Spontaneously induced general relativity with holographic interior and
general exterior
   [PDF]

Xiao-Qing Shen, Shao-Feng Wu, Guo-Hong Yang
The general relativity (GR) might be viewed as a spontaneously induced theory from the scalar-tensor gravity, in which the would-have-been horizon connects the exterior solution of GR with a novel core of vanishing spatial volume. Using a simple but robust analytic method, we give the nontrivial core metric for the general exterior. Then we show that all the nontrivial features of the core, including the locally holographic entropy packing, are not influenced by the general exterior. We also investigate whether other modified theories of gravity can permit the nontrivial core.
