15 Black Hole Facts That SCARE Astronomers | Space Discoveries 2020

 black holes are among the most  intriguing astronomical objects in the  world  yet there's so many things we don't know  about them  number 15 black holes don't actually  suck  matter did you know that black holes  don't actually suck anything around them  most people think that black holes are  endless cosmic vacuums that eat up  everything unfortunate to go in contact  with him  if you replace the sun with a black hole  of equal mass  earth would not get sucked in it would  continue orbiting the black hole as it  orbits the sun today  black holes look like they're sucking in  matter from all around but that's a  common misconception  companion stars shed some of their mass  in the form of stellar wind  and the material in that wind then falls  into the grip of its hungry neighbor  a black hole 14. did you know that every  black hole contains a universe  that's one of the most insane things  people don't know about black holes  the idea that our universe is entirely  contained within a black hole provides  answers to these problems and many more  it eliminates the notion of physically  impossible singularities in our universe  and it draws upon two central theories  in physics  the notion of black holes as wormholes  could explain certain mysteries in  modern cosmology  for example the big bang theory says the  universe started as a singularity  but scientists have no satisfying  explanation for how  such a singularity might have formed in  the first place  number 13 black holes turn into  spaghetti  black holes turn everything they come in  contact with into spaghettification  yep that's actually a scientific term  because you'll turn  into a noodle as you spin at first  you're not going to notice much of  anything  but the black hole's gravity is getting  stronger and stronger  and eventually you pass a point of no  return  now you can't get out and gravity from  the black hole is starting to pull on  your feet  more than your head number 12  they are the deadliest force in the  universe considering that the universe  is filled with comets  supernovas asteroids neutron stars and  many other deadly phenomena that's sane  a lot  there are two broad categories of black  holes one of them is a monstrous black  hole that we find in the centers of  galaxies  those could be up to a million times the  mass of the sun  and we don't completely understand how  they form but all of the best data tells  us that we've got one at the middle of  every galaxy  then there's a much smaller kind and in  some ways a much more dangerous kind  that is the end product of the life of a  star and those could be in your way as  you journey across the galaxy  black holes are able to swallow  universes whole of course if we come in  contact with a black hole  none of our current tools or weapons are  able to fight off against it  its deadly forces would rip our solar  system to shreds  number 11 black holes delete your past  did you know that black holes  technically delete your past two  in our world our past is what determines  your future  if a physicist knows how the universe  starts out she can calculate its future  for all time in all space  however a uc berkeley mathematician begs  to differ from this  she found that some black holes actually  break down this rule  if someone were to venture into one of  these relatively benign black holes they  could survive  but their past would be obliterated and  they could have an infinite number of  possible futures  because it should be possible to survive  the transition from our world into a  black hole world  physicists and mathematicians have long  wondered what that world would look like  and have turned to einstein's equation  of general relativity  to predict the world inside a black hole  these equations  work well until the observer reaches the  center or singularity  where in theoretical calculations the  curvature of space-time becomes  infinite number 10 the biggest black  hole  ever found the largest black hole ever  found is big  even by astronomical standards and  that's sane a lot  known as j2157 the enormous black hole  weighs in at 34 billion  times the mass of the sun and is  consuming the mass of a normal star  on a daily basis this black hole was  discovered in 2018  the observations indicate it dates back  to about 1.2 billion years after the big  bang and is the most  massive yet weighed from this era of  cosmic evaluation  number nine even the smallest black  holes are deadly  igr17091-3624  is one of the tiniest black holes that  rotates around the universe  and its wind strength outstrips the  bigger black holes by a magnitude of 10  times the maximum measured distance  right here in our milky way  is this small stellar mass and here's  what you don't learn from the black hole  every day  it actually has a heartbeat thanks to  its pulse which is what we know that  keeps it intact  number eight black holes can even burn  brighter than the sun  did you know that a supermassive black  hole burns 429  trillion times brighter than the sun  this discovery is remarkable and  fascinating since black holes are always  synonymous with darkness  but some are very luminous indeed this  recently found black hole reflects the  brightest massive quasar ever seen  any light that bright is expected to  pose threatening threats to both human  and other life number seven  a black hole could fry earth precisely  due to that it shouldn't be surprising  to know that a black hole is completely  capable of destroying earth with its  heat and not even with its immense  gravity at the speed of light  should earth somehow get sucked into a  black hole we might not even notice it  for the first  few moments the effect would be  incredibly subtle  similar to a change in tides a shift in  the stars and then a deadly rain of  light that would fry us up due to the  radiation  exceeding the speed of light number six  how black holes are created so how  exactly is a black hole made  well supermassive black holes are  thought to have developed during the  primitive moments of creation  due to their immense age some of these  are among the oldest objects in the  universe  black holes of stellar mass are expected  to form when very massive stars collapse  at the end of their life cycle  after a black hole is formed it can  continue to grow by absorbing mass from  its surroundings  this collapse also causes a supernova or  an exploding star  that blasts part of the star into space  scientists think supermassive black  holes formed at the same time as the  galaxy they're in  number five black holes can swallow each  other  we know black holes are capable of  swallowing any other type of matter that  come in contact with them  but did you know that black holes can  even swallow other black holes too  this is an effect known as merging  galaxies and incredibly enough  the black hole observed doing this was  the largest in the spiral galaxy  observed  called ngc 3393  number four black holes also eject  matter  black holes are ironically also capable  of ejecting incredible amounts of matter  and energy by themselves  for example h1743-322  hurls cosmic bullets into space at the  speed of light  causing a rain of destroyed debris space  dust and matter being ejected across the  width of space  causing possible collisions and even  destruction after it happens  number three black holes can distort  space  itself black holes can even distort  space itself  and everything surrounding them for  billions of light years  putting dents in the space-time  continuum they've even been suspected of  causing miniature universes to both  fold and collapse due to their  incredible space and time distortion  that's why black holes are so darn  powerful and  mystifying number two black holes can  move and even go  rogue if there's anything scarier than a  standard cookie cutter black hole  it's a rogue black hole these are  threats to civilization due to their  unpredictability  black holes were thought to be  stationary prior to their discovery  turns out they aren't and some are able  to travel space at blazing speeds such  as 3c186 which traveled 5  million miles per hour on its own  and number one we could be living inside  a black hole not only is a black hole in  the center of our galaxy  there's even a chance we could be living  in one ourselves in a black hole  singularity and we don't even know it  yet  based on what we know about the  universe's rapid expansion the universe  shrinks down to a singularity a  cosmological model known as the big bang  theory  so what are your thoughts on black holes  let us know in the comments below    you
