Black holes have long been a fairly enigmatic entity within our universe . Discovered in the '60s, the first black hole wasn' t formally confirmed until the '70s. And it wasn' t until 2019 that we saw the first image of a black hole . But it turns out there are likely a lot of them. A team of scientists at Scuola Internazionale Superiore di Studi Avanzati studying the demographics of stellar mass black holes are releasing a series of papers with their findings, and their first paper delivers a supernova-sized bombshell. In their (very well-studied) estimation, our universe has 40 billion billions of black holes.

[...] There are 40 billion billion black holes in the universe, according to new research done by Alex Sicilia at Italy' s Scuola Internazionale Superiore di Studi Avanzati and colleagues. This means that about 1% of the normal matter in the universe is bound up in black holes - something that team says is a 'remarkable amount'. In the above video, colleague Lumen Boco explains how the team came up with that astonishing number.

Câte guri negre exist în Univers? Aceasta este una dintre cele mai relevante i apstoare întrebri din astrofizica i cosmologia modern. Aceast întrebare a fost abordat recent de doctorandul Alex Sicilia, sub îndrumarea prof. Andrea Lapi i dr. Lumen Boco, alturi de ali colaboratori din instituii naionale i internaionale. [...] Acest rezultat important a fost obinut datorit unei abordri originale care combin codul de evoluie stelar i binar de ultim generaie SEVN, dezvoltat de Dr. Mario Spera, cercettor SISSA [...].

Es bien sabido que ciertamente no todos los trabajos son iguales: existen los trabajos más exigentes, que dan derecho a la jubilación anticipada , y los considerados no exigentes y que también se pueden realizar a partir de los 65 años. [...] Esto se ejemplifica en un estudio realizado conjuntamente por la Escuela Internacional de Estudios Avanzados (SISSA) y la Universidad de Padua, publicado posteriormente en el European Journal of Neurology [...].

Sebuah tim astrofisikawan telah menghitung jumlah bintang massa lubang hitam di alam semesta teramati menjadi 40 triliun, terhitung 1% dari total materi biasa di alam semesta. [...] "Karakter inovatif dari karya ini adalah untuk menggabungkan model rinci evolusi bintang dan biner dengan resep canggih untuk pembentukan bintang dan pengayaan logam di galaksi individu," kata Alex Sicilia, astrofisikawan di SISSA di Italia dan penulis utama makalah, di sebuah institut.

Há 40.000.000.000.000.000.000.000 buracos negros no Universo, que constituem aproximadamente 1% de toda a matéria observável. Os buracos negros são um dos maiores pontos de interrogação da Astronomia. Contudo, se os cientistas soubessem quantos existem no Universo, poderia ser mais fácil responder a algumas questões que ainda carecem de resposta. A Escola Internacional de Estudos Avançados (SISSA), em Itália, investigou a demografia dos buracos negros de massa estelar [...].

We do not know how far the universe stretches in space, but we do know how to estimate the size of what is called the observable universe. [...] Indirect ways to estimate these numbers and today we have a team Astronomers Conducted by members of the International School for Advanced Studies (in Italian, International School of Advanced Studies Or SISSA), a well-known Italian university located in Trieste, has published an article estimating the number of star-shaped black holes in the observable universe.

Tým astrofyzik vypoítal poet hvzd erné díry v pozorovatelném vesmíru mají hmotnost 40 kvintilion, co je 1 % celkové bné hmoty ve vesmíru. Vdci se zamují na erné díry s hvzdnou hmotností, nejmení známou skupinu, ale poznamenávají, e jejich výpoty by mohly pomoci vyeit prastarou záhadu, jak se supermasivní erné díry íí. [...] Lumen Boco, také astrofyzik v SISSA a spoluautor lánku, ve stejné zpráv uvedl, e výpoty týmu by mohly slouit jako výchozí bod pro zkoumání pvodu tkých semen', co budeme dále sledovat nadcházející noviny."

Scientists have estimated the number of "small" black holes in the universe. [...] So how did the scientists arrive at that number? By tracking the evolution of stars in our universe they estimated how often the stars - either on their own, or paired into binary systems - would transform into black holes, said first author Alex Sicilia, an astrophysicist at the International School of Advanced Studies (SISSA) in Trieste, Italy.

The thought of one or two black holes out there in space is mildly terrifying. But what if we told you that there far more than that?In fact, according to a new study from the International School for Advanced Studies in Italy, there are, in fact, 40,000,000,000,000,000,000 black holes out there.

A team of astrophysicists has calculated the number of stellar- mass black holes in the observable universe to be 40 quintillion, accounting for 1% of the total ordinary matter in the universe. [...] 'The innovative character of this work is in the coupling of a detailed model of stellar and binary evolution with advanced recipes for star formation and metal enrichment in individual galaxies,' said Alex Sicilia, an astrophysicist at SISSA in Italy and the paper' s lead author, in an institute release .

Met behulp van een nieuwe rekenkundige aanpak hebben onderzoekers van de Scuola Internazionale Superiore di Studi Avanzati (SISSA) in Trieste, Italië, een schatting gemaakt van het aantal zwarte gaten in waarneembare heelal. Ze komen uit ongeveer 40 triljoen oftewel 40 miljard miljard - een 4 met 19 nullen erachter. Tezamen nemen al deze zwarte gaten ongeveer één procent van alle (baryonische) massa in het heelal voor hun rekening ( The Astrophysical Journal , 10 januari).

door Een onderzoeksteam van o.a. de Scuola Internazionale Superiore di Studi Avanzati (SISSA) in Italië heeft recent een berekening gemaakt hoeveel zwarte gaten er in het waarneembare heelal zijn . Daarbij keken ze naar stellaire zwarte gaten, dat zijn de zwarte gaten die het eindproduct zijn van de levens van zware sterren, en die een massa hebben van enkele keren tot honderden keren de zonsmassa.

Innovative Studie Im Universum soll es 40 Trillionen stellare Schwarze Löcher geben. Ausgeschrieben sieht die Zahl so aus: 40.000.000.000.000.000.000. Das entspräche etwa einem Prozent der Masse im einsehbaren Universum. Wie Alex Sicilia von der International School of Advanced Studies (SISSA) erklärt, wurde für die Studie, die im Astrophysical Journal veröffentlich wurde, ein neue Herangehensweise angewandt.

l número de agujeros negros en el Universo observable (una esfera de un diámetro de alrededor de 90.000 millones de años luz) en la actualidad es de unos 40 billones, es decir, 40 millones de millones. La investigación ha sido abordada por el estudiante de doctorado de SISSA (Scuola Internazionale Superiore di Studi Avanzati) Alex Sicilia, supervisado por la profesora Andrea Lapi y la doctora Lumen Boco, junto con otros colaboradores de esta centro italiano y de otras instituciones nacionales e internacionales.
