On Time but not for timepass

What an experience it would be to have a time machine! Just imagine traveling into the future, seeing technological marvels that have yet to be invented, and meeting our distant descendants. What will the world be like in 500 years? Or 100?
Science fiction abounds with time-travel stories. This perhaps reveals a fundamental aspect of human nature: We are fascinated with time! aren't you huh?
I believe We have a sense of eternity that God has placed in our hearts, so it’s not surprising that adventures through time captivate our imaginations. But is time travel really possible?
Okay, we must understand that real time travel is far more limited than the unrestrained freedom enjoyed by characters of science fiction.
First, it is limited in direction. It seems that time travel into the future is permitted, whereas time travel into the past is not. In principle, it’s possible to send a person forward 100 years or more to see his distant descendants. However, he could not come back.
Second, time travel into the future is limited in degree by our current technological level. While it is theoretically possible to send a human into the distant future by traveling close to the speed of light, such speeds are far beyond the limits of our current technology. The velocity necessary for noticeable time travel requires energy that drastically exceeds what we can currently produce.
There is also the paradox of the man with no past. For example, let’s say that a young inventor is trying futilely to build a time machine in his garage. Suddenly, an elderly man appears from nowhere and gives the youth the secret of building a time machine. The young man then becomes enormously rich playing the stock market, race tracks, and sporting events because he knows the future. Then, as an old man, he decides to make his final trip back to the past and give the secret of time travel to his youthful self. Question: where did the idea of the time machine come from?
However, before Einstein died, he was faced with an embarrassing problem. Einstein’s neighbor at Princeton, Kurt Goedel, perhaps the greatest mathematical logician of the past 500 years, found a new solution to Einstein’s own equations which allowed for time travel! The “river of time” now had whirlpools in which time could wrap itself into a circle. Goedel’s solution was quite ingenious: it postulated a universe filled with a rotating fluid. Anyone walking along the direction of rotation would find themselves back at the starting point, but backwards in time!
In his memoirs, Einstein wrote that he was disturbed that his equations contained solutions that allowed for time travel. But he finally concluded: the universe does not rotate, it ex- pands (i.e. as in the Big Bang theory) and hence Goedel’s solution could be thrown out for “physical reasons.” (Apparently, if the Big Bang was rotating, then time travel would be possible throughout the universe!)

haha.....well............(time stop)
Interestingly enough, Stephen Hawking once opposed the idea of time travel. He even claimed he had “empirical” evidence against it. If time travel existed, he said, then we would have been visited by tourists from the future. Since we see no tourists from the future, ergo: time travel is not possible. Because of the enormous amount of work done by theoretical physicists within the last 5 years or so, Hawking has since changed his mind, and now believes that time travel is possible (although not necessarily practical). (Furthermore, perhaps we are simply not very interesting to these tourists from the future. Anyone who can harness the power of a star would consider us to be very primitive. Imagine your friends coming across an ant hill. Would they bend down to the ants and give them trinkets, books, medicine, and power? Or would some of your friends have the strange urge to step on a few of them?)
Although we cannot travel back in time, God knew that we would be curious about the past, how the universe came to be, and where it is headed. So He graciously gave us His written Word, providing us the most important details of history and glimpses of the future as well. In this respect, the Bible is much like a time machine. When we read God’s Word we are virtually transported to another time. We experience history in light of God’s plan of redemption. And the Bible even gives us a taste of the wondrous eternal state to come. We see how all of time—past, present, and future—is under God’s sovereign control.
In conclusion, don’t turn someone away who knocks at your door one day and claims to be your future great-great-great grandchild. They may be right.
