Question

(it is,i have been researching it)

then does that mean there are time traverls upon us?

and if so why havent they told us about the time machines

Answer 1

Why would anyone tell you about the time traveling?  Dont you think that if they are smart enough to travel through time that they are also smart enough not to change their own past?  Just a thought...
