Vacuum Diagrams is a 1997 book in the XeeLee Sequence by Stephen Baxter. More like linked short stories than a novel, this would be a great introduction to this universe. It's a well-respected series of books, and this particular one won the Philip K. Dick Award. I would enjoy this more, I know, if I had a clearer understanding of the science. But I don't, sadly, making some of it hard to picture in my mind. I enjoyed it anyway. Sometimes you just have to treat science beyond your understanding as magic and let your imagination do the best it can.
Some people don't care for science fiction because of the alien environment; but I find science fiction settings not really any more alien than an aboriginal village in Australia, or a community of tidal houseboats, or a light house, or the Arctic, or the ancient Middle East, or a tropical island un-touched by modern discovery, or any other environment foreign to my experience. The stories are human stories, dealing with human issues, and I wish people wouldn't judge before they make a fair trial of the genre. For some reason, people see a space ship on the cover and freak out. That said, this book wouldn't be a good one for someone new to the genre.
from the back of the book:
SF Site has a positive review. Ansible calls it a "fine, if uneven, collection" and says it "contains something to amaze everybody."
"And everywhere the Humans went, they found life..."
This dazzling future history, winner of the 2000 Philip K. DickAward, is the most ambitious and exciting since Asimov'sclassic Foundation saga. It tells the story of humankind -allthe way to the end of the universe itself.
Here, in luminous and vivid narratives spanning fivemillion years, are the first Poole wormholes spanning thesolar system, the conquest of Human planets by Squeem,GUTships that outrace light, the back-time invasion of theQax, the mystery and legacy of the Xeelee, and their artifactsas large as small galaxies; photino birds and Dark Matter;and the Ring, where Ghost, Human, and Xeelee contemplatethe awesome end of Time.
