    in space if the ball is at rest with respect to another ball at rest and no gravitational or any other sort of force is acting on that ball then will those balls still be at rest for forever????

    You have heard of Newton's Laws of Motion, right?
    Specifically his first one.

    (But, of course, there will be gravitational forces between the two).

    i know newtons law,,, but in space i think nothing can be at rest with an imaginary rest object if both of them donot experience any sort of force ( not even from each other),, is it correct?

    IF you are at rest THEN your time passes with the highest speed possible!

    What?
    Rest ONLY applies relative to something else.
    If no force is applied then an object at rest will remain at rest.

    1) Time wasn't mentioned.
    2) Time passes at 1 second per second - that's it's "speed".

    well time is affected by gravity,,, but this wasn't the thing asked here,,, i wanted to know just that can the ball remain at rest with respect to another imaginary ball at rest?? plz guys give straight answer

    To reaffirm what has already been said. If no forces are acting on the balls then they will remain like that indefinitely. However, since they are material objects they must have mass. If they have mass they must be exerting an attraction on each other. Therefore your original scenario cannot exist in reality.

    You have already been given the answer: if there are no forces acting on either ball then they will remain at rest relative to each other.

    The straight answer is no, because there is always a gravitational force between those balls, no matter how far apart they are.

    if we place a device on each ball which negates the graviation and makes them neutral.

    We are in a galaxy that is moving at over 1 million miles per hour. Since that is the case everything is never at rest for everything in the universe is moving.

    well guys what in case of a drop of water in space with an imaginary ball from which to measure its state of rest or motion and with absolute no force????

    If there is no net force whatsoever ( i.e. if you disregard gravity entirely ), then there will be no net movement. They will remain at rest relative to each other. Bear in mind though that this is not a realistic scenario.

    You're either seriously confused or phrasing the question incorrectly.
    Everything is at rest compared to some arbitrarily specified "imaginary ball".
    All you have to do is define this imaginary ball as "at rest" with regard to whatever you're discussing.

    Every time this sort of question pops up the old question of what is reality raises its head.

    Although I agree with what Marcus said the question remains what is reality?

    Reality

    From Wikipedia, the free encyclopedia


    For other uses, see Reality (disambiguation).

    Reality is the state of things as they actually exist, rather than as they may appear or might be imagined.[1] In a wider definition, reality includes everything that is and has been, whether or not it is observable or comprehensible. A still more broad definition includes everything that has existed, exists, or will exist.
    Philosophers, mathematicians, and other ancient and modern thinkers, such as Aristotle, Plato, Frege, Wittgenstein, and Russell, have made a distinction between thought corresponding to reality, coherent abstractions (thoughts of things that are imaginable but not real), and that which cannot even be rationally thought. By contrast existence is often restricted solely to that which has physical existence or has a direct basis in it in the way that thoughts do in the brain.
    Reality is often contrasted with what is imaginary, delusional, (only) in the mind, dreams, what is false, what is fictional, or what isabstract. At the same time, what is abstract plays a role both in everyday life and in academic research. For instance, causality, virtue,life and distributive justice are abstract concepts that can be difficult to define, but they are only rarely equalled with pure delusions. Both the existence and reality of abstractions is in dispute: one extreme position regard them as mere words, another position regard them as higher truths than less abstract concepts. This disagreement is the basis of the philosophical Problem of universals.
    The truth refers to what is real, while falsity refers to what is not. Fictions are considered not real.

    The "question" is irrelevant to this topic.
