subtend

I think your use of ‘problem’ subtends a subtle bias.

This implies that N pixels will subtend less than N times the angle one pixel subtends.

At 1400 ly that would subtend a distance of 13 AU, so you wouldn't be able to find Earth-like planets.

Find the moon's distance by parallax, then the radius follows from the angle it subtends.

Almost no matter how zoomed in we are or are not, the energy bolts will subtend roughly the same amount of our eyes.

The fact that one pixel subtends a particular visual angle does not imply that N pixels subtend N times that angle.

On a flat screen, this is normal and expected, because a pixel further from the eye will subtend less angle than a pixel closer to the eye.

The regimented gender-divided situation the US seems to subtend is utterly alien to me and seems to be far more awkward than you realize.

Yes, otherwise even a laser beam that diverges slightly from being perfectly collimated would subtend a fraction of the night sky and thus contain a large number of galaxies.

Specifically, the "px" specifier now is a scaled length unit, and corresponds to whatever length subtends the same arc in a user's field-of-view as would a single pixel on a typical desktop display at about two feet away.

An optimal display would be curved so that each pixel subtends a roughly equal visual angle, and it's only the fact that most displays subtend a relatively small visual angle that allows us to approximate this with flat displays.
