Does Ether has a Volume

When a Mass moves arround Ether does Ether produce any Resistance

Is it simmilar to the Water in Ocean Or Air on Earth So that the
Fishes cannot feel the Water and we Cannot see the Air though it is
present every where?

Is Ether also present in Vaccume.

What are the Laws that say Ether Exists.

And Which Laws say Ether do not Exist.

Is there any Experiment to show Ether is present in World.

If Ether is removed from a place will the Light Stop. Just Like Sound
travels from medium. But Sound do not travel in Vaccum. Simmilarly
will the Light Stop when Ether is not Present?

Your rejectioon of the Aether does you little credit.

A perusal of my posts in this newsgroup shows quite clearly that I do
not "reject" the aether. But I do know that any viable aether theory is
experimentally indistinguishable from SR, and that makes them all quite
useless. And I also know that no aether theory has any approach to
quantum phenomena, which makes them excessively naive.


Quote:
Without the Aether we are faced with unanswered questions:
1.- The reaction forces required for inertial and gravitational forces are
considered to be "fictitous" in contradiction to Newton's Third Law.

You ASSUME they are indeed "forces". If that assumption were true, you
would be able to measure them. Please describe how to MEASURE the
"centrifugal or Coriolis force" or the "gravitational force" on an
orbiting satellite. You'll find yourself utterly unable to do so (you
can measure consequences of these "forces", but not the "forces"
themselves).

In GR, none of these are any type of force, and no "reaction force" is
required. For "centrifugal and Coriolis force" this is true in Newtonian
mechanics (they are purely artifacts of using rotating coordinates).


Quote:
2 - Empty space has observable properties in addition to its volume. It has,
for example, a dielectric constant, permeability, a characteristic
electrical impedance (300 ohms) and propagates light at the velocity of C in
accordance with its dielectric constant and permeability.

Hmmm. These are not really "properties" of space itself, but rather in
classical electrodynamics they are relationships among field quantities
that are intrinsic to the fields, not to space. In quantum field theory
they are properties of the vacuum, not of space.


Quote:
It seems absurd to
assert that "empty" space has properties.

Only when you ASSUME they are "properties of space". In modern physics
they are not (they are properties of the vacuum, which is NOT "space").

[To understand this you must learn about quantum field
theory, where it is quite clear that the vacuum state
lives in the Fock space, not in spacetime.]


Quote:
It is not absurd to assert that
"empty space" is actually filled with an "Aether" having those properties.

It's not absurd. But it's not required, either. There is not a single
observation of any sort of aether, and not a single measurement of any
of its properties -- all the relevant phenomena can be explained and
described by classical electrodynamics, in which no aether is present.
And no aether theory has yet even approached describing quantum
phenomena, but QFT (inherently based on SR) does so quite accurately.

Try thinking instead of merely propagating the "party line."

I belong to no "party". You need to try learning some REAL physics. And
you also need to learn how science is really performed.

The aether of the 19th century physicists was assumed to be a
-substance-. In the early days of physics electricity was assumed to be
a substance (some kind of fluid) which could be stored. So the idea of
the Leydan -Jar- was quite literal. Likewise heat was initially belived
to be a substance, the caloric which flowed in and out of material
bodies as they heated and cooled.

Substance based theories were eventually dropped from physics or have
become minimal. Physics is pretty well based on symmetries and fields
right now.

Um.. a bit of circular reasoning perhaps? The fundamental tenet of SR,

the constancy of the speed of light _independant of the velocity of
the emitter_ PROVES the reality of light's carrier medium. Without the
medium, why is not the speed of light additive to the emitter's speed?
Why isn't the speed of light energy-dependant, or even infinite? If
space is 'nothing' and functionally void, what property of the
'Nothing' fixes its permeability/permittivity and dialectric constant
and sets the high, invariant propagation speed of light? Further, in
the absence of a carrier medium, why is there NO PERCEPTIBLE UPPER
LIMIT TO THE AMPLITUDE OF ENERGY TRANSMISSIBLE BY EM RADIATION?

These two Cardinal Points of Evidence (and a half dozen others
mentioned here many times) demonstrate a spatial medium of very high
energy density that not only fixes the speed of light, _but is of even
greater energy density than the most energetic wave it carries_.

Another Cardinal Point of Evidence is the *relativistic effects*
described by SR. Time dilation, mass increase, and foreshortening of
rods, demonstrate a medium becoming increasingly resistive and
"viscous" at high relativistic speeds. If space were 'Nothing', this
onset of "viscous-ness" could not and would not occur and there would
be no speed limit to anything, no mass increase, and no foreshortening
of rods at *any* speed.

SR is a set of **descriptions of effects**. SR does not explain the
_acting mechanism_ CAUSING those effects. Yet the very presence of
those effects are prima facie evidence by which the spatial medium
_demonstrates itself_.

GR is likewise a set of **descriptions of effects**. GR does not
explain the acting mechanism CAUSING those effects. Just for example,
take one of the most dramatic demonstrations of gravity-in-action, a
supernova. What is the literal, active mechanism POWERING the stellar
collapse that powers the fusion that rebounds as the SN blast, leaving
that massive star crushed down to a black hole? Proponents of the 'no
medium', space-as-void doctrine are challenged to "fill in the
blank"____________.
Whatever powers the stellar collapse culminating
in a supernova is a very REAL force, not a pseudo or 'fictitious'
artifact of symmetries/fields, geometry, "curvature" of 'Something
that is yet Nothing'.. or of hordes of "exchange
particles" (gravitons).
Massive gravitational phenomena such as
quasars, supernovae and hypernovae, demonstrate a FLUIDIC spatial
medium under a state of pressurization far exceeding degeneracy
pressure of the atomic nucleus.
The behavior of gravity at all scales
demonstates the pressure-driven, accelerating Flow of that fluid into
mass with mass synonymous with flow sink. And it demonstrates
unification of gravity with the strong nuclear force. Per Occam's
razor, gravity is exactly what it _demonstrates itself_ to
be.

Dynamical 3-Space: A Reviewhttp://www.scieng.flinders.edu.au/cpes/people/cahill_r/Dynamical3Spac...

Abstract: For some 100 years physics has modelled space and time via
the spacetime concept, with space being merely an observer dependent
perspective effect of that spacetime - space itself had no observer
independent existence - it had no ontological status, and it certainly
had no dynamical description. In recent years this has all changed. In
2002 it was discovered that a dynamical 3-space had been detected many
times, including the Michelson-Morley 1887 light-speed anisotropy
experiment. Here we review the dynamics of this 3-space, tracing its
evolution from that of an emergent phenomena in the
information-theoretic Process Physics to the phenomenological
description in terms of a velocity field describing the relative
internal motion of the structured 3-space. The new physics of the
dynamical 3-space is extensively tested against experimental and
astronomical observations, including the necessary generalisation of
the Maxwell, Schrodinger and Dirac equations, leading to a derivation
and explanation of gravity as a refraction effect of quantum matter
waves. The flat and curved spacetime formalisms are derived from the
new physics, so explaining their apparent many successes.

Thanks. In a brief perusual of Cahill's stuff, his term "process
physics" is interesting. Under the CBB model which has been discussed
for years in this NG, all things deemed 'particles' and 'fields' are
in fact *processes* of flow of the spatial medium. All the
fundamental forces including gravity are reducible to one Flow driven
by one Force in the Unified Field of Spatial Flows.
The term 'particle physics' loses its meaning once
the reality of the spatial medium is recognized, and the 'particles'
comprizing all atomic and subatomic structure are recognized as
vorticed Processes of that one Flow.

Often analogies were used, such as the eddies and whorls in a river
which *appear* as discrete, stationary entities but are processes of
the river's flow.. or a candle flame which appears fixed but is a
process of convective flow.
