Also this view might include red dwarfs which make up like 75% of all stars and are not visible to the naked eye at night (and wouldn't be even if you were in space on the dark side of the moon. they're too dim compared to the sun). When you add them in galaxies are much more dense with stars.

It's definitely either an ostrich or giraffe, one of those long neck fuckers

Well shadows are the absence of light, so defining them is a little weird, but they exist the entire distance from where the light source is interrupted to where they are projected on, same with projections, it's not just what's on the screen, but the light the whole way to the screen.

Even ignoring that, the surface that a projection lands on has texture and depth.

Are jandals sandals that are made out of jeans?

We've never seen anything 2 dimensional. Everything we can see has some form of all 3 dimensions in it. Even shadows are 3 dimensional. We conceptualize them as 2 dimensional on a wall, but they have depth. (Think of how when you see a line it's actually 2 dimensional due to the width of the line, then apply that concept to depth as well)
