If I Could Go Back and Change the Past?

      Time travel is the most mysterious and creepy and fictional things in our life.  It is the imagination of humans to travel to their past and to correct their mistakes and to the future to see the future and due to high curiosity.  we have reached a high level of intelligence it uses a device which is called time machine to travel in the space but it is not just an imagination it is known to everyone and it has both fiction and philosophical content.  The time machine was imagined by H.G.Wells in 1895's novel the time machine it is said in the quantum physics and degree of relativity to possibly travel back in time.  If we can slow down the time but according to Einstein-Rogers theory we could possibly do time travel if we can travel and survive in the wormhole or on the surface of a blackhole.  we could travel but it is merely imagination and practice.  It is impossible because to travel in a black hole and survive is impossible because nothing could survive from the gravity of the black hole.  Through the blackhole, there is a wormhole which creates a different dimension of the universe from the observable universe. Moreover here are accepted method of doing time travel likes if we are able to create such a vehicle which would take us nearer to the speed of light or almost at the speed of light then it is possible to travel into the future because as said in quantum physics an object that travels in the speed of light becomes light.  So the speed is nearly whopping 299,492 km/s that is fascinating speed and this speed is enough to reach our nearest planet Mars in 3.9s and if we give few more seconds we will be able to travel to Pluto, Saturn and even to the things in our galaxy which is unobservable.  It will be very far for us through to reach the nearest Andromeda galaxy through if we even travel in the speed of light.  Time travel is possible is we can revolve around the black hole because time slows down in the black hole.  

     If we create a vehicle which can travel nearer to the speed of light and if do so then we will be able to travel in the future and if we create a machine which may go in the past or future.  We can do time travel it is estimated in around 2030 time travel will be done as said by Noah, the time traveler.  It can also be done by slowing up or speeding up the time like if we go and able to survive in some planets like Acheron UB-26B13 the year will be completed in one day in that planet because it completes its revolution on its axis.
