Dark Matter Essay

Dark Matter Some scientists now believe it is not the matter we see, but the matter that hides in the dark that holds the true secrets of the universe. There is a mysterious dark matter that binds stars and galaxies together, and this matter might be made up of WIMPS, MACHOS, and axions. Physicists continue searching for dark matter, and particles that make up dark matter. Dark matter has strange characteristics and behaves quite differently from ordinary matter. Understanding dark matter is essential

15. Dark Matter and Dark Energy (1500 to 2000 not including references) Explain both concepts and the differences between them. Describe the observations that led to the hypothesis that dark matter is an important component of the Universe. Describe the suggested constituents of the dark matter. There have been many attempts to understand the world we live in, ranging from studies of objects as small in size as DNA to the study of massive objects as galaxy clusters and even the whole universe.

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 way that we can “see” the dark matter is the movement of the Milky

Dark matter and dark energy are imperative links to the building blocks of our universe, yet presently we know so little about them. In reality scientist know more of what dark matter and dark energy could not be than what it could be. Dark matter and dark energy are two utterly separate components, but work together as one unit. Dark matter is what holds the universe together, and dark energy is what draws the universe apart. However without both dark matter and dark energy our universe would not

Dark matter and dark energy are some of the most mysterious forces in our universe. They encompass around 95 percent of our universe, however, the human race is blinds to the truth of their existence. What we truly know about the mystery that is a majority of our universe is near insignificant compared to the possibilities that exist. We know that they exist and that they do something. Their discovery wasn’t even a sign of humanities dawning intellect, it was a mere accident. The scientific community

“Dark energy comprises 69% of the universe, dark matter makes up 25%, and ordinary atomic matter only makes up 5%,” (Spergel). For centuries, scientists have been gathering innumerable amounts of information to comprehend the elaborate universe. A handful of these observers have detected invisible forces comprising space. Countless amounts of astronomers have tried to explain this dark mystery. In 1917, Albert Einstein was able to add the cosmological constant to his general theory of relativity

Solar System that is causing the planets to alter their trajectory. This lead scientists to believe in the existence of dark matter and so began investigations and experiments to learn whether it actually existed or not (Start with a bang, 2013). Concepts and differences- The theory of dark matter stems from the fact that there is not enough normal matter, as the gravity of normal matter isn’t strong enough to form galaxies and complex structures. The stars will more likely be disorganized and not form

The Universe: Dark Matter and Dark Energy 1. Fritz Zwicky is credited with being among the first to grasp the significance of dark matter in 1933. He found this "missing matter" by measuring the motions of the Coma Cluster. Sean Carroll states that Zwicky began his measurements by "estimate(ing) how much mass there was in that cluster. Then he compared it to how much mass you could actually see by looking at the galaxies." (The Universe) The narrator continues by reporting that something was wrong

“Dark matter is a hypothesized form of matter particle that does not reflect or emit electromagnetic radiation. The existence of dark matter is inferred from gravitational effects on visible matter, such as stars and galaxies”(Andrew Zimmerman Jones). Dark matter is crucial to the study of the universe and the existence of the human race. Since either dark matter or dark energy have neither been actually observed and all theories, we will be evaluating them from scientific standpoint. Since most

A Study Of Dark Matter Contribution to the Universe and Dark Matter Candidates Aditi Sharma, Boris S. Kalita, Harshit Sharma, Rohit Kumar Singla Abstract Dark Matter has been one of the most researched topic in the recent era of science. Even though we have observed e ects of this exotic entity, we are yet to understand its structural form. Thus we are forced to hunt for clues that would help in a better understanding of this component which forms 26:8% of the entire universe. This report delves
