Abstract:<\/b>
\nA new concept of beamed propulsion by a remotely transmitted beam of gravitational waves (GWs) is introduced. Its theoretical possibilities are investigated within the framework of the theory of general relativity and a weak energy condition. Under the assumption that the artificially controlled beaming of gravitational waves is possible, it is demonstrated that the flight time of a spacecraft can be reduced while it travels across the area of influence of a GW beam. Two different kinds of GW-beam solutions are considered: First, a Gaussian beam solution, which satisfies the linearized Einstein equation in vacuum approximate solution, is introduced. As a result, flight-time saving is possible using a linear Gaussian beam while a beam solution of finite strength violates the weak energy condition. Second, it is demonstrated that flight-time saving can be achieved by using a non-linear wave packet which exactly satisfies the Einstein equation in vacuum and the energy conditions outside the source of the gravitational waves.<\/p>\n","protected":false},"featured_media":8945,"template":"","meta":[],"pwb-brand":[],"product_brand":[],"product_cat":[56,59,161],"product_tag":[2142,2141,1487],"class_list":["post-8944","product","type-product","status-publish","has-post-thumbnail","product_cat-journal-of-the-bis","product_cat-papers","product_cat-2011papers","product_tag-gravitational-waves","product_tag-k-mori","product_tag-propulsion","first","instock","downloadable","virtual","purchasable","product-type-simple","czr-hentry"],"jetpack_sharing_enabled":true,"brands":[],"_links":{"self":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product\/8944","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media\/8945"}],"wp:attachment":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media?parent=8944"}],"wp:term":[{"taxonomy":"pwb-brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/pwb-brand?post=8944"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_brand?post=8944"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_cat?post=8944"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_tag?post=8944"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
