それで、私の本が行われる可能性のある場所を思い付くのを手伝ってもらえますか？宇宙のライフサイクルの終わり近くで行われるSFの本が欲しいです。その時までに人間がどのような種類の構造物を建設できたのか、大きな船の構造を持つだけでなく、場所をより面白くするにはどうすればよいですか。
So could you help me come up with places my book could take place in? I want a sci-fi book that takes place near the end of the universe's life cycle, when all stars have died and only black holes remain. What type of structures could humans have built by that time, how could I make the locations more interesting instead of just having big ship structures.
