The Paradox of Popping Back in Time

• arclein

Things very quickly get very brain boggling. Consider this ?" if someone builds a time machine what's to prevent them going back one minute and smashing it up before they first use it? Which means it never gets used ?" so how did it get smashed up. What prevents the whole parade of paradoxes thrown up by time travel to the past ?" becoming your own grandfather, killing Hitler before he starts World War Two and so on ?" is that they trash big laws of physics. And the Universe, as far as we understand it, likes to play by the rules.
