NASA: The Mystery Behind Black Holes

A black hole is a point in space where there is extreme gravitational pull, so extreme that light itself cannot escape. The strength of gravity is so strong due to the fact that an immense amount of matter has been contained in a small space.

This paper will introduce you to the incredible topic which is black holes. A black hole is a region of space time exhibiting such strong gravitational effects that nothing can escape from inside it. (NASA) No human has ever entered a black hole and there is still a large mystery about them; we have very little idea of where the matter that enters them goes. A black hole cannot be looked into either, as it sucks all the light into the middle of it. Space programs use special satellites with certain features that allow them to see these black holes. A black hole can be big or small, sometimes forming when a star is dying. Some scientists speculate that there can be black holes just 1 centimeter large. There are multiple types of

No school in the country gets more research funding than Johns Hopkins, and as a result no other university would be able to provide me with as many incredible research opportunities. Although I am excited by the opportunity to learn new and fascinating information inside the classrooms of Johns Hopkins, my true passion lies in doing research during college. I have always been intrigued by mystifying concepts such as general relativity, dark matter, and black holes. The learning atmosphere at Johns Hopkins University will encourage me to pursue these mysterious subjects by working on research with the brilliant minds of professors and other

Black holes should probably not be called black holes. In fact, black holes are anything but empty space. Black holes are a great amount of matter packed and squeezed into a very small area. The result of this amount of matter squeezed into a small area results in a gravitational field so strong that nothing, not even light, can escape.

A black hole is a region in space where the pulling force of gravity that is so strong that the region cannot escape. This compression can take place at the end of its stars life. Some black holes are a result of dying stars. How every space telescopes with special instruments can help find black holes. They can observe the behavior of material and stars that are very close to black holes. Black holes can come in a rage of signs, but there are three main types of black holes. The black holes mass and size determins what kind it is. The smallest ones are known as primordial black holes. Scientists believe this type of black hole can be up to 20 times greater than the mass of the sun and fit into a ball of about 10 miles. The largest black holes are called supermassive. Supermassive black holes are at the center of the milky way galaxy is called sagittarius. A black holes gravity can be as strong to pull off the outer layer gass of the star and grow a disk. The

Black holes are a staple in the study of our unknown universe. The current understanding of general relativity allows something like a black hole to exist due to the strange properties surrounding them, as well as the effects on their surroundings. Black holes are defined by Chaisson's Astronomy as "a region of space where the pull of gravity is so great that nothing, not even light can escape" (Chaisson, 2013). This definition is very broad, simply stating the effects of what we call a black hole. Indeed, there is a lot of thoughtful assuming done when discussing this phenomena, however, what if everything we thought we knew about black holes was wrong and black holes didn't actually exists. That is exactly what a small group of scientists and astronomers think is the case.

Of course, as intriguing as a black hole’s effects within in and around galaxies could be, we must also keep in mind that some theorists believe black holes are responsible for producing, Dark Matter. As stated by the “The Gale Encyclopedia of Science”, in their article, “Dark matter”, Dark matter is, “material that does not emit or reflect light and that is therefore invisible” (The Gale Encyclopedia of Science). Scientists believe dark matter and black holes are in relation, because recent studies done by Russian astrophysicists Vyacheslav Dokuchaev and Yury Eroshenko, institute that, “dark matter could be made of microscopic — or quantum — black hole atoms (Dokuchaev, Eroshenko). In a sense, making it dark, however, as reported by the “World of Scientific Discovery”, in their article, “Dark matter”, “dark matter does not behave like ordinary matter, such as dust or gas, which leaves traces by emitting, deflecting, or absorbing electromagnetic radiation” (World of Scientific

Black holes are measured in a measurement called solar masses. A solar mass is how much are sun weighs and black holes can weigh millions to billions of these. Black holes can be ten to one hundred solar masses. But that is only for black holes that are primordial or stellar. But supermassive black holes can range from millions to billions of super masses and this is what leads scientist to believe that they are formed in the center of every galaxy. The supermassive black hole in the center of the Milky Way, Sagittarius A is scaled at 4.3 million solar

The common conceptual intuition of black holes includes the fact that they attract matter with great force in such a manner that it engulfs everything in its proximity. The concept of accretion disks and as we shall see, particles escaping the gravitational potential,

A supermassive black hole is somewhat an extreme form of a black hole; however, they are more common than one would think. Supermassive black holes sit at the center of every galaxy, including our own. They are what keeps the stars and solar systems in the orbital of the galaxy. The two seeding theories (big and small) are a reasonable, current way to describe the formation of these extreme beings. The small seeding theory summarizes that the black hole slowly eats smaller black holes to enlarge its size, this theory is valid but violates certain placed laws in physics that are more than likely, not to be broken. The larger seeding theory states that the density of dark matter at the beginning of the universe attracted large gas clouds and cut off the formation of smaller stars. This gas cloud then collapsed to form and extremely large star, that then collapsed once more to for a black hole that attracted more gas and other particles. This theory is believed amongst astrophysicists but it is also denied by some, saying that the dark matter has nothing to do with the massive star formation, and that a black hole can form by an average star collapsing and gaining excessive

Throughout the lifespan of galaxies and universes, interstellar objects are created and destroyed including stars, asteroids, nebulas, and black holes. One of the rarest interstellar creations are black holes, of which are only found in three forms. These three forms include stellar, supermassive, and intermediate black holes. Black holes are mysteries that were not fully understood until the beginning of the 20th century, when multiple scientist focused their research on them. They predicted theories and made many discoveries. These scientists include Sir Isaac Newton, Albert Einstein, John Wheeler, and Stephen Hawking. These scientists have helped us to quickly advance our knowledge on the universe and surrounding galaxies.

Black holes come in various sizes ranging from the size of an atom to black holes with 5 million times the mass of the sun. Black holes are usually small but they have

To begin, one type is a stellar black hole (“hubblesite” 1). Stellar black holes come from the collapsing of a massive star. Another kind of black hole is a supermassive black hole that has the mass of one billion Suns. Next, there are intermediate black holes, which are mid-sized (“science.nasa” 1). Astronomers have a theory that miniature black holes may exist and are smaller than our Sun (“hubblesite” 1). It is unknown if the theory is true or not. Finally, scientists have discovered some black holes spin while others stay stationary. A spinning black hole rotates around its axis while a stationary black hole do not spin at all. As astronomers have studied the differences of black holes, they have gained additional

A quasar is defined as a massive celestial object, producing large amounts of energy and light. These are believed to contain massive black holes in their centers. These large celestial objects were thought to be abundant at the early beginning of the universe, but now have slowly turned dormant (Shields and Kormendy).There are multiple kinds of black holes that exist in our universe, one of them is a quasar as previously stated. These black holes exist in a massive ball of gasses and dust that is used as fuel for the black hole. These objects can be thousands of times brighter that even the brightest star found due to the extreme amount of energy released (Mari 56). They are often found at the centers of galaxies and are credited towards the early formation of the universe. They then run out of fuel and continue to be the strong gravitational force at the center of most galaxies holding them together (Shields and

Another method in physics on how to time travel is through black holes. A black hole has been discovered by Einstein's theory of general relativity, which showed that when a star dies, it leaves behind a small, dense remnant core. If the core’s mass is more than the sun, the force of gravity overwhelms all other forces in which it transforms into a black hole. Scientists have said that black holes can destroy anything that goes in it and it could be hard to get out of a black hole, once something went in it. In an interview by physicist Lior Burko, he states, “One possibility is that black holes may allow us to travel to very remote places in the universe, or another universe entirely,” (Kahney, “Black Holes and Space Time”). Black holes may have evidence that there are different kinds of parallel universe. Even though it is still unclear what black holes can do as in destroying everything that it goes in or if it leads someone to time travel into another parallel universe. Scientist are trying to create a black hole, here on earth, to see what blacks can do as in sending information to another universe.
