The document discusses the concept of time travel, highlighting its theoretical basis and implications as outlined by Einstein's theory of relativity. It explains that traveling through the fourth dimension allows movement through time, and introduces the idea of wormholes as potential shortcuts in space-time. Ultimately, it concludes that while time travel to the future is theoretically possible, traveling to the past is deemed impossible due to violations of causality.
Time travel
- 2. OBJECTIVES: Introduction. Einstein’s theory. Fourth dimension. Worm holes. Time machine. Conclusion.
- 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: 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.
- 5. 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.
- 6. WORMHOLE: A wormhole is a theoretical 'tunnel' or shortcut, predicted by Einstein's theory of relativity, that links two places in space-time
- 8. 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.
