Time travel

Time travel - it sounds good, isn't it? I guess it would be everyone's dream to travel through times. We can travel to future in order to fulfill our anxiety regarding our going-to-be. To know how our universe ends could be full of exploration adventure. Or we could go back to rewrite history. We could have our regrets altered. Wouldn't that be wonderful?

Is it a science fantasy , or could it be really working?

Many great scientists and mathematicians, including Professor Einstein and Stephen Hawking had foreseen the possibility of traveling through times. Professor Hawking did a simple, yet meaningful experiment in testing the theory regarding traveling back to earlier time. He created an invitation for human-being living in the far future to attend a party in the present year (with the exact date, time and venue) written on the invitation card. If time travel works, he would have successfully meet those time travelers from far future attending his party. The clock strikes the exact time the party to be started, but no one turn up. The conclusion is, traveling back through times is mostly impossible.

Before we try to understand why doesn't it work, we have to know how it is supposed to be working first. One of the most popular theory regarding time traveling is through 'wormholes'. Wormholes are extremely tiny, or super microscopic voids that exist in sub-atomic particle. Even if technology evolves in future enabling us to enlarge these microscopic wormholes for objects to enter, it might still not be working. 'Paradox', most likely will occur. Professor Hawking suggested that the resonance and infinity looping of particles traveling between the two-time-worlds across the wormholes will cause it to explode or collapse long before we could even see it forming. A good example will be the sharp-annoying noise from loud speakers when interfere by microphones.

However the good news is, time travel into future is POSSIBLE. Time is not an absolute matter. It is deviated when passing through very dense object. The densest object in the universe? Black holes. If we could fly around black holes without being sucked in into the 'everlasting trap', we could slow our time when flying through it. When you fly long enough, say 10 days around the black hole and return to earth, years could have passed on earth. This, is a one way ticket. You can't go back to earlier time. As black holes are very difficult to locate, and it is almost impossible to be closer enough to black holes without being sucked in, the second solution is travel at very high speed - at speed closer to speed of light. Traveling at light speed, or close to the speed of light could slow our time too.

If one day, the time machine is available, where and when would you love to go and have a look?
