{"product_id":"9783832531867","title":"Causality-Violating Lorentzian Manifolds Admitting a Shear-free Timelike Flow","description":"\u003cp\u003eThe Godel spacetime is an important cosmological solution of Einstein's field equations of gravitation. Although it does not offer a viable description of the physical universe, it illustrates the theoretical possibility of time travel. This work investigates world models similar to the Godel spacetime with particular emphasis on relations between kinematical properties (shear, vorticity, acceleration, expansion) and causality violation, i.e., the formation of closed timelike curves.\u003c\/p\u003e","brand":"Logos Verlag","offers":[{"title":"Default Title","offer_id":47059824935152,"sku":"9783832531867","price":51.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9783832531867_p0.jpg?v=1763687814","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9783832531867","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
