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. 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. 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. LOCATING 4D
SPACE TIME FABRIC
 In physics, spacetime is any mathematical
model that combines spaceand time into a single
interwoven favbric.

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. •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. 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. 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.

11. THE LARGE HADRON COLLIDER (RESULTS)

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.
