Black Holes And The National Aeronautics And Space Administration

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.

Due to the strong gravity pulls, all of the light around a black hole is sucked into the middle. Scientists can see how the strong gravity affects the stars and gas around the black hole however, study to see if the stars are orbiting the black hole. (Space) This is how they know they exist, by studying the stars around them. Also, when a black hole and a star are close together, a high energy light is formed, which humans are incapable of seeing. However, satellites and telescopes can see these high energy lights, allowing us to spot black holes

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.

The supermassive black hole in its center is a billion times heavier than the Sun. Although the galaxy is relatively distant (300 times further away than the Andromeda galaxy), it appears to us as the second brightest radio source in the entire sky. This is because the black hole generates tremendous energy as it consumes large amounts of material. Nearby electrons are accelerated in this process, emitting strong radio waves as they spiral outward in magnetic

Black holes have been theorized since 1916. However, no scientist has ever discovered a black hole in certainty. In theory, A black hole is created when a star of three or more solar masses collapses. “One solar mass is equal to the mass of the sun,” (Mclintock 1). A star collapses when the outward push of the combustion reaction no longer has the required forces compete with the inward pull of gravity. Most astronomers believe that the Milky Way contains millions of theses invisible devils, which are massive stars that have collapsed. In theory, anything could become a black hole if it were simply compressed into its Schwarzschild radius. For instance, Mount Everest has a Schwarzschild radius that is less than a nanometer,

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

There is proof that black holes do eventually disappear. But for most black holes this time for them to disappear is unimaginably long. But if there were to ever be a black hole the size of a cruise ship it would evaporate in the time of seconds. Because the flash of light that is created from all the light that is on a subatomic level being created or destroyed. This is irrelevant to any black holes in the universe because there is no known black holes the size of a cruise ship and the temperature that this light gives of is almost zero degrees and the energy loss is

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 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

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

Stellar Black Holes: It is consisted when the middle of a very massive star collapses on itself. This collapse also causes a supernova that explode a part of the star into space. (Mathew,2012)

As more material is pulled into a black hole, it grows bigger and its gravity strengthens (Sipiera 29). Also, a black hole’s gravitational pull is so strong that light can even be pulled into the hole (Jefferis 4). Next, black holes are the last step of the life of a star. Although a black hole’s gravity is strong, only a small part of space will be swallowed. Because black holes are able to pull light into themselves, they cannot be seen. These are a few of the facts that scientists have uncovered.
