Chances are, nothing will happen. And in the case something actually happens, it's not like there'd be anyone left to complain about it
As an example of how science hasn't managed to kill us all despite of all her efforts, when they detonated the first atomic bomb, they weren't sure on wether it would cause a massive chain reaction that would make all the air in the world explode. And as far as I know, it only turned out to be the most powerful and deadly device ever created by man. So I wouldn't worry about it. Though it won't hurt if you start working on getting to heaven. Just a friendly advice.
