This sort of question is usually at the beginning of a headache. I leave the astrophysicists and philosophers to answer these oddities and paradoxes. I set myself a solvable question.
Does the snow that falls past my window in very cold Berlin, over time obscure all lines of sight? Sampling at 10 frames a minute over 20 minutes, I am unhappy to report, it has not yet achieved this perfect whiteout. My field of cold white stars is still incomplete. I hope more snow will fall.
