Question

Can you find gravitational force in space?

Answer 1

yes if you know the distance to the nearest massive object,

Answer 2

Yes, by using F=\[\frac{ -GMm }{ r^2}\]

Answer 3

unlikee g on earth G is constant in space

Answer 4

1) if you mean is it there, then yes. the gravitational effect of your own little finger extends all the way through the universe. it runs in theory to infinity, and follows the inverse square law, but can a pretty small number and will be netted out against the gravitational effect of everything else in the universe

2) if you mean can you detect or measure it, then again yes. all you would need is a simple spring and mass. if there was a gravitational force acting upon you whilst you floated through space Gravity (the movie) style, you would detect the force by an extension in the spring following Hook's law. of course, again the force might be super small and your spring might need to be super sensitive.
