Hi

I am so interesting about time travel. I watched many movies like BACK TO THE FUTURE. Moreover, I read many articles at internet. But I think that because of my English weaknesses or this theory is very difficult, I don't understand about this clearly. So can you explain me?

And then can we have time travel machine one day or is it just imaginary theory?
How do you think?

Thank you

Most people can not understand time travel. Some say if time travel is possible its only possible to go back in time. The key is if time travel back in time is possible you can not change anything because it would mess up a lot to do with the present and that can't be. To understand time travel a little bit I think you have to look at it from outside of time. Some say everything is happening at one time for it to fit into infinity. Sort of like a dvd everything is on the dvd just hasn't been played yet

Time travel is science fiction. There are many theories about it, none proven viable.
