Top 3 apocalypses - part I

I was talking yesterday about the possible End of Days in 2012, but let's have a look at the most realistic threats to human civilization. In my opinion there are 3 major catastrophes that may occur and modify forever this world we're living in.
My first catastrophic event is an asteroid hitting the Earth, event that nowdays is so vehiculated regarding the extinction of the dinosaurs. Of all the 3 events I've chosen for a probable Apocalypse this is the one with the smallest chances of hapenning. After all, each human has more chances of winning the big pot at the lottery 3 times in a life than a big asteroid destroying our planet.

We are hit every day by hundreds of small cosmic rocks, but 99,99% burn entirely in the atmosphere and only a few reach the Earth surface where can be collected and studied. We can even see "rains of stars" when the Earth is bombarded by thousands of asteroids showing a true magical show.
However this is the bright side, as the Earth was and surely will be struck by bigger asteroids that not only do they pass our safety measures identified by the atmosphere, but also they manage to hit the surface with devastating force that can have fierce effects. Last century, in 1908, a huge explosion devasted a huge surface of Siberian woods, with the equivalent of 1 000 Hiroshima atomic bomb. This event shows how real and close to us is this danger and only the luck made that asteroid hit a unhabitated area.

Probably that's why the big economical powers of the world have decided to invest some serious money in developing a global defence programme that uses many satelittes and observatories all around the world. Thier main goal is to identify any possible threat to the Earth and to do in time to let the humanity prepar for the worst.

2012 – the end of our civilization?

If you still haven’t seen this year’s movie 2012 – the Apocalipse, then you probably will after reading my article. I won’t comment about the scenario or about how the actors played in this movie, but I will try to comment a bit on the idea that stands behind this movie creation.

Everythins starts for the Maya calendar, which suddenly ends on the date 21 December 2012. Why, no one knows for sure. Maybe they knew something hundreds of years ago and left this this calendar as a prophecy. Or maybe they ran out of time writing on the wall with the Spanish conquerers on their trails. Or maybe they thought time has an end, like the other scholars of their time thought the Earth is rectangular and at his sides you will fall off in never ending abiss.
The interesting part is that most people took this seriously and like in 1999, 2000, 2009 now the next deadline given to the humanity is 3 days before 2012 Christmas day.
This movie concept is somehow based on this idea and on some huge Solar explosions that release an huge amount of neutrons that make out planet’s core act like a giant nuclear plant. Which follows is somehow hilarious, as before any crust melting or colapssing in the Earth’s lava mantle all oceans will be long gone boiled and evaporated.
Well I’m not going to spoil all your fun watching this apocalipting movie, but the science fiction scenario can only make you look with confidence to the future.
However there are some real threats that can end the existance of humans, even before 2012. But about this I will write in a future post so stay close.
