Very good comparison. Wish I had thought of it.
Although for a better comparison(now that you've got me thinking about it) about a milliliter of air put into a ten million liter box would provide about as much distortion and light filtering as what actually happens. Space tends to be very empty.
As for Anromeda, we've got some pretty good pictures of it, most of them use different elecromagnetic wavelengths than what the human eye can see, which means that many of them can pass through objects with very little distortion instead of being absorbed as light would so the wavelengths have to be converted using computers to allow us to see them, when this happens they also filter out static, and various other distortions are corrected using massively complex physics programs. NASA and other organizations do not spend billions of dollars every year to take pictures and then not make sure that they are as clear and accurate as possible. Why do you think they spent so much money fixing Hubble instead of just using fuzzy photos?
