the bomb that could change the world

The article that i read was all about how nuclear blasts can change the earths orbit.I got the article off of the live science website and it was all talking about if it can or not.when there is a nuclear explosion, they only change the orbit by a trillionth of our orbital energy.it eas also saying that other natural causes like tsunamies and earthquakes do the same thing to the earth but none of them put if off track.i think in the future, if we still use nuclear bombs, will not alter the earth.
