SPACE

Black holes are the points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity.At the center of our galaxy, a super massive black hole churns. Because black holes swallow all light, astronomers can't spot them directly like they do the many glittery cosmic objects in the sky. But there are a few keys that reveal a black hole's presence. Black holes are also messy eaters, which often betrays their locations. Scientists think that ever since the universe began it is when the black hole also began.

Black holes are the strangest objects in the Universe. They are unique in it’s own way. A black hole does not have a surface. Instead it is a region of space where matter has collapsed in on itself. This collapse makes a lot of mass being concentrated in an incredibly small place. The gravitational pull of this region is so great that nothing can escape not even light. Wow that means that if a spacecraft goes in then the people inside can dye. That is incredibly dangerous.

A black hole is anything but empty space. A black hole is ten times more massive than the sun. It has the diameter of New 

York. The gravitational force is so strong even light cannot escape a black hole. Also it is the most fascinating object in space.

 A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.

Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars. Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or "stuff," in an object.

Another kind of black hole is called "stellar." Its mass can be up to 20 times more than the mass of the sun. There may be many, many stellar mass black holes in Earth's galaxy. Earth's galaxy is called the Milky Way.

The largest black holes are called "supermassive." These black holes have masses that are more than 1 million suns together. Scientists have found proof that every large galaxy contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy is called Sagittarius A. It has a mass equal to about 4 million suns and would fit inside a very large ball that could hold a few million Earths. 

A black holes is a mysterious holes in the universe.  People say that when you go through it, you never come back. As the people of NASA say “A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.” (https://www.nasa.gov/audience/forstudents/k-4/stories/nasa-knows/what-is-a-black-hole-k4.html)  Black holes are like a door except no one ever went through it. As looking a picture from NASA, it shows that the black hole is pulling power from the neutron star. Black hole other links are listed below here (https://science.nasa.gov/astrophysics/focus-areas/black-holes , https://www.nationalgeographic.com/science/space/universe/black-holes/) The black hole still reamians a mystery to this day

      Space and the Black Hole 

    A black is a hole that has gravity that can pull everything to it.  Black holes is big or can be small.  Black holes create big gravity sinks.   Even light cannot escape the black hole.  Black holes can be created from a large star that dies from a supernova.  The biggest a black hole can be is 24 times more bigger than the sun.

  Black holes are like a place in space where it is able to suck up anything such as stars, satellites, and even planets.  So what if earth encountered a black hole. My hypothesis is that it will destroy earth by sucking it up. Well, it’s a good thing that they are really far, far, away from us. This is what I think about black holes.  

Hi and today i will talk about space because i am always curious of what is up their like human life and stuff. Space is completely silent because there is no life up their apparently. I don’t believe there is no life up there. I hope i go up their one day. At night i look at the stars because they are really pretty.

A black is a place where gravity pulls so much that light can not even get out at all because it is strong. You can’t even see the black hole at all since it is invisible and the black holes size can be small or big. Space tools help find black holes.There is another black hole called “stellar” and its mass is up 20 times more than the mass of the sun, many of them have a earth galaxy called the milky way. If a person goes in a black hole their body stretches and is torn apart.

 

A black hole forms when the of massive star collapses upon itself.I am going to tell you more about the black hole because it is interesting to me.The black hole is formed at the same time as the galaxy they are in and that is what scientists think.I have my own thought that it is just a empty galaxy. I hope you learn more about it.

Let’s see if you can destroy a black hole? The answer is no because it is too powerful, it pulls gravity so much. Let’s just say you try to destroy a black hole with energy and it does not work because that energy is not strong enough. A milky way and black hole, The black hole is more powerful. If the milky way tries to destroy black hole it can’t because both of them cannot destroy them. 

It is called a black hole is because it sucks up all the lights that hits its border and reflects nothing.I hope you learned a lot but there is a few more things i need to tell you. The black hole has a surface known as the event horizon. There are several that think they are massive and scientists don’t believe that, our galaxy is filled with so many black holes is what i read. Black holes radiation will make it lose mass.

In conclusion, i have told you everything i know about the black hole and i wish i can see one. The black hole is dangerous because sometimes you can’t escape since you don’t have that many seconds left. Well that is all i can tell you for now. If you ever go to space be careful, i do want to go to space. Enjoy my facts. 

 Black holes is an empty space.  It is a great amount of matter compacted into a single small area. The size of black hole are ten times as massive as the Sun squeezed into a sphere, approximately the diameter of New York City.  The gravitational force is go great that even light can’t escape it once sucked in. There are many predictions on how they were made.  One of the  reasons for how they were created is that once a star dies it leaves behind a small, dense remnant core and if the core’s mass is three times greater than the Sun.  The force of gravity overwhelms and creates a black hole.  But usually they form from remnants of large stars that died in a supernova explosion.

      A black hole is just empty space and also a region of space having a gravitational field so much that no matter or radiation can escape. Black holes can be any size big or small. Black holes are the strangest and interesting thing in outer space.A black hole is a place in space where gravity pulls anything even light can not get out. Black hole can be cause when stars die.

          

SOURCES

A Black hole is  formed by the collapse of individual stars that are small, but extremely dense. Black holes consume the dust and gas from the galaxy around them, growing in size. Anything that goes to close to a black hole will disappear. There are 4 different types of black holes which is stellar, intermediate,supermassive, and miniature.

 What are black holes? Black holes are points in space that are so dense they create deep gravity sinks. Whatever is near the black hole will be sucked in and stretched like putty. Their force is so strong that if a star comes near the black hole it would be completely torn apart. 

  There are four different types of black holes. They are called the stellar, intermediate, supermassive, and miniature. The most common black hole is the stellar. The stellar As stars reach the ends of their lives, most will inflate, lose mass, and then cool to form white dwarfs. Black holes form when stars reach the ends of their lives, most will inflate, lose mass, and then cool to form white dwarfs. Since no light can get out of the black hole they are invisible. That means people can’t see black holes. However space telescopes can help people see the black holes in space. 

  How big are black holes? Black hoes can be big or small they all come in different sizes. The largest black holes are called supermassive. They have masses more than 1 million suns together. Scientists have found that black holes contains a supermassive hole in the center.

 How do they form? According to the text on this site it says “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.”

Black holes are enormous objects found in outer space. They have incredible gravitational attraction that is impossible to escape from if you get near enough. There are many black holes all over space, but they vary in size, which depends on their mass, or the amount of material they have inside them. Smaller, to average size black holes are called stellar black holes, but the largest ones are what we know as supermassive black holes. Supermassive black holes can be millions to billions times larger than stellar ones. They are usually located in the center of large galaxies, including our own; The Milky Way. Although no one is entirely sure how these supermassive black holes formed, some astronomers guessed that it could be from the huge clouds of gas from galaxies’ early stages. Another prediction they have is that stellar black holes begin to consume tons of materials, getting larger, and eventually becoming the size of a supermassive black hole. Along with this, they also say that another possibility could be that 

many stellar black holes cluster in order to form one large supermassive black hole. On the other hand, stellar black holes were formed simply from the collapse of large stars.

A black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City. The result is a gravitational field so strong that nothing, not even light, can escape. In recent years, NASA instruments have painted a new picture of these strange objects that are, to many, the most fascinating objects in space.                

The idea of an object in space so massive and dense that light could not escape it has been around for centuries. Most famously, black holes were predicted by Einstein's theory of general relativity, which showed that when a massive star dies, it leaves behind a small, dense remnant core. If the core's mass is more than about three times the mass of the Sun, the equations showed, the force of gravity overwhelms all other forces and produces a black hole.         

Scientists can't directly observe black holes with telescopes that detect x-rays, light, or other forms of electromagnetic radiation. We can, however, infer the presence of black holes and study them by detecting their effect on other matter nearby. If a black hole passes through a cloud of interstellar matter, for example, it will draw matter inward in a process known as accretion.

Another prediction they have is that stellar black holes begin to consume tons of materials, getting larger, and eventually becoming the size of a supermassive black hole. Along with this, they also say that another possibility could be that many stellar black holes cluster in order to form one large supermassive black hole. On the other hand, stellar black holes were formed simply from the collapse of large stars.

A black holes can be created when a star is dying.  Black holes can be big or small.  The small black holes are small but have the mass as big as a mountain.  The gravity in a black hole is is so strong that even light cannot get through.  The matter in the black hole causes the strong gravity.  The matter is squeezed inside the black hole.  The scientists are studying black holes by using satellites and telescopes.

There are steller, supermassive, and intermediate black holes.  

When a star gets too close to a black hole, it rips it to shreds.  The star's matter bleeds to the black hole and becomes brighter and hotter, which can be seen through a x-ray.

Black holes usually last forever, since nothing can escape it.  But it will eventually evaporate as they slowly leak.  That means that a black hole’s lifespan is relying on it’s mass.  Basically, a smaller black hole will live a shorter life than one with greater mass.
