Time Travel

Have you ever wished if only you could travel back in time and do something different? Or maybe travel into the future and see how your life would be 20 years from now? There have been many science-fiction movies that revolved around time traveling, for example The Time Traveler's Wife. With all the technology advances, one would think that by now there would be a time machine that would allow time travel.

An article from Clifford Pickover, Traveling Through Time, mentions that time travel is possible. He gives an example explaining that if one was to "travel into outer space and return, moving close to the speed of light, you could travel thousands of years into the Earth's future." But that theory only indicates the possibility of traveling into the future, not into the past. Physicists admit that traveling to the past will not be easily attainable. 


The Star, an online news site, published an article in which scientists rejected any possibility of time travel. Shengwang Du, an assistant professor of physics who studies quantum optics and the interaction between photons and atoms, suggested that "time travel based on photons or optical methods is impossible, but we cannot rule out other possibilities for time travel, such as wormhole and black holes in general relativity." 


Time travel into the past may not ever be possible, or not even into the future, but there will always be moments when I wish it was.
