Origin of the Hatch and the Failsafe Switch.

After the last 2 episodes, I’ve come to believe that the hatch served 2 purposes. 1: to reset the island in the past 108 minutes at a time (from theories on other sites). 2: to serve as the place to bury the leaky atomic bomb. The Hatch is located on a very special spot on the island where electromagnetism is concentrated. This location was picked for not only that reason, but it was probably the perfect place to contain the unstable atomic bomb Faraday suggested to bury using lots of concrete. Remember in season 2 when Sayid and Jack investigate the pipes under the hatch and they came across a massive amount of concrete? Could this be where the leaking atomic bomb was buried? Remember, Sayid said “the last time this much concrete was poured…Chernobl”. Once this bomb had been buried, it’s radiation was further contained by the magnetic properties of the site. This brought me to a second conclusion regarding the ‘failsafe’ switch Desmond turned.

The failsafe was actually the trigger to the atomic bomb. When Desmond turned the key, the Hatch was blown to smithereens, but the blast was contained by the magnetism, resulting in the sky turning a weird color (probably from the release of the radiation/magnetism) and Desmond’s clothes missing because they were burned off. The reason Desmond didn’t die (nor did anyone else) is because the island protected him (see my theory on Richard Alpert about immortilization by the island).
