MECO and black holes?

[Dancing David]

This is another split from the plasma cosmology thread:

There is the concept of the magnetospheric eternally collapsing object. Suggested by an astrophysicist Abhas Mitras and later used by Schild to explain observation of a quasar Q0957+561.

Does this make sense? It seems to. Except that it says that black holes never collapse to a singularity but radiate away all thier mass.

The total mass energy of a MECO (or anything) is E = Mc2 and it is losing energy as per Eq.(4). Then it follows that, its observed time-scale at a given z=z is

t(observed) = E/L ˜ 4. 108 (1+z) yr ...(8)
This time scale has recently been termed as "Einstein -Eddington" time scale [17].

As the MECO evolves to approach , naturally,

t(observed) → ......(9)
This explains the rationale behind the phrase ``Eternally Collapsing Object". During this infinite journey towards the true BH state, a MECO burns its entire mass into energy/radiation and hence the eventual BH has M=0.

there is also the issue of the magnetic field which appears to be anchored in a spinning object which is part of why it is not a black hole.

Thus, the observations of the accretion disc of this quasar made with the aid of a gravitational lens seem to indicate that Q0957+561 has a magnetic field, which a black hole cannot have. The researchers deduced the existence of a magnetic field from the fact that the accretion disk has a gap of 4000 AU around the central object.

I'm pretty sure the Bad Astronomer had an article on this recently. I'll see if I can find it.

Well, that was easy. Here it is.

I imagine the laws of physics simply become less time dilated as you move out from the singularity (which doesn't actually exist in nature, much as how thermodynamic absolutes are approached, but never attained).
