The results found here show … Webwormholes that are in general not spherically symmetric. Though exotic matter is still present in the region of the throat, it is then possible for a traveller to avoid regions of exotic material in his/her/its traversal of the wormhole. Indeed, it is possible to obtain wormholes and geodesics such that the traveller feels no forces,

Then, we have calculated the shadow of Casimir wormhole. To do so, we have first obtained the null geodesic of the Casimir wormhole and then we have found the apparent shape of a shadow by using the celestial coordinates. germany ivd
