heavy masses distorts the timespace fabric, because of the gravitational pull. they are both interelated.the less dense an object is, the less gravitational pull it has.

Crash course on general relativity:
Law of inertia says that if there isn't a force, there's no acceleration. It stays at the same velocity. Curvature of space-time comes about from the attempt of eliminating gravity. Something in orbit is in free fall, with no gravity forces acting on it, and traces out a curved path that is a straight line in that particular curvature.
This however is a bit dissatisfying for me. Sure, it's a very nice geomtric representation of gravity; however, I do not like to consider it to be absolutely true. It makes sense to me that curved space does make things very nice, especially when dealing with other forces that would inevitably complicate the scenario. Just change the coordinates via a 'nice' transformation, and poof - gravity disappears.
First, what causes space-time to curve? It's mass and energy.
Second, how is curvature calculated? It's a function of the flow of energy/momentum in the different directions.
Third, what is the mechanism curves space-time? The only answer I see could be gravity.
This is why I can only consider curvature to be a desciption of gravity, not the cause.

Gravity does not distory the space time fabric. It distorts the space fabric. It has nothing to do with time in the general sence. The presence of gravity like other fields does not distort time.
"I hold that space cannot be curved, for the simple reason that it can have no properties. It might as well be said that God has properties. He has not, but only attributes and these are of our own making. Of properties we can only speak when dealing with matter filling the space. To say that in the presence of large bodies space becomes curved is equivalent to stating that something can act upon nothing. I, for one, refuse to subscribe to such a view." Nikola Tesla

Time is relative to gravity and space, the further you get away from a gravitational body, the slower time goes, therefore the distance you travel through that space is faster when measured by time.
if you are doing 60 miles an hour on the face of the earth
and you move to some place that is 8 billion miles away from a gravitational body, time would be slowed to practically nothing but you would still be traveling trough space at the same rate. It could take two hours for one second to click by, therefore you would be traveling 120 miles a second..

Wouldn't heavy masses like planet exert gravitational pull on the time-space fabric. I never heard that gravity is the result of time-space distortion.
But how would I know I have no idea what cosmology or quantum physics might be

Douglas Adams (science fiction author, wrote the hitch hikers guide series) summed up General Relativity this way:
mass-energy tells space-time how to curve, space-time tells mass-energy how to move
This is actually a pretty fair summary of GR. Symbolically GR is represented this way:
G(mn) = 8.Pi.T(mn)
On the left hand side is G, the symbolic Einstein tensor. It contains all the information about how space-time is curved. On the right hand side is T, the stress-energy tensor. It contains all the information about local mass-energy. The interrelation between the two is "gravity".
Hope this helps!

Yes it does; yet gravity IS a manifestation of the disortion of space-time by masses. However in Einsteins General Theory, the distortion of space-time is determined by the mass-energy-stress tensor; because of the equivalence of mass and energy (e=mc^2), the presence of energy also has a space-time warping effect, and the gravitation field itself contains energy. This is one of the reasons solving the General Relativity field equations is so difficult: Mass distorts space-time producing energy which has a mass equivalent which changes the amount of distortion.

those are 2 completely distinctive questions, by way of fact a planet, by employing definition, is a few thing it quite is already orbiting a celebrity. that's no longer good for 2 planets to share the same orbit, the closest it quite is a threat is for a planet to share its oribt with a minor physique at certainly one of its Lagrange factors. it would be so minor that it would be moot to talk of "the two certainly one of them sharing an elementary moon", as despite that moon is may be orbiting many times the proper planet physique. contained whilst it comes to 2 planets on distinctive orbits, with distinctive orbit cases, that's wildly inconceivable that there is additionally a good orbit for something between the two, and purely those 2. contained whilst it comes to binary stars, see the different solutions already given. Addendum: the problem with this question is the definition of a moon. What makes a moon? And what does it recommend to "share an elementary moon?" Worse, what's a planet?

Though Newton thought he figured it out, gravity is one of the least understood of the 4 forces.
The inverse square law states "All fields are mathematically infinite". Each field source is a ripple in space time. Space time conforms to the contours of gravitational fields because space time itself seems to be a product of the same energy source which creates the said fields.
The curvature of space around heavenly bodies and the mutual attraction of field sources seems to suggest that gravitational field sources pull space into themselves. Bodies in physical contact are creating the illusion of attraction through the dilation of time and curvature of space.
Matter is the central distortion of a definable field with in the space time continuum. The warping of space time creates a central distortion with in the nucleus of the atom at maximum velocity. The velocity of the atom opens a temporal doorway allowing the atom to recharge from zero-time (pure energy). Energy emanating from the energy base of space time allows the atom to sustain itself in this entropic state. To answer your question, gravity creates the warping of space time as a byproduct of the temporal doorway created by the atom. Atoms are oscillating many singularities which create temporal distortions in the fabric of space time.
I don't perceive gravity as the result of time space, but perhaps rather an influence in the distortion.

Time is just a fabric, as is gravity.
Imagen a blanket, some threads are gravity some others are time, ect, you put a heavy ball on it and the blanket dents twords the ball, effecting gravity and time. That's just all it is.
