    Dark energy what is it? Dark energy is a unknown energy said to take up 70 percent of the universe. The energy is a repulsive gravitational effect that is causing the universe to accelerate out-ward. No one knows exactly what dark energy is or where it comes from. Dark Energy is a new idea. Little is known about dark energy, yet it takes up a huge amount if the universe. Scientist were able to show the universe was expanding at an accelerated rate by measuring the red-shift of an object by comparing

    Dark Matter and Dark Energy 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. Dark Energy is a mysterious force that drives the

    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 Way

    Dark matter is an invisible substance that makes up about 25% of the universe. Dark energy is the force that repels gravity which consists of about 70%. About 5% is the matter that we see today which includes stars and galaxies. Due to the fact that dark matter doesn’t interact with the electromagnetic force, dark matter doesn’t absorb, reflect or emit light. Dark energy doesn’t have local gravitational effects but it does affect the universe as a whole. The importance of dark matter and dark energy

    Universe. They did so by applying new technologies like computers and digital cameras to study and measure the spectrum and brightness of the light from other galaxies. The discovery proved the possible existence of a repulsive gravity force called dark energy that is responsible for accelerating the expansion of space. It challenged the previous assumptions of physicists whom believed that the expansion of the universe should be slowing down and it would eventually stop expanding or start contracting

    According to the definition given by the National Aeronautics and Space Administration, or NASA, the universe is a system consisting of all matter and energy, as well as all of the contents of space as a whole. (Dunbar, Canright) The birth of the universe resulted in the creation of all of the things that we know today, yet, its true origin is unknown. I know what you’re thinking. “If the origin of the universe is unknown, then how do we know how the universe began”? Well, this question has baffled

  • Big Bang Theory

    3881 Words  | 8 Pages

    According to the prevailing cosmological models that explain our universe, an ineffable explosion, trillions of degrees in temperature on any measurement scale, that was infinitely dense, created not on fundamental subatomic particles and thus matter and energy but space and time itself. Cosmology theorists combined with the observations of their astronomy colleagues have been able to reconstruct the primordial chronology of events known as the big bang. Quantum theory suggests that moments after the explosion

    world attributes the creation to God and quotes Steven Weinberg in saying that “science does not make it impossible to believe in God, but rather makes it possible to believe in God” (183). Using the big bang theory, the discovery of both dark matter and energy, and the idea that many features of the universe do come from nothing Krauss makes a convincing argument that the universe did indeed come about with no preexistence. In support of his thesis that the universe spawned from nothing, Krauss

    in with it. This will lead to the transformation of the universe to a huge black hole. Going into further detail, it is said that if the universe has large quantities of dark energy then the expansion of our universe could theoretically continue forever. Another valid point is that if our universe were at a loss of dark energy then gravity would have to eventually stop expanding; leading to contractions of the universe, which will continue until the matter of our universe collapses. This specific

  • The Existence Of Dark Matter

    1365 Words  | 3 Pages

    Dark matter has been argued about for a long time about whether it helps or not helps the universe. The universe is mostly made up of dark energy at 71.4%, dark matter at 24%, and atoms a 4.6%. These are the statistics made about the composition of the universe. However, these statistics were not always none. Einstein himself said that the universe was static, that the universe was neither contracting or expanding. When the Russian Mathematician, Edwin Powell Hubble, proved him wrong, Einstein said

  • Astronomy: A Fad Science?

    NOTE: This paper was written for an English class and a non astronomy audience. Thus, several arguments were left out to make the material easier to understand for the target audience. These arguments would include (but are not limited to) dark energy, dark matter, and the inflationary model of the universe. If I later have time I may revise this paper to cover such topics and be more comprehensive. Science is a field that prides itself on being objective. To help ensure that this objectivity

    Depression in To seem the Stranger, Fell of Dark, Carrion Comfort, and No Worst I believe that there can be seen a progressive deepening of depression throughout Hopkins' so-called terrible sonnets. The poems I intend to look at will show this, starting with "To seem the Stranger lies my Lot", "I wake and Feel the Fell of Dark", "Carrion Comfort", "No Worst, there is None", and finally "My own Heart let me more have Pity on". The first of the above poems shows the beginning of Hopkins' descent

    Use of Darkness and Light by Melville, Poe, and Hawthorne Melville, Poe, and Hawthorne all tend to focus on the darker side of humanity in their writings. In order to allow their readers to better understand their opinions, they often resort to using symbolism. Many times, those symbols take the form of darkness and light appearing throughout the story at appropriate times. A reader might wonder how light functions in the stories, and what it urges the reader to consider. If we look carefully

    The Dark Side of the Mind Exposed in Cask of Amontillado "A wrong is unredressed when retribution overtakes its redresser. It is equally unredressed when the avenger fails to make himself felt as such to him who has done the wrong." With that statement, Montresor begins his tale of revenge deciding that the act must be slow and sweet and that in order to fully enjoy it, his adversary must be aware of his intentions. Hidden within those same few lines, lies not only this horrid plan, but also the
