Time travel

  1. 1. Time Travel<br />By<br />Ankush M. Tayade<br />Stud's Of Electronics & Telecommunication<br />DES’s COET Dhamangaon Rly.<br />
  2. 2. This ppt Is Dedicated<br />To Nature<br />
  3. 3.
  4. 4. Afraid of the Dark?<br />Who remembers trying to race against light so you could get in bed before it got dark?<br />Turned out light was really fast<br />If only we had a time machine<br />Note: All The concept On that ppt are concesion to NASA & Stefan Hawking Theory <br />
  5. 5. Einstein’s Great Idea<br /><ul><li>The speed of light is constant(ly very fast)
  6. 6. If we had very fast spaceships, this would allow us to observe some crazy things
  7. 7. For example
  8. 8. The twin paradox
  9. 9. But we don’t need a spaceship
  10. 10. A regular passenger jet will do
  11. 11. Or even just a tower!</li></ul>Note: All The concept On that ppt are concesion to NASA & Stefan Hawking Theory <br />
  12. 12. Backwards Time Travel<br /><ul><li>Going forward in time is (relatively) easy
  13. 13. Going back is much harder
  14. 14. But Einstein’s theory of general relativity seems to allow it
  15. 15. It depends just how much space-time can curve</li></ul>Note: All The concept On that ppt are concesion to NASA & Stefan Hawking Theory <br />
  16. 16. What is Time Travel Again?<br /><ul><li>Actually going to the future or past
  17. 17. Not just some replica of it
  18. 18. It’s all relative
  19. 19. For me to time travel, there would need to be a difference between the speed time passes for me and the speed time passes for someone or everyone else </li></ul>Note: All The concept On that ppt are concesion to NASA & Stefan Hawking Theory <br />
  20. 20. Time Travel in Future<br /><ul><li>It is possible to travel in time ?</li></ul> * Yes<br /> * No<br />Yes, it is possible but there is big IF<br />Note: All The concept On that ppt are concesion to NASA & Stefan Hawking Theory <br />
  21. 21. The Fourth Dimension <br /><ul><li>What is fourth Dimension ?
  22. 22. 1-Width
  23. 23. 2-Height
  24. 24. 3-Length
  25. 25. 4-</li></ul>Time<br />Example<br />The laws of physics actually accommodate the notion of time travel, through portals<br />known as wormholes.<br />Note: All The concept On that ppt are concesion to NASA & Stefan Hawking Theory <br />
  26. 26. Special Relativity<br />* If we could Travel faster than light ,One could also go Back in time<br />Note: All The concept On that ppt are concesion to NASA & Stefan Hawking Theory <br />
  27. 27. V<br />Thanks'<br />
  28. 28. Time Travel is Possible!!!<br /><ul><li>This might be a hoax, but time travel really is possible
  29. 29. In fact, many of us have already done it</li></li></ul><li>What is Time Travel Again?<br /><ul><li>Actually going to the future or past
  30. 30. Not just some replica of it
  31. 31. It’s all relative
  32. 32. For me to time travel, there would need to be a difference between the speed time passes for me and the speed time passes for someone or everyone else </li></li></ul><li>The ‘No Destination’ Objection<br /><ul><li>If you haven’t thought through all of the implications of 4-D space-time, then you may still believe:
  33. 33. That the past no longer exists
  34. 34. That the future doesn’t exist yet
  35. 35. That only the present time exists
  36. 36. If these points are true, then time travel is impossible because there is no other time to travel to</li></li></ul><li>Time Travel is Possible!!!<br /><ul><li>John Titor came from the </li></ul> future… and provided truth <br /><ul><li>This might be a hoax, but is backwards time travel really possible?
  37. 37. Physicists say that it is… but what about the logical contradictions that would result?</li>
