Timewarp stories

I've been reading one of the books Nathan gave me..
it's a collection of stories where time is important..
I'm thinking about what would happen if you messed with time..
the consequences could be very disastrous..
go read A Sound of Thunder by Ray Bradbury..
one dinosaur hunter accidentally steps on a butterfly..
upon returning to the future, it's been irrevocably altered..

if we go back in time and try to change history..
it could have impact through the spinning years of time..
imagine killing one insect; birds, prey, man are affected..
one simple act has unforeseen consequences..
conclusion: don't try to mess with time!

(though a time machine would've helped the last two weeks)
