Praise for previous editions of Dinosaurs and the Expanding Earth
'something completely different ... an original work rather than a re-presentation of existing knowledge ... well presented.' GEOLOGY TODAY - Blackwell Science Ltd.
'Engineers (Hurrell) have shown that dinosaurs' bones could not have borne their weight ... much reduced surface gravity is essential for dinosaurs to have existed.' Professor S. Warren Carey, University of Tasmania.
'... written in a plain straightforward style and its target is a wide public not interested in specialist treatises. Its clear and lively descriptions lead the reader straight to the core of the arguments. ... could well be the topics of joint scientific collaboration between engineers and paleontologists.' ANNALS OF GEOPHYSICS
Stephen Hurrell has worked in different mechanical engineering design positions for various companies. It was his role as a mechanical design engineer at the UK’s Electricity Research Centre that first offered him his insight into how scale effects were pertinent to the biomechanical problems of the dinosaurs’ large size.
These thoughts about dinosaurs as engineering structures, and the problems of scale effects, fostered the development of the Reduced Gravity Earth theory and its implications for the Expanding Earth.

Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter embedded in the Milky Way. In a sense, it might have been dark matter that killed the dinosaurs.
Working through the background and consequences of this proposal, Randall shares with us the latest findings—established and speculative—regarding the nature and role of dark matter and the origin of the Universe, our galaxy, our Solar System, and life, along with the process by which scientists explore new concepts. In Dark Matter and the Dinosaurs, Randall tells a breathtaking story that weaves together the cosmos’ history and our own, illuminating the deep relationships that are critical to our world and the astonishing beauty inherent in the most familiar things.
