 What Are The Black Holes?

Black holes are among the strangest and most attractive in outer space. It is so dense, with so many strong structures that no light can tell if it gets close enough.

Albert Einstein first predicted the Black Forest in 1916, with his theory of relativity. American astronomer John Wheeler coined the term "not found" several years after 1967. After decades of knowing black holes only by theoretical devices, the first black holes were discovered in 1971.

Then, in 2019, the first recorded image of a black hole was released in association with the Event Horizon Telescope (EHT). The EHT site detected a black hole in the middle of Galaxy M87 while the telescope surveyed the event horizon, or the past of an area where no one could escape from the black hole. The image shows a map of the sudden loss of photons (particles of light). It also opened up a whole new field of research into black holes, and now astronomers know what a black hole looks like.

So far, astronomers have identified three types of black holes: stellar black holes, supermassive black holes, and intermediate black holes

Great Black Holes - The Birth of Giants.

Tiny black holes fill the universe, but their cousins, the supermassive black holes, dominate. These giant black holes are millions or billions of times larger than the Sun, but they are about the same size. Such a black hole is thought to be at the center of almost every galaxy, including the Milky Way.

Scientists are not sure how large black holes form. Once these giants are ready, they accumulate massive amounts of dust and gas around them, where they are found in abundance in the center of galaxies, causing them to grow in maximum size.

Supermassive black holes can be the result of hundreds or thousands of small black holes merging. Large clouds of gas can also be responsible, falling together and acting rapidly on a large scale. A third option is to remove a group of stars, all falling together. Fourth, large clumps of dark matter can cause supermassive black holes. It is a substance that we can observe through its gravitational effect on other objects. However, we do not know what is in dark matter because it does not emit light and cannot be observed directly.

What do black holes look like? 

black holes are as black as the blackness of space. ... But around a black hole, there is light from a luminous swirl of superheated matter yet to fall into the black hole. When the light passes near the event horizon, it bends and gets distorted by the pull of the black hole's strong gravity.
