The Theory of Invariance

Sloat, Your mass(10E54kg) looks good to me. Why do you need a speed of gravity? It seems to me gravity is a force which is a field and not something in motion.

[Stoat] "Tool steel s a very rigid material but I'm saying that the aether is about a hundred billion times more rigid, ..."

The particle movement associated with transverse waves depends on the medium.
- In a solid, the particles move up an down
- In a liquid (e.g. water waves) the particles contributing to the wave describe circles

In a solid the upwards movement of atoms creates a stress in the material that forces the atoms to reverse their direction.
If aether would resemble a solid, than indeed it would need to be very rigid to accomodate for the high frequencies that can be propagated.

I a liquid the upwards movement of molecules causes other molecules to follow the opposite direction at the same moment in time.

Obviously aether does not behave like a solid (and not exactly like a liquid either).

Every medium has it own way to propagate waves, so to aether can have its own 'unique' way to propagate waves.

Bart, are you perhaps proposing 'new physics'? It would be cool if you are, and this is certainly the right place to do so. But truely new physics is rare these days, and we are skeptical. You should be prepared to offer some theoretical details and some experimemtal or observational evidence to back up your claims.

Meanwhile, in the world of current physics, there are three ways for wave energy to propagate
<ul><li>longitudinal waves</li>
<li>transverse waves</li>
<li>surface waves</li></ul>
Water waves are not an example of transverse waves. They are an example of surface waves. Surface waves are a combination of longitudinal and transverse waves (hince the circular particle motion, rather than just side-to-side or just forward-to-backward) and can only exist at the boundaries of a medium (which means that surface waves are a 2D phenomenon ...), where special conditions can supply an alternate type of restoring force to replace the usual one that is missing in the bulk of the medium (... and that longitudinal and transvesrse waves are 3D phenomena).

Transverse waves can not travel within a liquid or a gas, because there is no restoring force to bring the particles back to their starting point after being disturbed. The restoring force for transverse (side-to-side, relative to the direction of wave travel) particle motion within liquids and gasses is missing because Young's modulus is zero for these media types.

<br />Hi Stoat,

In Dan - Lynn experiment, I claim that Lynn also see both light bulbs flash simultaneously. Then from this view point, I say that time is absolute, then space is also absolute. There is no time dilation or length contraction in theory of Invariance.

About the speed of gravity....

In Invariance, the speed of gravity is immediately. Velocity of light in vacuum is an property of light. c is not a final limit.

is that immediate in all times or just forward time ?
"so a gravitational comunication system could comunicate
with someone on the other side of the universe instantly
with no delay in time; just like dna splitting stress tests"

Hi evolivid,

Thanks for your reply,

In Invariance, speed of gravity is instantaneous in all time.

Hi Bart, I did say that I think the Aether is a viscoelastic. A non Newtonian substance. Think of custard, you could fill a swimming pool with it and run across it. In fact if the pool were big enough, you would find that you had to run at a certain resonant speed, and you would have great difficulty in stopping. Then of course you would sink. non newtonian substances act rather strangely. Fill a centrifuge with egg white and drop spheres into it is the classic method for study of this. Well, you can make viscoelastics which are extremely rigid, a topical case is the use of these materials for earthquake dampers in buildings. Buildings expand on one side in the morning, and the other side in the afternoon. The dampers compensate for this slow expansion. Hit the building with a sudden wind gust and the dampers stiffen up, they then slowly release that energy. (Incidentally I did try to get a few experts to look at the damper question vis a vis the twin towers. No joy at all in that the maths necessarily involves complex numbers and not many architects want to do the work)

Negative refractive index viscoelastics are stranger yet! But let's think about a simper aether for the moment. A planet and a sun both have their own aether atmospheres. So two "bubbles" in equilibrium, otherwise the larger bubble would consume the smaller. Now I go with Robert Carroll's fourth power fall off but I don't think any great problems will result if we assume a square law fall off for the moment. We've also go with this set up a Le Sage shadow cone. Agraviton will barely "see" the sun and planet, it may see the cores and the Schwartzchild radii but those radii are e.m. radii. The gravitational Schwartzchild is much smaller, about 1E-30 metres for the Sun. A very thin tapered wave guide perhaps? Now a tricky bit, consider a shadow to be a negative wire. if we allow ourselves neg r.i. then it is a wire in gravitational space but a shadow in e.m. space. The cores will be spherical lenses in e.m space but mirrors in neg r.i. space. Note also that longitudinal waves are supposed to take a lorentzian contraction but transverse wave not. I don't think that's quite correct, phonons can travel faster than "sound" in a medium of a certain r.i. rather like Cerenkov radiation.
