Review ''Only Lisa Randall can take us on such a thrilling scientific journey—from dinosaurs to DNA to comets to dark matter and to past and future of our species. Randall's research is so thorough, the story so powerful, and her storytelling so compelling that I could not put this book down.'' --Siddhartha Mukherjee, author of

On Dark Matter sending the Meteoroid that Killed dinosaurs

This is an original, unique, well written and researched book by Dark Matter physicist Lisa Randall. Not only does she explain a subject that mainly experts in her specialty know , discuss about and rarely publish for the general public. This book suggests an interesting hypothesis that the meteroid that killed the dinosaurs 66 million years was triggered by the dark matter disk in the centre of the galaxy. This book also covers in details a variety of different fields but related in her hypothesis. In the first section of the book, it provides how dark matter was discovered and its importance. Dark matter is 85% of the universe which means that percentage of the universe is not visible and unknown to us other than accountable by gravitation of the universe. Randall also explains dark matter provided the required gravitational collapse into galaxy and stars in the early universe that ordinary matter alone couldn't not complete because dark matter is unaffected by electromagnetic radiation. It is instrumental to structuring the universe and also provides the mass to maintain the current universe. In part two of the book, it is basically a nicely written astrophysics introduction to asteroids and comets. Randall explains the asteroid belt between the outer planets and inner planets, and the Oort Cloud 1000 AU times the distance between earth and sun where many comets originated from and where the K-pg boundary extinction comet likely came from. In this section a history of various meteorites impacted the earth was presented and its interesting effects and frequencies. It makes fascinating reading if you are interested in meteroids history and destructive power, and extinction events. Randall also discussed the periodicity of asteroids and comets, and that the solar system has a period of 35 million years of travelling thru the dark matter disk in the centre of the galaxy where the Oort could experience dark matter gravitational effects. In part three of the book, R...
