, but somehow, I look at a sphere from the outside.

- elliotto 2y agoA fun fact I learned while visiting the Globe Museum in Vienna, is that they used to make globes in pairs; one would be a globe of the Earth, and the other would be a Celestial Globe which is a projection of the sky onto a sphere. What you're seeing is a celestial globe https://en.wikipedia.org/wiki/Celestial_globe https://en.wikipedia.org/wiki/Celestial_globe
- bscphil 2y agoIt's just a projection, you're looking at the sphere of the sky as seen from a (stabilized) Earth position. When you zoom out, you increase your field of view beyond that of the human eye to encompass the whole sphere. Because there's no way to compress a sphere into a plane, you have to choose a projection; this is a common projection (stereographic) which lets you zoom out as far as 180 degrees, by presenting the field of view as if it were the surface of a sphere as seen from an infinite distance.
