In earth science we are learning about all the planets and thier gravity fields and such. My question is where does gravity come from and what creates it?

Gravity is bending of space towards mass.

The bend in space causes objects to 'fall' into a large mass object.

Like a bowling ball put into the center of a trampoline. The bowling ball will bend the trampoline fabric. Spin a golf ball along the outer edge and it will slowly spiral into the bowling ball. Likewise, on cosmic scales, objects such as the sun bend the fabric of space-time, and smaller objects attracted to it simply are falling instead of being pulled.

Originally posted by nchs09 meh im fucking wasted, its hard to type what i was thinking... but let my try to explain it.. if i am wrong someone correct me imagine a bowling bowl sits in the middle of your bed. if you put an object near the bowling bowl it will trickel down to the bowlingbowl because there is downward tension on the bed. supposedly to this theory, space works in the same way... the sun,a HUGE object creates tension on space making anything that is close to it (relativly close) is attracted to it... now if that object is in movment, it will continue to rotate around this object. if it is not in motion it will continure to drag towares the bigger object.

it's not necessarily the size [although thats a good generality], but the mass/density of something.

if the moon was the size of the sun, but still made out of the same material [i.e. rock], it wouldn't have as great of a gravitational affect of the sun [molton gas, or whatever]

Originally posted by tubularbills basically speaking, everything that has mass [i.e. matter] has a gravitational pull to it. however, it is not until you get to something as massive as the planets do we notice/understand gravity. while you yourself have a mass, it's miniscule compared to the planets/moons. this is why things don't "gravitate" towards you. think of it this way, if your wang had the same density/mass of the Earth, you'd have women [and i guess gay men, really] flocking to you.

talk about a perfect way to explain it... a way you will not learn in school

well the earth has a huge mass....

earth to sun has a more equal mass than a person to the earth. a lot more... so that is where the theory corrects itself, if it was unclear before.

Do we actually know what causes gravity? Not what it is or how it works, but why it is that mass has this effect on the space around it? I've seen a fair few explanations for 'how,' it works, but none for 'why,' it works that way.

yo, nchs. in theory v theory, would you throw String Theory in the rubbish bin or do you think it has an acceptable application?

see the posts above you

they are just theories though, just like anything in science.

wow, thanks for the explanations. It's cool to learn something new everyday. My teacher did not even know the answer to this. Thanks a lot you guys.

i have no idea what that is.

he knows that answer. to be able to teach you @ least have to know that.

I'm in a similar situation with my Sociology teacher, so I feel very sorry for you that you're paying money to be "educated" by someone who doesn't know what they're talking about. The only difference is that while yours just didn't know what gravity was, mine claimed that Da Vinci’s painting of The Last Supper, The Sims, the internet, McDonald’s and (you’re going to think I’m kidding with the next one) stop signs are all strictly American.

Yeah, my jaw hit the fucking floor with that one.

Da Vinci's 'The Last Supper' is American?

Last Supper painted in 1498
US Independence declared in 1776

Seriously Idoru, you need to set fire to that retard. I recommend a high octane fuel.
