Well, if you believe the multiverse theory where reality is constantly fracturing endlessly into infinite different universes based on this or that events..... then if you were to send so much as a single electron back in time, that enough of your other versions on closely parallel tracks would have done the same.. when all these electrons converged at the same place at the same time it would be enough mass to collapse the entire multiverse into a singularity...
