北は南、南は北。

Saw discovery channel on tue while havin my dinner. OMG, do u know that the earth's magnetic polarity switches every few hundred thousand years??? that means that north becomes south! imagine the hell that will happen! and according to studies, we are currently overdue for a polarity switch!

The documentary also said that during the phase where the north is becoming south (few thousand years), the magnetic shield that protects us from the solar radiation will go haywire, and we'll be exposed to the dangerous rays up to 20 times stronger than wat it is now. that means more ppl (and watever living creature) dying of skin cancer. gosh.

However, on a lighter note, the documentary did end by saying that "at least we get to see auroras in the sky everynite from anywhere in the world when that happens." Yippee.
