President on worst case scenario

           The worst case scenario to a time machine would be a black hole that would slowly consume the world till nothing is left.  I we were to find a way to time travel we would be affecting the space time continuum causing a black hole to form the only way to stop it from killing off every human being on the planet would be to find someway to get human beings up into space and able to stay there until we could find another planet to live on. The hole would consume anything and everything including light. A black hole has no passage of time and no end so while you might not die from being sucked in you would probably die from lack of oxygen but the worst would be being crushed into nothingness.
