Black Holes 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 …show more content…
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 …show more content…
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.
First the mystery of the black holes and how they were created goes way back to when astronomers first discovered them. The astronaut said “he saw a blob of black matter and black holes are made when a star burns out or explodes but the astronaut never truly saw the actual thing. Black holes absorb light particles that are close enough to it so that it can thrive and continue. When a black hole goes away the light that it absorbed is turned into a new star. When an astronomer found a black sphere shaped cloud of matter in space he didn't really see it but he saw it pulling in large amounts of light that have been destroyed from an exploded star. If anything but light matter happens to get into a black hole it would just go through it rather
Is it possible for a black hole to destroy the earth or not? Since Black holes can happen anywhere and in any galaxy or solar system, I am out to prove that these terrifying singularities can or cannot destroy our earth, and why? From researching articles published by National Geographic, Sea and Sky, the National Aeronautics and Space Administration (NASA) and other publishers, I will conclude with black holes earth destroyers or not?
What causes black holes? This is one of the cool facts you will learn about black holes. This paper will discuss black holes, and how black holes form, what a black hole is, and how long they last.
Although the basic formation process is understood, one perennial mystery in the science of black holes is that they appear to exist on two radically different size scales. On the one end, there are the countless black holes that are the remnants of massive stars. Peppered throughout the Universe, these "stellar mass" black holes are generally 10 to 24 times as massive as the Sun. Astronomers spot them when another star draws near enough for some of the matter surrounding it to be snared by the black hole 's gravity, churning out x-rays in the process. Most stellar black holes, however, lead isolated lives and are impossible to detect. Judging from the number of stars large enough to produce such black holes, however, scientists estimate that there are as many as ten million to a billion such black holes in the Milky
When you are outside during night time and look up, you see thousands of stars of sizes, and color. Sometimes if you are lucky you get to see planets that also glow brightly such as Mars, Jupiter, Saturn, and so on. But there is one thing that is hidden from the naked eye and can make any of the things I mentioned, disappear. That thing is called a black hole. I am studying black holes because I want to find out how they affect us now and in the future, in order to help my reader understand I will explain how a black hole works, which will be useful to understanding how they can be used for space travel and how they are in the center of every galaxy.
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
Light is the fastest form of energy on earth which nothing can compare. But there is something that can consume this energy. This comes in the form of a black hole which will take the energy of the light and end the travel of speed. The mystery behind the black hole has people unsure what it truly is. Thousands of years ago, John Michelle, a British mathematician noticed the black star in the sky. In 1793 he described these dark stars as a hole that could omit energy faster than light, based on Newton’s laws of gravity (Talcott, 2016). Giving up on the black star, it wasn’t until Albert Einstein, 1915, with his theory of relativity that the initial explanation would begin on the black hole (Talcott, 2016).
Black Holes are the universe's most mysterious objects known to mankind. It lies in the darkness waiting and waiting for something...anything to come up and devour it without a trace. Black Holes are relatively new to humans, but we know that they’ve been here for millions and millions of years. Many people are unaware of the history of black holes, how a black hole is created and its function , and how there were theories leading up to black holes.
When many people think of black holes they think of a giant portal in space eating galaxies and moving on to the next as most commonly seen in pop culture shows such as Star Trek. The reality is however that while we spend a lot of time studying them we know very little about Black holes. What we do know is that there are two types of black holes based on their relative size, there are Stellar black holes and Supermassive black holes. Stellar black holes are only a few times larger than our sun while Supermassive black holes are about a billion times larger than our sun. Both types of black hole are formed when a star implodes and there is nothing left to burn. This can be seen by observing how light and matter cooperate with the event horizon, a second way to detect black holes is through X-Rays by noticing when stars rotate around a gap in space. By studying the speed of stars orbiting, and calculating their paths it is possible to determine the mass and size of a black hole. Using these pieces of evidence we can determine that stellar black holes do exist and
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.
There are two types of black holes that exist in our universe. The first one being the Schwarzschild black hole which happens to be the simplest one of the two. This black hole is considered the simplest because its core does not rotate which means the black hole is completely stable at all times of the day. The next black hole is the Kerr black hole, which happens to be the most common in nature. This black hole in contrast to the Schwarzschild black hole does indeed rotate. When the rotating star dies out and collapses, the core continues to rotate and therefore, that carries over to the black hole. Scientists believe that the smallest black holes formed when the actual universe formed and began. They also have been led to believe that the supermassive black holes that exist in our universe were made at the same time as the galaxy that they
Luckily it’s unlikely that black holes will swallow Earth. If a black hole swallows the sun, then the black hole would take the sun’s place. The black hole would take up the mass of the sun, meaning the planets would continue to orbit. But, this time the planets would be orbiting a black hole.
The year is 2185, scientists have just discovered how to teleport to any location in space in a blink of an eye. They have created a machine that can harness the abilities of a black hole to bend space time. This new invention revolutionizes the world and brings interstellar travel to mankind. Technology advances faster than ever and new discoveries are being made every day. Humans create an infinite energy source that will never run out and extend the human life. These abilities come from a wormhole in the center of a black hole. At this point in life’s existence, people have been able to look inside of a black hole which was thought to never be possible. While this may seem like a crazy science fiction novel that would only be seen in movies, it is theoretically possible in the universe. Black Holes are incredibly massive and mysterious, and could give mankind the answers to life’s biggest issues.
Albert Einstein first predicted black holes in 1916 with his general theory of relativity. The term "black hole" was coined in 1967 by American astronomer John Wheeler, and the first one was discovered in 1971. A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars. Scientists think the smallest black holes formed when the universe
Every day we look into the night sky, wondering and dreaming what lies beyond our galaxy. Within our galaxy alone, there are millions upon millions of stars. This may be why it interests us to learn about all that we cannot see. Humans have known the existence of stars since they have had eyes, and see them as white glowing specks in the sky. The mystery lies beyond the white glowing specks we see but, in the things we cannot see in the night sky such as black holes.
