Source Title: What are Black Holes?
Website: https://www.sciencealert.com/black-holes
Website :Black holes are volumes of space where gravity is extreme enough to prevent the escape of even the fastest moving particles. Not even light can break free, hence the name ‘black’ hole. A German physicist and astronomer named Karl Schwarzschild proposed the modern version of a black hole in 1915 after coming up with an exact solution to Einstein’s approximations of general relativity.
Schwarzschild realised it was possible for mass to be squeezed into an infinitely small point. This would make spacetime around it bend so that nothing – not even massless photons of light – could escape its curvature.
The cusp of the black hole’s slide into oblivion is today referred to as its event horizon, and the distance between this boundary and the infinitely dense core – or singularity – is named after Schwarzschild.
Theoretically, all masses have a Schwarzschild radius that can be calculated. If the Sun’s mass was squeezed into an infinitely small point, it would form a black hole with a radius of just under 3 kilometers (about 2 miles).
Similarly, Earth’s mass would have a Schwarzschild radius of just a few millimeters, making a black hole no bigger than a marble.
For decades, black holes were exotic peculiarities of general relativity. Physicists have became increasingly confident in their existence as other extreme astronomical objects, such as neutron stars, were discovered. Today it’s believed most galaxies have monstrous black holes at their core.
In My word : Even fastest matter can’t get out from black hole because of the gravity of black hole. Not even a light can go threw black hole. That’s the reason why black hole is named black hole. Karl Schwarzschild is a German space scientist who pulled up Einstein’s approximations. He gave a exact solution of Einstein’s approximation and he recommended a modern version of black hole. Schwarzschild knew that mass can be small sized in to tiny little point, because of these reasons space times getting crushed and bend so not even a small fast light can escape this curvature. The distance between boundary and infinitely dense core is called Schwarzchild. In theory we can measure all the radius. If the sun is small sized in to small dot like as other black hole it can make a 3km 2mile black hole. If earth mass is small sized it will make a black hole smaller than a single rock.

Website: How are black holes made?
Scientists think that black holes are created in places where matter gets extremely dense (where a huge amount of material is crammed into an extremely small space). This can happen in the centers of large galaxies or when a giant star collapses and shrinks during the final phases of its life. When matter gets so dense that light cannot escape from it, the region that it is in becomes a black hole.
website: How Do Black Holes Form?
Scientists think the smallest black holes formed when the universe began.
Stellar black holes are made when the center of a very big star falls in upon itself, or collapses. When this happens, it causes a supernova. A supernova is an exploding star that blasts part of the star into space.
Scientists think supermassive black holes were made at the same time as the galaxy they are in
In My word : If a star that has 3 times mass bigger than a sun collaspe and with no fuel any more there can be a black hole in universe. there will be a gravitational shock. Star is getting small sized however the mass is same but the size is getting smaller so its pulling eveything in side. star is getting huger and huger and in finall steps its having a super nova and it expoleds by it self. so the stars getting bigger and bigger it exploeds it still has the smae mass but its getting shrinked so its pulling everything in even a light

Website : Small black holes populate the universe, but their cousins, supermassive black holes, dominate. These enormous black holes are millions or even billions of times as massive as the sun, but are about the same size in diameter. Such black holes are thought to lie at the center of pretty much every galaxy, including the Milky Way. Scientists aren’t certain how such large black holes spawn. Once these giants have formed, they gather mass from the dust and gas around them, material that is plentiful in the center of galaxies, allowing them to grow to even more enormous sizes. Supermassive black holes may be the result of hundreds or thousands of tiny black holes that merge together. Large gas clouds could also be responsible, collapsing together and rapidly accreting mass. A third option is the collapse of a stellar cluster, a group of stars all falling together. Fourth, supermassive black holes could arise from large clusters of dark matter. This is a substance that we can observe through its gravitational effect on other objects; however, we don’t know what dark matter is composed of because it does not emit light and cannot be directly observed.
In my word : There are many small black holes in the universe however there are also massive black holes too. These huge massive black holes are much bigger than a sun but there diameter is almost same as a Sun. These huge massive black holes locations are hypothesized. Most scientist hypothesized that this massive black holes are located in the middle of galaxy. Scientist aren’t really sure how this huge black holes are made however many of scientist made hypothis about this massive black holes. 1. Massive black holes are getting lot of gases and dusts from the middle of the galaxy.2 Massive black holes could be made by lot of small black holes. 3 swarm of stars fell in to a huge black hole 4 super massive blackholes can be made by dark matter. We can find this dark matter by gravitational effect on other object however we don’t have any information about this dark matter because this dark matter doesn’t let scientist to observe and it doesn’t let light out so scientist couldn’t really know what it is made of
