No, as far as anyone knows.





In World War II, during the Manhattan Project, the scientists who were building the first A-bomb were now sure how far their predictive math was valid, and they were not sure that the entire Earth, or a significant part of it, wouldn't just unravel when they did the first test. It didn't.





The first a-bombs were measured in ';kilotons';, meaning the equivalent explosive power to thousands of tons of TNT. Since then, bombs have been constructed, and tested, with the explosive power of ';megatons';, or millions of tons of TNT. These bombs have been tested on the ground, above the ground, and underground, and the Earth hasn't unraveled.





Of course, the big problems with nuclear weapons are:


Radiation that lasts for years, tens of years, or hundreds of years


The tremendous amount of heat generated, which could kill more than the explosion does


The amount of ';bang'; for a small package, which means that it doesn't take a lot of resources to deliver a bomb somewhere.





For a funny but scary movie on the idea of nuclear war, see ';Dr. Strangelove, or how I learned to stop worrying and love the bomb';.





For a really scary version of the same thing, read, or see ';Fail Safe';.

Unfortunately this device does exist. The United States, Russia and possibly China process this weapon. It is a cobalt salted device with a nuclear throw weight of approximately 50,000 megatons. To put this in perspective, the most plentiful average nuclear weapon is 1 megaton, which is 50 times more powerful than the weapons used in the 2nd world war on Hiroshima and Nagasaki. It is commonly referred to as the ';Doomsday device';. I believe it would destroy our planet. I'm sure this makes our Creator very proud. NOT!
No......it is thought though that Israel has nuclear weapons, but that has never been confirmed.
Of course the GREAT USA. Who else can dare....
