According to the dictionary, Time travel is the concept of moving between different points in time in a manner analogous to moving between different points in space. It has been a controversial question for more three hundred years. Is it possible to have a time travel?
In my opinion I strongly believe that time travel is possible. According to the video we watched during the class, human is already able to do a time travel in several ways theoretically. For example, as we discovered, time travels slower as the object moves faster. Therefore, as the speed approaches to the light speed which is around 300,000km/s, time will be closer to zero and finally stops. If we accelerate the object over the speed of light, the time will be negative and the object travels back in time.
Also, we also may travel to the future or the past by getting into the wormhole, but it is so complicated and hardly practical. But I believe one day, with the development of the science and technology, the time travel will be possible eventually.
