Dark Matter And Dark Energy

To discover what the universe is made of and how it works is the challenge of particle

Astronomers believe there is enough dark matter in the universe to slow its expansion gradually toward a stop.

The universe of the past was understood to be a simple one-galaxy model that was both unchanging and immeasurable. Theories have constantly changed and been reconstructed to better portray the progression of human understanding over time. “The cosmos began

Throughout the second chapter of Investigating Astronomy: A Conceptual View of the Universe, authors Timothy Slater and Roger

In order to understand our place in the universe, we must understand the universe itself. Scientists, researchers, astronomers, cosmologists, physicists, amateur astronomers and a slew of other groups of individuals largely interested in the cosmos, help with discovering new and fascinating theories or proof of different phenomenon within the universe. Three scientific articles help readers to realize scientists are constantly deep in work to unravel the hidden truths. “Dark Matter in the Discovery Age”, “Why the Universe Had no Beginning”, and “What String Theory tells Us About the Universe” include theories vastly different from one another, but lead to the same conclusion; the universe’s creation.

In conclusion this unit on astronomy and cosmology helped me understand that there is so much more to the universe than I had initially thought. There is so much more that goes on and our knowledge will only increase as technology makes our ability to learn more about the depths of our

Every since I have read your book, Dark Matter, I have looked at reality in a whole different way. Every day when I make a sort of important decision I think what will happen if I take the other option which makes me quaver with fear. During the reading of this book, the plot was dispersing me causing me to try and regain the truth of the story. After finishing the book I was ravenous to hear what will happen next once the entered their new world and I felt like I was hanging of a precipice.

The particles include photinos, neutrinos, gravitinos, axions, and magnetic monopoles, among many others. Of these, researchers have detected only neutrinos -- and whether neutrinos have any mass remains unknown. Experiments are under way to detect other exotic particles. If they exist, and if one has a mass in the correct range, then that particle might pervade the universe and constitute dark matter.

The most common scientific explanation of how our universe came to be, is the Big Bang Theory. Around 13. 8 billion years ago there was no sign of anything apart from darkness. Until astronomer Edwin Hubble made a remarkable discovery about how the universe was created. Edwin Hubble hypothesised the matter and energy in the universe was initially condensed in a very small and infinitely hot mass. A huge explosion, known as the Big Bang, then sent matter and energy expanding in all directions (Howell, n.d.).

Dark Matter is revealed in many ways and one example of dark matter in action is how it holds our galaxies together. This is known because even though dark matter does not emit or absorb light or electromagnetic radiation, it does exert a gravitational force upon other galaxies, stellar clusters, and many other substances through the universe. One example of how amazing dark matter is is how it exerts a gravitational force upon stellar clusters. Stellar clusters are clusters of individual stars that move at rapid speed that are gravitationally bound. But it has been scientifically proven that the individual stars are moving too fast to be held together by the gravitational attraction of other stars. In this case dark matter provides the extra vigor that is needed.

As we progress as a species, we use more resources than the world can proportionately replenish. Third world countries such as Pakistan, Uganda, and Haiti are experiencing an energy crisis that is crippling to their societies. We must expand our horizons in order to save the place in which we live: Earth. If we are able to harness energies that are extraterrestrial, we may be able to break through into an entirely new era of technology. We have expanded outward as far as we can; it is time to expand upward into the universe. Dark matter and dark energy both make up a combined ninety-five percent of our entire universe. These are hypothesized materials that have been seen but not proven on a physical scale; however, they are literally holding

Even though dark matter is in existence we don’t have the instruments available to detect it yet. A theory suggests that dark matter is what actually makes up a large portion of our universe. Even though we can’t detect it, we know dark matter exists because it can interact gravitationally with visible matter and radiation. A professor from New York stated that dark matter plays a large role in causing geological catastrophes as well as mass extinction.

We consider the universe to be a dynamic sense of natural forces that are most effectively understood by scientific inquiry. We are always open to the discovery of new possibilities and phenomena in nature. However we find that traditional views on the existence of God either are meaningless, have not yet been demonstrated to be true, or are tyrannically exploitative.”

Dark Matter is a form of matter that is believed to account for approximately 90% of the matter in the universe. The majority of dark matter is non-baryonic in nature, being made up of some undiscovered particles. Dark matter has not been directly observed, but its presence is seen in a variety of astrological theories, including gravitational effects that cannot be explained unless more matter is present than can be seen. Most astrologists believe dark matter to be all over the universe and to have had a strong influence on its structure and evolution. The primary evidence for dark matter is that studies show that many galaxies such as our own would spread instead of rotating, or would not have formed or move as they do, if they did not contain

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.
