Default BH density

In my wanderings and wonderings, I came up with this.

In a BH surrounding, what happens when R causes g = Esc vel?

All in meters, when R(Mc^2/2)^1/3, it seems that g tips over esc vel.
A paradox, or does the density of 7155613462.48462 kg/m^3 have some
significance?

And related. Is it accretion rate (or type of material in the
accretion) that differentiates whether a neutron star explodes or can
go to BH?

I always want to know everything. Thanks for reading this.

Another fine example of a meaningless question. What are you using R to
represent, scalar curvature? What's g? What's a "BH surrounding"? Nonsense.

xxein: What's G_00? What's i,j,k? What's curvature? What'sa matta wich you?

If you really hadn't a clue, then why did you post a response? NOW THAT'S NONSENSE!

This does not make sense. g is an acceleration[#} and escape velocity is
a velocity, so they are incommensurate and cannot be compared[%] or
approach each other [@].

[#] Assuming you're implicitly sing a Newtonian analogy, even
though that is well known to be invalid for a black hole.
Without this I have no idea what your g might be.

[%] interpreting "=" as "equal to or greater than".

[@] interpreting "=" as an arrow meaning "approaches".

In the future, please refrain from excessive abbreviation, and please
define your terms.

I'm ignoring the problem of guessing what your "R" means....

Based on the utter lack of responses to your question, surely you can see
that others had the same problems in trying to interpret exactly what you
meant? Clear posts beget clear and detailed answers.

xxein: I must apologise for my last post. I hope you will accept.

Maybe it is just me, but there seems something wrong or odd about
acceleration due to gravity (g) being of a higher numerical value than
than escape velocity based on radius (r) from the center of a massive
object.

I'll figure something out, sooner or later.
