spicing things up, what do u guys think about time reversal/acceleration?

in time travelling, individual a will go to the past and he can see his past-self.
but in time reversal, its like rewinding things.

most of the time paradox wont apply here because when u reverse time, u actually erase the present time. theres nothing to paradox with as u need the past and the present/future to achieve a paradox. u still get the chance the chance to rewrote the past-present.
but i do think time reversal would cost too much energy to be done anyway. imagine u unraveling every builded things, reversing every physics phenomenon.
a simpler view would be EVERYONE is time traveling.
the future, AGAIN, could be anything as phenomenon that relies on randomness may yield different results.
and i dont think u can attain the knowledge uve gained all of those years, right?

i doubt it. rite now, most of developed country r more concerned on energy research.

means ur a goner
