Pardon my only basic understanding of physics. I'm not sure if the title is the correct question, but say I'm on a star many, many light years from earth. Can I theoretically see the freckles on my wife's face? It seems to me that light goes in all directions and the further it goes the less resolution there is so maybe I might be able to see one freckle but I wouldn't know that it is a freckle since I couldn't see anything else. How far off am I? Certainly the energy in the light diminishes, but if I had a supersensitive machine, is the data there? If the answer is yes, I could see them, is there any limit to the distance they could be seen even if there is a limit to the technology that I would need to actually see them? Thanks for your insight.
