Re: Holy Crap
Hi Purplebear,
I am more confused after 6 pages. I know gravity is the "gluey force" which holds me to the ground.
Gravity isn't a "force." That is Newtonian physics, and about 100 years old, as a concept.
But what the heck is it? Damnit I wish someone knew.
I think you meant to say "damnit I wish I knew what it was."
Gravity is the effect of mass density curving spacetime. That is what gives the impression that it is an "attracting" force.
Here's a quick video that explains it with an easy to follow analogy.
Hope this helped,

Petition to Bailout Comedy The Laugh Factory is imploring Congress to immediately fund what owner Jamie Masada calls an "Economic Cheer-Up." If Congress fails to act quickly, the Laugh Factory comedians are planning to march to Washington and plea to President Obama.

something tells me you wanted to be, too
Let me see. Einstein's theory of general relativity where he dealt with gravity was published in 1916. 2009-1916=95. Ok, you made it under the wire.
So much for my "about".
