People have often thought of going back in time because of regrets or mistakes they want to fix in the past. The only way to go to the past is time travel there. Time travel has been know as science fiction but now scientist have been believing time travel is possible based on the physics laws. If time travel is possible, then will it be helpful for human begins to go back to the past. Time travel can’t be worth it because if you change something in the past, it will affect a lot in your future. The people you thought you knew may not be the same people in the future because you change something in the past. There are different theories stating on that there may be parallel universe and other versions of us.
There are philosophical views about nature of time in time travel if it is possible. One view is called eternalism which means the beliefs of past, present and future already exist. Eternalism is description of space time as an unchanging four dimensional block. Another philosophical view of nature of time is presentism which means there is a past but the future isn’t set yet. As passes the present becomes as the past and the future as the new present. This means that time is moving forward into the future and leaving the past behind.
Scientist has come to a conclusion that time travel could be possible because of the new modern physics laws. One theory is that wormholes are a short passage through space-time for long journeys. In 1935, Albert Einstein and Nathan Rosen came up the theory of general relatively in which they discover the bridges or wormholes through space-time. In an article, it says, “A wormhole would allow a ship, for instance, to travel from one point to another faster than the speed of light — sort of. That's because the ship would arrive at its destination sooner than a beam of light would, by taking a shortcut through space-time via the wormhole,” (Sharr, “What is a wormhole?”). The wormhole has two mouths and a stretch out throat which people believe to think it is a fast way to time travel. Even though Albert Einstein created this theory, wormholes haven’t yet been discovered. Scientists have hope that modern technology will help them discover wormholes and explore them.
