Black Holes: What Scientist Know About Them Essay

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.

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

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 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).

Black holes are strange because we can not see them because they have such a strong gravitational pull light can 't escape from. They can rip anything apart. Black Holes form when a star dies and collapses in on itself. They are usually relatively small and really dense. 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. In the milky way their are a few hundred million black holes. In recent years, NASA instruments have painted a new picture of these strange objects that are, too many, the most fascinating objects in space.

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.

3. Which feature is found with Kerr black holes but not Schwarzschild black holes? An Ergoregion is found with Kerr black holes but not with Schwarzchild black holes

Astronomy is defined as the branch of science that deals with celestial objects, space, and the physical universe as a whole. In this article, the astronomers figure out when a collision occurs by measuring the gravitational waves in space. The astronomers are also starting to look at why black holes pair with each other. This can help astronomers predict which ones will collide in the future if they are able to figure out why certain ones collide.

Black holes can be scary to think about, but amazing at the same time. The fact that they can have such a heavy gravitational pull that not even light can escape is fascinating. Luckily we will probaly destroy Earth before a black hole eats it

Black holes had always piqued my interests, from when a small child intently devoured documentary to documentary to when a confused teenager encapsulated herself in a black hole of her own. The science of the black hole transfixed my childhood sense of curiosity, but especially the point that the scientific world labeled the “singularity”, the point at which gravity became infinite.

Black Holes The term black hole was first used in 1969 by the American scientist

Black holes are one of the most mysterious aspects of the Universe. Scientists know that black holes contain an insane amount of matter packed into a small space with a gravitational field so intense that not even light can escape it. This review will focus primarily on what is known about black holes, how scientists know black holes exist, current studies and experiments, and why they are studied. Based off the knowledge humans have already uncovered about black holes, they could change the future. Black holes could realistically be used to power starships, enabling humans to travel at near light speed to explore the Cosmos. Humans would be able to conquer the most unknown frontier yet.

The magnificent life of a black hole. The black hole is a mystery that you will want to learn about. A black hole does many wonderful things in outer space. Black holes in outer space have been a mystery for years. There are many questions such as how is a black hole born and how does a black hole grow.
