2.  What is time ?
 TIME is a 4th dimension in which
we can travel in the same way as we
travel in other 3 dimension

3. ORIGIN OF THE CONCEPT OF THE TIME TRAVEL
1895 – The Time Machine – This is the first story that uses
the phrase time machine.
There is no way of knowing what are the earliest concepts of
time travel but there are many old stories about traveling
forwards in time:

4.  Whenever we think of science fiction, we think
of outer space, black holes, other dimensions
and time travel. But is it proper to classify time
travel as science fiction? Many people would
say yes because they think it is not possible. As
a matter of fact it isn’t possible to time travel
yet. Scientists always look for a way to prove
that something exists or it doesn’t. Time travel
actually cannot be proved or debunked but we
are beginning to see that time travel actually
isn’t as imaginary as we thought it was.

5.  Time travel to the past is theoretically possible
using the following methods:
 Space traveling faster than the speed of light
 The use of cosmic strings and black holes
 Using wormholes

6.  The way to travel in time is to accelerate one end to
the speed of light and leave on end stationary.
Anyone traveling through the stationary end to the
spinning end would travel forwards in time and
backwards in the other way.

7.  Black holes are the end result of supermasive
stars after they go supernova.
 The singularity is small at first but soon it
turn into a giant hole in space which is
known as a black hole.

8.  According to STEPHEN HAWKINGS, time
travel is not like traveling to the past or to the
future.
 It simply means like if it takes 5 hours to go
from position A to B, but somehow we are
traveling that much distance in few
seconds, then it is called as a TIME TRAVEL.
 From the definition of TIME, we know that it
is a 4th dimension, hence we are traveling in
time.

10.  If we were to travel back in time, what would
we do? How many laws of physics and nature
would we break? What would happen if
someone tried to go back in time to kill himself
what happens to his present and the most
important who killed him????
 Is there a way of changing the past without
endangering the future?
B.G.I.E.T. ECE Department

11. From the paradoxes theory
 The universe is conscious and will stop anyone
who tries to change it by making them
disappear on their way to travel through time.
 Any changes to the time stream would
disintegrate the universe itself.
 So we can say that, traveling to the past and
killing himself is not possible for any one as
there will be some logical force of the universe
that will prevent any one every time from
killing himself

12.  Maybe we can travel in time but should we.
Many theories out there state that even if we
could go back in time, we couldn’t change it
because time is prewritten.
 But if it is possible then it may be in the way
suggested by STEPHEN HAWKINGS, by
creating an energy field like
 The scientist are working to create an energy
field like this so that we can do the time travel.

13. A moving clock runs slower than a stationary
clock by a factor ‘ γ ’

14.  Using formulae of time
dilation we can conclude
that if speed is
comparable to speed of
light (c), our age or time
of moving body slows
down by a noticeable
factor

15.  I end this presentation with imaging that in
the coming future we may be able to do the
time travel or in other word we will be able to
travel in the 4th dimension and the most
important what this technology will bring
change in the life of human beings.
