What Are The Black Holes?

 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.

Interesting Facts About Jupiter Probably you didn't know

Interesting Facts About Jupiter  Probably you didn't know  Jupiter was appropriately named after the king of the gods. It’s massive, has a powerful magnetic field, and more moons that any planet in the Solar System. Though it has been known to astronomers since ancient times, the invention of the telescope and the advent of modern astronomy has taught us so much about this gas giant. 1. Jupiter Is Massive: It’s no secret that Jupiter is the largest planet in the Solar System. But this description really doesn’t do it justice. For one, the mass of Jupiter is 318 times as massive as the Earth. In fact, Jupiter is 2.5 times more massive than all of the other planets in the Solar System combined. But here’s the really interesting thing… If Jupiter got any more massive, it would actually get smaller. Additional mass would actually make the planet more dense, which would cause it to start pulling it in on itself. Astronomers estimate that Jupiter could end up with 4 times its curren...

surprising facts about Bill Gates

surprising facts about Bill Gates Most people know three things about Bill Gates: He is one of the richest men in the world. He cofounded one of the most successful tech companies of all time in Microsoft. He's an extremely generous philanthropist through the Bill & Melinda Gates Foundation. But despite his philanthropic efforts and  online presence , there are a lot of things about Gates that many are unaware of. Here are 17 facts you probably didn't know about Bill Gates: 1. As a teen at Lakeside Prep School, Gates wrote his first computer program on a General Electric computer. It was a version of tic-tac-toe where you could play against the machine. 2. Once his school discovered Gates' coding abilities, they let him write the school's computer program for scheduling students in classes. Gates slyly altered the code so he was placed in classes with a "disproportionate number of interesting girls." 3. Gates also read the entire "World Book Encyclope...

What is the Bermuda Triangle?

What is the Bermuda Triangle? For decades, the Atlantic Ocean’s fabled Bermuda Triangle has captured the human imagination with unexplained disappearances of ships, planes, and people. Some speculate that unknown and mysterious forces account for the unexplained disappearances, such as extraterrestrials capturing humans for study; the influence of the lost continent of Atlantis; vortices that suck objects into other dimensions; and other whimsical ideas.  Some explanations are more grounded in science, if not in evidence.  These include oceanic flatulence (methane gas erupting from ocean sediments) and disruptions in geomagnetic lines of flux. Environmental considerations could explain many, if not most, of the disappearances.  The majority of Atlantic tropical storms and hurricanes pass through the Bermuda Triangle, and in the days prior to improved weather forecasting, these dangerous storms claimed many ships.  Also, the Gulf Stream can cause rapid,...
