Dark matter and dark energy

  1. 1. Dark Matter and Dark Energy<br />By: Isaac Lodise<br />
  2. 2. Dark Matter<br />Dark matter is invisible matter that we can’t touch, or hear, or see at all. <br />Dark matter makes up 80% of the universe<br />It affects the rotational speeds of galaxies, the temperature distribution of hot gas, and the gravitational lensing of background objects(gravitational lensing is the curving of light because of the gravity of a very large object.)<br />
  3. 3. Dark Energy<br />Dark energy is a hypothetical form of energy that covers all of the universe.<br />It is what increases the rate of expansion<br />Dark energy makes up 73% of the energy in the universe<br />Dark energy is not very dense and isn’t affected by gravity.<br />Very little is known about dark energy<br />
  4. 4. Similarities<br />Obviously they both have “dark” in their names<br />They both can’t be seen<br />There is very little known about both<br />They both make up a big percentage of the universe<br />
  5. 5. Differences<br />Dark matter is obviously matter, while dark energy is energy.<br />Dark energy affects the expansion of the universe, while dark matter affects the rotational speeds of galaxies.<br />They do not interact with eachother<br />
  6. 6. What If We Could Harness The Power Of Dark Matter/Energy?<br />If we could harness the power of dark matter or dark energy, some scientists predict super-human powers and time travel.<br />
