Wormhole-how to make and travell through

Hey guys,
Are you not intrested in time travell. Do you not want to go back or forth in time? Every one wants that but, still we are unable to do that because it can only be done by travelling through a wormhole.
So, that is what I want to know. Can we make a wormhole and if yes how can we make it because there are some things I want them to change in my past.

Thats interesting how to make a wormhole. I don't know how to make it. If you get any information how to make it and how to travel through then share it with us.
