LLOOOLLL ... total crazy ... but, good arguments ....
but if you have changed something in your past, this will effect your future aswell , so WHERE can you return once your job is done ?
this would apply aswell to the question you made ... even if another person visits you he would change something ...
hm, buy hey , would that mean that your future-you wouldn't have "fatamorgana" laters in the future, lol ? cuz he would see the same person in da past and then the same person laterz ... and what if you were really good with that future-him who went to the past band you know everythign about him .. but them 50 years laters (lets say this future-he already went to some deepshit hole somewhere in other dimension or whatever ) you meet the same person you met in the past, but he doesnt know who or what you are ... this way he would confuse you, you wuld even more confuse him, and maybe after all this he wouldnt use tat time machine again cuz he would to go the hospital cuz of some serious brain damage
what we have now is next: someone was able to use the time-machine once, but he was stopped in the future for making the same mistake (?) again ...
hm ... but what IF :
someone would have the time-machine and the cloaking device which would prevent that other (me, me, she .. whoever) sees him and by that way he maybe would change the current psycho status from other people ... ?
