As per usual rajish, I'm now not sure what you are claiming, and obviously neither do some of the members over at that other place.

You appear to be now back tracking from your original claim that

For all,

No 'certain density' is required for black hole formation. For a BH defining density is meaningful only when object is just at EH and about to collapse to form BH. At this point an object can have any density, from as high as nuclear to as low as near vacuum. The condition is that it's mass should fall within its schwarzschild radius, at this point density of the object is inversely proportional to mass squared. Higher the mass, lesser density and vice versa.

Squeeze the mass of the Earth to within the radius of a pea.....guess what? The density is such that the Earth becomes a BH.

Squeeze the mass of the sun to within a radius of 2.5 kms...guess what? The density would be such that the Sun would become a BH.

While the density of any BH is virtually a meaningless concept, the density of the mass causing the spacetime curvature, up to and including the EH, is not, and also the density required to reach the Schwarzchild radius is paramount in BH formation.

The density of the BH once it is formed is another story as I have just said.....That density of course lies at what GR tells us is the Singularity, and where densities and spacetime curvatures approach infinity.

Again, you are also incorrect re your fabricated version of events at the EH. That density by definition and in line with GR, needs to be such that the escape velocity equals "c" as I have detailed.

No amount of confusing obfuscation will change that fact.

Again, to speak of density of a BH is really meaningless, because the

**mass/density exists only at the singularity core.**..the rest of the BH is just critically curved spacetime out to the EH.....so the density of a SMBH could certainly be less then water:

**Do you understand?**
But for any

**BH to form**, it must reach a

**certain mass/density dictated by its Schwarzchild radius.** Once that happens, further collapse as dictated by GR is compulsory.

**Do you understand?**
So we have two issues which you are conflating, but which are separate issues...BH density, and density associated for a BH to form.

Let me again repeat myself and make it quite clear........

Now again if you are claiming anything different to what I have said than please supply a reputable reference or link supporting your claim.

To keep on ignoring this reasonable request, and carrying on with your obfuscation, simply amounts to trolling.
