New Theories / Re: What exactly is gravity?

PRIMARY EVIDENCE OF GRAVITY:

Well, it is known fact that, when Newton was sitting beneath an apple tree, an apple hit his head.  Newton started thinking, why don’t apple remain then and there in the tree, what force is pulling it.
 
Soon, he realized that the same force that pulled apple to ground is also keeping the planets in their position. It is said that it is the base for inverse square law.

I think it is one of the primary evidence, that one can observe or see them directly on Earth.

Another important evidence that one can see or observe is “TIDES”.  Tides are naturally occurring rise and fall in the level of water in oceans, bays, gulfs and inlets. They are the direct result of the moon's gravitational pull on earth. The moon's gravity creates two bulges in earth's oceans.

It is true, tides are due to gravitational pull of Moon on Earth.  If we take Newton’s inverse square law, it is due to attraction of masses.  Here, there is no scope in change of mass, Earth and Moon and it is the distance that plays key role.  When they are nearest to each other, the moon is in the point of its orbit called the perigee, and its pull on Earth is the strongest.

The moon's gravity reaches all parts of Earth, but its pull only noticeably affects large bodies of water, resulting in tides.

When the moon is at its full or new moon phase, high tides are at their highest, while low tides are lower than usual. Called spring tides, these tides occur when the sun, moon and the Earth all line up.

Einstein’s 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”.


Ok, Earth is a huge mass, it curved or distorted space time.  Similarly Moon also curved or distorted space time.  Moon is only moving inertially in the curved space time distorted by Earth.

Einstein’s general relativity, never gives us an idea or tells us how mass curves the space time and what exactly is being curved.  So, Einstein’s theory is incomplete and he left gravity an unfinished agenda.

Well, it is known fact that Newton’s inverse square law is incorrect.  Yet we are following it because General relativity is incomplete. 

In the words of Newton:
“Gravity must be caused by an agent acting constantly according to certain laws; but whether this agent be material or immaterial, I have left to the consideration of my readers”.

Yes, whatever Newton’s assumption is 100% correct.  Tides are being caused by an agent or medium, which is influencing curved space time.  Ok, let us analyse it in detail. 

Leaving other things, let us take it as New moon or full moon day:

Event 1:

Let us imagine that  three planets, Sun, Earth and Moon  are at rest or stationary.  These planets are not rotating or going round the Sun.  Since these planets are in straight line energy moves straightly.  Energy from the Sun hits gravity of Moon and charges it.  Once again moon reflects it towards the Earth.  It is a continuous process.  In turn this energy, once again charges gravity of Earth.

Here it all depends on mass size, if the size is big enough, more energy is reflected back into space. Here, as assumed by us all the three planets are at rest or stationary. 

As assumed by Einstein, for an observer it is an event 1. 

At this event,  energy from Sun moves straight, in turn moon reflects it directly and it only charges gravity field of Earth and there is no scope for tides.

Let us move to event 2:

Now Sun started rotating against its axis and in turn it dragged the gravity field surrounding it.  If Sun started rotating means, it is not mass alone but also strong gravity field adjacent to its space time.   Particles start coming out with certain amount of force or pressure.  Electromagnetic waves start moving in 180 degree angle.  Energy start flowing in the space time.  They hit the curved space time of the planets in an angular manner and the curved space time gains momentum and in turn it drags the planet. 

I think, this is what Einstein said, mass tells space time how to curves the curved  space time tells mass how to move.  This is wonderful quotation, indeed, but lack of explanation. 

Galileo’s indistinguishability, clearly tells us that all the planets are not open but closed.  So they absorb most of these effects. 

TIDAL WAVES:
In normal course there is no scope for any tidal waves.  Since our planet is a closed one, it neutralizes all the solar impacts.

However,  moon is rotating near to the Earth, it reflects back electromagnetic waves with certain amount of extra or additional force or pressure.   As Earth is closed one, most of the effect is absorbed and small effect is passed on to the space time of the Earth.  Naturally it creates pressure on the nature. 

During New or full moon day, most of the energy is passed on to the Earth.  It will be having its impact on the gravity of the Earth and in turn on the nature.  Water at the centre absorbs the effect, however at the edges, density of the water is weak and it raises. 

As assumed or thought by Newton, there is an agent working constantly and creating pressure or force on water and it is the “energy”.

Tidal waves are another evidence that one can observe or notice directly.

It is also proved that if the space ship accelerates or decelerates, something is changing.  This is nothing but gravity field only. 

As the space ship accelerates, it lifts the cabin, and in turn cabin lifts the things there in.  The gravity field, at rest or stationary start concentrating at the bottom, resulting in additional potential energy or gravity, which gives additional weight to things at the bottom.

As thought or assumed by Newton, gravity is caused by an agent, energy, which is acting continuously on all the planets. 

Tidal waves proves this, what else proof is need.

Well, even today, gravity is mysterious one and we are not in a position to say this is “what exactly is gravity”. 

Ok, suppose if you pick up an object and throw it with little momentum it will come down to Earth only.  As assumed by Newton if you threw it with too much momentum, it will speed away from the planet, start beginning its journey around the Earth, along with moon.  By the time of Newton science is not developed.  Newton realized that the same invisible force that gives you weight on earth is also affecting the movements of moon.  He has drawn these conclusions taking some of the facts, moon orbiting Earth. 

“Albert Einstein proposed that massive objects warp and curve the universe, resulting in other objects moving on or orbiting along those curves—and that this is what we experience as gravity.

In Einstein’s view, gravity is far from a static, unchanging force—it is a fundamental part of the structure of the universe, which curves and twists and ripples as objects move and rotate and jostle about”.

By the time of Einstein science developed a lot and clear picture on functioning of our solar system came out.  All the planets are moving in circular orbit, exactly in their paths around the Sun. 

So, Einstein predicted that Sun curved or distorted or created paths around it and in this paths all other planets are moving.   

Further,  Einstein knew that there are sub-paths created by masses in a curved path, they are just moving.  For example, Earth is a huge mass and it distorted or curved space time around it and moon is just making its journey in this curved path.

It is true that Sun distorted or curved the space time around it.  We knew this, since planets are moving in this paths. 

However, as per my knowledge goes, Einstein tensors are not clear on how mass distort or curve space time or area up to which it distort them.  It is also not clear, what is being curved.

But, Einstein’s thought experiments are wonderful and beyond imagination of an ordinary brain. 

He equated “acceleration to Gravity as indistinguishable”.  Well, space cabin is locked here on the surface of the Earth where there is strong gravity field.  As the space ship accelerates, there is no sign of  increase or decrease of gravity. Only difference is, as long as the space ship accelerates, there is gravity inside the cabin of the space ship, why?,  Except this, there is no valid question or solution to this by Einstein. 

But, by this, we can draw number of wonderful conclusions.  It is true that there is strong gravity on this Earth.  Cabin of the space ship is blocked here in this gravity field only.  So, it tells us:
01  A part of the gravity can be packed in a small area such as cabin.
02  Even if we take this as medium, quantity packed in a small area such as cabin is very small.
03  In spite of quantity being small, it gives same weight.
04  This is in distinguishability.
05  As the space ship accelerates and moves into deep space,  small quantity of medium or gravity, packed in a small area such as cabin, remains intact.   

Further it is also proved that:
If the space ship accelerates or decelerates, something is moving or changing in the space cabin, pushing the objects in the opposite side.

Here also, it is the space ship that is accelerating forward and in turn, it lifts the cabin and in turn cabin lifts the contents therein.  It is interlinked to each other.   

As the cabin moves forward, gravity which is at rest, remains then and there, but the medium density at the bottom increases, resulting in additional gravity at the bottom.

Einstein’s equation “acceleration to gravity” clearly tells us that gravity is not attraction of masses and at the same time is not spatial flow, but is a field present on the Earth.

Only thing, we have to explore how this field came into existence and “what exactly this field is”.

Does equivalence principle, equated properly:

Well, it is true that Galileo Galilei’s equivalence is the base for relativity.  But here we are not analyzing what galileo said and mostly concentrating on what Einstein said. 

Einstein says that there is also indistinguishability, as assumed by Galileo in the case of smooth sailing ship, in a closed cabin of space ship.  That is right. 

But, what Galileo said, in a closed room, if the sailing is smooth, things are behaving as if on land.  This is the core idea. 

Here basically indistinguishability is in between:

Closed room of smooth sailing ship  =  Earth.

But, Einstein left this indistinguishability.  His idea is that, there is also indistinguishability in closed room of a space ship to Earth.  Things in the closed room of a space ship, if the acceleration is smooth, behaves as if on land.

There is no doubt about, what Einstein said.

Basically, Galileo’s indistinguishability is different one.   Things in a closed room of a ship, if the sailing is smooth, behaves as if on land.  If there is a porthole, matter is different. 

What Galileo’s idea tells us, Similar to that of smooth sailing ship, Earth is also rotating with lot of velocity.  Like a closed room of a ship, Earth is also closed one.  That is why, there is indistinguishability.

This is the reason why we don’t feel our planet’s rotation and also revolution around the sun, or our solar system’s movement through the galaxy.

Does equivalence principle, equated properly:

Galileo Galilei’s wrote this in 1632 even before Newton has published his 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 a simple insight into what is happening in his surroundings. 
01  You must be in a closed room of a ship and no porthole.
02  The ship must move at constant speed and smoothly.

Basic idea of Galileo is that, if the room is closed and if the ride of the ship is smooth, inside room, you will get the feeling as if on land.  This is an excellent idea.

Einstein’s equivalence is an extension to Galileo Galilei’s, relative motion of objects.

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

01  The cabin of the space ship must be closed and there are no windows to look or opened.
02  Spaceship must move at constant speed and smoothly.

If the cabin of the spaceship is closed and  accelerates smoothly, in such condition, you will get the feeling as if on land.

This is the equivalence principle and it tells indistinguishability between a person inside the room of a  smooth sailing ship and  to a person in the cabin of the ship accelerating smoothly.  Further, in both the cases,  the person must be in a closed room and the sailing or acceleration must be smooth, in such condition, the person inside the ship or space ship gets the feeling as if on land.  This is equivalence principle.

But, here, Einstein simply added effects of acceleration to Gravity.  This is separate one, and how it tells indistinguishability.  For this, there is no equivalence at all.  Einstein’s idea is that, the space ship is far away from all huge masses, in deep space, still there is gravity inside the cabin of the space ship, why?.  It is only answer to this question, there is no indistinguishability or comparison to anything.

Galileo’s idea is excellent and extraordinary.   In a closed room, if the ship is sailing smoothly, ‘I am getting the feeling as if on land’.

Earth is also moving with constant velocity, but we are not getting this feeling, since it is a closed one.   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.

Einstein’s idea, effects of acceleration to Gravity is different one.  It is true that the cabin of the space ship is locked in a gravity field.  One of the crew, whose weight is 75 kgs on Earth, continues to be the same even after closing the cabin of the space ship.  As the space ship accelerates into deep space, there is no change, increase or decrease in the weight of the person inside cabin.

Experiments conducted inside the spaceship during acceleration and deceleration would show that something’s changing.  It is nothing but gravity field only.  While accelerating or decelerating the space ship, you are only moving the frame and in turn gravity field is changing its position.  While changing its position, gravity is pushing you in opposite direction.  If the space ship accelerates forward, gravity start collecting at the bottom. It shows that the “Gravity field” itself is heavier.  Its very presence i.e., density on Earth or any mass, decides gravity on that planet. 

Gravity is not what we are thinking.

Well, it is true that Light is composed of electromagnetic waves, or as a collection particles, according to the wave-particle duality nature of light.  This spreading of light is known as 'divergence'.  A narrower beam of light spreads out more than a wider beam.

It is known fact that Gravity bends light and it is proved one.  When it bends light, in a strong gravity field such as Earth, if light particles start moving out,  it also aids in divergence or propagation.  We have only invented method of conversion and Gravity is aiding in propagation.

Light travels faster in vacuum than any other medium. This is because there is no obstruction in vacuum for the propagation of light and thus, the refractive index of vacuum is the lowest.  Well, it is true that gravity is matter blind.  While creating vacuum, we have removed air and in turn all particles moves out along with air.  So, without particles, gravity will not stay and moves out freely. 

So, finally,  without presence of particles, spread of gravity is weak.  In turn it affects propagation of light.

I mean, if not clear:
 "WHAT would be the mathematical/geometrical "possibilities" if universal expansion was to reach the impossible edge of the universe, would it be forced to bend itself by splitting and multiplying volume, rules, wherever, so to "turn around"and reach infinity again?

Einstein has taken us to a different world.  It is true, it is a big topic, expansion or contraction of universe.  In my view, first we must be in a position to say, what exactly is gravity on Earth.  Further, we must have a perfect idea on functioning of our solar system.  But, here, un-certainity prevails and for all practical purposes we are taking Newtons inverse square law, which, we know, is incorrect.

Then why things fall?
 It would also be answered by the same answer that explain, not what gravity is, also not what gravity isn't.
 It would be answered by explanation that excludes it's very existence from the board.

It is true that apple is falling to the ground.  Yes, without saying or knowing the force that is pulling or pushing the apple to the ground, any idea or theory on Gravity is waste or incomplete.

Well, to find out this truth Einstein carried out number of experiments and his thought experiments or beyond imagination.  However, what i am saying, i am not finding fault with his experiments, simply exploring other possibilities.

Einstein's equivalence principle is incorrect.  His ideas are great, but he has taken wrong notions, which, further diverted leading to "what exactly is gravity" incomplete and incorrect. 

Space time is an important topic, which, i am sure, decides what exactly is causing apple to fall to the ground.  Here, Einstein's idea is correct, but he left it incomplete, without giving or describing all the factors of spacetime. 

It is here that i am struggling hard.  As per my knowledge goes, if we place any mass, anywhere in the universe it will curve the space time around it.  As long as the mass is not placed, it is a 2d space and when the mass is placed, it is converted to 3d space.  How it is possible?.

Even on Earth, the gravity, giving you weight is also doing wonders.  It is true that it is giving weight.  We know this, since Newton told us.  When it gives you, so much of weight, how can we say that it is not influencing other masses and our daily activities..   

If this myth is unleashed, i am sure, several theories are to be re-written. 

To unleash this, we have to re-set our mind set.  Let us take Newton or Einstein's theories as base and explore further to achieve this farthest mission.

    What this space fabric consists of.


One doesn't have to consider space-time as being made of anything other than space and time in order for relativity to work.

When we talk of anything, it must be specific or otherwise the theory is incomplete or insufficient.

"Matter tells space time how to curve and curved space time tells how to move".   Matter tells what to curve or how this curved space time interacts with matter and tells it to move. 

In general relativity,  gravity is described in terms of the curvature of space time. For example, imagine a sheet of rubber with grid lines like graph paper, suspended horizontally so that it forms a flat surface.  With no weight on it, the grid has straight lines and right angles, corresponding to the "flat space" of Euclidean geometry.
.
If you place a ball on the surface, the rubber sheet stretches around it. The curvature of the grid increases as it gets closer to the ball. This corresponds to the curvature of space-time near a massive object.

If the bowling ball is placed at the centre of the rubber sheet, it will curve or distort the sheet.  If we roll a marble piece in this curved path, it will go round the bowling ball.

This description is ok for non-Euclidean geometry. 

Well, it is true that curved space time is nothing but Gravity. We know that Gravity is keeping the planets in orbit around the sun and also is keeping the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides.  Einstein also proposed number of effects, time dilation, light bending i.e.,

Without complete description of what is working like space fabric, being curved by mass, theory will not go further, ends at the one stage or the other.  This is what happening and we are taking Newton’s inverse square law as base.

This is the reason, still “what exactly is gravity” a mysterious one.

The curvature of space is directly proportional to the mass.

Here, basic point is "what exactly this curvature is".  It is true that mass and the space fabric is different.  Mass curves or distorts the space fabric.  What this space fabric consists of.  Basic difference in between 2d space time to 3d space time.  Without this information, talking, anything about mass curving or distorting space time is immaterial.

No. It's just that you can't distinguish acceleration in an elevator from being stationary on a planet's surface. They are not literally 100% the same thing. In order to feel "gravity" in an elevator in free space, you have to be accelerating. You don't have to move at all to feel gravity on the surface of a planet.

I think you are in out of mood.  I am talking about free fall in a gravity field and the free fall in space.  But you are talking about acceleration and gravity.

Free fall, Elevator and space station:

Let us Imagine that you are in a closed elevator and it is accelerating downwards. 
01  It is true that you are in a gravity field.
02  You are  moving along with the elevator, in other words you are in a free fall.
03  Though you are in a strong gravity field, you are escaping gravity.
04  Here, all other objects moving along with you are also in free fall.

Now imagine that you are in an international space station:
01  The space station along with you is in free fall.
02  It is moving, in an weightless condition around the Earth.

Now we are comparing free fall in an elevator to free fall in a space station.  Is it correct?. 
01  “Free fall” in an elevator is in a gravity field.
02  Here, “free fall” is escaping gravity.
03  Besides that, elevator is moving towards the centre of the Earth.
04  But the space station is already in a gravity free place.
05  When there is no gravity, what is there escaping.
06 Further the space station is moving around the Earth.

So, comparison is incorrect.  Basic question is?.
What makes the space station to move along with Earth is important.  There is no free fall here.  There is something, which is causing Earth to move is also causing space station to go round the Earth.

What is the basic difference in between, space time curved by Sun and other planets.

The Sun has far, far more mass than the planets. That's why the planets orbit it and not the other way around.

Is it mass alone, not the curved space time.

New Theories / Re: What exactly is gravity?

« on: 15/08/2020 16:09:29 »

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.

If mass curves or distorts the space time, it must be clear, what is being curved or distorted and the area or place up to which to curves or distorts. 

Science developed a lot and we know that there are 9 planets in our solar system.  Well, it is true that all the planets curves the space time around them, i.e., Gravity.  Sun is at the centre and other planets are rotating against their axis and also going round the Sun. 

If each planet curves or distort the space time around them, they must act independently and there is no need for them to go around the Sun.  But it is not happening so.  Sun curved or distorted space time up to the end of the solar system and these planets are only existing or curving the space time already curved or distorted by Sun.  What is the basic difference in between, space time curved by Sun and other planets. 

So, we can take Sun as the independent planet and other planets as dependent.  Here important point is what makes Sun to be independent.  If this problem is resolved,  it gives clear idea on "what exactly is gravity".

Place a mass down anywhere in the Universe, and in turn it curves or distorts space time around them, which is known as gravity.  It must be clear that what is being curved or distorted.  We don’t know what space fabric consists of. 

Need not worry, if there is no answer we go for Newton’s inverse square law, which opts or fits in every aspect.  It is true that, Newton’s theory is incorrect, yet we follow it, as Einstein’s theory is incomplete.

Mass curving the space time is different to Gravity.  Though each and every mass curves the space time, we cannot take it as gravity.

Mr Kryptid,

Let me share, some of the incidents / things happened in the early school days i.e., 7th standard onwards.  I was not accepting  what the teacher says in the class.  Every day,  in the evening, i used to go for revision of the same lesson.  Besides that, I use to rewrite the same lesson, incorporating mine idea.  It is true that, at that age I should not have done or gone by that way. 

Some of the important theories, attempted or rewritten by me in the early school days.

01  Atomic explosion:  For me, it is an important point.  Basic doubt is that, fissile material used in an atom bomb is very small.  Besides that, potential energy stored in the fissile material is very, very small.  How this small amount of energy, when released  is multiplying.  It is true that total energy is not coming from the atomic bomb.  If the total energy is packed within the atomic bomb, how it is stable.

If the explosion or chain reaction slows down, there is no impact of explosion.  Nature absorbs the energy released from the atom bomb and impact is neutralized.  So, to get the best results, it must be exploded within short time.  So, here time is the key player. 

So, slow release of energy is not showing any impact and it all depends on the sudden and abrupt release of energy within short time  plays key role and total energy is not coming from the atomic bomb. 

02  Light:  For me, is also an interest topic.  If we switch on a battery cell light spreads to wide area.  Here total potential energy is not used at a time, still it is being converted into lot of kinetic energy.  Potential energy is being released slowly in an orderly manner and the conversion into light energy continues. 

If we switch on an electric bulb, same results.  Here also energy is released slowly and the conversion continues.

In both the cases, total light energy is not coming from the source.  Small amount of energy released is being converted into light energy only after coming out from the source.   We have only invented technique or method of converting into light energy.  But total energy is not coming from the source.

03  Magnetic Fields:  It is true that charged particles create magnetic fields.  A wire carrying current generates magnetic field around the wire.  It is due to displacement of electrons inside the wire.

To create magnetic field, electrons must be displaced regularly and also in lot of quantity.  If the same thing happens, flow of electricity must be stopped within short area.  But it is not happening so. 

Fewer electrons released are charging and developing an electric field. Similarly, here also, magnetic field is not due to the current flowing in the wire, a few electrons flowing, charges the space and it is being known as magnetic field.

04  Fire:  Fire is a chemical process of combustion, releasing heat, light.  You can cause fire by igniting combustible materials.  I still remember simple incident happened, between me and teacher on a simple experiment.  He lighted a candle and closed it by a glass and when fire put off, he started explaining how things need oxygen to burn. 

Suddenly, I had raised a doubt, why don’t you think that the glass is turning out as an obstruction in between.  That day, it was a big topic.

05  Gravity:  It is another important and endless topic.

Kryptid, due to this type of thinking, I lost control over main subject, lost future and settled as a clerk in Bank.

It true that, life is short and a doubt remained in my mind, whether I could tell these things to the outside world or not. 

Really, I would like to say thanks to “naked scientists forum” Management, for allowing me to share these ideas to the outside world.

Yours

Undoubtedly, it is clear that Gravity is not due to masses

Not clear at all, actually.

At times, surprisingly, you will be asking, something basic, yet it carries meaning. 

“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 Einstein's theory or idea only.  Imagine that space ship is in deep space, far away from all mass concentration.  Yet, as long as the engine fires, person inside the cabin of the space ship, feels as heavy as he on Earth's surface.  In other words there is gravity inside the cabin of the space ship, why?. 

It is a direct question to Newton's inverse square law.  When the space ship is far away, deep space, why, there is no change in gravity. 

That is true.  But, equally, if it is a spatial flow, how there is gravity inside the cabin of the space ship in deep space.  Einstein's Equivalence Principle  equated the effects of  gravitational field to the effects of being in an accelerated frame of reference. 

That is not at all correct.  It is true that cabin of the space ship is closed in a gravitational field and undoubtedly there is Gravity.  As the space ship accelerates forward, no sign of decrease or increase of gravity inside the cabin.  As long as the engine of the space ship is on, it is accelerating forward.  Mean while interaction with the outside space time is impossible.  For that close the cabin of the space ship in a non-gravity field, and if the acceleration, due to thrust of the engine or whatever it may, creates or develops gravity and if the person inside the cabin of the spaceship, feels as heavy as he would on Earth, i am sure that i will accept it. 

Basic doubt of the Einstein is that, space ship is far away from all masses, still there is gravity inside the cabin, how and what produced or warped it. 

It is true that cabin of the space ship is closed in a gravity field.  Even after closing the cabin, there is strong gravity.  This tells us that, in a small area such as cabin, gravity can be quantified.  Besides that it gives same effects as it does on Earth's surface. 

Gravity is not attraction of masses and the same time is not a spatial flow.  It is a field present on the surfaces of the masses, definitely, not all the masses.

One can measure the gravitational force in the same way we have quantified other forces, using a spring arrangement, instead of pulling on the spring, we simply attach an object and let gravity do the pulling. The
elongation of the spring tells us the strength of the gravitational force pulling the object towards the ground.

This gravitational force is called the object’s weight.

Acceleration = Force / (inertial Mass).
For the acceleration to be the same for all objects, the force must depend on the object’s mass, more concretely: the gravitational force, e.g. the one exerted by Earth on each falling objects, needs to be proportional to each object’s mass. Written as a formula,

Gravitational force = Mass • g,

Where g is a factor that does not depends on any of the object’s intrinsic properties. If this formula holds, then, when we calculate the acceleration, the following happens:

Acceleration = Gravitational force / Mass = (Masse • g) / Masse = g

The quantity g is known as the gravitational acceleration, and its value is approximately the same on (and near) the surface of the Earth.

It is true that there is Gravity inside the closed elevator and the person inside the elevator experiences the same weight as he would on the surface of the Earth. 

If the elevator accelerates forward, the person inside the elevator will be pushed back.  In other words, there is additional gravity.  Where this gravity came from. 

If it is an attraction of Earth, there must be change in gravity from closed elevator to open elevator.  If it is a spatial flow, as usual, there must be change, closed elevator to open elevator.  Besides that, scope for change of gravity inside the elevator is also ruled out.

Then, what made or how the Gravity field inside the elevator is changed. 

It helps us to analyse that:
01  Gravity field, giving you weight can be quantified.  There is Gravity inside the closed elevator.
02  When the elevator accelerates forward, the field is changing its position.
03  Additional Gravity is giving additional weight and it tells us that the medium or the quantified Gravity field itself has weight.
04  As the density of the gravity field changes, it itself exerts additional force or pressure on objects, resulting in Gravity.
05  If the medium is weak, there is no gravity and if the density increases, weight increases, in turn creates pressure on objects, which is known as Gravity. 
06  In other words, density of this medium is weak on Moon and is strong on Earth.  By all means, its density is highest on Sun’s surface. 

Further it is also proved that there is gravity, inside the spaceship cabin, which is far away from gravitational masses.  Actually it is a wrong assumption of Einstein that acceleration creates or generates gravity field inside the cabin.  It is true that there is strong Gravity field on Earth’s surface.  When the cabin of the spaceship is packed, knowingly or unknowingly, a part of this Gravity field is also packed and it continues till the spaceship comes to rest or stationary. 

Undoubtedly, it is clear that Gravity is not due to masses or not a spatial flow.  It is a field created on the Earth.

any chances that what we "see" as light speed, or speed of light to be no "speed" at all?
 What if by geometry, photon could be, avoiding time influence, and the traveling thing is the particle photon taking a ride on a geometrical wave of probability?

 Could be that space is at C while light is just taking a ride along with it?

 Or there's anything that undoubtedly, states: Light speed is a speed because...?

It is true that we are taking speed of light as constant.  We also know that Gravity slows down movement of light and bends light.  So, speed of light is different from gravity to non-gravity field.  But it is surprise to me:
01  It is true that there is gravity inside the closed elevator.
02  If the light beam is released from a hole on one side of the elevator certainly it moves out through the other hole.
03  If the elevator accelerates forward, it is the frame that is being lifted, in other words, in turn it lifts the gravity field inside the elevator.
04  Gravity at the bottom becomes dense or stronger. 
05  While coming down, gravity drags light beam.  Light beam also accelerates downward. 
06  When the light source is constant, what makes the light beam to change its position.
07  If the light is independent, nothing can stop it moving straight.
08  If there is a change or bend, while moving in a gravity field, certainly we can say that gravity bends light.
09  But light is changing its path according to gravity.

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...

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.

“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.

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".
