no one can ever travel in time duh...
only in fiction movies or novels..
it is told..you can nver reach the past...

even if a theory can says that travel in light speed can do it...but..there is no machine can travel in the speed of light....

besides it is only a dream....
i am sure that everyone wants to go to the past or future to change something for their own needs...
but unfortunately..time travel is not theoretically and practically proved...

so..dont ever dreamed to time travel...
tq..
