Time Travel

  1. 1. Muhammad Zaroon L1f12bsme0059 PRESENTATION : TIME TRAVELL
  2. 2. CONTENT  Introduction.  Einstein’s theory.  Fourth dimension.  BLACK holes /Worm holes.  CERN lab Results  Conclusion.
  3. 3. INTRODUCTION  Time travel is the concept of moving between different points in time in a manner analogous to moving between different points in space, generally using a theoretical invention, namely a time machine.
  4. 4. EINSTEIN’S THEORY a surprising thing happens when you move through space-time (4D), especially when your speed relative to other objects is close to the speed of light. Time goes slower for you than for the people you left behind. You won't notice this effect until you return to those stationary people.
  5. 5. FOURTH DIMENSION  The things in our daily life have height, width and length.  Assumption of 10 dimesnion  Travelling in time means travelling through this fourth dimension.
  6. 6. LOCATING 4D SPACE TIME FABRIC  In physics, spacetime is any mathematical model that combines spaceand time into a single interwoven favbric.
  7. 7. WHAT TRAVELER NEED ???  A black Hole / White Hole A black hole is a huge mass packed in a very small It is a place in space which has such a big gravitational field, that nothing, not even light can escape.
  8. 8. •traveler have to enter a rotating black hole •avoid the singularity travel into a rotating white hole •allows the traveler to escape into another universe.
  9. 9. WORMHOLE: A wormhole is a theoretical 'tunnel' or shortcut, predicted by Einstein's theory of relativity, that links two places in space-time ‘Combination of Black and White Hole ‘
  10. 10. RESULTS FROM RELATIVISTIC EQUATIONS •Time and distance are relative to each other. •Approaching speed of light the distance become shortened and while time becomes lengthened. •For a person travelling at 99% of velocity of light, time slows by 7 factor. 1 year is equivalent to 7 years for observer from earth. •For 99.999% its about 230 years •For a velocity of light the time factor becomes zero •When it crosses the velocity of light the time becomes reduced and runs in reverse time factor.
  12. 12. CONCLUSION:  We can go into the future. Time travel to the future is possible under Albert Einstein’s general theory of relativity.  But time travel to the past is impossible. Because it violates the law of causality, or cause and effect.
