Black Hole

 

we all know nothing can escape it we get it already but is it possible for something to escape a black hole and if you fell into one what would really happen the answer is probably going to surprise you and it's not what you think also new research shows that what we thought was a black hole in the middle of the milky way galaxy might not even be a black hole at all so what is it a tesseract  full of bookshelves or maybe the home of cthulhu  or perhaps it's something far more.

Mysterious it's pretty safe to say that we have no idea what a black hole is what's going on inside or if it's something else completely it's not like we can directly image one but at least we can now get images of their huge shadows in space in 2019 astronomers grabbed the first ever image of a black hole and a new polarized image shows powerful magnetic fields wrapping around a huge black hole shadow this super massive black hole is some 55 million light years away from us and is bigger than the entire solar system we're going to use this massive black hole for a simulation that involves you and a friend but we'll get to that in a bit you know the whole thing about nothing being able to escape a black hole well is this really true when a black hole eats up a star or a bunch of gas they generate a powerful flow of high energy particles close to the event horizon the ring of fire called hawking radiation at the edge and if a black hole is really chewing on something like a massive star powerful x-ray jets shoot out and the black hole becomes a quasar the brightest objects in the universe who says light can't escape it well now we have another argument about nothing being able to escape a hungry black hole this is because astronomers captured a neutron star in an elliptical orbit around a black hole that survived being swallowed completely however the dead star didn't get away from the black hole unscathed astronomers captured images of massive x-ray flares being belched out by the black hole as it was eating the star's material the star is trapped on a nine-hour elliptical orbit around the black hole and at its closest orbit the black hole rips off more of the star's material and becomes bigger it will try hard to get away but there's no escape as the black hole will eat it more and more until there's nothing left so now we all understand how powerful a black hole can be even

swallowing each other now you might be wondering what the closest one to earth is and if we're in any danger of a black hole eating us sometime soon just recently scientists discovered one of the smallest black holes ever found and it just so happens it's also the closest to earth astronomers have named it the unicorn because so far it's the only one of its kind and it's in the constellation monasteries the unicorn it's about three times the mass of our sun which is tiny for a black hole and it's about 1500 light years from earth which means you don't need to worry it's not goanna come and swallow us up anytime soon that's because black holes don't usually move and sit in one place eating up everything that gets too close to them but that doesn't mean they can't move and here's a scary thought in 2021 researchers got a big surprise when they discovered a super massive black hole racing across the universe at 177 000 kilometres per hour the big mystery is that astronomers don't know why the black hole which is three million times heavier than our sun is speeding through the center of the galaxy about 230 million light years away now that sounds crazy and it sounds fast but in 2017 scientists clocked another super massive black hole hurtling through space at 7.2 million kilometres per hour an enormous force would have to be responsible to get these things moving through space that fast maybe what we are seeing is the result of two black holes colliding the massive collision sending the other flying wildly through space so now we've all learned what happens when something gets too close and is sucked into a black hole so what happens to a person and could you survive the trip  now we've all heard that if you somehow get sucked into a black hole you would be stretched out or spaghetti  maybe even crushed or well you get the idea now this might be true if the black hole was small enough but a black hole let's say 30 to 100 times more massive than the Sun that's where reality becomes really strange the moment you entered a black hole reality would split you in two or clone you in one of these realities you would be incinerated and in the other you would plunge into the black hole and fall through it without being harmed how is this possible you ask well a black hole is a place where the laws of physics break down Einstein said that gravity warps space itself causing it to curve and space-time can become so warped that it twists in on itself yes we know that's a lot for the mind to wrap around so it's time for thought experiment in the beginning we said we were going to run a simulation involving you and a friend let's say that you both signed up to go on an adventure to the nearest black hole one of you will go in and the other will be an observer you flipped the coin your friend is going to watch you in horror as you plunge toward the black hole while they remain floating away at a safe distance now this is where it gets weird as you accelerate towards the event horizon your friend sees you stretch and contort as if they were looking at you through a giant magnifying glass but as you get closer to the horizon you appear to move in slow motion and as you reach the horizon you remain there motionless stretched across the surface of the horizon and the heat begins to engulf you your friend sees you slowly obliterated by the stretching of space and the ring of fire called hawking radiation before you get a chance to cross over into the darkness of the black hole 

you are reduced to ash game over but don't plan your funeral just yet we need to view this scene from your point of view because something even stranger happens nothing that's right from your perspective you would sail straight into the ominous black hole without so much as a scratch no slow stretching and no scolding hawking radiation either the reason is that you are in a free-for-all and therefore you feel no gravity if the black hole was smaller you'd have a problem because the force of gravity would be stronger at your feet than your head and stretch you out like spaghetti but something way more massive than our sun the forces would be small enough you wouldn't notice them but the sad and lonely part about this adventure is  that you would live out the rest of your life pretty normally until you reached the singularity but what's wrong with your friend and why are they telling everyone that you've been barbecued to a crisp by radiation outside of the horizon while you're chilling inside the black hole actually you really were burned to a crisp at the horizon and you are inside the black hole at the same time this is because the laws of nature require that you remain outside the black hole as seen from your friend's perspective

and quantum physics demands that information can never be lost and all information that accounts for your existence has to remain on the outside of the horizon however the laws of physics also require that you sail through the horizon without being fired by hot particles otherwise you would be in violation of Einstein’s theory of general relativity now some of you are going to say no way and you have to admit it's a conclusion that seems nonsensical how can a black hole clone me you're asking physicists called this mind-bending conundrum that black hole information paradox but in reality there's no paradox because no one ever sees your clone your friend only sees one of you and you only see yourself neither one of you can compare notes and no one really knows what happens and it doesn't matter if we try to send someone or some spacecraft inside of a black hole to relay back some data once inside there will be no way for a signal to get out and you'd be lost forever but what an awesome trip it would be so what about the mystery of the black hole in the middle of the milky way galaxy for years it was widely accepted that Sagittarius a is a black hole in the middle of the milky way galaxy however some astrophysicists from Italy now say the object which is as big as four million suns might not be a black hole after all the reason is that a huge gas cloud came close to the black hole the gravitational forces of Sagittarius a should have eaten the cloud but the cloud of Cass survived with an issue could it be the home of cthulhu well while we love to joke about this the answer might just be as mysterious some scientists say that the center could be a big bundle of that incredibly elusive stuff they call dark matter which is invisible and thought to account for 80 percent of the total matter in the universe but cannot be detected because it doesn't interact with light now scientists have proposed that black holes themselves could be formed out of dark matter which would explain why they conform so quickly before the galaxies around them and one day that might be proven to be true we're starting to find out more every day and tomorrow we might find out everything we thought we knew is wrong so make sure you stay tuned here so we can discover the universe together
