If I had a time machine.... I would go to the Past and resolve conflicts, wars and problem. I would go to the 19th century and 20th century and clarify the problems between British and India. I would make sure that there were no World Wars.I would make sure there were no conflicts between countries. I would go to the Stone Age and observe how things were and how humans of the Stone Age communicated. I would also make a visit to the Future and see how technology of the future works.
