Dark Matter Essay

Dark matter and dark energy are two entities that have very little known about them, except that they make up about 95 percent of the universe. Even though this is a large part of the universe, it wasn’t even thought about until the 1960’s or the 1970’s. This is because of the fact that it is very hard to detect and almost impossible to see. Although it is impossible to see, we can see the effects of them both in our galaxy.

“One explanation for dark energy is that it is a property of space” says NASA. Einstein was one of the first scientists to theorize about dark energy and how it was a property of space. If dark energy was a property of space it would imply that empty space isn't actually empty. Scientists theorize that this

Einstein has brought many insights of life including the theory of the speed of light, which has led to the special theory of relativity that molded the way science, is today. “For example, various experiments, including the Michelson-Morley experiment, failed to measure the expected changes in the speed of light relative to the motion of the Earth. Due to this Einstein recognized that light has a measured speed that is independent of the speed of the observer” (“Albert Einstein.” 4). “Einstein showed in 1907 that mass is related to energy by the famous equation E=mc^2, which indicates the enormous amount of energy that is stored as mass, some of which is released in radioactivity and nuclear radiations, for example in the sun” (4).This enabled Einstein to be able to start and finish the general theory of relativity.

“Introduction to Poetry” and “Traveling Through the Dark,” are poems written by Billy Collins and William Stafford. The poem’s, “Introduction to Poetry”, main conflict is a teacher who tries to get his students to read and appreciate a poem, but what all the students only care about is figuring out what it means. The conflict is highlighted through the many uses of metaphors to help us understand how he wants the students to look and decipher a poem and how they only focus on finding the meaning instead of taking their time to listen and see the art of poetry. William Stafford’s poem, “Traveling Through the Dark,” describes a driver’s dilemma of deciding whether to throw a dead pregnant deer into the river, or leave it laying on the road where it can cause an accident. In both poems, the use of literary devices such as metaphors, personification, imagery, and diction are effective in making and building up the conflict and reaching the resolution.

Rapper DMX was close to death when he was rushed to the hospital after he suddenly stopped breathing that led to his collapse. He did not have a pulse.

Dark Matter is a very interesting book that I would recommend you to read. The author of Dark Matter has both assimilation and tolerance in the book. In the book tolerance is used by Jason having to survive in different situations. At one point in the book he goes to a world that is covered in snow. He built tolerance to the cold and was able to carry Amanda to a cabin and survive. But also has assimilation sprinkled in. Jason had to adapt to his doppelgangers and their worlds.

The properties of regular matter include a composition of neutrons, protons, and electrons; it can be seen and touched. The properties of dark matter are unknown; dark matter cannot be seen, touched, interact with light, or produces radiation. Dark energy is also an unknown entity, but it is considered a form of energy. Dark energy is also known as the energy of nothing or the energy of empty space. Even so the big bang theory is still widely accepted among people as the start of the universe

Dark matter is an element which is non-luminous and cannot be identified directly by electromagnetic light but can be identified. Dark matter is believed to be the fundamental element that makes up the universe, and that could probably be the reason why it is difficult to separate it from other particles.

The Hubble helped scientists to discover that dark matter is the key to why galaxies are moving away from each other (Space.com

No school in the country gets more research funding than Johns Hopkins, and as a result no other university would be able to provide me with as many incredible research opportunities. Although I am excited by the opportunity to learn new and fascinating information inside the classrooms of Johns Hopkins, my true passion lies in doing research during college. I have always been intrigued by mystifying concepts such as general relativity, dark matter, and black holes. The learning atmosphere at Johns Hopkins University will encourage me to pursue these mysterious subjects by working on research with the brilliant minds of professors and other

I have learned many new things from the reading of Bad Science. I have a few of them that I will discuss because they caught my interest.

But studying these masses as well as other things in the universe helps us to understand the universe and its fate. Which is why a press release by the National Radio Astronomy Observatory (https://public.nrao.edu/news/pressreleases/brown-dwarf-jets)

Dark Matter and Dark Energy are important. They can help us know how the universe began. These two are the mysteries of the universe; they compose about 90% of the universe. They are mysteries because we believe that they exist but we can’t see them or detect them. People question whether they manifest to be the same thing. Astronomers know very little about their constitution so they cannot assume they are related.

The fact that the stars are confined within the galaxy, even though their vertical velocities are measured to be high enough, necessitates the presence of unseen mass in the galaxy” . Swiss astronomer, Fritz Zwicky, in 1933 was investigating a galaxy cluster. “While making his investigations in the galaxy cluster at Coma constellation 90 Mega parsecs (one million parsecs) away and also at the cluster in Virgo constellation and calculated its gravitational mass using the “Virial Theorem.” (2T=n{Vtot} “He then used the mass-luminosity relation of the stars of the individual galaxies and estimated the mass of the luminous matter in each of the clusters. He came up with a huge discrepancy between these two masses and predicted the existence of dark invisible matter. “ He would call this invisible dark matter, dunkie Materie. At the time of this proclamation was not widely accepted until a “Bullet Cluster” was observed. “Authors report that the cluster is undergoing a high-velocity (around 4500 km/s) merger, evident from the spatial distribution of the hot, x-ray emitting gas, but this gas lags behind the sub cluster galaxies. Furthermore, the dark matter clump, revealed by the weak-lensing map, is coincident with the collision less galaxies, but lies ahead of the collisional gas. This and other similar observations allow good limits on the cross-section of the self-interaction of dark matter.” Now that we have an
