Have you ever wondered what a Black Hole is, or what happens if you go into one??? Well now’s your chance to find out about them.There are many theories to Black Holes and if they are real or not. But Black Holes are real. Karl Schwarzschild is the founder and the theory master to Black Holes.
Black Holes are mostly found inside of the Milky Way. There are many types of galaxies and many different types of Black Holes. A normal galaxy has gases and stars
Black Holes are referred to stars, and nothing from light or any kind of matter is able to escape the gravitational pull of that Black Hole. Black Holes are the last of the line after Neutron Stars and White Dwarfs. Black Holes are about 10-15 more times/massive than the own Sun itself. When the Black Hole reaches its final "stage" they blow up into also known as a supernova. Most of the debris is left behind as well which fusion can no longer take place. The Black Hole will collapse or close on itself if no force is to the opposing gravity. Nuclear fusion creates some energy and some pressure with the Gravity of the Black Hole. So with no force, the Black Hole shrinks to zero volume. Black Holes pull in all kinds of matter. Black Holes are small, but you wouldn't think they would be. They may be small but they have the energy to suck things up into themselves. A usual diameter of a regular black hole is 4 times the diameter of the sun. With the cause of them being small, distant, and dark, they wouldn't be able to be seen or observed. Now if you get too close to one, you may die. So black holes are still a mystery to be solved. Black Holes are massive in weight and they get bigger the more matter they suck up/ absorb. Black Holes are like the sibling(s) to wormholes. Blac...

... hole. The opening of a black hole is called the event horizon. And once something goes inside, it is trapped forever inside of it. Light, matter and other things cannot escape. The radius of each event horizon is called the Schwarzschild radius, named after Karl Schwarzschild the person who led to the theory of black holes A black hole is when there is a strong gravitational pull and there was a time delayed. The whole light not being able to escape thing seems pretty complicated. why? Because when you think about it, light not being able to escape the black hole doesn't seem too realistic. Black holes are created from an overdensity of a star collapsing in on itself. That overdensity is what creates the whole black hole part, the concept of the black hole sucking things in and possibly destroying them without a trace, that is the part that makes it seem weird.
Starting with black holes, Khalili describes the creation of one. I found that a black hole is what remains when a massive star dies. Because stars are so massive and made out of gas, there is an intense gravitational field that is always trying to collapse the star. As the star dies, the nuclear fusion reactions stop because the fuel for these reactions gets burned up. At the same time, the star's gravity pulls material inward and compresses the core. As the core compresses, it heats up and eventually creates a supernova explosion in which the material and radiation blasts out into space. What remains is the highly compressed and extremely massive core. The core's gravity is so strong that even light cannot escape. This object is now a black hole and literally cannot be seen because of the absence of light. Because the core's gravity is so strong, the core sinks through the fabric of space-time, creating a hole in space-time. The core becomes the central part of the black hole called the singularity. The opening of the hole is called the event horizon. Khalili describes that there are two different kinds of black holes:
The origins of the super-massive black holes which concludes how they were formed and what caused them to form is an unsolved problem which is yet a mystery of astrophysics. ( Millis 2014)
...f gas, which collapsed and broke up into individual stars. The stars are packed together most tightly in the center, or nucleus. Scientists believe it is possible that at the very center there was too much matter to form an ordinary star, or that the stars which did form were so close to each other that they coalesced to form a black hole. It is argued that really massive black holes, equivalent to a hundred million stars like the Sun, could exist at the center of some galaxies
A Black Hole is defined as an object in space that is so compact, that has a gravitational pull so powerful, not even light can escape its pull. In most cases Black Holes are formed when a massive star (much larger than our own) undergoes a supernova explosion. When this happens, the star may collapse on its own gravitational pull, thus resulting in a an object with infinitely large density and zero volume. As a result, the escape velocity (the speed required to escape the gravitational pull) becomes even greater than the speed of light, and because nothing can travel faster than the speed of light, nothing can escape a black hole.
Karl Schwarzschild is credited with being the brilliant astronomer who developed the concept of black holes. In 1916, using Einstein's general theory of relativity, he began to make calculations about the gravity fields of stars. He concluded that if a huge mass, such as a star, were to be concentrated down to the size of an infintessimal point, the effects of Einstein's relativity would get really fairly extreme. Schwarzschild doubted that a star could get that small, and theorized that if a star did infact shrink upon itself like that, its gravity would remain the same and the planets revolving around it would remain in the same orbits they always had. Since then however, some of Schwarzschild's theories have been disproved, but most of his initial theories hold intact today. The Schwarzschild Radius, the maximum radius a body with a specific mass can have that won't let light escape, is named in his honor, and the equation of which is still in use today: Rs=2MG/(c^2)
Have you ever watched a sci-fi movie and wondered if some of the subjects on futuristic transport occurring in space could be a possibility? For many years scientists have been discovering new phenomenons in space. In 1916, the first black hole was discovered by Karl Schwarzschild, which wasn't proven until the late 1950’s. A wormhole is a hypothetical connection that you can travel through to get from point A to point B almost instantaneously. Have you ever wondered what might lie on the other side of a black hole? Some scientists have been studying the “holes of space” and have found very surprising results: The black hole, the white hole, and the wormhole. In this paper we will explore wormholes and discuss how black holes and white holes relate.
Although Dr. Hawking impacts many areas of science and cosmology, his work with black holes has revolutionized modern physics. He works in all areas of black holes, including how they work, singularities, and most importantly, Hawking radiation. Black holes are very simpl...
We can also prove that dark matter exists in galaxies by examining how they spin. When an object rotates in a circular orbit, the object has a tendency to fly off in a path tangent to the orbit. If the stays within the orbit, it has a radial acceleration which is equal to its velocity squared over the radius of the orbit. The only force which is keeping the body in the orbit is the force of gravity, which is dependent on the mass of the system. Knowing this, physicists can calculate the mass of a galaxy by looking at how fast stars orbiting its center are moving. Physicists can also calculate where the highest percentage of dark matter should be in the galaxy. In most cases, it is located in a ring just outside the galaxy. In the case of the galaxy shown in the photo, dark matter must be present in the dark space between the nucleus of older yellow stars and the outer ring of young, blue stars.
Before I begin to speak about black holes, I will have to explain what the white glowing specks in the sky are. Without a star a black hole could not be formed. In the beginning of a star life a hydrogen is a major part of its development. Stars form from the condensation of clouds of gas that contain hydrogen. Then atoms of the cloud are pulled together by gravity. The energy produced from the cloud is so great when it first collides, that a nuclear reaction occurs. The gasses within the star starts to burn continuously. The hydrogen gas is usually the first type of gas consumed in a star and then other gas elements such as carbon, oxygen, and helium are consumed. This chain reaction of explosions fuels the star for millions or billions of years depending on the amount of gases there are.
Einstein and Newton are the most popular explanations of gravity to this day. After Einstein, there have been some new theories trying to disprove him. One new popular theory is called emergent gravity and it tries to explain the motions of stars in space. There are many conceptions about gravity that confuse many people. Many people believe space does not have gravity, which is understandable however this is false. Another common misconception is that objects that are farther apart have a strong gravity pull on each other, Newton proved this to be incorrect (“Gravity Misconceptions”). The simple basics of gravity are understood by scientists, but there is still no exact answer that explains just how gravity
Black holes were originally thought to have only mere mathematical concepts. There was seemingly no possible way to compress any object into a space small enough to equal to its schwarzschild radius. Later however, astronomer Subrahmanyan Chandrasekhar calculated that stars much larger than our own sun should theoretically be able to collapse into a black hole (UTFC). A star is like a blown up balloon with the force of gravity trying to compress the balloon inwards and the air trying to push the balloon outwards. Likewise, stars are held in balance by gravity trying to collapse the star inwards going against the outwards pressure of the internal reactions of the star called nuclear fusion. If the star is big enough and the pressure inside quickly disappears, gravity would and should slingshot the star into a tiny point with near infinite density with an extremely strong gravitatio...
Einstein himself, working at Princeton with Nathan Rosen had discovered that the equations of relativity actually represent a black hole as a bridge between two regions of flat space-time, a phenomenon known as the “Einstein-Rosen Bridge”. Later on, in 1963, the New Zealand mathematician Roy Kerr found that if a black hole is rotating, a singularity still forms, but in the form of a ring, not a point. It was believed that in principle, a particle may be able to fall towards the singularity, but if at some point moved through the hole instead of the ring, the particle may not be lost forever. Therefore, with these theories in mind, a particle falling into a black hole will fall through the ring that the singularity has become, then going through the Einstein-Rosen Bridge, eventually being spewed out of the white hole into another space-time continuum.
The Effects of Gravity There are some people who worry when they're outside, if they don't keep a good grip on the ground, they'll just go flinging off into space. They needn't really worry. about this, because gravity generally keeps that sort of thing from happening. The thing is, no one is really sure what causes gravity, but the effects have been studied by many. physicists and astronomers of the world.
Black holes are the result of the death of a massive star, leaving behind a dense remnant core that eventually collapses to create a gravitational force so strong that nothing, including light, can escape the force. The theory that black holes existed started back in the early 1900s and since then astronomers and scientists have been trying to get a better understanding of them. This phenomenon has been a working progress for astronomers and scientists for many years and as we develop a better understanding of our solar system, the more likely it is to make a significant discovery that can answer some of the most difficult questions about our incredible galaxy and solar system. The more information we are able to acquire about our universe, the more questions we might be able to answer about our existence. With advancements in technology we may be able to see some significant discoveries and insights into the world of black holes.
