Dark matter

  1. 1. Dark matter and Dark Energy By: Derek Jacobs
  2. 2. What is dark matter? <ul><li>Scientists don’t know exactly what dark matter is but they know it exists </li></ul><ul><li>They know it exists because of how gravity is affected </li></ul><ul><li>Dark matter is matter that exists but can’t be seen </li></ul>
  3. 3. What does it do? Dark matter is attributed to it’s strong gravitational pull that tries to keep the universe from expanding Dark matter also accounts for about 23% of the universe. Normal matter only makes up about 4%.
  4. 4. What is dark energy? <ul><li>Dark energy is what fills 73% of the universe </li></ul><ul><li>Dark energy is pretty much the same as dark matter except for it is what’s causing the acceleration of the expansion of the universe </li></ul>
  5. 5. Dark energy (continued) <ul><li>Scientists can’t exactly describe what dark energy is because they can’t see it but they know it’s there </li></ul><ul><li>They don’t know if it’s an actual substance or if it’s just energy </li></ul><ul><li>Space isn’t empty it’s filled with all kinds of things and this is the biggest thing </li></ul>
  6. 6. What would happen if we were able to harness dark matter and dark energy? <ul><li>Scientists aren’t really sure what would happen but we would at least gain the ability to make things that are invisible to the human eye </li></ul><ul><li>We would probably be able to travel great distances in a small amount of time due to the expansion factor of dark energy </li></ul>
  7. 7. What I understood and questions I have <ul><li>Dark matter and dark energy is incredibly confusing </li></ul><ul><li>How can you prove something exists if it isn’t there? </li></ul><ul><li>Why do we want to harness them so badly? The benefits aren’t that rewarding </li></ul><ul><li>Why is there so much dark matter and dark energy and so little normal matter? </li></ul>
