Talk:Ellis wormhole

This article ("Ellis wormhole") is said to be an Orphan, but it is linked to by the article "Ellis drainhole". Turningwoodintomarble (talk) 02:54, 14 February 2016 (UTC)[reply]

Sources for these details?

The article needs more detailed source information, in particular citing the source of the detailed mathematics of geodesics and for the dynamic wormhole solution. I'm curious because I'm reasonably confident that the article is in error when it claims that "every circle of latitude is a geodesic": the only case in which dρ/ds=0 remains a solution for all s is when ρ=0 (as can be verified from the geodesic equation for ρ). (Otherwise, that condition merely signals a turning point, as mentioned a few lines later.) That error leads me to mistrust the rest of the conclusions here at least a little!
