ANCIENT BLACK HOLE

Oh no! Not another thread about astronomy ? Yes, and I'm really sorry to be annoying with my second favorite hobby. But if you're not interested, please feel free to read something else. Like the US coins forum. I do this myself regularly when I have difficulty falling asleep; usually after about 3 minutes, I regain sleep ... But back to astronomy. Astronomers have detected a cluster of galaxies with a supermassive black hole at its center dating from the early ages of the Universe, a discovery that helps better understand the formation of these enigmatic cosmic monsters.



The scene, seen by the European Southern Observatory (ESO), takes place when the Universe was not even a billion years old, or 10% of its current age (13.8 billion years): six galaxies are trapped in cosmic filaments similar to a spider's web, grabbed by a gigantic black hole of a billion solar masses, lurking in the heart of the structure. We used to think that they were small and that they grew over time, over 13 billion years. But finding them so early in the history of the Universe shows that they have evolved much faster. How is this rapid growth possible? The study suggests that the immense web of filaments and the galaxies that cluster in it contain enough gas to provide the "fuel" the black hole needs: by devouring the gas from the filaments of the main galaxy (the one that does possesses the most) at the heart of which it lodges, it transforms itself into a cosmic giant in accelerated fashion. These discoveries make us all feel very small in this immense universe ...

Now let's find a link with numismatic. I do not believe there is a coin featuring a black hole on it. But the Thread's title is Ancient Black Hole...So in honor of this important discovery, please show us coins that are Ancient or Black or Holed !

Ancient Black Crispus

Now you did it!!! You can be sure that as soon as someone from the Mint sees this (they're running out of ideas for new dollar coins ) in a couple of years, we'll see this new series titled "50 Largest Black Holes of the Universe".

DON'T POKE THE BEAR (or the Mint)!!!

 

When we look deep into the Universe we may be seeing the same galaxies at different stages of their life and not realize it. Astronomy is one of my favorite hobbies. But, I don't believe everything the dogmatic PHD's say. If they try to push something different they may be out of work. I need a brand new pad of stickies when I open a new book on Astronomy, Astrophysics, Cosmology, Cosmogony, so I can mark all the contradictions. Not contradictions with my thoughts, but from page to page in the book. But, it is fun for me.

Interesting discovery to be sure...

A coin of Constantine.. which like the OP coin, features a sunburst in exergue.. seeing that the sun is a star - lets call it a starburst .. to tie in with this post..

Obv: CONSTANTINVS AVG, laureate head right.
Rev: D N CONSTANTINI MAX AVG, VOT XX within wreath
Mintmark: Epsilon SIS sunburst

Here a black coin of the son Constantius II...

Black son = black sun = black star.. a gravitational object composed of matter. It is a theoretical alternative to the black hole concept from general relativity. ... It will appear almost exactly like a black hole.

I really had to work to tie this in....

Obv: CONSTANTIVS P F AVG - Diademed, draped and cuirassed bust of Constantius II.
Rev: VICTORIAE DD AVGGQ NN - Two victories, facing each other, each holding wreath and palm; Leaf between, TRS in ex. (Trier mint).

 

Hi,

Does anyone have the Byzantine hystamenon of Constantine IX showing the supernova that created the Crab Nebula?

Thanks, great reading.

 

Fascinating write up.

here are two "orbiting" black holes of mine - father and son...
Dupondius of Vespasian with satellite black hole sestertius of his son Titus...

 

This video of the Crab nebula pulsar was taken over a nine month period.


And an ancient, black and holed coin.

But isn't each specific galaxy in the relatively same position (from us, as observers) regardless of what stage of its life it may be in? How would we see it anywhere else because of its age? I think the only way we will ever see a galaxy in a different stage of its life is when the Webb telescope is finally up and working, and its images can be compared to what the Hubble can capture, but even then a specific galaxy will be in pretty much the same position from our point of observation.

(The rambling thoughts of someone who loves the ideas and is totally lost on the science).

Now to tie a black(ish) coin into all this...

 

Ancient and black, with 1.5 holes.


CONSTANTIUS II
AE3, Holed. 2.27g, 18.3mm. Antioch mint, AD 324-325. RIC VII Antioch 60 (R2). O: Laureate, draped and cuirassed bust right. R: CONSTAN / TI • VS / CAESAR in three lines; SMANTΔ / • below.

 

a coin with a lot of character... really nice!

Everything is in motion. When we look into space, we are looking back in time. The further away an object is, the further back in time it is. The best way I've found to come to grips with this conundrum is to look at the visible universe like the concentric layers of an onion where each layer represents a snapshot of the universe at a particular time in the past. How the various layers relate to one another is a much more difficult question. I'm having a little trouble conceiving how an object might appear to us simultaneously from different apparent positions and different time-layers of the onion. The object would have to have effectively moved (in an admittedly Newtonian sort of way) at greater than than the speed of light between those two apparent positions. But then again, I'm having trouble wrapping my mind around all sorts of things these days.

 

It is difficult to understand any of this. There is too much dogma that interrupts our thought processes. I was thinking that we see the light that we are intercepting today. With the gravitational curvature light would have travelled in all directions from a galaxy and we could be seeing it in a younger (or older) state in a completely different direction.

 

The classical example of gravitational curvature as predicted by general relativity is that of the sun passing in front of a distant object. The sun's gravitational field briefly deflects the light that is coming toward us from that object in an ever so slight but measurable way as it passes. The beauty of science is that it is a collective effort and everyone need not start from scratch.

I love the smooth black patina on this one!

Notes: Cohen 122 (Wiczay): "Concordia? standing l., holding statue and wand," (La Concorde? debout à gauche, tenant une statuette et une baguette) is almost certainly a badly described specimen of this type.

 

A black'n from Spain...

Black Titus with highlights


I understand as ditsrq says, we are looking in the past of all these objects in the sky. Does that mean that some of these objects are now destroyed in real time ?

 

Another fantastic thread idea O man!!!
My fav black coin has gotta be livia (these things are so hard to get a good pic of that I'll share the sellers pic so you can enjoy the black beauty):


And my most holy coin had got to go to this Doge:
