# My new paper on black holes

I am a little bit late to celebrate Einstein’s birthday. But here is my new paper that extends Einstein’s 4-d General Relativity to a 2-d spacetime model with new understanding and studies the black hole as a genuine 2-d object. Unfortunately,  arXiv did not help again this time and put my submission on hold one more time. Most likely, they are going to reject it again like my last paper in a few weeks.

The new model predicts a neutron/quark star mass limit of less than 2.5 solar mass that is compatible with observation. For more massive stars, the ever softer equation of state in 4-d spacetime will eventually cause a core collapse to a temperature above 1016 GeV. The 4-d spacetime then undergoes phase transition to 2-d spacetime with much reduced degrees of freedom to re-stabilize the star as a true 2-d black hole.

With new understanding of gravity as a mean field theory emergent from the underlying quantum theory for providing smooth background spacetime geometry for quantum particles, the black hole interior can be described well as a perfect fluid of free Majorana and boson particles in 2-d conformal field theory on a torus.

Here is the title and abstract of the paper:

##### From neutron and quark stars to black holes

New physics and models for the most compact astronomical objects – neutron / quark stars and black holes are proposed. Under the new supersymmetric mirror models, neutron stars at least heavy ones could be born from hot deconfined quark matter in the core with a mass limit less than $$2.5 M_\odot$$. Even heavier cores will inevitably collapse into black holes as quark matter with more deconfined quark flavors becomes ever softer during the staged restoration of flavor symmetry. With new understanding of gravity as mean field theories emergent from the underlying quantum theories for providing the smooth background spacetime geometry for quantum particles, the black hole interior can be described well as a perfect fluid of free massless Majorana fermions and gauge bosons under the new genuine 2-d model. In particular, the conformal invariance on a 2-d torus for the black hole gives rise to desired consistent results for the interior microphysics and structures including its temperature, density, and entropy. Conjectures for further studies of the black hole and the early universe are also discussed in the new framework.

As a research professor at Notre Dame, I share my ideas and thoughts mainly about mirror matter theory and open science on this blog. Under the new theory, we live in the universe with a mirror (hidden) sector of particles. A perfectly imperfect (minimally broken) mirror symmetry is the key to unlock the beauty and elegance of our universe.

Both arXiv and PRL’s editor rejected this paper on black holes today. Notice that they did it almost simultaneously (within an hour, one day after the submission). Interestingly, both arXiv and PRX’s editor rejected my last paper of SUSY mirror models on the same day as well (two weeks after the submission). Could it be just a pure coincidence or a collaboration between the services? At least they are much more efficient this time.
