Any photo we are to take today is limited in clarity by the pixel count of that photo.
That is to say, a very far object might only appear as one pixel on the picture, rendering it unable to be identified.
But, if we were to take that same photo from the same location but with a strong enough telescope, then the object would be covered by more pixels, increasing its resolution and allowing us to identify what it is.
Then, assuming that there are no obstacles obstructing light, if we had a sufficiently strong telescope, we could clearly resolve an object of any distance when observing from a stationary reference point.
Yet, the distance between the object and our stationary point of observation grows exponentially in while our eye at the telescope remains a fixed cross-sectional area, resulting in a more "pixel dense" image as we increase the strength of our telescope.
This gives rise to the question: Is it possible to resolve an object infinitely far while keeping a set cross sectionary area and stationary point of observation?
In other words, how "pixel dense" is light? How much information could light carry?
