Time travel through black hole

Well what a black hole means.No one can properly tell what a black hole is? but it is consider as a heavenly body having infinite density and gravity from which the light also cant escape.what a time travels indicate then it indicates the movement of us in according to the time that is we can move to the past or future.It is the burning curiosity of the today's world on how do we move according to the time so the main focus here is we all may know that the time moves slow when the gravity is high, higher the gravity less is the time taken to make one rotation. So different planets have different times. In one place there is high gravity while in other place there is less gravity that affects the time period hugely.this is the region for the difference in time between different planets.
       
        It is also said that time in the near area of pyramid is also slow.Lets us consider a huge body of infinite gravity which is also called as black hole that has infinite gravity then how could we travel to it. Actually we are not going to travel to its centre but we are trying to travel to its outer orbit to where it has minor effect of gravity. From here we can launch a space ship which is very powerful and could overcome the minor effect of gravity. From rounding around the black holes orbit a person inside the space ship could feel that he is time travelling. In this way we can time travel through the black hole.

        But the nearest black hole is very far. The light takes 1600 years to reach to that place by its speed. we know that nothing could exceed the speed of light then how could we go there the first question rises that has no answer, and though it is considered true for the time travelled there are many limitations which need to be fulfilled and the next is the black hole is a huge mass and that having a huge diameter to where the spaceships takes much more time and finally there is a very high risk if that body reaches to the centre of the black hole. Then the body will never returns back so if the science of future find all these answers then to that time there we can have the time travel but till this time it is only in theory to time travel through black hole.

         Hence though the time travel is not possible through black hole but we can travel through "Worm hole" which the scientist have claimed to have existence in our universe this holes are the point that joins the portion of the universe i.e it joins the two points of time so if we can know about this hole then we can know about the time travel and the scientist are also searching  about this.

           The Hawking's theory has defined the time travel by the train to move round and round the earth it gives the explanation about the time difference or time dilation according to the light of speed but it is only in hypothesis as i have already mentioned that nothing could move with the speed of light.so this portion or idea of time travel is also do not work.
