Dark matter Essays

Dark matter is just what it’s name suggests; a complete mystery. More is unknown than is known about dark matter, though it is said to make up more than 27% of the universe. The existence of dark matter has only been inferred from the gravitational effect it appears to have on normal matter. Scientists are led to believe that dark matter does not interact with the electromagnetic force since zero light can be reflected, emitted or absorbed, which in turn makes it nearly impossible to detect.

apart from each other? How does dark energy impact the expansion of the universe? The Mysterious Force that Controls the Universe Why are all of the gravity bound systems in the universe being pulled away from each other? The observable universe is defined as a spherical

Project Note Sheet Grace: What is dark matter and dark energy? The universe is approximately 68% dark energy, 27% dark matter, and 5% normal matter. Dark Energy: Scientists do not know a lot about dark energy, and this is ironic because it makes up most of our universe. However, as the universe has expanded, it has expanded faster than ever before. One theory that explains this is that a large dark energy force is pulling it apart. Dark Matter: Dark matter can’t release or reflect light; however

the Bootes Void, scientists are able to find resources of dark energy and matter. Dark energy is an unknown form of energy that is said to be the reason why

Does the fish know that it is in water? That is a saying that really strikes thought into one’s mind. Can an organism be truly aware of something that is beyond itself, or something that has been a given truth since its birth? This thought provoking remark indeed that bears a lot of resemblance to the overall theme in Science Set Free, written by award winning novelist and heavily respected biologist, Dr. Rupert Sheldrake. Within the book, Sheldrake’s main concern is that modern day scientific beliefs

I read the book Einstein's Telescope the Hunt for Dark Matter and Dark Energy in the Universe by Evalyn Gates. This book is about the foundation of our universal principles, and the unknown we are striving to find, as well as the search for the fuel source of the expanding universe, dark energy. The book also gives a firm foundation for people who don't have a basic understanding of universal principles, and simplifies complex terms to an understandable level, such as when the author says,”imagine

Gage Newton English 10, Period 6 12 October 2015 Dark Holes Dark gaps are the most grounded matter individuals know to date. Understanding how they are made, What they are, and how they are formed. How They Are made? They are produced using a Stellar Star. Made when the focal point of a major star falls in upon itself, or breaks down. At the point when this happens, it causes a supernova. A supernova is a exploding star that impacts some portion of the star into space. (Nasa.com) At the point

A whole 10 to 15% in fact the rest of which is made up of its many stars. Scientist believe that we can only see 10% of its mass with the naked eye due to the belief that the other 90% is made of dark matter. This dark matter is the cause of the galaxy’s mysterious halo stretching for hundreds of thousands of light years, However it only contains about 2% the amount of stars found in the actual disk itself. “At the center of the galaxy is the galactic bulge

one axis can be longer than the other. They can be nearly circular or so lengthened which can make them sometimes take on a cigar-like appearance. Elliptical galaxies can contain up to a trillion older stars and little dust and other interstellar matter. Their stars orbit the galactic core, just like the disks of spiral galaxies, but in more random directions. The universe's largest known galaxies, elliptical galaxies, can be as much as two million light-years long. Elliptical galaxies can also very

You may be asking yourself what is this thing that many astronomers (unlike myself) call a “Black Hole” (the weird thing pictured above), well I’m here to help you out dear reader. A Black Hole is simply (or maybe not simply) a region in space where matter has collapsed into infinite density. As a result of this spacetime experiences an extreme curvature. Because of this black hole the gravitational field of that black hole becomes so intense that light or really anything else cannot escape from it

or not... Space. What exactly is space, such a mystery. Full of darkness, planets, marvelous, beautiful, and intriguing. Space is a vast place which few have explored. So why, why do we explore? What’s the point? Space is a vast empty place that has been explored by few. Yet humans have been prioritizing this issue for years now and yet we have not found a place capable of being inhabited by humans. So why do humans continue this knowing that it would take years and years to even reach the planet

The hollow earth theory or ‘hohlwelttheorie’ as it is called in German, is the idea that the Earth is not a solid mass but rather an entirely hollow sphere that within contains a substantial interior space. The idea goes back to ancient mythology, folklore, and legends of a subterranean land inside the Earth, from which places of origin and afterlife were thought to be located, such as the Christian hell described by Dante, the Greek underworld, the Hindu ‘Patala’, the Celtic ‘Cruachan’ just to name

The Fermi Paradox The Fermi Paradox, inaccurately attributed to physicist Enrico Fermi, suggests that if intelligent extraterrestrial life exists, there would be evidence of their visits to Earth, or presence in the galaxy and/or universe, but since there is no clear evidence, intelligent extraterrestrial life either does not exist, or some other explanation is required to explain the lack of evidence. The name of this concept improperly originates from the physicist, Enrico Fermi, who asked, “Where

Supermassive Black Holes (Not Explained by Muse) Space is a mystery and we will never know all the answers to the universe and what's inside of it. However, we've learned a lot about our surroundings in the past few hundred years and we continue to advance further into the depths of the universe. We saw stars in the night sky and we researched, we saw distant planets and we travelled there, we saw distant galaxies and we researched some more. One thing we came across were the middles of great galaxies;

In Neil Degrasse Tysons book, “Death by Black Hole”, he says states something quite intriguing. “Without a doubt, the most spectacular way to die in space is to fall into a black hole. Where else in the universe can you lose your life by being ripped apart atom by atom?” Black holes are regions of space (and of space) where the gravity is so high that the fabric of space and time has basically curved in or collapsed on itself. The very first black hole found was Cygnus X-1 that is roughly 6000 light

Einstein’s calculations to show just how the universe would act under the theory of ‘general relativity.’ Even though Friedman got so far, he was still missing something to complete his research. He did not know the force of pressure or the density of matter throughout the universe. He is considered one of the most important developers in the BigBang Theory. In the 1924 Hubble came to the conclusion that the faint lights that were seen were in fact lights from other galaxies. This discovery helped to

A Warp in Time and Space In space there are giant masses where no light can escape. Usually these gigantic dark masses are surrounded by dust and gas of all colors. There may be stars nearby, but in this dark mass nothing can be seen, only black. The masses cannot actually be seen at all without the dust and clouds around them, as they do not give off any light because their gravitational pull is so strong that all the light is pulled in. These are called black holes. A black hole is a very unique

Assessment of Pharoah Rivers (There Are No Children Here) Boimah B. Karmo Neberaska Wesleyan University Abstract Pharoah Rivers is a nine-year-old boy and the fifth of eight children. He is like any other nine-year old child that loves to play and seeks daily challenges. Pharoah and his family live in Chicago in the Henry Horner projects; a public housing complex that's overflowing with gangs, drugs, and the infliction of pain on others. Pharoah stays with his mother, LaJoe, and his siblings. His

Jack Dempsey was a 33 year old man from Cleveland, Ohio. In 1995, police showed up to a house fire and firefighters pulled Dempsey from out of the basement unconscious from severe smoke inhalation. He went to trial and was found guilty of aggravated arson and burglary. The prosecution concluded that Dempsey had left a strip club after he had been drinking and broke into the house and set fire in two different places. As he tried to escape, that is when he collapsed. A urine test had found high levels

DEFINITION AND DESCRIPTION OF THE TASK The researcher will conduct an inflated balloon experiment. This experiment will allow the audience to understand clearly, "Charles' Law" and "Kinetic Molecular Theory" respectively. It will use extremely low and extremely high temperature so that the audience can evaluate the significant difference on the balloon size. The students shall be competent in presenting a laboratory experiment because it is one way to get involve in the lessons taught in school
