> picture this: we are interlinked with everything around us, or rather, we are all embroidery on one cosmic tapestry; every air molecule, every photon, every ant on the ground

> THEREFORE travelling through time would equate to travelling to that particular state of the universe, and you would resume the state you were in at that time. we cannot bring our memories backward because there are no elements in that state, that frame, that "snapshot" for those memories
> those memories did not exist at that time and therefore cannot, lest something else become non-existent

oh, add whichever blows may come to mind, but there is no protection from mankind.
