Black Holes Informative Speech

As this matter spirals into the black hole it creates what is known as an accretion disk, which accelerates and heats up emitting X-rays which can then be detected by astronomers.[6]

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

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

Singularities are amazing things to read about. First of all they spawn when a star dies and then form a black hole. Another thing is that they have no physical laws. They are at the center of a black hole and are what causes the black holed immense gravitational pull. They cause this amount of force because they are infinitely dense and infinitely small. They have an infinite number of atoms. Even though they have more atoms then all of this solar systems, atoms combined, they are still invisible to the naked eye and anything here on earth. They should not be

A black hole sends all legitimate and spam traffic to a null route stopping any packets being processed. Typically used to prevent DOS or DDOS attacks against services.

The sixty-symbols website has quite the collection of intriguing astronomical theories and interviews, but I specifically chose that of the black hole that contains interviews by Omar Almaini, Ed Copeland, Tony Padilla, Meghan Gray and Mike Merrifield from the University of Nottingham. The video began by a man revealing to his audience that he is often questioned about his personal opinion on black holes, which he informs us that “of course” he sees them as frightening and intimidating but goes on to refer to them as “cuddly”. Upon further explanation he points out two small (but different sized), round, black balls of fabric (that seemed to be knitted) that were gifts for his sister-in-law and they are meant to be representation of black holes with their solid black exterior. This seems like a useless example, but after thinking about it more critically I realize that I wasn’t

It is giant, rip in space in which everything is sucked in. A black hole sucks everything within a certain vicinity inside of it depends on how large it is. If a coin sized black hole were placed at the center of the earth, the earth would be destroyed. But not all of the earth would be sucked in only a partial amount. However all life on that side would be obliterated. Asteroids are a big factor in the role of destruction. Imagine yourself inside a drifting spaceship in the middle of nowhere and a giant rock is hurtling towards you. Pretty scary right? Well that’s pretty much what it feels like when an asteroid is hurtling towards you. If an asteroid hits your ship you’re pretty much screwed. The asteroid could puncture the ship and suck out all the air inside, then you will have to fix the exterior manually. Which exposes you to more problems. So asteroids are not a good thing. Air is also a big factor in space. What happens if your in the middle of exploring and your air runs out? I think you know. Red light flashing on the side of your helmet a rock has punctured your suit depleting you of your oxygen. Next thing you know your crew leaves you behind and you’re stranded on Mars. That's actually from a movie, but you get the point right? Good well, I haven’t covered all of space but if I were to we’d be here the rest of our lives! So that’s all i’m

Another theory for the creation of the supermassive black hole is the result of hundreds or thousands of small black holes that combine to make the supermassive black hole (“Black Holes: Facts”). A stellar cluster, group of stars, can also collapse in on each other to form a supermassive black hole (“Black Holes: Facts”).

Common types of black holes are produced by certain dying stars. A star with a mass greater than 20 times the mass of our sun can produce a black hole at the end of its life. Black holes are usually only created by the death of a very massive star. When a very massive star dies, it explodes into a supernova. The outer parts of the star are launched violently into space while the core completely collapses under its own weight. If the core remaining after the giant explosion from the supernova is very massive, there

According to NASA: What is a black hole – A black hole could not really destroy the earth because

Nothing can escape a black hole, even light it self. If two large amounts of gravity came to close to each other, they would distorted each other. There are two galaxies orbiting each other and one is stealing the stars from the other. The two galaxies pull at each other even if you can see it in motion. Stars in the galaxys get pulled apart and anything in the galaxy is most likely

For years black holes have been the work of science fiction, but a new development says that black holes are not just a mere myth, but that they lurk in the darkness in space. Black holes do exist because we have observed them, scientists have tested them, and they are remnants of giant stars. Black holes are a section of space where the mass of several billion of our sun's (depending on the size of the star) is crushed into a very small section. This causes the gravity to be so strong, even light cannot escape. This means that there is no reflected light, hence the name “Black Holes.”

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.

He sees the black holes as miniature models of a full scale universe. His idea that the implosion of the star could be related to the implosion of the universe. He wonders if the expansion of the black holes until their disappearance is relative to the expansion of the universe. This area seems to be a focused area of Stephen's work.
