How Strong Would Be a Black Hole the Size of a Coin

black holes the most terrifying mysterious and fascinating objects in the universe it eternally hungry they eat everything in their path and are constantly expanding but how small and how big can a black hole be let's find out it's not very easy for a black hole to be born most often they're just a result of a massive star ending its life cycle if you take a star and squeeze it very very hard at some point it cannot withstand the pressure anymore so it collapses and turns into a black hole for example we can create a black hole by shrinking the sun to about 1.8 miles or squeezing the earth into the size of a pea either way in the end we get a mysterious dark object with Incredible mass and gravity unlike stars and planets black holes have no size restrictions they grow when they eat the matter around them but how much does their size vary for example can they be very small theoretically yes there may be black holes with a diameter of one atom or even less they're called primordial black holes they may or may not exist and if they do they're probably the oldest objects in the universe older than the atoms themselves they would have formed right after the big bang a long time ago when the universe still had an incredible density a huge amount of energy and in general was like a boiling broth any particle that was slightly denser than its neighbors could form a black hole and the smallest of them would still weigh trillions of pounds those that were the size of atoms would weigh as much as a big mountain and those that would weigh as much as the Earth could be a little bigger than a coin but even if they exist they're pretty harmless the temperature in them would be so many times hotter than in our sun so they would evaporate pretty quickly after their birth now let's check out the black holes we know and saw the first ones are called Stellar black holes usually they weigh tens of solar masses which doesn't seem like much until you remember that the sun weighs 9 millions of pounds don't even try to imagine this number it has 30 zeros the smallest black hole known to us is about two to four times heavier than the sun it's a lonely hole that wanders through space in search of prey the one that's closest to us is called Gaia bh1 it weighs about 10 times more than the Sun and can reach many miles in size and the farthest one is called m33x7 it's somewhere around 3 million light years away from us and right now it's eating a blue giant that's several times bigger than our sun now let's move to the so-called intermediate Mass black holes you see just eating a few Stars isn't enough to become larger in size black holes must either absorb a lot of stars or more often merge with another black hole one of the first intermediate Mass black holes that we found was born this way it weighs 142 times more than the sun it's even larger than some counties on Earth recently we discovered two black holes in a Galaxy 17 billion light years away from us one day they'll merge but right now these guys are spinning around each other in a crazy dance and while doing that they release a crazy amount of energy it may seem scary but it's nothing compared to what comes next let's move to some serious stuff supermassive black holes giant inexplicable monsters that are millions of billions of times bigger and heavier than our sun but how do they become so huge the universe is about 14 billion years old the black holes grew very slowly so they couldn't have time to eat so much matter or merge with each other so quickly so maybe they were also born from the Stars but very very big ones quasi-stars to imagine their scale let's take for example the red supergiant Stevenson 218. compared to this star our sun is just a grain of sand even smaller and Stevenson 218 would be a grain of sand next to a quasi-star we don't know if they really existed though they could have formed after the birth of the universe they could be so big that their core collapsed under their own weight before they even formed and if that's the case a small black hole would have appeared in the center of this quasi-star now the frenzied gravity of the black hole held the star together and ate it at the same time the temperatures were huge so the star remained stable and they would live like this for millions of years until the black hole would grow to enormous sizes most supermassive black holes are located in the centers of galaxies you might think that our galaxies orbit around them as we do around the Sun and that one day we will inevitably all be dragged inside it but don't worry that's not the case although these guys are incredibly massive they're not very large in diameter they can't swallow entire Galaxies for example in the center of our Milky Way there's a black hole called Sagittarius A it has four million solar masses but it's still quite small in size only 17 times larger than the Sun and yes it's still considered small if we had replaced the sun with this black hole it wouldn't even have reached the orbit of Mercury Sagittarius A is actually pretty nice and calm yes it still swallows giant stars but it's definitely not a threat to us but not all of them are like that for example a black hole in the Galaxy BL lacerte devours a huge amount of gas and dust if we were somewhere near it it would look 115 times larger than the Sun and we would have burned up just getting close to it do you remember that first black hole we ever captured in a photograph it's located in the Messier 87 Galaxy and it may look small and cute in the photo but in reality it's capable of absorbing our entire solar system up to the Orion belt and even further well now that we've discussed the terrifying size of supermassive black holes it's time to move on to the real Titans of the universe Ultra massive black holes terrifying unimaginable giant the largest objects that have ever existed and probably will exist in our world their masses exceed the mass of the Sun by tens of billions of times their gravity becomes so strong that they create quasars around them discs that shine brighter than thousands of galaxies combined remember we talked about the fact that supermassive black holes aren't able to eat galaxies well these guys devour not only their host galaxies but literally everything on their path the ultra massive black hole at the center of the Galaxy OJ 287 has 18 billion solar masses it's so gigantic that it has another black hole orbiting it it would also easily fit not one but three solar systems inside of it and now finally we've come to the largest object in the entire universe t-o-n-618 the almighty destroyer of worlds a black hole that has eaten far more than one Galaxy its mass exceeds 66 billion solar masses and it could fit 11 solar systems inside of it the Quasar around to n618 shines brighter than 100 trillion Stars its light is so powerful that it has even reached us even though we're at a distance of 18 billion light years from it and the creepiest part is this isn't even its true size this is what it looked like around 10 billion years ago since ton 618 is so far away its Light reaches us for a very long time that means what we see is how this black hole looked after the universe was born but what does it look like now we have no idea but it's probably millions billions of times bigger that's it for today so hey if you pacified your curiosity then give the video a like and share it with your friends or if you want more just click on these videos and stay on the bright side
