Both the right and wrong mechanisms are explained. \u003cp\u003e\u003c\/p\u003eThe important 1919 Eddington Experiment is reviewed. \u003cp\u003e\u003c\/p\u003eThis book will reference many galaxies and galaxy clusters. Rather than bringing color images into this black and white book, a reference web page provides links to original source files with their high-resolution images. \u003cp\u003e\u003c\/p\u003eThe title implies there are observations associating an illusion with a gravitational lens. A gravitational lens is based on a simple assumption, that either the force of gravity or curvature of space-time can bend the path of light, \u003cp\u003e\u003c\/p\u003eThe requirements or conditions for this assumption must be clearly defined. This book describes several scenarios with specific requirements. Given the same scenario, another mechanism is described that explains how the path of light can be bent, but not by gravity or space-time.\u003cbr\u003eIf the requirements for a gravitational lens are not met, then the gravitational lens conjecture must be discarded, and an alternate mechanism is provided based on the specific conditions of the observation. \u003cp\u003e\u003c\/p\u003eThis is the scenario when the observed behavior is real, but unexpected. Therefore, a gravitational lens is invoked incorrectly to claim the lens caused the observation. By invoking a lens, the observation must be an illusion, not real. \u003cp\u003e\u003c\/p\u003eA gravitational lens is the simple excuse when an observed behavior in distant galaxy clusters cannot be explained, because the behaviors of plasma physics were ignored. \u003cp\u003e\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e David Michalets\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9798780362425\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 12\/08\/2021\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 112\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.35lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.23d","brand":"David Michalets","offers":[{"title":"Paperback","offer_id":47419726790911,"sku":"9798780362425","price":7.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_c104f2cb-06a0-493b-9038-a4d2fb661404.jpg?v=1761513465","url":"https:\/\/www.whiterainbookhouse.com\/products\/gravitational-lens-illusions-david-michalets-9798780362425","provider":"WR Book House","version":"1.0","type":"link"}
