Black Holes Research Papers

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.

Scary right? Well what about a black hole sucking in the earth, is it possible? Thankfully, black holes do not go around eating stars, moons, and planets. There is no black hole close enough to the earth for it to be able to be sucked into. If a black hole the same mass as the sun were to replace the sun, earth would still not be able to fall into it. The black hole would have the same gravity as the sun and the planets would orbit it, just as they do the sun. Also, the sun will never turn into a black hole, as it is not a big enough star to create one.

Throughout the modern era of astronomy, a single type of celestial object has puzzled astronomers more than any other. Black holes, whose existence was only verified in the early 1990’s, have fascinated scientists ever since Einstein first proposed the theoretical concept in the 1930’s. A black hole is an object so tiny, but also so dense, that it has the power to pull planets, stars, and even light into its core, and ultimately destroy everything in its path. Over the past decade much has been discovered about these enigmas of space and time; however, many of these recent discoveries lead to more unanswered questions. Nevertheless, the basic life cycle of a black hole is now understood in ways thought to be impossible only twenty years

Black holes are some of unusual and most interesting objects found in outer space. The first thing I learned, black holes are objects of the greatest density due to the strong gravity because mater has been squeezed into a tiny space. With the black holes relationships with mass and gravity, they have an extremely powerful gravitational force that even light cannot escape from their grasp if it comes near enough. Second thing I learned is about the inner region of a black hole, where its mass lies, is known as its singularity, the single pint in space-time where the mass of the black hole is concentrated. The third thing I learned that I found the most fascinating is if the earth ever falls into a black hole, one of the effect that will happen is “spaghettification,” which means if objects come too close to a black hole, it will stretch out, just like a spaghetti. This effect is brought about by a gravitational gradient across the object or a body. For example, if earth comes too close to a black hole, the nearest part of the planet will be pulled by an enormous gravitational pull, while leaving the farthest part with a small gravitational force. The fourth thing I learned is that the new hypothesis suggests that anything that touches a black hole will become an

Scientists do not have the ability to directly observe black holes with telescopes that detect x-rays, light, or other forms of electromagnetic radiation. However, Scientists can infer the presence of black holes and study them by detecting their effect on other matter nearby. If a black holes passes through a cloud of interstellar matter, it will draw that matter inward in a process known as accretion. A similar process will occur if a black holes passes a normal star. So, after a black hole is created, it draws in anything in its path adding to the extreme amount of matter that is packed into that very small area.

​The definition of a black hole according to Sea and Sky is “The collapsed core of a massive star. Stars that are very massive will collapse under their own gravity when their fuel is exhausted. The collapse continues until all matter is crushed out of existence into what is known as a singularity. The gravitational pull is so strong that not even light can escape.” Seasky.org, cited 2016: “Black hole”. Glossary of Astronomy. [Available online at http://www.seasky.org/astronomy/astronomy-glossary.html#B]. Black holes are not visible to the human eye. Since they are so dense, light is not able to escape them resulting in them being invisible. Special tools are required for them to be discovered and located with telescopes. This is done by seeing how stars close to them act different from others.

“Black holes are perhaps the most exotic objects to impinge on the cosmic consciousness. They are formed when matter such as that from a dying massive star collapses in calamitously under its own gravity. forming a region of space in which the gravitational is so strong that it swallows all matter and radiation that come near it.” - Christopher Reynolds (Anderson, 2010).

A blackhole occurs when a giant or supergiant start dies. But before the star dies their is a fusion reaction going on constantly throughout its life time. This fusion reaction can be di erent from star to star ff depending on its age. For a young star the reaction is a proton to proton fusion, a middle aged star can have a carbon reaction and a much older star, which is collapsing on itself has a helium fusion reaction. Once a star has finished reacting all of the helium it has the core begins to 'eat' it's self instead of the helium. This makes the core have a stronger and stronger gravitational pull. After the core has 'eaten or suck up everything into its fusion reaction it collapses due to so much compressed mass in a small space which forms a giant explosion creating a supernova which then turns into a singularity. Thus

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.

Black holes are in theory incredible frightening. One of the main reasons they are so monstrous is that they are one of the only thing in the universe able to trap light. The second reason they are so terrifying is that when you are being pulled into one you will be on a one way ticket train to emptiness. Therefor if there was a way to get out of a black hole what would it be? Then also if there was no way out what would it look like on the inside? Well some of these questions can be answered easily but for the others it will be a little more troublesome to answer. This is how, what, and why black holes are formed.

Well, the collision of 2 black holes as never been observed hear on Earth. The galaxy NGC 6240 is a super galaxy formed by the collision of 2 smaller galaxies. Since every galaxy has a supermassive black hole at the center of it, the NGC 6240 galaxy has 2 black holes at the center. Scientists are predicting that someday these two black holes would collide. There are two different outcomes of 2 black holes colliding. The first one is that if the 2 black holes are spinning at very high speeds and come together at just the right angle, the smaller black hole will be slingshotted away from the bigger black hole and sent hurtling through space. The second, more likely outcome is that they will slowly come closer and closer together until they can’t escape each others gravity and eventually become one, when this happens the resulting black hole is known as a “Binary Black Hole.” The energy emitted from the collision would be so great it would send ripples through the space-time fabric of the Universe. These ripples are known as “Gravitational

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,

The formation of supermassive black holes has been questioned in physics since the day of their discovery. Just how is something so large and powerful formed? Are they a danger to us? What lies beyond the event horizon? These are all questions that have been asked and not yet answered by astrophysicists. The first step to completely understanding these obscure creatures is finding out how they form, today's physicists are working endlessly to find an answer. Previous theories stating that supermassive black holes developed over time by ingesting large quantities of gas, have recently been found to be wrong. The most recent developing theory describes supermassive black holes forming by observing other black holes. There are two versions of

They are scattered throughout the galaxies. A stellar black hole is the product of the death of a giant star such as a pulsar or a neutron star. Black holes in general are very rare because most stars are not massive enough to create them. When a star stops producing fusion energy, the equilibrium of the star no longer exists. Without the star producing any fuel, there is no pressure created that can hold the star in place. The pressure that a star creates is used to prevent the gravity from crushing the core. Now that there is no pressure pushing outward, the gravity becomes so violent that it crushes matter to the point that it is completely destroyed. At this point, black holes are born. Black holes are created in rare occasions. During the death of most stars, they slowly dim out or explode into trillions of microscopic particles. For example, the sun, which is a red dwarf, will slowly die out. Eta Carinae on the other hand, located 8,000 light years away from Earth, is likely to explode within the next several hundred thousand

An accretion disk is formed when rocks, gasses and other satellites travel close to a black hole; they are sucked into the gravitational field (StrongGravity, 2013). A black hole is a place in space where the gravitational field is so great that not even light can escape it. This is because matter has been compressed into such a confined space; this can occur when a star is dying for example (Smith, 2008). Once trapped in the gravitational field the rocks and
