Only in 2011 Poplawski pointed out that torsion can stabilize them without exotic matter. Yes on condensed matter, see scielo.br/… | |

| Feb 6, 2015 at 3:00 | comment | added | Ooker | Thanks for your answer. In the Avoidance of singularities section, it says that from the Einstein - Cartan theory, we can build a wormhole inside black hole. So I guess the wormhole is one of successful things in unsuccessful things of Einstein, right? And what about the crystals in the last paragraph? Are they the crystals in condense matter physics? | |
