When he dives, due to acceleration, curvature or Gravity disappears. 

No it doesn't. The space that he's falling through is still curved. If the gravity disappeared, he would move with a constant velocity instead of accelerating.

he will definitely transform away from Gravity.

What is "transform away from gravity" supposed to mean?

As it accelerates, gravity weakens and acceleration eases.

Gravity does not get weaker. And normally, I would expect "acceleration eases" to mean that you are decelerating, not accelerating.

When Earth is at inertial position gravity hooked it.

What does being "at inertial position" mean? What does "gravity hooked it" mean?

Ok, how Gravity is intact at that velocity.   

Because there's no reason that it shouldn't be intact (whatever it means for gravity to be "intact").

Yes, of course space time is not empty.  But curvature against the person, who dives is weakens.  So, naturally, he will temporarily transform away from gravity.    When the carnival is at inertial position, there is strong curvature or gravity against it.  As it accelerates curvature or gravity against it weakens. 

Suppose let us imagine that our Earth is in inertial position.  As usual, like any other mass, it curves the space time around it.  Ok, now Earth started spinning against its axis, how the curvature or gravity is still exists.

You're not helping me understand you. Like I asked before, what does "transform away from gravity" and "at inertial position" mean? Until I understand that, I can't know what you're telling me.

Ok, now Earth started spinning against its axis, how the curvature or gravity is still exists. 

Because rotation doesn't get rid of that curvature. It's as simple as that.

DOES MASS CURVES THE SPACETIME, ANYWHERE:
Does mass curves the space time anywhere in the universe.  This is one of the important point in deciding what exactly is gravity.

Ok, as per Newton’s theory of gravity, if we place a massive sphere in space it will start exerting force on all other masses around it.

As per Einstein’s General theory of relativity, if we place a massive sphere anywhere in the universe it will distort space time around it.  In other words space time around the sphere is curved.    Matter tells space how to curve, and curved space tells matter how to move. For the first time, Einstein’s General relativity linked Gravity to space time. Mass warps the spacetime and the curvature of spacetime around mass explains gravity.

Suppose a planet “X” is placed in the space and it curved the space time around it.  In other words, it created its own gravity field.  When it is capable of creating its own gravity field, why planets don’t exists outside our solar system. 

There are 8 to 9 planets in our solar system.  The Sun is at the center and these planets are orbiting the Sun. 

Gμν = 8πTμν
On the left side of the equation is a tensor describing the geometry of spacetime — the gravitational field. On the right is the tensor describing the matter and energy density — the source of the gravitational field. The equation shows that spacetime geometry equals mass-energy density when adjusted with the proper units and numerical constants.
It is very much clear that Einstein equated Gravitational field with matter and energy density. 

So, without source, matter and energy how a gravitational field is created.  Mass is just one part only, curvature or gravity again depends on mass/energy density within that area.  No energy density, no curvature or gravity. 

It is surprise, why we are taking space as empty. 

Planets are curving the space time within a solar system only and that is why they are existing in a solar system. 
Energy density is working like a space fabric.  Outside our solar system, there is no energy density, no curvature, no planet can exist. 

No planet can curve the space time, anywhere, unless there is energy density within that place.  There is huge/sufficient energy density, already present in our solar system, which is aiding curvature.

Science developed a lot, these things are appearing before us.

When the sky driver, escapes due to acceleration, think of Earth, how Gravity hooked Earth at that velocity.

Einstein's Equivalence Principle:

Einstein’s equivalence is an extension to Galileo Galilei’s, relative motion of objects.  He wrote this in 1632, even before Newton published his now-famous work.

“If you are in a closed room on a ship sailing at a constant speed and the ride is perfectly smooth, objects behave as they would on land. There’s no physical experiment you could conduct to tell whether you’re moving or stationary (assuming you’re not peeking out of a porthole).

This is an excellent idea/thinking of Galilei.  When the ship is at constant speed, things in a closed room, behave as if on land.  He compared closed room to Earth. 

By the time of Einstein science developed a lot and he replaced ship to spaceship. 

“Is there any physical experiment you could do within the confines of your spaceship to tell whether you really were accelerating through space (assuming there were no windows to look out from), or if, instead, you were inside a spaceship stationary on the surface of Earth? Einstein said no—just as Galileo imagined the indistinguishability between a person inside a smooth-sailing ship (confined without windows) and a person on land.This is called the equivalence principle”.

Einstein's theory of "Equivalence Principle" asserts the equivalence between inertial and gravitational forces of acceleration. It rests upon the fact that we cannot distinguish between the inertial forces, experienced, in a rocket ship accelerating through space, and the gravitational forces experienced on the surface of the Earth.

01  Equivalence principle tells indistinguishability, between a person inside a closed chamber of space ship to a person on land.
02  Indistinguishability is valid only when two things compared are equal
03  Does a closed chamber is equal to Earth?.  If so, Earth also must be a closed one.  But we are taking Earth as open. 
04  So, equivalence principle is not “indistinguishable”, but “distinguishable”.
05  Ok, engine of the spaceship is on, it started accelerating through space.  Escape velocity is the speed at which the sum of an object's kinetic energy and its gravitational potential energy is equal to zero.  As the spaceship gains escape velocity, for the spaceship “Gravity is equal to acceleration”. 
06  As per Einstein, if we place any mass, anywhere in the spacetime, it curves, which is known as Gravity.  Similarly, there is curvature against Earth also.  At that velocity, how this curvature is intact.
07  If Earth is an open, not having doors or windows, nothing can stop centrifugal force. Thiings may be different.

Finally, we can say that Earth is not an open but a closed one. This is exactly like that of a closed room in a ship or a closed chamber in spaceship. If it is open, then it is not “indistinguishable”, but distinguishable.

This is the same reason why we don’t feel our planet’s movement around the sun.

Space warps under accelerated motion:

“Theoretically, you could be in deep space, far away from all significant mass concentrations and their gravitational influence. The rocket engine of the observer’s spaceship is firing and produces an acceleration of 9.8 meters (32 feet) per square second. This accelerated observer feels as heavy as we would feel on earth, since the gravitational acceleration with which an object on earth falls to the ground has that exact same value”.

Does space time warps under acceleration motion?.
01  It is true that as long as the space ship is at rest or stationary on the ground, one of the space crew, Mr. X’s weight is 75 kgs.
02  As the engine is start and the rocket start accelerating at the rate of 9.81 meters per second, Mr. X’s weight continues to be 75 kgs only.
03  If space time warps under acceleration motion, one’s rocket achieves escape velocity there must be change in gravity.  No such thing hinted by Einstein.
03  Basic doubt of Einstein is that, the rocket is far away from all significant mass and its gravitational influence, in deep space where there is no Gravity, still as long as rocket engines work at exactly the right rate to accelerate 9.81 meters per second, how, things behave as if on land i.e., gravity.
04  In the cabin Mr. ‘X’s weight continues to be 75 kgs.  So, Einstein thought that space time is warping under acceleration motion.
05  In ‘indistinguishability’, Galileo raised two important points, sailing is smooth and  assuming you’re not peeking out of a porthole.
06  So, it is clear that Gravity can be packed in a closed room or space cabin.  And, this packed Gravity behaves similarly to that on Earth.
07 One’s you reaches the destination and Engine is shut, space time start interacting with the cabin.  Since pressure is high inside the cabin, it moves out and equates with outside.
08  Here, effect of centrifugal force is far limited or negligible since there is no change of Mr. X’s weight anywhere.   

How Gravity works on Earth:

I think, the following is the wonderful presentation of Einstein and it is possible for the people like Einstein only.  No ordinary brain can get an idea or think.

“The room you are in could be a cabin aboard a rocket – In such a situation, if you let go of an object, the cabin floor would accelerate towards that object at 9.81 meters per square second – exactly the same acceleration of free fall here on earth. From your vantage point as an observer standing on the cabin floor, you cannot distinguish between the two situations: are those objects falling towards a massive body like the earth? Or is the cabin floor accelerating towards them”.

01 In macro level, this is 100% correct and valid.
02  Ok, there are two planets Earth and Moon.  If moon is in “free fall”, like an object let to go.  In such situation, if Earth raises towards Moon, it is possible to measure or to say, whether Moon is coming down or Earth raising.
03  In micro level, for an apple, Earth raising, impossible to measure or say anything.  For an object to cabin floor, it is ok. 

“This famous principle begins with the recognition that a gravitational force, as we experience it on Earth's surface ("weight"), is actually caused by spacetime accelerating through us on its way to the center of the Earth. We feel the force only because we are unable to follow the natural flow of spacetime which tries to carry us with it. In "free fall" or orbit we are co-movers with the spatial flow, and feel no force at all, as we offer no resistance to its inertial urgings”.

01   In “free fall”, as per Einstein, we are co-movers with the spatial flow and feel no force.
02 Gravity or weight we feel on Earth’s surface is actually caused by space time accelerating through us to the centre of the Earth.  We feel the force, because we are unable to follow the natural flow of space time.
03  In “Indistinguishability”,  it is clear that Earth is not an open frame, but a closed frame.  There is no centrifugal force working against us as assumed by Einstein.  Its effect is far limited.
04  In equivalence principle, we have discussed in detail that Gravity can be packed or moved.  If it is due to flow of spacetime, since it is a continuous process, almost impossible to pack or move.                                                                                                                                                                 

What exactly is Gravity:

From the theory, “Indistinguishability”  it is clear that Earth is a closed frame.  In case, if it is not correct, then the theory is distinguishable, invalid and incorrect.  As pointed out by Galileo, we will get the feeling, as if on land, only when doors, windows are closed and sail is smooth.  If Earth is having doors, windows, in other words an open frame, there is no comparison at all. 

Earth is a closed frame, like that of a room in ship or cabin in spaceship. It paved the way for storage of additional energy.  Since Earth is a closed frame, energy entering space time of Earth cannot move out that much easily. This additional energy is warping the space time of Earth.  It is true that Gravity is matter blind.  Total energy density is stranded against the Earth and it tries to move towards the center of the Earth.

The cabin of the spaceship is closed in a Gravity field only.  This atmosphere consists of high energy density.  The crew inside the cabin gets the feeling, as if on land.  When the space ship reaches destination, engine stops, now high density energy in the cabin, interacts with space time of the space ship and adjusts with it. 

It clearly tells us that Gravity can be packed and moved.

Suppose, Mr. X is standing in an open place and the space time around him is curved.  For the strong density of energy, moving towards the center of Earth, he is an obstruction.  Energy moving, nearby Mr. X, bends, interacts with the curvature, start flowing along with the curvature.  This is Gravity or weight, we feel on Earth.

If Mr. X dives from a high place, in free fall, as thought by Einstein, Energy flow equates.  Here, one more important point is that, Mr. X when he is stationary on the ground, there is strong curvature against him.  In free fall, as he accelerates, curvature against him weakens further and further.  As he approaches, 9.81 meters per second, curvature disappears permanently, in other words ‘free fall’.  This is the same  in case of Earth also.  Suppose, let us imagine that Earth is at rest or stationary, there is strong curvature.  When Earth started spinning, curvature weakens.  But Earth is having a strong frame, by which it is closed from all sides and it is giving protection..

Process of Earth spinning:

01  Initially, all the planets, like that of satellites in the space, curves their space time and are at rest or stationary.
02  Energy flowing in the lanes pushes them.
03  Meanwhile atmosphere is developed, frame never allows energy in the lane to interact with Earth directly.
04  Energy in the open area start flowing along with the lane and drags Earth. 

If Mr. X start moving in upward direction, as energy density in the space time weakens, curvature against him also weakens.   It is true that energy is neither created nor destroyed, it can only be modified one form to other.  A part of the incoming energy towards Earth bounces back and moves to faraway places.  When these forces, incoming and outgoing equate, things at that place are at rest or stationary.

Why Earth tilt or obliquity by 23.5 degrees:

It is said that distribution of mass on Earth is strongly influencing the tilt or obliquity.  Large amounts of land mass and ice sheets in the Northern Hemisphere make Earth top-heavy. There is an analogy for this obliquity, if you spin a ball with a piece of bubble gum stuck near the top, the extra weight would cause the ball to tilt when spun.
 
Distribution of mass and ice sheet in the Norther Hemisphere make Earth top heavy, is just an imagination only. In the case of ball, it is rotating against gravity field, where as in the case of Earth, rotation is due to gravity field only.

What makes earth to tilt:

Einstein eventually identified the property of spacetime which is responsible for gravity as its curvature. ... This is the core of Einstein's theory of general relativity, which is often summed up in words as follows: "matter tells spacetime how to curve, and curved spacetime tells matter how to move".

We have already discussed  that total energy in our solar system is present in the form of layers and there are 8 to 9 layers.  Basically, without this energy density, matter never curves the space time.  It is true that Sun is rotating against its axis, causing flow of energy in these layers. 

Suppose, let us imagine that Sun and other planets are at rest or stationary.  Now energy from Sun moves in straight line.  In such case, there is no scope for rotation or revolution. 

Rotation of Sun is causing movement of energy in the layers.  Space time of the Earth is curved.  Energy in the layer, faces gravity waves from Earth, bends and start flowing along with the gravity waves.  Since there is pressure/force, it exerts pressure on gravity waves of Earth and start flowing along with curvature.  Earth start rotating against its axis.

But rotation of Earth in perpendicular or tilt or obliquity depends on the curvature of space time.  If curvature is in perpendicular or 180 degrees, Earth also moves in the same direction.

Here, space time of the Earth, most curved, at the equator, moves up or down, Earth also shifts down or up.  There are several reasons for the curved space time, changing its path.  It all depends on the availability/distribution of energy density.  Generally land mass influences distribution of energy density at a particular place.  Matter  curves the space time around it.  But curved space time, leads or directs the movement of Earth or any planet..

In this way, curved space time tells matter how to move.

“As we have seen, matter does not simply pull on other matter across empty space, as Newton had imagined. Rather matter distorts space-time and it is this distorted space-time that in turn affects other matter. Objects (including planets, like the Earth, for instance) fly freely under their own inertia through warped space-time, following curved paths because this is the shortest possible path (or geodesic) in warped space-time”.

I had gone by this precise statement several times.  Number of doubts bothers my mind.

01  When matter does not simply pull on other matter across empty space, how it distort empty space time.
02  What this distorted space time consists of, “medium” and how it affects other matter.
03  If Sun distorted space time, how it distorted empty space time, and the extent up to which it extends.  There are number of stars in our universe, do they distort space time around them. 
04  Einstein utilized Newton’s 1st law of motion and the word ‘inertia” in a best way. 
05  Well, do this ‘inertia’ is created after distortion of space time by Sun or is it permanent nature of planets.
06  If Sun distorts space time, it must be 4d space time, but why it is horizontal. 
07  Finally, how this path or geodesic is created in warped space-time.

Well, of course mine knowledge is limited but there are people with excellent idea on Einstein theories, may have their opinion in this regard.

Well, of course it is known fact the astronauts, along with space station experiences weightlessness.  The astronauts’ weightlessness is due to the fact that, along with their station, they are in free fall.

It is surprise to see, how free fall is causing weightlessness to the astronauts and space station. 

About Free fall:
Suppose, you are in an elevator, and the elevator is in a Gravitational field of a mass, for instance that of the earth.  If the elevator is in free fall. In that case you, everything else within the elevator and the elevator itself would all be accelerated at exactly the same rate so that, inside, no influence of gravity could be detected.

Along with the elevator, objects faithfully keep their relative positions or move at a constant speed, just as they would in a gravity-free region of space. You, as the elevator’s passenger, would feel weightless. Thus, inside an elevator, we cannot decide whether or not we are in a gravitational field or not. 

Here Einstein equated to a passenger in an elevator falling freely to a person in free space who feels weightless due to free fall.   

Let us imagine that Mr. X is in an elevator, moving at a constant rate, in other words Mr. X and the elevator is in free fall.  Ok, Mr. X is in weightless condition. 

Weightless due to free fall of elevator, no doubt, 100% correct. 

Basic point is, weightless  in a gravity free space.  Mr X is already in space, gravity free region.  Whether Mr. X is in free fall or not, he is in weightless condition. 

Now, take that Mr. X and the space station are in deep space.  Let us imagine that they are in at rest or stationary.  At that point, they are not gaining any weight. 

There is no relevance to free fall in an elevator to free fall in a deep space.     

Free fall in Space:

“Not, in the kind of free fall that takes them directly towards the earth, but in free fall that takes them around the earth – in earth orbit”. 

Let us analyse, why space station orbit Earth:

It is true that Sun itself is not at rest or stationary.  It is rotating against its axis.  Sun is the base for total Energy in our Solar system.  While moving it is dragging energy base in the solar system.  In other words there is a flow of energy. 

When a huge mass is placed in space, it curves or distorts space time around it.  It is now in weightless condition.  Energy flowing in the space exerts pressure and it start moving along with it.   

On Earth’s surface, curved space time or energy density is not coming from Earth.  Energy flowing in the space, lanes, faces tidal force moving out from Earth, bends and start flowing.  The energy flow creates pressure against tidal force and it drags the planet. 

Huge masses gradient, difference in energy into open space.  When the rocket accelerates, tidal forces start aiding it.  As the Gravity decreases, tidal forces start gaining strength.

On the other side there is flow of energy towards the mass. Astronauts, space station every mass curves the space time around them.  Energy moving towards Earth, bends and while moving along curved space, drags it.   It  creates pressure against space station.  However tidal waves moving out, in turn creates opposite pressure.  Since both forces are balanced the space station is at rest or stationary.   The flow or movement of energy drags the space station, along with Earth and makes it  to go in Earths orbit.

Here, ‘inertia’ is not right of the planets.  All the planets, continues to be at rest or stationary unless a force is acted upon by them.  And thus no ‘inertial forces’ exists.  Curvature only throws the planets into inertia i.e., at rest or stationary, but it cannot give inertia i.e., rotation against its axis.

This may describe one aspect of gravity; bending of space-time, but it ignores the other side of the coin, which is the pressure exerted by gravity via mass. This secondary affect, if you look closer, is the opposite of the direction of space-time, in terms of time. Gravity, as an acceleration, has the units of d/t/t, or gravity is two parts time and one part distance, or space-time plus time, with the second time connected to the Newtonian pressure.

As an example, nuclear fusion occurs in the center of our sun. This where the gravitational pressures are the highest. These core fusion reactions release the most energetic quanta of energy, implicit of the fastest frequency quanta and material transitions.

In terms of space-time and gravity, distance and time both contract the most in the core. When it comes to pressure and matter, distance contracts, but time; frequency, get faster, based on the phases induced by the pressure. Time goes in two directions, while distance goes in one common direction, as implicit of d/t/t. 

GR tells us something about gravity with respect to the curvature of space-time, but this is not the whole story. Gravity is not a one trick pony. There is also a Newtonian pressure affect that defines the phases of mass and matter; universal diversity of materials in space-time. This uses a second time variable, that moves in the opposite direction of the GR time aspect.

The black hole has space-time contracted to nearly a point and time essentially stops. The pressures in the black hole will be extremely high, since so much matter is compacted into such a small space. This will generate exotic phases of matter with extreme frequency, which is the opposite direction of time in space-time.

Energy emissions would red shift, if they could leave the black hole. This slows the frequency; slows time, even though time, via space-time, expands or speed up outsider the black hole. It appears gravity help matter-energy and space-time normalize, via time.

[Bobolink]

This may describe one aspect of gravity; bending of space-time, but it ignores the other side of the coin, which is the pressure exerted by gravity via mass.

Gravity is the bending of spacetime, period.  Gravity certainly can give rise to pressure, but nobody ignores that.

Gravity, as an acceleration, has the units of d/t/t, or gravity is two parts time and one part distance, or space-time plus time, with the second time connected to the Newtonian pressure.

That is gibberish.  Acceleration is dv/dt.

In terms of space-time and gravity, distance and time both contract the most in the core. When it comes to pressure and matter, distance contracts, but time; frequency, get faster, based on the phases induced by the pressure.

This is a startling misunderstanding of some basic concepts.  If matter is heated then the atoms move faster the black body radiation frequency increases but time is unaffected!  Frequency is not time, does that really need to be pointed out?

GR tells us something about gravity with respect to the curvature of space-time, but this is not the whole story. Gravity is not a one trick pony. There is also a Newtonian pressure

Newtonian pressure or as the rest of us refer to it, pressure is a consequence of GR (gravity).

The black hole has space-time contracted to nearly a point and time essentially stops. The pressures in the black hole will be extremely high, since so much matter is compacted into such a small space. This will generate exotic phases of matter with extreme frequency, which is the opposite direction of time in space-time.

Do you have any evidence for this flight of fancy?

Energy emissions would red shift, if they could leave the black hole. This slows the frequency; slows time, even though time, via space-time, expands or speed up outsider the black hole. It appears gravity help matter-energy and space-time normalize, via time.

Just some word salad to wrap it all up...

“Let’s imagine a cylindrical carnival ride where you and your fellow passengers are pinned to the outer surface. The cylinder is rotated faster and faster until the acceleration eases and the movement stays constant. But even once the speed is constant, you still feel the accelerated motion—you feel yourself being pinned to the outer edge of the ride”.

This is another important point in deciding “what exactly is gravity”. 

01 Ok, let us take carnival is at rest or stationary.
02 Now, rotate it faster and faster until acceleration eases.
03 It is true that every mass, including carnival curves the space time around it.
04 When the acceleration eases and the movement is constant, what about curvature,  and the gravity.

Instead, for better idea take a globe, approximately 3 kgs weight.  Now rotate the globe with maximum speed.  One’s the acceleration eases, its weight, definitely may not be 3 kgs.  Initially globe also curved the space time around it.  As the acceleration gains, curvature weakens.  In other words gravity.

Now let us compare globe to Earth.  Let us take Earth at rest or stationary, like our satellites.  Naturally it curves the space time around it.  Earth started rotating against its axis.  It is true that it is rotating with lot of velocity, in such situation, how Gravity or curvature is intact.

“If you are in a closed room on a ship sailing at a constant speed and the ride is perfectly smooth, objects behave as they would on land. There’s no physical experiment you could conduct to tell whether you’re moving or stationary (assuming you’re not peeking out of a porthole).
This is the core idea behind relativity, and is the same reason why we don’t feel our planet’s movement around the sun, or our solar system’s movement through the galaxy”.

So, in distinguishability is valid only when two things compared are equal. 

Finally, all planets including Earth are not open but closed and are having doors and windows.

Would it be fair to say that gravity is the effect of an imbalance in the local density of gravitational wave energy, i.e., Objects move in the direction of the net highest source of gravitational wave energy?

As per Newton’s inverse square law, gravity is attraction of two masses.  Both Sun and Earth attract each other, but gravitational force from the Sun deflects it and causes it to move in an elliptical orbit around the Sun. 
01 Both the planets are situated in far away places.
02 But, Sun deflects the motion of Earth and causes it to move in an elliptical orbit.
03  Sun is not near to Earth, still it deflects very motion of Earth.
04 What is the medium that aids or helps Sun to control motion of Earth.     To deflect Earth from its direction is not a simple thing and that too Earth is not near to Sun. 
05  This medium or gravity, to create pressure or force, or whatever we say attraction, to cause this action of deflection, it must be there from Sun to Earth.  It is not a remote one. 

In Einstein's theory, the presence of the sun distorts or curves the fabric of space and time. The earth then merely moves inertially in this curved spacetime around the sun. Not only Earth, but other planets also follows this curved paths.
01 Ok, Sun curved or distorted space time around it and it extended up to the end of Solar system.
02 Other planets also curves the space time around them, but it is far limited when compared to Sun.
03 How Sun curves or distorts space time up to the end of the Solar system. 
04  If Gravity is not from Sun and is coming from outside,  It is Neptune which has to control all other planets.
06  So, Sun itself is the main source of Gravity.  Sun interacts with other planets, through this medium Gravity.     
08  Sun distorted or curved space time with the help of this medium or Gravity produced by it. 
09  All other planets simply roll over or moves in this curved space or paths.
10  If Sun is also a normal planet like Earth, it can curve or distort space time up to limited area or space only.  But it extends up to the end of our solar system.  In fact it is appearing before us. 

Newton’s inverse square law, never tells you, how two masses attract each other.  For that, Newton in a true spirit accepted it.  As per Einstein, if you place, any mass, anywhere in the universe, in response it curves the space time around it.    However, from his maths, it is not clear what this curvature is.  If mass curves the space time, what is being curved.

Ok, let us compare between Sun and Earth.  It is true that both curves the space time around them.  But, though, Earth curves the space time, it is moving within the curved paths created by Sun.  Space time curved by Sun is not ordinary and it extends up to the end of our Solar system. 

But why planets are moving inertially in the curved space time.  Gravity only creates link between Sun and other planets.  It never tells planets to move.  It is the Sun which decides:

                   “I move, you move and if I don’t, you don’t”. 

It is true that planets curves the space time around them.  But without Sun there is no Gravity or medium to aid or help other planets to curve the space time.  Space fabric, within our solar system is not empty. 

When compared to other planets, Sun is different.  Sun is dilating lot of energy into the space, where as other planets are having only mass and are not dilating energy.  Energy produced by Sun is filling space fabric. 

Provided that, space time is common, Sun is an ordinary mass, to what extent or place up to which it can curve. If it curves the space time like any other planet, how it is controlling other planets.  Why Sun is the only planet creating paths to other planets.   .
 
Yes Sun is not ordinary mass, like that of other planets.  It curved the space time up to the end of Solar system.  Though other planets curves the space, it is limited and they simply follows the paths.

In normal course, space fabric is empty.  But this space fabric is filled with Sun’s energy.  It is true that energy is neither created nor destroyed.  This energy, what we term it as Gravity is spread throughout our solar system.  Other planets are not producing any energy and simply depends on Sun’s energy to curve the space time around them. 

Gravity waves are not coming from outside solar system, even if they are, its effect is far limited or nothing.  If it is everything, then, Neptune has to play key role and it has to curve entire solar system.

THINGS BEHIND EQUIVALENCE PRINCIPLE:
“This famous principle begins with the recognition that a gravitational force, as we experience it on Earth's surface ("weight"), is actually caused by space time accelerating through us on its way to the center of the Earth”.

What exactly is flowing or accelerating through us and giving weight.

“Your elevator could be moving up, down, horizontally, or in any direction at all; unless there was a change in its motion, there would be no physical effect on anything that occurred inside the elevator”.

01 If the elevator is stationary on the ground, the gravitation of the Earth still causes every object inside to accelerate downwards at 9.8 m/s2:
02 If an elevator accelerates upwards at 9.8 m/s2 will see everything within it be accelerated downward towards the floor at that same rate: 9.8 m/s2.
03    If  the same elevator decelerates, as long as the elevator was in free fall,  everything else within the elevator and the elevator itself would all be accelerated at exactly the same rate so that, inside, no influence of gravity could be detected.

Now, if you allowed a light beam from outside to enter one side of the elevator through a hole, and observed where it struck the wall on the other side. This would depend on both your velocity and acceleration relative to the outside light source. In particular:

1.   If there were no relative motion or relative acceleration between the elevator and the light source, the light beam would appear to travel straight across.
2.   If there were relative motion (velocity) but no relative acceleration, the light beam would move in a straight line, but would be displaced from going directly across.
3.   If there were relative acceleration, the light beam would follow a curved path, with the magnitude of curvature determined by the magnitude of the acceleration.

Here, from light beam experiment it is clear that gravity is changing/moving its direction when elevator accelerates. 
01  It is the elevator that is accelerating forward, but not the contents there in. 
02  Elevator is separate from the contents, including Gravity there in.
03  When the elevator is at rest or stationary.  Gravity, inside the elevator is also at rest or stationary.
04   If the elevator accelerates, gravity which is at rest or stationary, collects or concentrates at the floor.

It is true that there is Gravity within the elevator and it is proved by the laser beam experiment.  When the Elevator is on the ground, at rest, gravity packed within the elevator, surprisingly, gives you the same results as that of one on Earth.

So, there is no difference between gravity in a small region in an elevator to that of one on Earth.

It is the elevator which is accelerating but not gravity within the elevator.  Gravity within the elevator is at rest or stationary.  When the elevator accelerates, gravity at rest or stationary, floor area moves up and the gravity is collected at the floor, resulting in curved path by the laser beam.

If the same elevator decelerates, gravity at rest, concentrates at the upper area.   

Do Space warps under accelerated motion:

“Theoretically, you could be in deep space, far away from all significant mass concentrations and their gravitational influence. The rocket engine of the observer’s spaceship is firing and produces an acceleration of 9.8 meters (32 feet) per square second. This accelerated observer feels as heavy as we would feel on earth, since the gravitational acceleration with which an object on earth falls to the ground has that exact same value”.

This is another wrong assumption of Einstein.  It is true and proved by Einstein himself through laser beam experiment that there is gravity in the elevator and it behaves to that of one on the Earth.

When the elevator is on the ground, at rest, closed and if you drop the ball it fall down to the floor.  So, it is clear, irresistibly, 100% correct that Gravity can be packed within a small region. 

The cabin of the space ship is closed in a strong gravity field only.  After closing the space ship’s cabin, Mr X’s weight is 75 kgs.  As the space ship accelerates into space, there is no change in the weight of Mr.X.    As long as the space ship is accelerating, outside space time fails to inter act with the cabin.  As it reaches destination, slowly inter acts with the outside space time and equates i.e., no gravity. 

What exactly is Gravity:
“Matter tells space how to curve, and curved space tells matter how to move. That's the basic principle behind Einstein's General Relativity, which linked, for the first time, the phenomenon of gravity with that of spacetime and relativity”.

It is true that mass curves the space time.  Do all masses curves the space time equally.  No, it is not correct.  Let us compare in between Sun and Earth.  Both curves the space time. But space time curved by Sun is different and it extends up to the end of the solar system and Earth simply rolls in the curved paths created by Sun.   Basic difference is Sun is producing lot of energy and Earth is not. 

Sun is the important of source of energy to our solar system.  This energy density is the space fabric in our solar system.  So, without energy from Sun, space fabric is empty.  All other planets curves the space time around them, but it depends on the size of the mass, density of energy in the space fabric.

Gravity on a planet:
We have already discussed, Galileo’s idea, If you are in a closed room on a ship sailing at a constant speed and the ride is perfectly smooth, objects behave as they would on land.  Whether it is room of a ship or a cabin of space ship, it must be closed one.  When we compare, closed room of a ship or closed cabin of space ship to that of Earth, both must be true or otherwise they are distinguishable but not in distinguishable. 

So, Earth or any planet having gravity is not open but closed.  If it is closed, it paves way for accumulation of high density of energy.  Gravity, whether it is in the solar system or on the surface of a planet mainly depends on the energy density.

If the elevator is accelerating at 9.8m/s/s then the force we would be exerting on the floor would be twice our normal weight

Yeah, you are 100% correct.  If you are in a car, accelerating forward or applies brake, it is the problem.  Ones the ride is smooth, no such effects.
