in any heavenly body what is that constitutes the gravitational force,is it the soil,crust or the molten core?if so can gravity be achieved in outer space by taking the required stuff outside into the space?

photons in the form of light or other radiation make perfect orbits passing smoothly through all the (10 or 11) dimensions of space-time.
Photons which are in complex orbits around each other (another way to say matter) no longer can pass smoothly, and so they tangle (distort) space. This tangling of space is what we call gravity. The only way to create gravity is to have lots of matter around, or to accelerate or decelerate mass.
The fictional favorite form of a large space station would be a huge wheel, the rotation of the wheel would create artificial gravity.
The lack of gravity in space is a serious challenge to the human body. Astronauts exercise with bungee cords to simulate gravity and keep their body working.

By mass
The soil, crust and the molten core are matter and matter has mass. The mass, according to Einstein, warps space. The warping of the fabric of space creates something that we call gravitation.
It outer space to generate appreciable gravity would require enormous mass. Artificial gravity is easier to archive. By having a spaceship rotate around the axis of propulsion we can generate enough centripetal force to produce artificial gravity. The 'gravitation l' acceleration will be then
a=(V^2)/R
V - tangential component of velocity of rotation
R - the radius of rotation.
And finally - no one really knows where does force of gravity come from.

to make clean all this, Gravity is the weakest of all forces all distances aside. If we save the comparable distance for each stress Gravity will are available in final. the explanation why it is so small remains surely unknown. The bits of string thought that have been stated could be put in context. the component to thread thought is to discover an extremely unified thought wherein there are not from now on 4 different forces yet one million single stress. we've already got here upon that at intense ability stages the EM stress and the susceptible nuclear bond to grow to be a single stress. there is likewise stable evidence that the EM & susceptible mixture would bond with the stable nuclear stress. although, physicists can not at the instant see how gravity suits into all of tis. they're hoping that at rather intense ability stages Gravity will unite will the three others and grow to be the was hoping for grasp stress. Gravity is unquestionably the black sheep of the bunch. So the question you ask is extremely pertinent, although, unresolved.

Where Does Gravity Come From

None of the physical components (..soil, crust, core, etc.,) directly affect the gravitational force of any heavenly body. What does is the amount of mass such a body has. The more mass, the stronger will be the force of gravity around the object. Experimental confirmations of Einstein's relativity have shown that mass actually shapes space. The usual rough analogy is that of a thin rubber sheet (..space) with a bowling ball (..mass) resting on it. Around the bowling ball the sheet will be distorted (..gravity), with maximum distortion closest to the bowling ball.
How mass actually distorts space is not at all understood.

Most of the earth's gravity on us is due to the molten core, which is mostly iron and very large compared to the crust of the earth.
Moving the "stuff" to space would be like creating a new planet and would produce gravity, but this is impractical. Artificial gravity is created on a small scale in space (such as on the International Space Station) by spinning a wheel. Objects placed inside the rim of the wheel experience centrifugal forces which take the place of gravitational forces.

ant two bodies separated by any distance have a tendency to pull each other to themselves.this is what we call gravity.when you are separated by a distance from the ground,the two bodies(u n the earth)pull each other-graity.just like magnetism,it is an attractive force.in outer space if you take the 'stuff' definitely they will attract each other..think of it that the solar system,the galaxies,the universe are your 'stuff' in outer space so they too attract and so gravity is definitely prevalent in the outer space!!!

Gravity comes from mass.
Actually you do not have to bring anything out to space because black hole itself has a lot of gravitational energy

Gravity is an aspect of space associated with matter!

i could say mass ,but that's not really answering it.
the where,how,and what of gravity is a complete mystery at the deepest layers of the problem
