why is there gravity among planets and sun ?

Question

what is the reason for existing of gravity between great bodies.

Answer 1

space time is like long fabric with the suns and planets sitting on top of it. the weight of the planets and stars causes the fabri of space time to stretch into a sort of hole. when smaller objects get near the large dip in the fabric the begin to fall into the hole and spin around the inside of it. this effect is known as gravity.

Answer 2

Gravity is one of the forces of nature. And it is actually the weakest one. Yet we seem to think it is the most important one. Consider the forces that keep the atoms and the molecules, that make up your body, together. They are many magnitudes greater than gravity...
All matter "generate" gravity. Gravity is always attractive and work on intergalactic distances. For these reasons it is the only force that can overcome all the other forces despite being the weakest. So all bodies with mass excerts an attractive force onto another body of mass. The exact reason, and why gravity is so weak, is not yet quite understood. But it is known that gravity warps space/time. The answer probably lies therein.

Answer 3

You are comparing two things that have almost nothing in common; chalk and cheese really. The movement of the planets around the sun has no connection with, or influence on, the interaction of people on earth. If you choose to describe the movement of planets as being "in harmony", it says much more about your human perception than it does about planetary dynamic or orbital mechanics. There is certainly no way in which planets "choose" to interact the way they do. They do not work together. They have no thoughts. Humans, on the other hand, DO choose to behave disharmoniously. In doing so, however, nobody's perception of their choices of behaviour include anything like planet-like motion. People have things like beliefs, ambition, jealousy: parameters of sentient beings.

Answer 4

Read up on Einstein's theory of general relativity. The theory is the supporting theory of gravity.

General relativity states that space is made up of a 'fabric' of four dimensions, length, breadth, height and time, otherwise known as spacetime.
The presence of mass would distort spacetime, similar to how a soccer Ball would distort the flatness of a stretched bath towel
In turn, the shape of the surrounding spacetime would tell mass how to behave itself, like a marble placed on the towel with the soccer ball would roll towards the soccer ball.

This is the general gist of it. If you want to find out more, read up on General Relativity

Answer 5

Anything that has mass has gravitation. The larger the mass (eg:sun) the greater the gravity. Even u have your own gravity but your mass is too small and thus negligible.

Answer 6

All planets in the universe has gravity, primarily to prevent friction,bumping to one another that can cause possible explosion.
If we don't have a gravity like here on earth everthing are floating just like bubble, jellyfish no direction.This the wonder of God's creation, which man can'nt totally explain thing how? and why? there's a limitation on what mans knows,

Answer 7

No one really knows. Some particle, called gravitons, have been proposed as being the "responsible" of gravity. But, as far as I know, this has never been proved

Answer 8

i basically agree with Go Cubs.

that is pretty much along the lines of what einstein's theory was.

this link has a video on it that explains the forces of nature.

and some other pretty interesting videos in case you're curious.

Answer 9

F = G(m1)(m2)/r² where
F is force (in Newtons)
m1, m2 are two masses (in kilograms)
r is the distance between them (in meters) and
G is the gravitational constant (6.67259 x 10^(-11) )

Answer 10

it has to do with mass
apparently even a table grape has a small amount of mass and gravity..
