Time is a system used to sequence events and measure durations between events. Space and time are considered to be dimensions that combine to form spacetime according to models in physics. Theoretical methods for time travel include traveling faster than light, using black holes, or passing through wormholes. However, time travel poses paradoxes and challenges such as the grandfather paradox that make it difficult and potentially impossible given our current understanding of physics. More research is still needed to determine if time travel could ever be achieved.

1. Time Beyond Imagination

2. Time Time is a part of the measuring system used to sequence events, to compare the durations of events and the intervals between them, and to quantify rates of change such as the motions of objects.

3. Space-time dimensional and time playing the role of a fourth dimension that is of a different sort from the spatial dimensions. In physics, space-time is any mathematical model that combines space and time into a single continuum. Space-time is usually interpreted with space as being three-

5. Time Travel Time travel is the concept of moving between different points in time like moving between different points in space, either sending objects backwards in time to some moment before the present, or sending objects forward from the present to the future without the need to experience the disturbance in normal rate of time.

6. Experimental Proofs There are various experiments done to check if Time Travel is possible or not. Twin Paradoxial Experiment Is speed of light the maximum speed?

7. Twin Paradoxial Experiment In this Experiment two Cesium atomic clocks were matched and then was kept on earth and other sent in spaceship. After a long time interval it was found that when clock was at higher speed and no gravitational pull was there the clock in ship ran slower than the clock on earth. Therefore, clock on earth was ahead of clock in spaceship.

8. Is speed of light the maximum speed? An Experiment was performed in LHC (Large Hadron Collider) at CERN near Geneva near Franco-Swiss Border. In that Experiment it was found that maximum speed that can be obtained is 0.99999c. It was also found that mass of proton increases 1000 times. And the time for proton decreases 1000 times.

12. Methods For Time Travel Time travel to the past is theoretically allowed using the following methods: Travelling faster than the speed of light The use of black holes Wormholes

13. Time Travel By Train

14. Time Travel By Train In this method, a train track is need that runs around the Earth, has no turn or slight deflections or ups and downs. This train when runs has no speed limit. When it reaches to the speed of light the time travel is possible thereafter.

15. Facts Top speed is speed of light (29,97,92,458 m/sec) Traveling 7 times per second around the Earth. Hence, if the travellers travel for 1 week in train they would have travel 100 Earth years.

16. Limitation: Such a high speed train is not possible. Drawback: It takes the travellers to future only. ie. They can travel only forward in time not backward.

17. Time Travel Using Black Hole

18. Black Hole

20. Black Hole Black hole is a natural time machine. Near black hole time runs slower than away from it. Hence if a person travels around the black hole he would have travel to future when he returns.

22. Facts Radius of the orbital path must 15 million miles ( 15,000,000 miles ). A revolution seems to take 16 minutes to person on Earth. A revolution takes 8 minutes for person the space ship.

23. Limitations: Its too dangerous to escape from a black hole. Drawback: It takes the travellers to future only. ie. They can travel only forward in time not backward.

24. Time Travel Using Wormhole

27. Time Travel Using Wormhole Wormholes are windows between two distinct space and/or time. To time travel one has to just pass through a wormhole. They will travel to different time easily. We can go both in past and future by using Wormhole.

28. Wormholes are very small in size. Diameter is (1 X 10 -15 m). They are need to be enlarged to be able to travel through. Wormholes cant be made. They change the connection frequently. Limitaions

31. You travel to parallel universe You only see and listen not feel anything Or, Time Travel, Not Possible! Possible Solutions

32. The first advantage being that we can travel through time which means we can see centuries in a single life itself. It also means that we can live life with different people at the same time develop technology at its best. Advantages

33. The foremost disadvantage being that time machines when prepared have to be undisturbed as they travel along the earth. Ones we enter into the future we can’t come back past except by the use of a wormholes. Detecting wormholes and making machines which increase their area of tunnels is very difficult . Disadvantages

34. Conclusion We humans need a lot of researches to be done to make time machines. That can either travel faster than light or enlarge a wormhole enough for a man or spaceship to travel through a wormhole. At present time travel is not possible but in future it might be possible to travel in time.
