Mammoth Books presents Anomalies [EPUB ebook] 

Craftsman and amateur astronomer Geoffrey Carlisle from Ely discovers that the moon is fractionally ahead of its usual elliptical orbit. He becomes instantaneously well-known for his unique observation. Using Carlisle’s findings, astronomy experts discover that each star circling the moon has been slightly warped. Yet after some time, as Professor Wright from Cambridge University had predicted, the warped stars return to their rightful places, suggesting that the world is an information-ordered one, like an analogue program acting out. What then, are the actual repercussions of a computational error in reality?
