i think 2012 will be year for change, nothing more. destruction never comes with warning, so either you're dead or you're dead

and why fear for the extinction of human race when you will attach no importance to it after you die, just hope its not painful

But the earth can't blow up! Thats where I keep my stuff.

lol, you wont care about your stuff after you die anyways

There is still mass in space, just no gravity so the momentum of objects will be slightly lower.

That doesn't make sense.

Momentum is the product of the mass and velocity of the object... Gravity has nothing to do with it...

Gravity affects mass.

Mass x Velocity = Momentum, less mass = less momentum.

*Gravity pushes your body down @ a force of 9.8m/s^2 mu multiplied by your weight. If there was no gravity, it would just be your weight; hence when astronauts arrive back on earth they suffer from disuse atrophy (loss of muscle mass) because their bodies are not used to having no gravity

If you still don't understand, lets just say you'd weigh more on jupiter than you would on earth.

You're getting weight and mass mixed up.

Weight=/Mass

Weight is a force! Force is equal to MASS times acceleration.

However, since the acceleration due to gravity is approximately constant on the Earth's surface (9.8 m/s^2), weight and mass are proportional.

But the momentum of an object is the same on Earth as it is in space. Mass is not reliant on gravity in ANY WAY SHAPE OR FORM!

If you're wondering what mass is in Imperial units, it's Slugs. Weight in Imperial units is Pounds.
In Metric, mass is measured in grams(with kilograms being the standard for calculations, such as for force) and weight is measured in Newtons.

Trust me, I know this like the back of my hand. I'm a senior in Mechanical Engineering for Christ sake!

Just to make sure; I don't believe in this crap, but I found a very interesting list about things that say the world is gonna end in year 2012:

- Maya calendar ends in 2012
- Hopi indians say that the "cycle of life" will end in 2012
- The book of Revelations
- Nostradamus (who predicted for example The American Revolutionary War and The American Civil War), also predicted that world will end in 2006-2012
- Edgar Cayce (1877-1945) predicted that the world will end in 2012
- Aleister Crowley (1875-1947) predicted that the world will end in 2012
- Mother Shipton (1488 – 1561) also predicted that the world will end in 2012
- Earth moves into the centre of our galaxy in 2012
- Some kind of a predicting machine predicted that the world will end in 2012. It also predicted The 2004 Indian Ocean earthquake right.
- The Bible Code
- Nibiru/Planet X
- CERN's LHC gets an update in 2012

Yeah, my english isn't very good, the text I originally found was Finnish so I had to translate it.

seriously we can't die in any apocalyptic manner. I have a belief that humans will neither die nor will there be world peace. Confusing confucius says "man is naturally good but education" will Buddy Buddha said "Follow the middle path." Persians talked about Zorroastrianism and have good god and bad gods. Yin and Yang bla bla bla,

Vishnu will suddenly with a horse, that means its the end of world jesus said about the apocalypse mayan candelar ends in 2012 and china turned into a communist.
