What is gravity?

Question

If atoms have an electromagnetic charge (eg protons and electrons) is gravity caused by electromagnetism? Or perhaps electromagnetism as me may not now know it? Gravity is typically linked with mass; more mass, more gravity. What causes the gravity in the first place though? If the more mass something has the more gravity it has, then isn't that a buildup of all of the electromagnetically charged atoms in that thing? If not, what evidence is against this?

I think many people missed the point of my first question. Why can gravity not be explained by electromagnetism? What is the proof against it. It seems to me, the closer something is to something is to something else, the more they are attracted by gravity. For example, if I am floating in earth's upper orbit, not actually orbiting the earth, don't I move slower to earth than I would if I was on the earth's surface? It seems to me that I see the same effect bringing two magnets together. Had they been separated by some space, and perhaps in space to get rid of friction, the magnets will move together slowly, but the closer the magnets are the stronger they are attracted and therefore the faster they move closer to each other. Why can't gravity be a form of electromagnetism? What evidence can be held against this theory? And don't link me to wikipedia, think about it yourself and give me an intelligent response.

Answer 1

Well, let me tell you in the first place that gravity is defined as a force the origin being mass. we know that it exists and hence we know the gravitational force . there is no issue as to why it exists( just like quantum mechanics , where experiment is the ultimatum. it happens, though we don't know why.)
electromagnetism has a role to keep an object together, not to keep 2 distinct objects at a great distance together. these r short range forces which become insignificant over a certain distance only.
tell me how do you explain that earth revolves round the sun.

assume that this is electromagnetic. then also say that hypothetically earth and sun have 10^(-13) amount of free charge each.(though they are not supposed to have any free charge in reality)and we are talking of 1000000 free charges moving, mind you.

now if you calculate gravitational and electrical forces you will get your evidence. and also let me tell you that if you r talking of individual charges causing attraction and hence gravity , then there are both repulsive and attractive forces which cancel each other , so we r forced to consider the net charge.

i hope that i done justice to your question. give me a reply.

Answer 2

Gravity is the force which pulls you towards the earth. Like the electromaagnetic feild there is a gravitational feild too.
That is why when you are in outer space you float. If you put anything from a high place to a lower place it will fall down. But in the sea a boat will not fall down because the water gives something called the upthrust. If you put a stone it fall to the bottom because it does not have the shape of the boat.

Answer 3

Gravity and electromagnetism are two different things. Each is a force, with specific laws and characteristics. Gravity is just the attraction that any object with mass has for any other object with mass. It is independant of electric charge or current. Neutrons (which have zero charge), are attracted to each other.

Answer 4

gravity is the weakest of the four fundamental forces (the others are the strong force, electromagnetic force and weak force). gravity is an inherent property of all matter (anything with mass, even an electron)
gravity is different and separate from electromagnetic force. even magnetically and electrically neutral matter such as two neutrons are attracted to each other because of gravity.

Answer 5

I thought I read somewhere that gravity is one of many forces of electromagnetic forces????

Answer 6

earth's magnetic pull.
