    Dark Matter

    • 546 Words
    • 3 Pages

    Dark matter and dark energy are perhaps the biggest mysteries in the universe. Dark matter makes up 26% of the universe, dark energy makes up 69% of the universe, and ‘normal’ matter- everything visually observed in the universe- makes up only 5% of the universe. Dark matter and energy are thought to be explanations for various phenomena that have been observed in deep space. Dark matter is matter that cannot be detected by its absorption or emission of electromagnetic radiation. Scientists currently have a very dim understanding of exactly what dark matter is, but one theory is that dark matter is made up of exotic particles that don’t behave like ‘normal’ matter, but still exert a gravitational pull. They believe that dark matter exerts a gravitational pull because the amount of ‘regular’ matter in the universe, and ‘normal’ matter…

    Dark Matter

    • 507 Words
    • 3 Pages

    Dark matter is matter that cannot be directly seen because it does not interact with light. This mysterious matter makes up the majority of mass in a galaxy. Although we cannot see dark matter we know that it is out there because we can see it effecting the motion of the stars in a galaxy and gravitational lensing. The first piece of evidence for dark matter is in the way we have observed galaxies moving. You would likely expect their behavior to replicate that of the Sun and the planets, with…

    Essay On Dark Matter

    • 1945 Words
    • 8 Pages

    Dark matter leaves astronomers and physicists baffled as to what it possibly could be. Scientists design experiments to attempt to figure out what it is, but no one truly knows what composes dark matter. Physicists are so interested in understanding dark matter because it accounts for the formation of the Universe, as observable through studying the distribution of gravity within galaxies (Carnegie). Original attempts at studying dark matter referred to dark matter as baryonic, which is a word…

    Hairy Dark Matter

    • 942 Words
    • 4 Pages

    Dark matter and dark energy are phantoms of the scientific community. The scientific community has tried to detect dark matter for decades. Hairy dark matter could be the key to the secrets of the Big Bang and the events that occurred afterwards. Condensed filaments of dark matter, hairs, in our galactic neighborhood could be used to gather incredible amounts of data that was previously unavailable to us. Hairy dark matter is a type of dark matter, formed by the gravity of space objects, that…

    What are Dark Matter and Dark Energy? Introduction: To start with, Dark Matter is invisible material that permeates the galaxies. It exerts a gravitational influence on the stars causing them to deviate from Newton’s and Kepler’s laws. Dark Matter also affects members of a group of galaxies. The nature and composition of the Dark Matter are unknown. In space there is a lot of totally empty space, the vacuum, which contains energy. This energy is variously called Dark Energy and also may be…

    One concept that has interested is dark matter and dark energy. Dark matter is the thing that makes it possible for galaxies to exist. When astrophysicists and cosmologist calculated why the universe is structure the way it is, it became clear that there’s just not enough normal matter. The gravity of the visible matter is not strong enough to from galaxies and complex structures. The starts would more likely be scattered all over the place and not form galaxies. Therefore, cosmologist concluded…

    Energy Vs Dark Energy

    • 1566 Words
    • 7 Pages

    Dark energy is a term scientists use to describe the unknown source of energy which causes the universe to accelerate outwards rapidly, causing the known universe to expand. This is another concept which is directly applicable to the theory of increasing entropy in the universe. The universe is theorized to have begun in a much more condensed and orderly state and began to expand and accelerate outwards from the origin point of the universe. As the universe continues to expand, it also becomes…

    Hubble Space Telescope

    Space is a huge sea of unknown. We are simply specks of dust, trying to figure out the behaviors of giants. Thus it is apparent that the specks can not know much. For now. One of the biggest mysteries is the expansion of the universe; in the 1990s, we knew that theoretically, our ever-expanding universe was slowing down due to gravity, and that it would eventually collapse or keep expanding, just slower as time went on. However, thanks to the Hubble Space Telescope, we now know that to be dead…

    the Edge of the Universe. Youtube. Google, 20 July 2006. Web. 20 Apr. 2017. . 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…
