No effect. They're so far away their magnetic and gravitational fields have only the most infinitesimal influence on the Earth.

You are correct, but the effects are so insignificant, it doesnt nearly matter.\n\nAll object in the universe have a gravitational attraction to one another.\nTake the Earth and bowling ball example,\nThe Earth exerts a force on the bowling ball, and the bowling ball exerts a force on the Earth.  Both on these forces cause the other object to accelerate towards a common center of mass.  In the case of the Earth's gravitational force on the bowling ball, the force is huge in comparison to the bowling ball's force exerted on the Earth, so much so that we can easily neglect the 2nd force.\n\nLets look at some numbers.....\nIf we say the Earth has a mass of 5.9742 E24 kg and say we will say we have a very heavy bowling ball with a mass of 1000 kg, then we can calculate the gravitaional force between them if we know the distance.  Lets estimate their centers of mass are 6380 (~larger than radius of Earth), we can calculate the gravitational force to be,\nF_g = (G*M*m)/r^2\nF_g = 9789.58 Newtons, which would cause an acceleration of 9.7895 mm/s^2 for the bowling ball and a miniscule 1.63 E-21 m/s^2 for Earth.  To put that in perspective of just how slow acceleration is, if you were to accelerated you car from at a constant acceleration of 1.63 E-21 m/s^2, it would take you about 86500000000000 YEARS to go from 0 to 10 miles per hour!  I think for simplicity sake, Newton did all right.\n\nEDIT:\nYes, the bowling ball very much so does pull on the Earth.  How is the "universe" to know which object is suppose to be the planet and which is the bowling ball?  ALL objects in the universe have a gravititational attraction to ALL other objects.  The Earth pulls in the bowling ball, and the bowling ball pulls on the Earth.  There are 2 equal forces pointed in opposite directions, therefroe momentum is conserved (which is a physical LAW).

Yes gravity does have an effect on light. But your example does not show it. Gravity on earth is not strong enough to have a NOTICABLE effect of light but a black hole has enough gravity to bend light into it. \n\nYou just notice light on the ground because it is a surface for it to reflect off.

zero gravity happens when your weight equal zero because \nW(weight)=M(mass)xG(gravitional force)G IS 0 When u r in space   nothing like a planet or moon affects you as long as you r far from them

This is a bit of a "layman's" answer but here goes:\nSpace, not just the world we all live in, but all the space in the universe is "affected" by MASS (massive objects) in a way that most people do not realize.  Most  people think that gravity has something to do with a "magnetic" force of some kind that causes objects to be attracted to other objects.  The weird truth of it is that "gravity" is a side-effect of the "geometry" of space-time.\n\nWhat does that mean?  What Einstein figured out is that SPACE is actually "warped" or "curved" by mass (or massive objects) like the Sun or planets, or black holes - that sort of thing.  Now while you cannot really SEE this, \nyou can see the "effect" of it.   When an asteroid passes closely by a massive object, it may be affected by the objects gravity and drawn toward it.  But this has nothing to do with magnetism - it is actually the effect of the asteroid following the "curvature of space" (since the massive object - like the Sun - has warped space).  \n\nTo think of a common, simple example: imagine a BOWLING BALL sitting on a large rubber sheet (or your mattress).... you will notice that the massive ball makes an big depression in the sheet, or "dip" in your mattress.  Now imagine rolling a marble across this sheet, or your mattress.  If it is close enough to the bowling ball, it will be "captured by the gravity" (really warped space) and spiral inward toward the bowling ball.  So "Curved Space" is the "warping of space" caused by "massive objects", and what we see as gravity is really just objects responding to the natural curvature of space.  \n\nMany people then ask why an apple falls straight to the ground on earth.  The general idea is that space is "more steeply curved" when close to massive objects (as we are standing on earth) and since we are already ALWAYS in motion (you knew that - with rotation and all), when you "let go" of a ball, it follows the path of least resistance in curved space, which is right DOWN to the ground (now that is a "steep curve").\n-Gregory J. Mallon, La Plata, MD

Gravity is a force which keeps you stay in groud. For instance if you drop a pencil it falls to earth, if you through a ball to sky the gravity slows the upward thrust give by you to the ball & then pull it back to ground. Like this you can gine "n" no. of examples

Gravity, makes your neck go baggy! It drags a lot of things earthbound, especially when you hit 50!

Gravity does not change the mass of an object, only its weight.\n\nIf you travel away from the Earth, or any concentration of gravity, you will weigh less, but your mass is unchanged.

Yes Gauss's Law applies in gravitational fields, BUT with some modification.  I am posting a link which includes the formula.  The formula is under "Gravitational Analogue".  \n  \n  Gauss's law also has to be modified for electromagnetic fields over the surface of a sphere (though the size of the sphere doesn't have an effect on the equation, for some reason).

Extremely little. The Gravity in Newtonian Physics is determined by the mass of the body which is not effected by the state of the matter only its net mass.\n\nHowever in General Relativity not only the mass but the pressure is involved. So in General Relativity increased positive pressure does very slightly increase the gravity. But this added amount is usually very insignificant for most bodies due to the fact that these pressures are extremely small relative to the speed of light.

Ask a scientist and they will say it effects every aspect of your daily activities. You and your surroundings are made of atoms that are mostly empty space. It is swarms of electrons with super tiny yet massive nuclei interspersed. All these forces acting on mass. Strong nuclear force holding the nucleus of an atom together. Electromagnetic forces holding the atoms together, and making molecules. Gravity attracting all massive objects to one another. Nature uses these forces to build planets, stars, even life itself. Engineers use these forces to manipulate matter in ever more amazing ways. Everything you see, hear, smell, or feel is physics in action.

In general relativity, mass affects space and time, causing what we call gravity, and time dilation. The equations predicted that clocks in a gravity field would run more slowly, although the effect is very slight for most masses that we are familiar with, like the Earth. It has been measured and agrees well with predictions.\n\nSimilarly, the equations predicted that light would be bent around a mass, like the sun, and this has also been proved to be correct. In fact, strong gravity sources can create illusions, sometimes splitting the image of a light source behind a high-gravity object so it appears to us to be two separate images.\n\nA new discovery is that the rotation of a gravity source, like the sun or a galaxy, causes "frame dragging", that is, distorts spacetime like water around a spinning ball, also predicted by Einstein's theory.\n\nThere are a lot of good science sites on the web for this information.

As far as I know, they are still not sure as to what creates gravitational force. If they determine the source, one might negate it to experience zero gravity anywhere.

Hey gudrun what question are you answering?\n\nOne thing it helps with is GPS accuracy.  Without accounting for effects of relativity, we would have HUGE accuracy problems.
