Fermi's Question

Rate this book
It has been 15 years since the events of Einstein’s Bridge . George and Alice Griffin and Roger Coulton have established the Iris Foundation, a powerful island-isolated research organization tasked with exploiting the technologies learned from the Makers, re-learning Maker techniques for creating wormholes, reestablishing contact with the Makers, and protecting Earth from Hive invasions. Sparked by a new idea from Roger, Iris researchers finally master wormhole technology and use accelerated wormholes to create Fermi Station in the Oort Cloud. Contact is established with the Makers and the Centaurs, a justice-seeking robotic civilization in our galaxy. The triple alliance mounts a three-pronged attack on the Hive world, destroying the Hive and one of its colonies. A second Hive colony cannot be located and could pose a future problem. Iris launches an armada of accelerated wormholes to probe nearby star systems and establishes a colonization base on Orca, an Earth-like moon of Bowhead, a giant planet in the Tau Ceti system. Mankind has reached the stars.

A wonderful example of my favorite genre: hard science fiction

A welcome and fitting sequel to the author’s Einstein’s Bridge, with both high adventure and a deep but accessible tutorial on high-energy physics, cosmology, and general relativity. Kudos!.

Fantastic second book in this series, and a fascinating section at the end of the book, explaining much of the science used in the story. If you're a scifi fan with science leanings, you really don't want to miss this book. The material at the end of the book is worth reading all by itself. It's rare that an author takes the time to explain the science used in the story, and in this case, it enriches the story by leaps and bounds to have those explanations, as well as providing hours of entertainment just chasing down references to said matter. Great stuff here folks. Highly recommended.

Fantastico! Letto in pochi giorni nella versione Kindle in inglese.
Forse un po’ troppo ottimistico ma, ripeto, bello e avvincente.
