No, it's not possible to take a 3D surface and to transpose it onto a 2D plane without any distortion.
This is true. There are some projections that show area more accurately, or shape of landmasses, etc.
For example:
Many map projections do one thing well at the cost of sacrificing others. For example, the popular Mercator projection (which you'll see in many US schools and textbooks) is well suited for marine navigation but is exceptionally distorted the closer you get to the poles.
I kinda like how the Kavrayskiy VII projection looks. It appears to preserve both the area and the shape fairly well.
this kind of projection is my favourite, it just looks like a map that belongs on a wall
Which makes perfect sense for its use case - navigating from Belgium, Portugal and Spain to Africa, India and Central and South America.
You can easily do it without distortion. The issue is continuity. You'd have to make cuts and effectively unwraped the globe like you would a 3D sphere. Some countries might literally be cut in half, but it would at least be accurate
There will still be distortion, just less. The more cuts, the less distortion. But you can't make an unwrapped sphere lay perfectly flat.
Erm, yes you can, just run it through the infinite-cuts device!
Or without chopping it up in an odd way rather than a rectangle.
My fucking..
