Possible wormholes in generalized geometry-matter coupling gravity induced by the Dekel-Zhao dark matter profile

A. Errehymy, O. Donmez, A. Syzdykova +4

In the late 1980s, Morris and Thorne led in theoretical physics by creating solutions to wormholes and formulating the crucial requirements for safe traversability of wormholes. Th…
