Time Machine

Our universe is huge compare to the earth we live in. When we traveling around in the universe, our transportation is too slow to do that. It takes 4 years for light to travel to the nearest star from earth. To visit another star, we need a faster way do not take that much amount of time. Like time machine, wormhole gives us a chance of travel in universe in a short time for a long journey.





Figure A (How does wormhole works)




Figure A, is a model of wormhole shows how does wormhole make teleportation possible. As human, we can only see up to three dimension world, but this model visualize the function of wormhole. Wormhole is one dimension higher than our three dimension world, just as three dimension world to two dimension world. Assuming our universe is a two dimension world on a sheet of paper, it will be really hard for us travel from right side of paper to left side of paper. However, after folded the paper, the right side of paper is adjoin the left side of paper. The blue part as shown in Figure A, join both side of universe together is called wormhole."Manipulating space in this way means you can jump into one end of a wormhole, travel a short distance, and pop out from the other end in another galaxy." However, the wormhole might causes a timetwist, and we cannot predict which way the time twist. After pop out from wormhole, the person might either goes to the future or the past. Furthermore, the other end of the wormhole might toward an other parallel universe.




In 1935, Albert Einstein and Nathan Rosen proposed that there is a existence of wormhole by using theory of general relativity. To make a wormhole require the "insertion of something that anti-gravitates", which is called negative energy as shown in Figure B. However, for current science technology development, it is impossible for us get enough negative energy repels each other and keep the wormhole open. Hence, we look forward to find a matter have a huge negative energy that can help to build wormhole.
