Is the 2008 NASA/ESA double Einstein ring actually a ringhole signature?
arXiv:1001.3778
Abstract
It is argued that whereas the Shatskiy single rings produced by the gravitational inner field of a spherically symmetric wormhole could not be used 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 ringhole with toroidal symmetry would allow us to detect from a single luminous source is that of two concentric bright rings, and this is a signature that cannot be attributed to any other single astronomical object in whichever universe it may be placed. At the beginning of 2008 the NASA/ESA Hubble Space Telescope revealed a never-before-seen phenomenon in space: a pair of glowing rings, one nestled inside the other like a bull's-eye pattern. It is also argued that such a discovery may well be attributed to the first astronomical ringhole found in the universe. After all, a ringhole is a perfectly valid solution to the Einstein equations and the stuff which makes it possible is becoming more and more familiar in cosmology.
