{"product_id":"9781848165328","title":"Physics of the Universe","description":"\u003cp\u003eThis book presents a new approach to the subject of cosmology. If fully exploits Einstein's theory of general relativity. It is found that the most general formal expression of the theory replaces the (10-component) tensor formalism with a (16-component) quaternion formalism. This leads to a unified field theory, where one field incorporates gravitation and electromagnetism. The theory predicts an oscillating universe cosmology with a spiral configuration. Dark matter is explained in terms of a sea of particle-antiparticle pairs, each in a particular (derived) ground state. This leads to an explanation for the separation between matter and antimatter in the universe. There is a brief discussion of black holes and pulsars. The final chapter delves into philosophical considerations such as the different types of 'truth', positivism versus realism and a discussion of the role of the Mach principle in physics and cosmology.\u003c\/p\u003e","brand":"Imperial College Press","offers":[{"title":"Default Title","offer_id":47038108631280,"sku":"9781848165328","price":65.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781848165328_p0.jpg?v=1763749730","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781848165328","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
