TIME TRAVEL

OBJECTIVES: Introduction. Einstein’s theory. Fourth dimension. Worm holes. Time machine. Conclusion.

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.

EINSTEIN’S THEORY:

Einstein’s Special theory of relativity says that a surprising thing happens when you move through space-time, 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.

FOURTH DIMENSION: Everything has a width and a height and a

length. But there is another kind of length, a length in time(fourth dimension).

Travelling in time means travelling through this fourth dimension.

WORMHOLE: A wormhole is a theoretical 'tunnel' or

shortcut, predicted by Einstein's theory of relativity, that links two places in space-time

TIME MACHINE:

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.
