Book: The Disappearance of the Universe
Usually abbreviated as “DU”
This unremarkable guy Gary, opens his eyes one day after a meditation session to see two people sitting on his sofa, apparently having materialised out of thin air. Despite the strangeness he finds himself engaged in a conversation with them. And it is a fascinating conversation - the most interesting conversation I’ve ever read. At the end of the conversation they say they’ll be back, and then they disappear before his eyes. They visit him a total of 17 times and discuss many things and answer all his foolish questions. The book is mostly just a transcript of those conversations.
The first chapter can be read for free here.
