What do we know about gravity; we know that on earth gravity acts on every object known to us here on earth, nothing escapes the gravitational attraction from earth inner core. And if we consider everything on earth share the same building blocks (atoms),then the attraction must relate to a part of the atom ;
either the proton, electron or neutron.
Protons carry a positive electrical charge, electrons carry a negative electrical charge and neutrons carry no electrical charge at all. The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons 'orbit' the nucleus. A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons.
Protons and neutrons are both composed of other particles called quarks and gluons. Protons contain two 'up' quarks and one 'down' quark while neutrons contain one 'up' quark and two 'down' quarks. The gluons are responsible for binding the quarks to one another.
It is possible that every atom on earth also produces Gravity and is attracted to other atoms is the same way ,such as us, are we producing gravity but only on a small scale, not enough to be affected by the greater gravitational force produced at the earths inner core.
So what could this inner core consist of ,to produce a superior gravitational force, I would suggest that it could consist of anything, but the only overriding requirement is that it is immensely dense, i.e. well compacted almost like a small 'black hole" but visible.
So you would in effect have a huge amount of Atoms compressed into a small space, but producing a superior gravitation force that is attracting every other atom on the earth surface.
This would explain why other objects in space produce gravity, but don't necessarily have to share the same material make up.
