Lets travel through time

1. Journey beyond
‘TIME’

3. Theory of GENERAL RELATIVITY
1. Equivalence Principal:Inertial Mass
and Gravitational Mass are the same
thing.
2. Light always follows
Geodesics.(Geodesics are the shortest
path between any two points on any
surface.
3. Locally SPACETIME IS flat.
4. Universally SPACETIME is curved by
massive objects

4. Space Time

5. Theory of SPECIAL RELATIVITY
1. Space and time form 4-D Continuum.
2. The laws of physics are the same in
any inertial frame, regardless of
position or velocity.
3. The speed of light c is a universal
constant, the same in any inertial
frame.

6. TIME DILATION
 In Special relativity, clocks that are
moving run slower, according to a
stationary observer's clock.
 In General relativity, clocks that
are near to a strong gravitational
field (such as a planet) run slower.

7. Length Contraction
One of the simple aspects of Einstein's
theory of special relativity is that the
length of objects moving at a very high
velocity undergoes a contraction along
the dimension of motion.

8. Length Contraction
When velocity is 25% of light When velocity is 50% of light
When velocity is 75% of light When velocity is nearly equal to light

9. Mediums of
TIME TRAVEL
Cosmic
Strings
Wormholes
Hawking’s
Train
Alcubierre
Drive

10. Cosmic Strings
Cosmic Strings are 1-dimensional (spatially)
topological defect in the fabric of spacetime left
over from the formation of the universe

11. Wormhole
A wormhole is a theoretical connection between a blackhole and
a white hole creating a shortcut through time and space.

12. Stephen Hawking’s Idea

13. Hawking’s Train
The train will travel at speed of light and the time inside the
train slows down or dilates.

14. Alcubierre Drive
An Alcubierre Warp Drive stretches spacetime in a wave causing the fabric of
space ahead of a spacecraft to contract and the space behind it to expand. The
ship can ride the wave to accelerate to high speeds and time travel
