I was always amazed with how the gravity provides a round planet to have objects stay on the ground regardless if the planet is upside down or rightside up. I am also amazed on how the Sun's gravity keeps our planet in the perfect position to promote life.

My question is: So what is creating the gravity to keep us on the planet? Is it from the Earth? If it's from the Earth, is it caused by the radiation from the Earth's core? I was always curious about how gravity works.
 
WTF?!?! I was in OT when I used the "post" tab. Ugg maybe I am stoned! Hahaha
 
The God Particle, of course.
 
It's okay Mags, a little sagging after breast enlargement surgery is normal.
 
P.S. mags, did you get the answer you wanted, or do you want a more specific ansewr? I'm not trying to be snide, so forgive me if it comes across that way.
 
The God Particle. No shit.
 
All objects with mass have gravity even if you were floating in space next to a rock each of you would have a graviational pull on the other. That pull would be super super minor for just you but the earth is many times bigger so the graviational force is many times stronger. Objects become spheres since a shere has the largest volume for the smallest surface area. All the items on earth are pulled towards the middle of the earths core so natuarlly they form into the most compact shape which is a sphere.

But how does a particle feel the gravity?

All things with mass bend space-time. Something tiny has very small gravity. Something huge, like a planet, really bends space. You can jump up in the air, which is like climbing out of the well made by the planet bending space-time. Since you don't have continuous velocity, you come back to earth.

Gravity is a weak force because you can pick up a nail with a magnet and gravity doesn't prevent it. Magnetism is a stronger force.

And I don't look at gravity as something with mass pulling you towards it, but rather the rest of the universe is pushing you towards it.

unfortunately general relativity (inc. mass bending spacetime) doesn't seem to be easily frameable in terms of quantum mechanics, so one of those theories likely has to be an approximation of something deeper, if not something entirely different.
 
I wisely practice Einstein's old saw, "A stitch in time saves nine." He proved with real math.
 
Some good science answers and some bs. Particles don't "feel" gravity. They interact.

Gravity, incidentally, is the weakest of the four basic "forces", in quotes because the word "force" does not really accurately describe them (gravity, electromagnetic, strong nuclear, weak nuclear) but it is the one "macro" objects like animals, plants, people, planets et al are most familiar with because it is the only one that can work at long distances. Actually we also experience the other three but we are not aware of the protons in the atoms in our bodies (strong nuclear) or how the atoms hold together (electromagnetic) or how they decay (weak nuclear).

Mental decay, OTOH, is VERY familiar to anyone who reads web sites....

I disagree I can feel the EM force right now as my fingers don't go through the keyboard. I was just trying to a wise ass and bring up gravitons and higgs bosons.
