Title: Gravity and Inertia are two sides of same phenomena
Post by: kpvats on 23/04/2018 02:15:23
Gravitational mass and inertial mass, have been found quantitatively same in experiments, but they are still considered two different concepts/phenomena in all physics literature. This article puts forth the idea that they are physically one and same. Therefore they are also always found to be quantitatively same. Which is not a coincidence; It is proposed that gravity and inertia are indeed one and same phenomena. This concept of gravity and inertia being fundamentally identical phenomenon is presented to readers for proving or disproving if someone wants to. For clarifying purpose, same concept is stated multiple times with slightly different wordings.

Terms used -
1. Curved space, space curvature, rootedness, space dip etc. All such terms refer to the space time curve as postulated in general theory of relativity.
2. Mass, energy, mass/energy etc. All such terms refer to generalized notion of energy as postulated in general theory of relativity.

Gravity -
We know from general relativity that gravity (generally speaking) is curvature of space caused by mass/energy. This curvature of space manifests as gravity for bodies other than the one that causes the curvature. I will take this description of gravity as it is.

Inertia -
Inertia of a body/mass is defined as tendency of the body/mass to resist a change in its state of rest, or uniform motion.
What inertia actually is  As we know, all mass/energy curves space in their vicinity. I propose that this curved space is a dip or rootedness of the mass in space with a certain state (of rest, or uniform motion). A force is required to change the state of this dip/curve/rootedness. Thus inertia of a body is a consequence of curving of space by mass of that same body. When we push on a mass, we are pushing on this dip of space.
A mass/energy curves space, this curved space manifests as gravity for other masses/bodies. Same curvature, as a whole, manifests as inertia against change of state of that mass.

Not just Equivalent, they are one and the same 
Origin of inertia and gravity is same which is curving of space due to mass/energy. The difference lies only in what we call gravity and what we call inertia.

 We have chosen to call the effect of a curved space on other bodies as gravity.
 We have chosen to call rootedness of a curved space resisting change of its own state as inertia. There are no two masses, it is just one mass, one phenomena.

They are same phenomena because they both are caused by space curved by mass. Only that we have chosen to call the mutual effect of the curvature as gravity, and call the isolated effect as inertia. Inertia is a bodys own gravity that resists any change in its uniform state.

It is important to note that in some contexts we already consider effects of a bodys gravity on itself, like a body gets round shape due to its own gravity, a nuclear reaction starts in a star due to its own gravity and so on. These examples should not refute the isolated nature of gravity that manifests as inertia. On the contrary, these examples support this proposal because; when we can attribute a planets round shape to its own isolated gravity, can attribute a stars nuclear reaction to its own isolated gravity, why a bodys inertia can not be attributed to its own isolated gravity? Actually, round shape and nuclear reaction like phenomena require a certain minimum amount of mass. On the other hand, detecting inertia has no such minimum mass requirement, just like detecting influence of a known gravitational field on a mass has no minimum mass requirement. Gravity and Inertia are fundamentally same phenomena.

Inertia is a measure of a bodys own gravity acting on itself against change of its uniform state.
Gravity as we know, is a measure of one bodys gravity acting on another.
They are two sides of the same coin.

Gravity is a measure of coupling strength of a body to a known gravitational field.
Inertia is a measure of coupling strength of the body to its own gravitational field.

When we try to change state of a body, we are doing so against the coupling strength of the body to its own gravitational field which in turn, is coupled to the uniform state of the body. The body can not escape from its own gravitational field because the field moves with the body. This may be one of the reasons that we do not recognize inertia as bodys own gravity.

Inertia and gravity being proposed as one and same phenomena, there is no need of proportionality between gravitational mass and inertial mass. They are one and same thing. There is no need of proportionality and setting the proportionality constant = 1.

Ok, that's a lot to read.

Gravity and inertia?

These are words trying to catch up to the idea of actual physical processes. "Gravity" is a force that we've tried to relate with mass, and how that works. Inertia likewise a descriptor putting tabs on the idea of changing the effect of mass. Gravity being the "naturally" calculated force between mass, and inertia being the what some would consider other side of the coin.

In the absence of science, would there be a thing such as inertia?

This is the thing, "you change the natural conditions of an environment, such as entertaining the idea of "inertia", how far are you going to get in understanding reality as it naturally stands?"

You say When we try to change state of a body, we are doing so against the coupling strength of the body to its own gravitational field which in turn, is coupled to the uniform state of the body. The body can not escape from its own gravitational field because the field moves with the body. This may be one of the reasons that we do not recognize inertia as bodys own gravity. 

You might like to look at the motion of charged particles in constant motion vs acceleration, there are some parallels to what you are saying here.

Yes. Gravitational mass & inertial mass are the same thing. This is due to the way they are measured. Both are inertial.
At a micro level (eg photons, eg electrons, eg quarks) they are not the same thing -- here gravitational mass & force, & inertial mass & force, have different micro-causes & different micro-effects.
At a macro level this difference is nearnuff zero.

However i dont believe in space-time -- & i dont understand Einsteinian inertia within SR & GR & space-time.

It is proposed that gravity and inertia are indeed one and same phenomena.

Inertial mass is the mass that appears in Newton's Second Law

F=ma

Gravitational mass is what appears in Newton's Law of Gravity

F=GMm/r^2

The m term masses cancel out. One force is produced by Gravity the other is due to acceleration, which are not the same thing, whilst are viewed as having equivalent effects.

You could always confuse the discussion by introducing relativistic effects https://en.wikipedia.org/wiki/Mass_in_special_relativity assuming of course you believe in time dilation and space time
