You believe that apple is not coming down but Earth only raising upward.

No. You were talking about an elevator, not the Earth.

Mr kryptid,
At present, as per our knowledge, Gravity is nothing but, what gives us weight.  In the closed elevator also there is gravity and we are able to say this, if Mr X’s weight continues to be 75 kgs  on the earth’s surface and also in the elevator. 

If the elevator accelerates forward, we are lifting frame of the elevator only, in turn frame drags the things there in. 

Ok, suppose that you are in a car, if the car accelerates forward, remember that it is the frame that is moving forward and in turn it drags the things there in. 

From the equivalence principle it is clear that gravity can be packed and moved in a small area such as space cabin.  As long as the space ship continues its journey, space time of the cabin fails to interact with the outside space time and thus Gravity or weight continues.  Ones it reaches the destination, cabin of the space ship start interacting with outside space time and simply equates.

In the case of Car or space ship, when it accelerates forward, frame drags the things.  It is true that there is Gravity inside the car and cabin of the spaceship.  When they accelerates forward, the invisible force giving you gravity, start collecting or pooling at the bottom and it gives you equalent additional weight in the opposite direction.

If the elevator is at rest on the ground and if we pass light beam from a hole one end to the other end, it simply passes through the other hole.  Ok, if the elevator accelerates forward, there are changes in the elevator, definitely you must accept it.  When the elevator accelerates forward, light beam bends, fails to move out of the other hole.  It is proved one and is not the feeling of any body. 

Basic point is, additional weight at the bottom tells you that there is additional gravity.  So, in other words, frame of the elevator, while moving up, lifting the gravity. 

Do Gravity bends light:
In fact, there is weak gravity at the top of the elevator, where light beam is moving.  When gravity is weak, how it is bending light.  Further density of the Gravity is high at the bottom.  Bending of light is possible only when light passes through low gravity to high gravity.  But, here the thing is otherwise.  Light is not propagating in the low gravity area, but bending or moving itself from low gravity to high gravity.

It is true and proved that gravity bends light.  But, basic question is what makes or why should light move from low gravity to high gravity. 

If the elevator accelerates forward light beam accelerates downward and it is not mine idea, but proved one.

No. His mass remains at 75 kg all the time, but weight is the force he exerts on the floor, which varies as the lift accelerates and decelerates.

SPACE TIME:
As per Newton’s universe, space is flat, empty, absolute space.  He treated space as absolute entity and time always passes at the same rate. 

Hermann Minkowski developed space and time in a single formulation. This provided a stage for particles to move through the Universe  and interact with one another, but it didn't include gravity.

Einstein’s  metric tensor defines how spacetime itself is curved.  Curvature again depends on the presence of matter, energy and stresses present within it.  Curvature of space time tells how matter and energy is moving through it. As per Newton's first law an object in motion will continue in motion in straight line. But in curved spacetime  an object in motion follows a geodesic, curved line, a shortest distance.

It is true that Einstein’s space time includes gravity.  But it all depends on the presence of matter and energy.  Major difference is, can we take universe as one unit.  What about solar systems.  Why the planets exists / stays within a solar system. 

As per Einstein, gravity is nothing but curvature of space time.  Curvature of space time again depends on the presence of matter and energy.  Do matter and energy present everywhere in the universe equally.  If it is so, there is no need for solar system.   

Basic difference in between Minkowski’s space time and Einstein’s space time is that how particles travel.  In a curved space time objects travel in geodesics.

In our solar system, matter and energy is present.  What about space in between two solar systems.  Matter curves the space time only when there is energy.  For our Solar system, Sun is an important source of energy.  For the space in between two solar systems, what about source of energy.  In other words it is empty or vacuum.  Do time dilates here also.

well, right or wrong, since we do not completely understand gravity, the only thing that is left to say:
 The structure of his text was pretty easy to visualize...
 Since we are all emotive beings despise the effort, if we accept that we don't know to state we are right about the "not knowing", even that could, and most certainly is wrong... Still, easy to mind picture that scenario that he described.

On the shadow of that, could it be: Gravity is the weaker and also the strongest force divided or multiplied by the mass effect?
 If so, on those in between SS, 2d space time, gravity would be the weakest force (in that time) as much as near the horizon of the mass effect gravity would also be the strongest force (in that time)...
 If gravity were more like a tunnel then a straight line, could be the "thickness" affect it's potential?
 As on when in comparison with a straight house garden hose with a coiled fire truck hose?
 I mean the borrowing/releasing of energy at each intersection of the now "gravity submitted to mass effect" in contrast with the straight 2d one?
  Would also be possible that even gravity being the would be strongest force, a measurement of it in micro scale even on that strong environment, would say, weakest force?
 I'm not sure what I'm seeing here, I believe that the divergence has something to do with time as a multiplier and divisor, and gravity being absolute the same for both micro, macro, 2d or curved environments(spaces)...
 Sry my bad English, i'm more into mind experiments,I read more curious then enthusiast ,,,
 Also pondering on the possibility for gravity and time being two sides of the same coin, the mathematical and real sides of the same thing, being observed physically expressed as "is" (flat space time) and "is being" (during mass effect)

Mr Alex,
As rightly accepted by Newton, there is a medium, giving or causing weight on Earth, known as Gravity.  It is true that Einstein carried out number of experiments to find out "What exactly this medium is".  But, in my opinion, whenever I go by his theory or thought experiments, i feel that it is incomplete and an unfinished agenda. 

I am just trying to find out the truth, exploring the different possibilities.  I am moving with confidence, but i am not sure, whether i could present it in better way or convince others  "what exactly is gravity".

Thank you

 Almost sure that the missing piece is to start to consider outside in the known universe, extrapolating some theories.
  I'm starting reading on the possible explanation for the Golden Ratio, feels that the mathematics behind of it's why could crack that 2d space, curved space relation with gravity...
 I've always assumed that gravity is not real as a force but as potential, and time represented as XYZ(3D space) the only real expression, gravity possible being a direct result of the "water flowing inside the coiled fire hose", gravity being the "loose ends" where time, borrowing mass for the end line of it's race(it's straight line) "reached infinity", thus it starts to fade inside of itself, tunneling it's potentiality energy into motion...
  Sort of gravity represented as a firehouse coiled around earth by law due mass effect, on a rudimentary but easy to visualize approach, gravity being the shock wave produce (at each intersection the water hits the inner wall of the filing hose)...
 Somehow it, again, "just feels" open to some relation with the flat configuration of the photon...
  As if space has a minimal possible angle (pre-determinate on micro scale), or (determinate by local macro scale), and or (determinate by the nature of what shapes the universe itself (the edges)...
 I feel that the golden ratio could match this "would be spiral flat motion"(photonic)(has poles, charges and horizon) that when submitted to "observation" by other near masses, forces one to be in correlation with one another, forcing the "is flat curved straight line reaching infinity(it's own center)" into "receiving a second reference", adding a third dimension(Z) to the flat XY, turning the act simple try to reach infinity, into propagating motion, and in the process creating a spiral tunneling effect...

  Need to gather more information on the golden ratio, but there is picture of energy trying to be released from the iteration of particles alone, and it's trying to be released both as thermal radiation and light... So I must wonder that photons are the "catalyst" for gravity, more precisely... Mass being the "real" cause, and the releasing energy out of the system, into "gravity", the same one caused due mass alone, but observed wrongly from the wrong side...

 As if light was the water filing the coiled hose using it to release energy from the tank, and gravity being but a convenient "sub consequent effect", happening every time  the tunneling energy hit's the mathematical borders of the theoretical tunneling effect...
 Word salada, yeah I know, again, gravity would "only look like for the example" as the hose being submersed into water, and being filled with water too, suppose that the hose has 45° intersections, each time the water hits that curvature, gravity would be the "shockwave" propagated trough the pool...
 On space example, I accept that the water is energy, the exterior is medium(grid), and there's only particles, mass and it doubles this two as for it's own reference, the duality causing the medium(forcing it) to waste energy over those references(A and B)...
  Since there are countless references, all energy of the medium "is", and "is, will being" diminished and added to those references, if the "dot" achieves the meaning to break that "would be geometrical limitation of the curvature", it is forced to abandon macro scale, pushing all possible "energy volume available" to the exterior, creating it's own inner reference...
  A an A point, that will still interact with B and be submitted to it, but that now as it's own inner reference, so it no longers can emit energy out, only thermal... As if the coiled hose has fuse itself and it's collapsing towards infinity (it's own center), not forever or to another universe, could be the case that is simple a flux of space energy,and the releasing "is right there" as ,medium, black holes being but what we know that they are, but with one distinction, they are the "engine" that is creating the medium (space) from energy...
 A photonic sea of diffused energy waiting for reference to reshape near mass effect, and to also to be reabsorbed by the medium again....

 Sify, need first to try understand the why of golden ratio to see better, I suppose that golden ratio will re-link with particles and math... For now I guess that golden ratio is the inevitable mathematical expression of a tunneling effect local and also everywhere...
 As if black holes and inner cores ("are" would be doing without protective matter) destroy matter's own reference, and release it as medium (space), the tunneling effect being the whole galaxy on micro scale, still a macro replica of the same tunneling happening on micro scale with particles, with the only difference that particles spiral flat and black holes on 3D using themselves as reference... More simple, particles are loose ends and need to borrow energy and references to do so, their configuration is always incomplete, never reaching infinity, so the tunneling effect is more like a flow. Black holes for their turns, "cheated" offering a mass without any empty volume as inner reference, "anything" near them "assume to have reached infinity", obviously it's almost the same behavior of a planet for things can orbit them, still I'm not aiming matter, but space itself... As for space, blackholes are infinity and so it's rushed towards it, also planets are infinity, but apparently planets "push it back" in a different manner, concealing the same effect inside their mass, but away from the medium, delayed enough away from it, conveniently adverting the violent side of BH... Also seems more than convenient, planets would not be able to reform if the inner core was to BH for a few instants, meaning that they would not be able to reform themselves, is to say that new planets would be impossible to form... Sometimes "feels" designed to be like this...
 Again once we are a byproduct of the whole, is kind of inevitable to not feel that way...

 I wan't to know what lies beyond the theoretical borders, + 1 light year...
 My guess? Universe is a big galaxy, but if so, why there is a breaking limit for ratio?

Do Acceleration and gravity indistinguishable
“Imagine waking up in a spaceship, accelerating through space. Just as you’re pushed back in the seat of an accelerating car, the accelerating spaceship pushes you to the side opposite the one it’s accelerating towards. At a certain rate of acceleration, a set of scales could tell you that you weigh exactly the same as you do when you’re at home on Earth”.

Einstein realised that the effects of acceleration and gravity were indistinguishable too. This is called the equivalence principle .

This is an wonderful imagination of Einstein.  However he did not notice some of the important points.
01  It is true that cabin of the space ship is closed here on Earth only.
02  It is also true that there is Gravity in the cabin and the weight of the one of the crew Mr. “X” is 75 kgs only. There is no change in his weight, on Earth and also inside the cabin.
03  This clearly shows that, the medium or the agent causing gravity is not related to Earth or space.
04  If it is due to Earth, immediately on closing the cabin, there must be difference.  No such noticeable difference.
05  If it is a spatial flow, in such case also there must be difference, on closing the cabin of the space ship.  No such difference.

If you are in a car or cabin of the space ship accelerating forward, you will be pushed back:
01  Einstein did not pay attention to this important point.
02  If the Car or space ship accelerates forward what pushes you back.
03  It is true that the medium or gravity, giving you weight is there in the car or cabin of the space ship. 
04  Einstein forget or did not notice that, it is the frame of the car or frame of the cabin that is being pushed.  In turn, frame drags the contents i.e., human beings, contents therein including the medium causing gravity.  Initially it is the frame that moves forward and then, literally it lifts or drags the contents.
05   When the space ship accelerates forward, you will be pushed back, why and what pushes you back.  Einstein pointed out this important point, but left it.  When the space ship accelerates forward, initially, the medium or agent causing gravity is at rest or stationary.  It is the frame that lifts it and in turn,  medium start collecting at the bottom and gives you additional weight.

It clearly throws light on some of the important qualities of this medium:
01  It is true that there is gravity inside the cabin of the space ship when closed. 
02  When the space ship accelerates forward, cabin drags the contents, resulting in additional concentration of gravity at the bottom.
03  This is evident when you are pushed back.
04  So, concentration or density of this medium decides gravity at a place.  When the cabin is locked,  gravity spread uniformly. As the space ship accelerates forward, medium density at the bottom increases resulting in additional gravity.
05  But, one’s the space ship attains velocity, this medium again adjusts uniformly. 
06  When the space ship accelerates forward, gravity collects at the bottom shows that this medium itself carry weight.  This is the reason, density of this medium is high on earth’s surface. 
07  If the density of this medium at a place increases it results in most curved or increase of gravity.

Do Acceleration creates / generates Gravity:
This is another wrong assumption of Einstein. 
01  It is true that cabin of the space ship is packed in a strong gravity field only.
02  It is also proved that there is Gravity in the closed cabin.
03  When space ship accelerates forward, no additional or new gravity is  generated in the cabin.

Basic doubt of Einstein is that:
01  The space ship is far away from gravitational mass, still there is Gravity. 
02  Einstein thought that acceleration is warping the space time.
03  That is untrue.  There is no proof that acceleration warping or generating gravity. If that is true, there must be change in the gravity field inside the cabin of the space ship.  No such thing hinted or found.
04  If the cabin of the space ship is locked in a non-gravity field and if acceleration generates or creates gravity, then we can say that  Einstein is 100% correct.

The cabin of the space ship is closed in a gravity field and there is gravity in the cabin.  As the space ship accelerates forward, cabin of the space ship fails to interact with the space time and thus Gravity is intact.  One’s the acceleration stops or engine stops, space time of the cabin interacts with the outside space time and this medium simply neutralizes.

It is clear, when the space ship accelerates forward, gravity collecting at the bottom shows that the density of the medium is high and it also carry weight. 
01  It is true that there is gravity inside the cabin of the space ship and Mr “X’s” weight continues to be 75 Kgs only.
02  So, Gravity is not due to the attraction of mass or flow of space time.  Without relevance to anything, it is present on Earth.
03  The density or presence of this medium itself is gravity.
04  Generally, this medium itself is heavier, low concentration or density, no gravity, from medium concentration onwards gravity develops.
05  It is moving towards Earth, not due to attraction but, since it is heavier.
06  As said by Einstein it is also matter blind.
07  Since this medium carry weight, continuously it exerts pressure on the existing medium or gravity present against Earth’s surface, it appears that it is a spatial flow.

About ‘Free fall”:
This is a game changer to Einstein relativity and Einstein himself also proclaimed it as “happiest thought” of his life. 
It is 100% correct and there is no doubt about that one.  However, let us analyze the same in our context.
01  The medium, giving you weight is already present in the space time of the Earth.
02  Since it is heavier, it continuously exerts pressure against the medium that is already present on Earth’s surface.
03  When a person dives in from higher altitude, he moves along with the medium and thus experience no weight.
04  It is not a spatial flow.  But its source is outside only. 
05  It appears that Earth is having doors and windows and they are not allowing free movement of this medium. 
06  When the space ship accelerates, gravity concentration at the bottom increases and pushes you back.  But as the space ship attains velocity, this medium or gravity neutralizes. 

So, Finally climate is paving way for additional concentration of this medium or gravity.

you're suggesting that the medium reads dense matter(earth) as a "hole" on it's fabric, and thus constantly trying to fill it... Electromagnetic forces/atomic forces, fight back, or more likely, use this medium attempt to their own benefit, not being able to collapse, they start to spin, not from themselves as their properties are, but their motion a physical representation of this medium?
 Something like that?

If so, gravity should be greater at the points where the extraction of energy is greater, planets, heavy particles, and blackholes?
 Would this medium be "falling" (accelerating faster in time) to close such "gaps" within it's tissue?

Or perhaps, but a complex geometrical shape for empty volume in occurrence in between A-B? Could this medium be ever present as a energy grid but diluted due universal expansion(acceleration)? as if everything stops moving, the nature of the medium would be physically revealed, as everything would simple instantly be undone due absolute heat...  Could be the acceleration s "draining" this medium reducing temperatures, as masses or point's the medium sees as infinity for it to collapse(fill), heat up due lack of acceleration?

I'm wondering what theoretically happens to space on black holes?
, geometry or thermal? As if the neutron star is not a neutron star at all, but a pace where the universal acceleration can no longer reach. A center away from space physical interaction, due geometry space has become impossible to touch(reach) that center... But instead of spinning neutron star, space is sniping along with the matter it is digesting, but inside the center, nothing but a hole, direct access to this medium...  It would be something if the medium proved to b true, and owner of all energy, and particles but different scales in time producing different energy frequencies... So anything that we tough that has ever spin or had properties would be just borrowing...

Any idea of the nature of this medium? Electrical?

 If universe as we see would be just as a cabin accelerating over this medium, and if true that universe originated from a single point accelerating expanding over this medium. Would make sense (maybe just convenience) that anything on the reverse would give access to the medium as it is... Unobservable and only possible delayed apart from acceleration, as much as for the traveling ship?

Ok, we will discuss about medium at a later date.  Basically it is equivalence principle, which is base for general relativity and Gravity to be decided first.

"An elevator that 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. When you're in a vehicle that rapidly accelerates (and you feel yourself pushed back into your seat) or decelerates (that thrusts you forward), you're experiencing similar effects to what someone inside the accelerating elevator will feel".

It is true that it is the elevator accelerating forward.  But what is accelerating downwards.  Simply saying that it is due to  Newton's second law, F=ma is incorrect.  When the elevator accelerates forward, something is accelerating downwards, pushing you in opposite direction. 

01  It is true that there is Gravity inside the elevator and Mr.'X's weight is 75 kgs.
02  There is every need to understand that we are moving frame only.  For better understanding, take the example that you are in a car.  You are moving the frame of the car and in turn frame drags the contents there in including yourselves.
03  When the car is at rest or stationary, gravity or medium causing gravity is spread uniformly.
04  As the car accelerates forward, the medium, giving you weight continues to be at rest only.
05  As the car moves forward, things within the car faces additional medium, and thus boosting of gravity at the edges.
06  Additional gravity at the edges, pushes you backward.
07  One's the car attains  velocity, things comes to normal.

Gravity acts on mass, to lower the space that is occupied by the mass. This is true for both non relativistic, as well as  relativistic space. The apple falls to the earth to further compact the mass, reducing the total space requirement, While enough collection of mass compaction will case space to compact even further due to relativity.

This contraction of space, due to mass and gravity, heads local space in the direction of the speed of light reference. In the speed of light reference, space becomes a point. Gravity moves mass in the general direction of the speed of light reference.This is because the speed of light reference is the ground state of the universe; lowest potential.

Another observation with gravity is although non relativistic space; higher density, and relativistic space both compact; space-time contraction, the time aspect of space-time behaves differently when acted upon by gravity.

The relativistic time will slow, but the non relativistic expressions of time; matter based transitional  frequencies will speed up. The mass of the sun will cause the space within the core of the sun to slow time, via space-time. However the matter in the core although lowering space gets hotter and moves and vibrates faster. Gravity impacts space consistently one way,; compaction, but gravity  impacts time in two opposing ways. The units of acceleration due to gravity is d/t/t or is one part distance and two parts time.

This odd ball aspect of time, which differs from the direction of non relativistic space and relativistic space-time, is connected to entropy. The material heat and speeding up of vibrational time causes phase changes that increase complexity. This will resist the movement of gravity toward the ground state. A burning star is fluffier within space because of the speeding up aspect of non relativistic time and how time integrates with space. This aspect of gravity is often left out of the analysis, even though gravity creates the affect. The solar wind adds apace to the sun.

We live in a universe that is undergoing an accelerated expansion. This is one part distance and three parts time. d/t/t/t. I call this time-space. Time is not one thing but have three separate parts, two of which are provided by gravity.

0-D time is a point in time. 1-D time is a time line, such as velocity; SR. 2-D time is an acceleration such as due to gravity; GR, while 3-D time is an acceleration of an acceleration. In time-space, time becomes the 3-D coordinate system that measures three layers of action within radial space. Space-time is (x,y,z,t ), while time-space is( t1, t2, t3, r)  If we combine these space-time becomes  6-D or (x,y,z,t1,t2,t3).This tells us exact position in space as well as the total time potential in 3-D time. Modern physics does not do very much with t3, but t3 can add entropy and randomness leading to furthering complexity. If used in conjunction with t1 and t2 provided by gravity, complexity can mean improvements and not just random change.

Gravity acts on mass, to lower the space that is occupied by the mass. This is true for both non relativistic, as well as  relativistic space. The apple falls to the earth to further compact the mass, reducing the total space requirement, While enough collection of mass compaction will case space to compact even further due to relativity.

This contraction of space, due to mass and gravity, heads local space in the direction of the speed of light reference. In the speed of light reference, space becomes a point. Gravity moves mass in the general direction of the speed of light reference.This is because the speed of light reference is the ground state of the universe; lowest potential.

Another observation with gravity is although non relativistic space; higher density, and relativistic space both compact; space-time contraction, the time aspect of space-time behaves differently when acted upon by gravity.
Effects of Gravity, OK.
But, "what exactly is gravity".

“An elevator that 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”.

Ok, if it accelerates downward, relatively everything within it moves in opposite direction i.e., upward direction.

When the Elevator accelerates upward, gravity is moving down and if the elevator accelerates downward, gravity is moving upward.  Here Gravity or the medium is not moving up or down, but it is the frame that lifts it, leading to additional concentration of gravity in opposite direction.

The object or the medium, giving you weight is changing its direction when the elevator moves up or down.

To change direction, the object or the medium must carry weight by itself.  If it is lighter,  then,  there is no scope for its additional concentration or boosting at a place.  So, its very presence itself is the Gravity.  It need not exert force or pressure against you, very presence itself is the gravity. 

You are experiencing weight, since you are living in this gravity field.  If you move away from this field, simply, there is no gravity at all. 

This object or medium or gravity is heavier and therefore its concentration is high on the surface of the Earth and diminishes as we move up.

01  It is true that there is Gravity inside the elevator and Mr.'X's weight is 75 kgs.
This "inside"/ "outside" restrictions is what do not match the picture here...
Shouldn't be such a thing.
 Unless, on a short version, gravity on space is electromagnetic based.
 And "our" gravity here, more atmospheric related.
 
 What I mean if there is an inside and or outside something, and that truth is unrelated with gravity.
 Gravity could be derivative from geometrical shapes, as if matter tied together "offers" a "minimal" margin, volume for "medium", only that on this case, medium would be the effect caused due density...
 Trying to picture, that anything "dense" enough to be away from "medium" and or "not submitted to it by shape, would be "gravity less"
 As a _-_- - - - - - - - - - - line would "inevitably be" submitted to "medium" either by existence or by possibility.
 While a dot configuration, or perhaps each (-) individual dot, smallest most dense structures, would not...

 Not sure yet, thought experimentation do not account for math...

1-One is inside a box submersed into water.
2-The box is empy and it's wall have the smallest possible distances in between each hole.
3-The box have thickness granted "in time" only due the fact that the box is accelerating"
4-The box doesn't consider to be accelerating on it's own, the medium(pool) is the thing fluxing around the box.
5-Accelerating only from A in comparison to B.
6-This acceleration not as a straight line, more like a flux, as the water is constantly "rushing" to close the hole that the box represents on it's 2d plane.
7-Medium(water) into trying to fall over the "elevator" collides with many "micro elevators"(particles)/Matter.
8-The collisions within the different angles and interacting with each others, permeate, mixing totterer, to the point the gravity "inside"(while there is none) is taking more "time" to rush out of the box, and what was other wise spread, a sphere fluxing from inside out without a single broken fold, become a more flat shape (disk).
9- The horizon starts to add a 4D dimension and starts to organised all the waves together on a 2d plane.
10- On the act of doing so, the medium is also blended and elongated (the geometry of it) and from box starts to become rounded...
11- I mean the new 4D horizon is forming on the present moment in time that the box is moving away from it, due "external sources", so I assume the horizon keeps constantly reforming at the rate the elevator is being lifted.
 An "incomplete" sphere(disk for a 2d plane) while having it's center relocated in time (y) would behave more like a spiral (interference on the geometry/medium), elevator is squared and fixed, thus it's "apart" from what's truly going on there"
A drop of Rain would be more precise, but too flexible, plasma would be the best thing to observe, as for what i'm suggesting is likely not be seeing, by impossibility, as if the act of trying it would ruin it..

 I guess the image is, the interaction in between different particles, and their configurations, force medium to "fill the gap" as it reads it as a 3d object now that it's shaped, and by the "time" the tick hit's the designated spot, it's unable to locate it, still the attempt remained, as a "loose end wave/dot" as a wave inside an pool, ever propagating "by chance" not by the existence of anything in witch into propagate to...

 Has for now: "the configuration of matter" create loose ends within the medium, dot particles as while the frame they occur, and wave on the previous frame, also waves on the future frame, past and future being only relevant from the angle one is looking, wouldn't matter if the direction as outside in, and is inside out simultaneously, or very quick updated...
 if nothing else, I believe would be: Medium takes a certain amount of "micro geometrical distances" into interacting with the elevator, as this happens, the "would be inner box" starts to behave like a 2d plane, and the box itself due drag "in time" starts to fluctuate (take a ride) on the bouncing wave itself is causing (against the moving water)...

 Not sure... I feel like about 100% the only problem there is the "inside/outside" perception...

It is true that equivalence principle is the base for "what exactly is gravity".  But without having sufficient or correct idea on 'what exactly is gravity', it is like constructing a beautiful house without base. 

Mr Alex, tell me, can this geometry gives us a perfect idea on gravity.  Ok,  famous notation, "matter tells space time how to curve and curved space time tells matter how move".    How matter tells space time to curve.  What is being curved.  How this curved space time influences matter in turn. 

It is true that it is a change from Newton's inverse square law.  We are discussing, black holes in depth.  Further it is a big topic, measuring event horizon, can light escapes, and what happens if you dives into a black hole.  We also discuss about expansion or contraction of universe in a big way.

But, in exact terms, we don't know, "what exactly is giving you weight" on this Earth.

When it is nor clear, we follow, Newton's inverse square law.

"matter tells space time how to curve and curved space time tells matter how move"

 Space is but empty volume, feels more geometrical and only exist in our minds, while observing A-B-Z.
 Collide every matter together, no space no more, still...
I understand what you mean, and it's truth, are but ideas, I'm, based o your posts, starting to consider gravity as "potential", as much as if earth and Jupiter were one and the same, as the space in between them just empty volume, permeated by "wherever" from time to time...
  If there's a necessity for another external factor to fill the gap, maybe by convenience, I'd blame our senses, left right, Y,X, from here to there or there to somewhere else, as distinct things...
  Gravity is interference wouldn't also suffice... (on what?)
 If one is the same, and there's no room for gravity, gravity would have always being space as it is, on a miss interpretation that it must be something, cause we may have named it... the speed of a shadow
 and all that "gravity" does, is but other forces permeating to empty volume.

 Can't answer. Still I got the point, and is right, i'm afraid the whole line would be wrong, for if everything is possible we would have already, unless we do...
 Many users here and there, almost everyone has a "possible" way how gravity would be, non is correct... makes wonder
Gravity as a derivation of other forces, a "potential" into be, something that can't be everlasting a moment in time...
 Only thing comes to mind in terms of "Sustaining an impossibility" would be geometrical and requiring time so to exist...
 Something that could be, will become, but never is, should be potential, a reaction of something that is...

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?

Frequency is 1/time. Atomic clocks, for example, depend on the precise frequency of specific atoms to set the pace of time. These transitional frequencies set a tempo for time in terms of transitional states. These " natural second hands", so to speak, speed up in the center of a star, even though space-time is slowing in time due to GR. There are two difference type of clocks, one for motion and the other for phase changes and entropy. Gravity does both. Space-Time alone tells us nothing of fusion, since you need the other clock for that. Gravity does both.

Another observation with gravity is although non relativistic space; higher density, and relativistic space both compact; space-time contraction, the time aspect of space-time behaves differently when acted upon by gravity.
Effects of Gravity, OK.
But, "what exactly is gravity". 
 

In the lab, matter and antimatter pairs form only at highest energies. If we started with radio waves, then microwaves, then visible light, then UV, then x-rays, then gamma rays, matter and anti-matter pairs will not appear until gamma and beyond. Matter and mass appear at the upper limits of energy. Matter and mass exist at the energy ceiling of the universe, while all energy photons less than gamma, which is most of our universe, are the energy floor and walls.

Our universe is currently matter with very little anti-matter. Without anti-matter to help matter lower potential in a direct way; annihilation, matter has to lower potential, from the ceiling, in a piecemeal fashion. Gravity is one way to do this. If antimatter was still plentiful, as matter, gravity would not be needed to lower potential. Matter and antimatter would find each other using unified forces.

When mass clusters due to gravity, local spacetime contracts. As we add more and more mass contraction moves the local space-time reference toward the speed of light reference. At the speed of light, reference becomes a point-instant. The black hole is close to this. The speed of light reference is the floor, and  mass cannot go there since it contains too much potential. 

Mass, via gravity, is trying to return to the speed of light reference; convert back to energy. However, mass cannot reach that reference, since anti-matter is not there. However, as gravity contracts space-time, the frequency aspect of time is getting faster and faster. The goal of this secondary time is to increase frequency to gamma and beyond, hoping to catalyze itself with new matter and antimatter. This usually falls short, but does burn some mass back to energy via fusion. There are cases where this does occur; boom!

If we look at matter and anti matter, they are equal and opposite. Positive and negative charge are also equal and opposite. To give one a feel for the impact of the loss of anti-matter, say instead of losing antimatter, we lost negative charge.. Now we have a mono-pole of just positive charge.

If we restrict space, so the positive charge cannot expand to lower potential, the charge repulsion, that was once neutralized by negative charge, is now unopposed. This will heat up the positive charge making it even more potent in terms of total potential. The mono-pole will now have both energies but in a new way. Energy is conserved. This does not increase positive charge, but it does create heat for entropy to act. Now we get inflation and the second law appears.
