The concept of BH explains the observations. There are certain alternative explainations too, but they have certain issues. Whether it is reasonable or unreasonable to assume that BH's do exist, is a subjective matter.
I've been asking you for those alternative explantions since you started here to no avail.
Again what are they? I mean you are starting to sound like a creationist now.
Simply on reasonable assumptions by learned men educated in that dicspline. Most scientists/cosmologists knowing at this time there is no other explanation, take the evidence to infer BH's. A creationist of course would have another non scientific view.
We do not know about any counterforce beyond NDP etc. As per prevalent theory, this statement appears to be true, but the very fact that a mass can fall below its Schwarzchild radius itself is not proved, satisfactorily. There is no direct evidence for this.p{
Here we go with the creationist type of dismissal again...you know the one, "Aha, but you can't prove it" GR is an overwhelmingly correct theory within its domain, and the compulsory collapse is predicted by GR and we have no reason or contrary evidence to indicate otherwise. And it certainly is proved enough for all Professionals to totally dismiss and BNS nonsense.
Crap. The GR equations (for non spinning/Neutral BH metric) give division by zero at r = 0, not at Planck's level. Planck or Quantum Level has nothing to do with GR equations, they are just numerical values for equations.
Nup , spot on in fact. By predicting total collapse and being a classical theory it predicts its own downfall at the quantum/Planck level.
Still, you could show a reference supporting your claim.....but there is none, is there?
Second part is another speculative crap. What, When and How of QGT are unknown as on date or at the best inconclusive. Dreaming that QGT will explain singularity is naive and defeatist approach.
You seem fond of the word crap, yet offer nothing in return, ignoring the demolished BNS nonsense. Again, a QGT will most likely, as its name infers reveal what conditions are like at the quantum/Planck level.
You disagree...All you need is a reference as your word and say so has been refuted many times, even in this thread.
Another childish and repeative crap. If we know "nothing with certainty about the inside of BH beyond EH" then thats it. It is foolish to say that we can assign charge and spin to inside of EH and in the same breath we say that spacetime inside EH is falling at a speed c or higher.
Oh more name calling, more insults etc...your previous warning must have caused some angst.
As Professor Hamilton has said, Professor Lewis, and Professor Carlip from memory, we most certainly are allowed to assign properties such as spin and charge within the horizon as mainstream accept.EG: Any observed ergosphere, logically infers a spinning spacetime and mass.
To deny that is, well, akin to denying evolution.
Vague statement, what is this subject to other conditions.
Not vague at all and again supported by reputable links that happen to go against your agenda. Spin and charge will in time be negated, the rate depending on conditions.
Another crap.
Theory behind HR mechanism (or process) is valid, but as long as CMBR absortption is there a stellar BH will never evaporate. We do not know when and after how much time CMBR will dilute to the level of nano degrees from a present 2.7 K and even then there is a possibility of equilibrum. Presently all stellar BHs, if any, are absorbing CMBR and increasing in mass.
That word again, crap,
Must be the new flavour of the month.
But again, totally wrong and devoid of any common sense.
Let me state it again. If HR is valid as is accepted, that all BH;s, micro, stellar, and SMBH's will in time be evaporated, just as their spin and charge will be.
Again though my friend, if you are able to refute what I say with a reliable reference, then be my guest.
HINT: The CMBR is not always going to be at its present 2.7K
No generally accepted scientific explanations....all of them
What is pure Spacetime?...Spacetime is spacetime.
In reality the spacetime within a BH will have ingoing matter/energy that has crossed the EH and is on its one way trip to the Singularity region where the mass exists. Otherwise if the BH is entirely dormant, all we have is pure spacetime. Wasn't that easy? It's why as you were told on your previous handle, why speaking of BH density is not really done....I believe Q-reuss even pulled you up on that one, as well as myself.
What is critically curved topology thats exceeds 'c' ? How any topology can exceed 'c' ?
At the EH, the spacetime curvature is such that the escape velocity is "c"
From there on its all downhill, as curvature approaches infinity at the Singularity.
I'm always here to lend a hand when and where necessary.
Sweet dreams!
