Time travel (journey beyond time)

Journey beyond

‘TIME’

Theory of GENERAL RELATIVITY1. 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

Space Time

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.

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.

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.

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

Mediums of TIME TRAVEL

Cosmic Strings

Cosmic Strings

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

Wormhole

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

Stephen Hawking’s Idea

Hawking’s Train

The train will travel at speed of light and the time inside the train slows down or dilates.

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
