For me it’s definitely a book that often doesn’t get much love: Spin by Robert Charles Wilson. I read that book like ten times by now in both English and my mother tongue. Such a defining book for me since I first read it in my youth and it gave me a lot of food for thought regarding what it means to live a meaningful life. It is not really hardcore sci-fi after all but more a kind of coming-of-age novel that happens to take place in a sci-fi setting.

Is it just burned from regular shells or is the white stuff the remnant of phosphorus ammunitions?

Wtf haha, where does this come from? Googling only spits out variations of this meme and even the oldest ones already looked fried.
