Hello Many people heard about aproaches for time machines. Particularly I'd like to discuss Stephen Hawking's thought, that a time machine is impossible because otherwise we would have tourists from the future, unless we can't go back to time before a time machine was made. I think everyone took this idea under attention, but I'd like to discuss it aloud. What if there is no tourists from the future because there is no defined future ahead of us? Maybe We are the past, present and the future, not anyone else. Our acts and deeds define and make future, not defined future causes us to do something. Time machine is definitely passible and we can go back to what ever time we want, but first we have to build it, it's not built somewhere far in the future. What do you think about it?
