Dark Matter and the Dinosaurs

Posted on 17 April 2017 by Lisa Randall

Bestselling author of Warped Passages and Knocking on Heaven s Door and one of today s most influential and highly cited theoretical physicists, Professor Lisa Randall once again effortlessly delivers fascinating science to the general reader Weaving together the cosmos history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.Sixty six million years ago, an object the size of a city descended from space to crash into Earth, creating a cataclysm that killed off the dinosaurs, along with three quarters of the other species on the planet What was its origin Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas In a sense, it might have been dark matter that killed the dinosaurs.With her unique and wide ranging perspective, Randall connects dark matter to the history of the world in the broadest terms Bringing in pop culture and social and political viewpoints, she shares with us the latest findings established and speculative regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life s development and extinctions Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us It s impossible to read this book and look at either Earth or sky again in the same way.

souls might in fact be made of dark matter According to our latest models, they dark souls condense first and allow life to settle down around them Of course, they can t be detected since they are not detectable by ordinary matter science On death, the souls depart from the body, and can go to heaven cause rebirth via re agglomeration depending on religious practices of the ordinary matter person associated with the soul It Our Souls are DarkIt is an increasingly accepted speculation that souls might in fact be made of dark matter According to our latest models, they dark souls condense first

cause rebirth via re agglomeration depending on religious practices of the ordinary matter person associated with the soul It is not yet fully understood how religious practices affect the dark matter core of a person However, we do know that the souls get affected by a lifetime of sins, penance, charity, etc It is accepted by now that no life can form without a dark soul though some scientists still like the older idea that a soul is required only for higher life forms, probably only humans Lower life forms can agglomerate without the gravitational religious pull exerted by the soul core

us how she has come to think that there s a connection between galactic dark matter and Earth s periodic extinctions a somewhat long shot hypothesis she takes us in an amazing tour of our Solar System

explain the demise of the dinosaurs 66 million years ago She argues that the solar system passing through a disk of dark matter in the galactic plane perturbed Oort cloud objects resulting in a large

edge of theory as much as a non scientist reader like myself, who reads pop science magazines, can comprehend National Academy of Sciences member Lisa Randall s book was published in 2015 Dark Matter

the first to warn her reader that her new hypothesis is speculative and in need oftesting However, she is excited about the kinds of questions this new direction is taking her Randall has been investigating how dark matter might be involved in not only the creation of matter itself, but possibly in the evolution of humans as well The presence of dark matter is not at all speculative It has been detected using a variety of tools and methods What is speculative is the notion Randall is the first to warn her reader that her new hypothesis is speculat...I picked this up after NPR s Science Friday recommended it I found it diffuse Which is odd given Randall s core thesis that science is exciting when findings from one field cross fertilize an unrelated field and positively amazing when

to the extinction of the dinosaurs Instead, the prop I picked this up after NPR s Science Friday recommended it I found it diffuse Which is odd given Randall s core thesis that science is exciting
