Often in such collections, you might find authors who are experimental in their writing. They could be relatively new voices in science fiction or established ones with a penchant for the extreme. However, without actually looking at the book, it's hard to name specific authors. But some might be those who like to explore very different concepts like the nature of consciousness in a technological age or the far - flung reaches of space exploration in a more radical way than traditional science fiction.
Well, it probably has a great collection of extreme and mind - bending ideas. Since it's an extreme science fiction book, it might contain stories with unique settings, like distant and strange planets, or future societies with very different values and structures compared to our own. Also, the book may have stories that really push the boundaries of what we consider possible in science and technology.
I'm not exactly sure which specific authors are in it, but it's likely to include well - known science fiction authors. Maybe some like Isaac Asimov could be in there. His works are often full of interesting scientific concepts.
Well, it could have stories centered around the discovery of new forms of energy that completely change the way the universe is perceived. For example, a story where a scientist discovers an energy source that can open portals to other dimensions. In this book, there might also be stories of artificial intelligence that gains true sentience and then has to deal with the moral and ethical implications of its existence.
Well, it might be special for its comprehensive collection. It probably showcases both classic and contemporary science fiction pieces. This gives readers a chance to explore the evolution of the genre. For example, it may have stories that were revolutionary in their time and still hold significance today, as well as new and emerging voices in the world of science fiction.
Since I don't know the exact contents of the 'Mammoth Book of Apocalyptic Science Fiction', I can only guess. Some contemporary authors who are known for their apocalyptic stories could be in there. For instance, Margaret Atwood with her 'Oryx and Crake' series which presents a post - apocalyptic world. There might also be lesser - known but talented authors whose works have been selected for this anthology, and they could bring fresh perspectives on the apocalyptic science fiction genre.
