Dark matter and dark energy

  1. 1. Dark Matter and Dark Energy revolutionary concepts in cosmology
  2. 2. Construction of universe 73% Dark Energy 23% Dark Matter 4% Atoms <ul><li>The universe is not constructed of Atoms only. </li></ul>
  3. 3. What is Dark Matter <ul><li>It is a type of matter that </li></ul><ul><ul><ul><li>Isn't formed by atoms. </li></ul></ul></ul><ul><ul><ul><li>Doesn't absorb or emit light. </li></ul></ul></ul><ul><ul><ul><li>Has same gravitational properties </li></ul></ul></ul><ul><ul><ul><li>as ordinary matter. </li></ul></ul></ul><ul><ul><ul><li>Binds the universe together. </li></ul></ul></ul>
  4. 4. Construction of Dark Matter <ul><li>Dark matter is constructed of a supposed partical known as neutrolino. </li></ul><ul><li>It is yet to </li></ul><ul><li>be discovered. </li></ul>
  5. 5. Detection of Dark Matter distortion due to gravitational lensing.
  6. 6. Role of Dark Matter <ul><li>The force of gravity is inversely proportional to square of the distance between the objects. </li></ul>
  7. 7. Role of Dark Matter <ul><li>Dark matter binds the stars and planets within a galaxy through its gravitaional </li></ul><ul><li>effects. </li></ul><ul><li>It holds the galaxies in the form </li></ul><ul><li>of constellations. </li></ul>
  8. 8. What is Dark Energy? <ul><li>The dark energy </li></ul><ul><ul><ul><li>is non-particulate </li></ul></ul></ul><ul><ul><ul><li>has repulsive gravity </li></ul></ul></ul><ul><ul><ul><li>is a force that drives apart the universe </li></ul></ul></ul>
  9. 9. Construction of Dark Energy <ul><li>It is practically non-particulate. </li></ul><ul><li>In Quantum Mechanics it is thought to be constructed of a combination of a sub-atomic partical and it's anti-particle. </li></ul><ul><li>e.g. when neutrino and anti-neutrino </li></ul><ul><li>combine, dark energy is </li></ul><ul><li> formed. </li></ul>
  10. 10. Role of Dark Energy The universe is expanding. Actual continuity theory Gravitational field theory
  11. 11. Dark Matter vs Dark Energy <ul><li>Dark matter is formed of particles. </li></ul><ul><li>It has attractive gravity. </li></ul><ul><li>It binds the universe. </li></ul><ul><li>Dark energy is non-particulate. </li></ul><ul><li>It has repulsive gravity. </li></ul><ul><li>It tears the universe. </li></ul>
  12. 12. Fate of the Universe
