Time travel is possible, according to mathematical models and scientific theories. However, the current status of science and technology does not allow us to build a device that can travel back in time. It is believed that in the distant future, time travel might be possible through advances in technology.
Physicists are researching to find answers to a few unknown questions. One of the questions that they are researching is related to the possibility of time travel. They want to find out whether time travel is possible. If somehow possible, a time machine can be created. This is the reason they are researching and working on it. The search for the time machine is on!
