If Black holes do not exist, would string & LQG be falsified? Suppose that black holes do not exist in nature, in that the quantum properties of matter prevents density from increasing beyond a certain limit, as well as gravity's strength diminishing at higher energies. Stellar objects can collapse up to a certain density before new previously unknown physics takes over. GR becomes invalid a description of BH beyond a certain range of distances. One paper for example, http://arxiv.org/ftp/astro-ph/papers/0503/0503200.pdf speaks of dark energy stars There is no hawking radiation as they apply to BH, no information loss. "Dark stars" follow the usual entropy laws, adding energy increases its heat, losing energy cools it off (BH follow the reverse) Instead of singularities and infinite densities, dark stars undergo a phase transition analogous from solid to liquid. If the above were true, would it falsify string theory and LQG, which of course, both predict BH's (but not dark energy stars) and BH entropy.
