My Earth Day Tribute.

I haven't really seen any documentaries on History, Science and Discovery Channel. Monday night, as we were looking through the guide Italiano saw a documentary on History Channel called Last Days on Earth.

This documentary is about seven catastrophic scenarios that earth may encounter and end humans existence. The possibilities of these events was discussed from least likely and to the most possible to happen. Who says you can't learn from watching TV right. The thing I like the most about documentaries would be the illustration and the graphics they have amazingly put together. Not only do you learn but you get to visualize such events.



7. Gamma Ray Burst is one of the catastrophy Earth may face. It is hardly unlikely to happen in the nearest future but the possibility is there. For those who are not aware, a Gamma Ray Burst are short lived bursts of gamma ray photons. the most energetic form of light. These burst lasts from a few milliseconds to several minutes. It shine hundred of times brighter than a typical supernova and about a million trillion times as bright as a the sun, making them briefly the brightest source of cosmic gamma ray photons in the observable universe. (If I sound smart this explanation is taken from NASA Imagine the Universe site. ) It was said that the energy a GRB puts out is more than the whole universe use in the same period of time. Gamma ray burst happens upon a death of a star.

The example used on this documentary is a death of a star that is 8000 light years away. If this occurs during day time, we will be able to witness it and see two suns in the sky. Fun?! Definitely NOT! It would be a horrendous. The gamma ray burst will destroy our ozone layer that protects us from the ultraviolet radiation from the sun. Even if you are hiding in the comfort of your basement, you will suffer from sun burnt. Not only that my fellow bloggers and readers, Molecules will start decomposing and our bodies will stop reproducing new cells and eventually we will be extinct. Yikes!!!!

If for some miraculous way and you survive this, the next thing you will have to worry about would be the development of the black hole. According to several theorists, the black hole is formed after a massive star exploded and collapse. Black holes poses strongest gravity that light can not escape. You might have sometime before the Earth is engulfed by the black hole but there is no way you would be able to escape it.

Amazing Huh! Well I will be saving the rest for tomorrow. I may be late for Earth Day but I will be an EARTH WEEK here in Miss PinkBiik Island.
