I don't think we should spend billions of dollars on collecting rocks on the moon, or studying saturn's atmosphere, when there are people starving in africa and even here in the united states. Its a waste, we already know these planets are inhabitable. If we going to spend money on space, we should buy a laser satellite to blast asteroids if they are coming in our direction. Anything else is just plain wasteful. Your thoughts, please.

Or petitions out there for investigations on the this drugs side effects?? This med is storing in your fat cells and slowy or some cases fast...killing people. My 37yr old brother just died on Jan 17 2007 from an accidental overdoes of this medication. The coroner and medical examiner told us that it stores in a persons fats cells and only a small percentage will pass through your body and the rest just stays there. Being that it eventually kills you. I have not had one doctor tell me this in the almost 4 years of taking this for a broken spine. Anyone out there?? Know of anything to help change this??

E how much to the Interstellar System, they emit cold microwaves (negative electrons) that also the Land arrives. The Land dust its time, receiving these energies, provides to the balance of the lives of all its species. E as gratefulness, returns for the respective sources (nêutrons) for its subsistence. You approve what Designer Tarcísio Brito says?

A 5kg object is released from a resting hieght of 12m on a curved frictionless ramp, at the bottom of the ramp is a spring with a force constant of 150 N/m. the object slides down the ramp and compresses the spring to point z on the spring before coming to rest.

Find Z
DOes the object continue to move after it comes to rest?
If yes how far will it go up the slope before coming to rest?

I rather shoot myself in the knees that handlin a cockroach, especially the big ones. They are scary, filthy and sneaky as they always apear when it dark. Just writing about them makes my stumaxtwsit.

There is talk about going back to the moon in 2020, why don't NASA update the old saturn five( from the 60s )and use this this proven technology that worked fine back to get man to the moon and back, rather than spend billions of dollars on a new unproven space craft?

Is it really true that our Solar Syatem will be travelling through the Galctic Center of the Milky Way on Dec. 21 , 2012? Is it true this alignment we will see on the winter solstice of 2012 is a once in 26,000 year event?

This is in reference to the Mayan End Date, and if all the hype is based on the fact that this event is actually about to take place in 5 1/2 years. So if anybody knows astronomy enough to say for sure if this is actually taking place , i'd very much appreciate it.
