  • Introduction to Video Content
  • NASA has recently discovered an unbelievably huge black hole close to Earth, sparking concerns about its potential danger. This new finding reveals the collision of 160 million suns in complete darkness, resulting in a pair of supermassive black holes. These monstrous black holes are set to merge at a record close distance of just 89 million light-years away. While this may still seem far, the prospect of faster-than-light spaceships in the future raises the need for a star guide map to avoid the hazardous objects in the universe. And at the top of this list are black holes.But what exactly is the danger posed by black holes? It's not just their ability to suck objects in; they can also roast them. Furthermore, where can we find the most dangerous gravitational monsters in the universe?Recent astronomical observations have led to the discovery of a binary star in the Telescopium constellation, accompanied by a third invisible object. This object turns out to be a black hole with five times the mass of the sun, yet with an astonishing density that shrinks its size to a mere 30 kilometers in diameter. Although it may seem unlikely for a spaceship to fall into such a small black hole, the fact that it resides just 1,000 light-years away from Earth has raised concerns among scientists.Moving a bit farther from our planet, about 1.5 thousand light-years, we encounter another peculiar black hole in the Monoceros constellation. This black hole, only 10 kilometers in diameter, exerts such immense gravitational force that it distorts the neighboring red giant star, resembling a squashed toy. Surprisingly, this black hole weighs 2.6 times more than the star itself. The potential danger lies in the possibility of our spacecraft being overloaded when flying past this star if we are not aware of the presence of this tiny, yet powerful, black hole.These discoveries shed light on the black holes that reside in close proximity to Earth. While we are currently safe from their grasp, it is crucial to continue exploring and understanding the mysteries of our universe to ensure our future space explorations are free from any unexpected encounters with these mesmerizing, yet potentially dangerous, celestial objects.
  • Subtitles section
  • 160 million suns are colliding with one another in complete darkness.
  • It sounds unbelievable, but there's no other way of describing this pair of supermassive black holes that astronomers discovered in December 2021.
  • The fusion of these two monsters will take place at a record close distance from Earth, just 89 million light-years away.
  • Okay, it's not that close, but one day we'll definitely invent faster-than-light spaceships, and then we'll undoubtedly need a star guide map to avoid the most dangerous objects in the universe.
  • Black holes.
  • Which ones lie in wait for us right around the corner in near-space?
  • Why can a black hole not only suck you up, but also roast you?
  • And where's the lair of the most dangerous gravitational monsters in the universe?
  • What black holes can we encounter right next door?
  • Astronomers recently discovered a binary star in the Telescopium constellation, and it comes with a bonus gift, a third invisible object.
  • That's a black hole five times heavier than the sun, but its unbelievable density makes it just 30 kilometers in diameter.
  • It's not that easy to make your ship fall into this black hole, even if you wanted to.
  • However, scientists are still worried, because it literally wanders around in our backyard, just 1,000 light-years away from Earth.
  • So let's map this black hole next door, even though it's tiny.
  • A bit farther, 1.5 thousand light-years away from our planet, there's another unusual black hole in the Monoceros constellation.
  • Just 10 kilometers in diameter, this tiny object stretches and squashes the neighboring red giant like a soft toy.
  • This black hole is 2.6 times heavier than the star.
  • If we didn't spot this tiny monster, our spacecraft could be overloaded when flying past the red giant.
  • In the interstellar outskirts of our Milky Way, there are dozens of known objects similar to black holes.
  • At the same time, astronomers believe that in our galaxy, there are at least 10 million black holes formed from massive stars.
  • It's challenging to find and map such small objects, but they don't pose any serious threat to space travel anyway.
  • Whereas supermassive black holes are another story.
  • Which of the world's most famous space monsters is the largest?
  • Our nearest supermassive black hole is located in the Sagittarius constellation, 26,000 light-years away from Earth.
  • The object, called Sagittarius A-star, weighs more than 4 million suns and is 44 million kilometers in diameter.
  • Only three such galactic monsters would fit between Earth and the Sun, but that's nothing compared to giants from distant galaxies.
  • An absolute monster lurks in the Coma Berenices constellation, 300 million light-years away.
  • This black hole in the center of a giant elliptical galaxy has a mass similar to 21 billion suns, and the size of its event horizon, that is, the region of space where the gravitational pull is so strong that even light cannot escape,
  • Is 70 billion kilometers.
  • There would be more than enough space for three of our solar systems to Pluto's orbit within such a diameter.
  • Just one slight navigational error on our way to this distant galaxy and our spaceship is destroyed.
  • But an absolute record among the black holes known to science is held by TON 618 in the Canis Venatici constellation that lies at a distance of more than 10 billion light-years.
  • This object strongly absorbs interstellar gas and has a mass of 66 billion suns and a diameter of 242 billion kilometers.
  • So much room is enough to fit 11 solar systems in a row.
  • And even more so, a gluttonous TON 618 could be more enormous nowadays, since on Earth we see it the way it used to be 10 billion years ago.
  • But it's not just supermassive black holes themselves that are a threat.
  • What are the dangers of the effects they produce?
  • For example, TON 618 has a huge creation disk.
  • Basically, it's a very fast whirlpool of matter that's heated to millions of degrees and heading towards the mouth of the black hole.
  • If our spaceship gets there, it will evaporate in the blink of an eye.
  • So a danger zone radius around TON 618 is a whole light-year.
  • If you look at the famous photo of the black hole captured in the core of the Messier 87 galaxy, you'll see precisely this huge accretion disk.
  • Moreover, this monster that lies 53 million light-years away from Earth, disgorges a gigantic plasma jet that spreads as far as 5,000 light-years.
  • Right after our faster-than-light ship hits this black hole's burp, the crew will be exposed to a lethal dose of radiation.
  • But there's a thousands of times more dangerous zone in the Hercules constellation.
  • Here, 2 billion light-years away from Earth, a supermassive black hole emits two fountains of charged particles.
  • Their total length is around 1.5 million light-years.
  • The distance between these radio jets could be enough to fit 10 Milky Way galaxies.
  • If a faster-than-light ship gets here, all its systems will fail.
  • So far, scientists have no idea how exactly the black hole managed to create an effect like that.
  • And it's the unknown that frightens them the most.
  • What black holes had scientists baffled and therefore are particularly dangerous?
  • In the Sexton's constellation, located 13 billion light-years away from Earth, a black hole weighing like 1 billion suns wove a real web of galaxies.
  • The scariest part is that this space spider somehow managed to reach such an immense mass in less than a billion years after the birth of the universe.
  • The models showing how black holes originate prove it's just impossible.
  • So we'd better stay out of that region for now.
  • As well as into the center of the galaxy located in the Ursa Major constellation that's almost 10 billion light-years away from us, the black hole that lies there fails to carry out its primary responsibility.
  • It's surrounded by matter, but doesn't absorb it for some inexplicable reason.
  • It's as if some unknown force turned the black hole off so that gas around it cooled down and started to produce new stars.
  • That's what we can see now, and probably the best choice here is not to poke the sleeping beast.
  • However, the biggest mystery that science can't explain is the galaxy in the Hercules constellation more than 2.5 billion light-years away.
  • Judging by the evidence of radio emissions, there used to be a black hole that could possibly be even more massive than TON 618.
  • However, it's not there anymore.
  • Of course, black holes can evaporate, but it's a prolonged process that takes trillions of years.
  • So, what happened to this space monster is just beyond our understanding.
  • The only thing to calm us down is that all these black holes are very far from us.
  • Or not.
  • One theory about mysterious dark matter, the one that makes up most of the mass of the universe, states that black holes are literally everywhere.
  • They're just very small.
  • One day they got stuck in microscopic size, and now they can neither grow nor evaporate.
  • According to this theory, every big city on Earth has at least one micro black hole.
  • Write in the comments in which borough or building of your city such monsters might be hiding.
  • Could it possibly be them going door to door and stealing socks out of our washing machines?
  • Hmm, something to think about.
