hurrycane Posted July 13, 2015 Share Posted July 13, 2015 Recently I watched a couple of fun YouTube videos on Klein bottles. In one of them https://youtu.be/4XN0V4xHaoQ the Mathologer, a math professor I think, talks about the mathematical possibility of a universe being shaped like a 3d counterpart of a 2d Klein bottle surface. That would mean that somebody living in such a universe could turn himself into his mirror image by travelling along certain closed paths. Is there anything in physics that would indicate that such mirror-reversing paths are or are not present in our universe? Link to comment Share on other sites More sharing options...
imatfaal Posted July 13, 2015 Share Posted July 13, 2015 We don't see right handed neutrinos nor left handed anti-neutrinos (presuming they are not majorana particles) - surely we would expect that some of the neutrinos we detect would have been flipped in their helicity/chirality by these strange paths Link to comment Share on other sites More sharing options...
