You live in Seattle, too? Damn, we're starting to flourish like terrible acne. We have like five people now in the pacific NW who post on this forum.

Some of you guys physics majors or something?

Because that equation is only applicable to point-size masses ; people mistake it for spherical masses with constant densities (that's why they can't determine that r>=r1+r2 [r1 and r2 are the radii of both masses] and so if you look at the domain of values, you'll see you're missing a set of possibilities.
Look up Gauss's theorem, it should help you.
EDIT:
Also, consider this (God you've made me horny):
Say r = 0 for your equation; whereas r is the distance between the cg of two objects [spheres, for our example
] you can say:
mass m1 &amp; m2
(Because, for our sake, we're assuming r = 0)
F then becomes = Infinite
So then function (F) yields a vertical asymptote at point r = 0 ; therefore, we can say the function fails.

so why does G=(m1*m2)/r^2?
I've been trying to figure that one out for a while..... though it seems like pretty much everybody has. I think if you figured that out, you'd be a rich man.

I understand the equation and when it works, but I don't understand WHY two masses attract. Neither does anybody else, insofar as I understand.

I PMed Liefer saying he should start threads on various forums to see if there's enough Seattle folk for meetups. I guess that makes 3. :P

But yeah, I've tried to get a Seattle/eastside meetup, but I don't think people are down for it. Here, I'll link you to the off-topic page so you can say you want to join in; give the thread a free bump and let's try to attract more people!

Its funny that this started out as a thread about snow pics. Einstein's General theory of Relativity describes why two massesare attracted to one another. Leifer, how do you know about fourier transforms, pde's, or anything about quantum being only 18. Did you go to some 1337 school that teaches you advanced courses at the highschool level?

Haha, just kidding. I don't know, my brother was super good at math when I was younger, and I always thought it was cool how I was learning how to FOIL and he was learning derivatives and limits in calculus; so I went ahead and ... bought ... two books on Quantum theory. I found it immensely interesting, and at first I didn't understand it, but I've gotten better. I don't know *anybody* who can help me out on anything relating to it, so I kinda stopped. But I guess that can change now, eh?

No, I do alot of drugs though.

Haha, one of my best friends smoked some pure hashish and he drew a diagram of what he "saw" when he examined light. When he sobered up, he took the picture to his uncle, who is a quantum physicist, and the guy **** his pants. Apparently, his diagram shows what light is, and how it functions relative to our three-dimensional world. I have a copy sitting right next to me, but it's really trippy.
