Dark Matter And Dark Energy

  1. 1. By: Lian A.
  2. 2. <ul><li>It is about 20-25% of the total amount of matter in the universe </li></ul><ul><li>You cannot see the actual matter, although its effects are visible </li></ul><ul><li>It does not give off energy rays, so it is difficult to detect </li></ul><ul><li>Scientists know more about what dark matter is not, rather than what it actually is </li></ul>
  3. 3. <ul><li>It is about 70-99% of all energy in the universe </li></ul><ul><li>It does not posses qualities of “normal” energy (protons, neutrons, electrons) </li></ul><ul><li>It cannot be seen </li></ul><ul><li>It is thought to be the force that is causing the universe to expand </li></ul><ul><li>Scientists know more about what characteristics dark energy doesn’t have, instead of what is actually has </li></ul>
  4. 6. <ul><li>The pie chart on the previous slide shows the amount of dark matter and dark energy in the universe, although it might be inaccurate because it combines matter and energy into the same chart </li></ul>
  5. 7. <ul><li>Scientist had observed different areas in universe and noticed that there was an invisible force, that was doing strange things, without an explanation </li></ul><ul><li>They concluded that is must be a new type of matter and energy, which they latter called dark matter and dark energy </li></ul>
