Chronohistorian (the sad lonely kid, you know him): you state that forward movement in time is impossible. As I find this hilarious, I would like to point out the following:
Look at your watch or the time display on your computer. Finish reading this post and look at the clock again. Note measured passing of traditionally-defined time. Further note that you have travelled forward in time at the rate of roughly one second per second.
Having travelled "back in time", you are now "in your own past". By your own statement, you are now trapped here forever. Although all is not lost -- you are in fact approaching the "future" second by second.
With respect to time travel, does not the fact of time travel make the term "future" redundant at best? How can there be a "future" when you are no longer trapped at the knife edge of history but can range through spacetime at will?
And on a related note, please stop talking about "chronoradiation". Gibberish is one thing, but gibberish about more or less settled concepts in science like the meaning of the word radiation is something else again. Radiation does not affect time, unless you get a really big dose of it, in which case your own time is affected pretty drastically - you run completely out of it and die of leukaemia.
