Is the concept of moving backwards and/or forwards to different points in time through the vagina, or better know as gynowormholes. It is currently unknown whether the laws of physics would allow time travel, through the vagina. gynowormholes are a type of hypothetical warped spacetime which are also permitted by the Einstein field equations of general relativity, although it would be impossible to travel through a gynowormhole unless it was what is known as a traversable gynowormhole.
"Have you proven your chrongyno theory yet? I really want to jump into that Gynowormhole and travel back in time"
