Title: Observing other universe through ringholes and Klein-bottle holes
Authors: Pedro F. González-Díaz, Ana Alonso-Serrano

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 tunnelling 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 tunnelling 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.

The dusty boxes that line the walls of Jeff Barrett's UC Irvine office mark a high point in his academic career. Their contents: pages and pages of notes, most more than 50 years old, penned by late quantum theorist Hugh Everett III.
With $160,000 from the National Science Foundation, Barrett and colleagues are combing through, scanning and preserving documents they hope will shed light on how to understand measurement as a consistent physical process in quantum mechanics - one of physics' most debated puzzles that Everett believed he had solved as a graduate student.

Stick your finger in your ear... Did you do it? If the so-called Many Worlds Interpretation of quantum mechanics is correct, there's at least one universe in which you did, one in which you didn't, and universes for everything in between. Physicist Hugh Everett III was just 27 years old when he introduced this interpretationalso known as the theory of parallel worldsin the published version of his 1957 doctoral thesis. According to Everett's theory, every event that could occur in a number of ways, even something as simple as how you decided to respond to the above request, triggers a split that generates multiple universes, which collectively contain every possible outcome. While new to science, the notion of parallel worlds was hardly new to science fiction.
