The matter free regime what can be said Here I raise the question of what happens when all of the matter is squeezed away or converted to energy existing only as radiation near where an event horizon would form assuming for the moment that is possible What are the properties of energy in the matter free regime There is clearly a rationale for a push back or back reaction due to the effusive nature of energy and its resistance to compression The Eddington limit provides a clear mechanism by which inward and outward forces can be equalized to resist further infall but a question arises of whether there is a point where we observe what could be called the liquefaction of energy such that it behaves like an incompressible fluid past that point There also is a rationale for an absolute limit to the compressibility of energy ref S K Kauffmann C Schiller which controverts the notion that energy is uniformly like a photon gas regardless of how it is squeezed or stretched This of course introduces non Maxwellian terms and or non linear Electrodynamics abbrev NLED I shall be adding a paragraph to the section on observational and theoretical developments and some links to papers relating to NLED effects on black hole dynamics As it turns out there is a common thread with the topic of MECOs in terms of a common pool of ideas and a cross over of researchers with the NLED Black Hole group I have in mind citing a paper by Christian Corda and Herman Mosquera Cuesta to illustrate this connection so that Wikipedia readers can see there has indeed been a filtering of the ideas shaping the MECO concept into the mainstream of Black Hole research even if the terminology and lineage of that work is not being preserved I would guess that some researchers who were influenced by the work of Abhas Mitra or that of Leiter Robertson and Schild lack the courage to speak up on their behalf but still draw inspiration from their ideas and seek other ways to validate those concepts It is far easier it seems to validate the halt of collapse using Quantum Mechanical fluctuations as the rationale than it is to show that the same dynamics can be achieved by modifying Classical Electrodynamics by including non linear terms which experiments show are required
