Period 7 - Gah Tang - The Invisible Dilemma

  1. 1. The Invisible Dilemma <br />Presentation by: Gah Tang<br />SLC: Magnet<br />(The Study of Dark Matter)<br />
  2. 2. Dark Matter Defined<br />Misnomer<br />Dark Matter doesn’t really mean its “dark”<br />Invisible in terms of visible spectrum<br />Electromagnetic spectrum<br />Wide range from radio waves to micro waves to ultraviolet waves<br />Found through mathematical calculations<br />Thus commonly called the “missing mass”<br />
  3. 3. What’s so great about Dark Matter?<br />It’s in the nature of human beings to want to solve what we don’t know<br />Knowledge helps us progress as a society in terms of a better standard of living<br />Bertrand Russell said, “We know very little, yet it is astonishing that we know so much, and still more astonishing that so little knowledge can give us so much power.”<br />
  4. 4. Why Dark Matter? Continued…<br />Dark matter is another part of the puzzle to solving the mysteries of the universe<br />
  5. 5. Thesis<br />If we pursue Dark Matter, discoveries from studying it can:<br /> bolster our theories of gravity<br /> revolutionize the Big Bang Theory<br /> and lead to new discoveries like dark energy<br />
  6. 6. Gravity<br />The attraction of two mass<br />Discovered by Sir Isaac Newton<br />Bigger mass, Bigger attraction<br />Earth, Sun, Galaxy, etc.<br />Galaxies clump to form a spiral shape<br />Structure seems impossible<br />Without mass “holding” it with gravity, the spirals would not have formed. <br />
  7. 7. Big Bang Theory<br />Big Bang Theory has been proven to be the most reasonable theory that predicts the origins of our universe<br />Robert K. Soberman and MaruiceDubin<br />Invented theoretical cosmic meteoroids called cosmoids<br />Believe that Dark Matter consists mainly of cosmoids<br />
  8. 8. Big Bang Theory Continued…<br />Redshift<br />Used to describe the change in color to red of an object moving away from the observer<br />Used mainly to track the expansion of the universe<br />Soberman and Dubin predicts that cosmoids alter what we see as redshift<br />
  9. 9. Further discoveries<br />Dark Energy<br />Upon finding the theoretical Dark Matter, Dark Energy followed<br />Both Dark Energy and Dark Matter were found by mathematically calculating the mass and energy of the universe<br />Found that the numbers don’t add up<br />
  10. 10. Further discoveries cont…<br />More theories conjured just from dispute<br />MOND<br />Modified Newtonian Dynamics<br />Counters Einstein’s theory of relativity<br />Applies to slow accelerating mass such as galaxies<br />Would show to disprove dark matter<br />
