Observing other universe through ringholes and Klein-bottle holes

TL;DR

The paper proposes that lensing signatures from non-orientable Klein-bottle holes could uniquely indicate their presence in the universe, providing a new way to observe and identify such exotic tunnelings and potentially other universes.

Contribution

It introduces the concept that Klein-bottle holes produce distinctive lensing signatures, specifically truncated double spirals, which are unique and could confirm their existence.

Findings

Klein-bottle holes produce unique lensing signatures.

Such signatures are distinguishable from other astronomical objects.

The existence of Klein-bottle holes is consistent with Einstein's equations.

Abstract

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.
