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.
/ Book: ''' Stephen Hawking. A life in science '' by Michael White and John Gribbin/
#
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.

And what topic in the philosophy of science are you opening for discussion?

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☉.

Dang it. I had a comment about where to find black holes.

Carry on.

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?

socrat44 wrote: ↑Sat Sep 24, 2022 9:36 am with masses greater than 100 billion M☉.

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?

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.

1- A black hole has a temperature within a few millionths
of a degree above absolute zero
/ Oxford. Dictionary./
2- A stellar black hole of one solar mass has a Hawking temperature
of about 100 nanokelvins. This is far less than the 2.7 K temperature
of the cosmic microwave background Black hole
/Wikipedia/
3- A black hole of one solar mass (M☉) has a temperature
of only 60 nanokelvin (60 billionths of a kelvin)

2. The difference in temperature is just because one measurement is being taken at the in-TAKE while the other temperature is taken of the out-BURST.

Temperature is simply an interaction between particles that is caused by energy

Temperature is simply an interaction between particles that is caused by energy

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.

BUT, so what?

there is difference between EM energy and thermal energy

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?

if these vacuums exist, is it god who empties the vacuum bags?
