Spacetime is a whole bunch of stuff. I hate to harp on about things we all know, but if we did meddle in our own history, even the history of our planet, would it matter a jot in cosmic terms? Seriously, I doubt it. Some say "There must be safeguards", but whom will these safeguards protect? A bunch of carbon-based organisms whose time on this planet and contribution to the Universal All is as important as the next word I type.
