DESCRIPTION:How would the universe look like when all matter would be in t
 he form of one big rock? This question could have been addressed by Einste
 in himself when there would have been a reason for it. The crucial realiza
 tion is that this corresponds with the Higgs phase of gravity\, a close co
 usin of the Higgs phase in Yang-Mills theory. At the same time\, the geome
 tric interpretation of elasticity has been flourishing in soft matter and 
 material science where all the machinery is lying ready to merge it with g
 ravity. This revolves around the intricate topological excitations of soli
 ds – dislocations\, disclinations etcetera – that turn in a dynamical 
 background into gravitational fluxoids\, the analogues of the Abrikosov fl
 ux lines in superconductors.\n\nReference.\n\n1. J. Zaanen\, F. Balm and A
