<p>[QUOTE=&quot;Ocatarinetabellatchitchix, post: 4902222, member: 99554&quot;]Oh no! Not another thread about astronomy ? Yes, and I&#039;m really sorry to be annoying with my second favorite hobby. But if you&#039;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 ...<img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie104" alt=":yawn:" unselectable="on" unselectable="on" /> 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.</p><p><br /></p><p><img src="https://m1.quebecormedia.com/emp/emp/c955e110-03b3-11eb-8277-dbd810421df0_ORIGINAL.jpg?impolicy=crop-resize&amp;x=0&amp;y=0&amp;w=0&amp;h=0&amp;width=1936" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> </p><p><br /></p><p>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&#039;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 &quot;fuel&quot; 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 ...</p><p><br /></p><p>[ATTACH=full]1182818[/ATTACH] </p><p>The European Southern Observatory</p><p><br /></p><p>Now let&#039;s find a link with numismatic. I do not believe there is a coin featuring a black hole on it. But the Thread&#039;s title is Ancient Black Hole...So in honor of this important discovery, please show us coins that are <b>Ancient</b> or <b>Black</b> or <b>Holed</b> !</p><p><br /></p><p><b>Ancient Black </b>Crispus</p><p>[ATTACH=full]1182817[/ATTACH] </p><p><b>Ancient Holed </b>Commodus</p><p>[ATTACH=full]1182816[/ATTACH][/QUOTE]</p><p><br /></p>
