About black holes
Book: ''' Stephen Hawking. A life in science ''
''Together with Brandon Carter and Jim Bardeen, Hawking wrote a paper,
published in Communications in Mathematical Physics , pointing out . . .
the team commented, '' In fact the effective temperature of a black hole
is absolute zero . . . . No radiation could be emitted from the hole.''
/ page 156./
But later (!) , . . using concepts of entropy and Heisenberg uncertainty
principle and quantum fluctuations (!) Hawking changed his mind
and wrote that black holes can radiate.

So, in the beginning ( according to calculations) the ''black hole''
had absolute zero temperature (like the Cosmic Vacuum: T=0K) . . .
but . . . thanks to entropy, Heisenberg uncertainty principle and
quantum fluctuations the absolute zero temperature was changed.
Conclusion:
Cosmic Vacuum and black holes are one and the same system.
Black holes are parts of the infinite Cosmic Vacuum.

Re: About black holes
And what topic in the philosophy of science are you opening for discussion?
Re: About black holes
At the core of the Milky Way galaxy, contains a supermassive black hole
of about 4.3 million solar masses.
Supermassive black holes with a mass between 0.1 million and 10 billion M☉.
Some astronomers have begun labeling black holes of at least 10 billion M☉
as ultramassive black holes.
Even larger ones have been dubbed stupendously large black holes (SLABs)
with masses greater than 100 billion M☉.
Some studies have suggested that the maximum mass that a black hole can reach,
while being luminous accretors, is of the order of ~50 billion M☉.

Carry on.
Re: About black holes
What is a, so-called, 'supermassive black hole', by 'some', is just a 'tiny little hole', to "others". But, AGAIN, each to their own.
Absolutely EVERY thing is relative, to the observer.
And, what 'you', human beings, call 'supermassive' and/or 'black' holes, or 'big' bangs, are just NOT, to "others". To some, of 'us', they are just 'holes' and 'bangs', which are ALL JUST DIFFERENT in size and/or shape.
So, in the 'scheme of things' REALLY NOT that big NOR massive AT ALL.
WHY do so-called "scientists" come up with the most unimaginable, but also contradictory, the most emotionally driven names?
It is like that are 'trying to' appear that what they, would have anyway come to eventually, find or discover is somehow TRULY AMAZING.
Does this labeling excite you?
AGAIN, what is with the MOST UNIMAGINABLE, and BORING names, but while also 'trying to' emote some 'awe-inspiring' response?
AGAIN, in the 'scheme of things', NOTHING really exciting AT ALL. Well to some of 'us', anyway.
And, as with a LOT of human being 'studies', they are eventually found to be just False, Wrong, and/or Incorrect, from the beginning.

What is 'it', EXACTLY, 'about black holes', that 'you' want to DISCUSS here?Iwannaplato wrote: ↑Fri Sep 23, 2022 6:53 am And what topic in the philosophy of science are you opening for discussion?
At the so-called 'END' of black holes exist 'singularity', which is, EXACTLY, WHAT and WHERE the WHOLE Universe is said, by some, to have 'BEGUN', and come from.

And, the interaction between particles, is simply what causes energy, and energy simply creates different temperatures, which is depended upon the different kinds of reactions, between particles.socrat44 wrote: ↑Mon Sep 26, 2022 4:58 pmTemperature is simply an interaction between particles that is caused by energyAge wrote: ↑Mon Sep 26, 2022 3:54 am2.

Re: About black holes
I'm still wondering what this has to do with philosophy. It seems like brief introduction to some aspects of black holes. What does it have to do with the philosophy of science? What philosophical issues does this information raise? What goal did you have for sharing this in a philosophy forum?
