通过Ringhole和Klein-bottle孔观察其他宇宙
Observing other universe through ringholes and Klein-bottle holes
摘要：
有人认为，虽然由球对称虫洞的引力内场产生的Shatskiy单环和由环形环孔产生的同心双爱因斯坦环不能在没有一些不确定性的情况下用于识别宇宙中存在这种隧道或存在平行宇宙，不可定向的克莱因瓶洞隧穿的内部引力场通过透镜作用单个光源而留下的图像是截断的双螺旋的图像，这是一个签名，不能归因于任何其他单一或复合天文物体在任何宇宙中，它可能被放置。在这份报告中，我们论证了更多的理由来预测这样的签名将意味着在我们或其他宇宙中发现一个这样的不可定向隧道。毕竟，一个不可定向的克莱因瓶洞也是爱因斯坦方程的一个完全有效的解，而且使它可行的东西在宇宙学中越来越熟悉。
英文摘要：
It is argued that whereas the Shatskiy single rings produced by the gravitational inner field of a spherically symmetric wormhole and the concentric double Einstein rings generated by a toroidal ringhole could not be used without some uncertainty to identify the presence of such tunnelings in the universe or the existence of a parallel universe, the image which the inner gravitational field of a non orientable Klein-bottle hole tunneling would leave by lensing a single luminous source is that of a truncated double spiral, which is a signature that cannot be attributed to any other single or composite astronomical object in whichever universe it may be placed. In this report we argue some more reasons to predict that such a signature would imply the discovery of one such non orientable tunneling in our or other universe. After all, a nonorientable Klein-bottle hole is also a perfectly valid solution to the Einstein equations and the stuff which would make it feasible is becoming more and more familiar in cosmology.
