I just thought of this idea, and I don't know if it is original. It answers the old controversy about action at a distance, because forces can traverse pressurized vessels, and the universe must be under pressure if its envelope, whatever that is, is being forced to expand. (Big Bang or however)

It eliminates the need for a luminiferous aether.

Also, Mass may be the contained-energy pressure of a 'particle' reacting against the pressure in the 'vessel' of space.

I only thought of it this morning but. there may be other significant associations.

Interesting, but you should bear in mind:

1) The expansion of the universe has nothing to do with an "envelope" or other barrier or edge to the universe.
2) Even in a pressurized container, forces traverse the container because of impacts.
3) The best theories that describe the expansion of the universe have a very sophisticated use of "pressure" associated with the contents of the universe.

That concept was noted in a prior communication, in that other Galaxies, can indeed form a limiting external "pressure" or restriction. I assume you might concur that there is therefore, no restriction to the "expansion of the Universe" and that is indeed a perpetual cyclic variable universe. wbw

Bearing in mind that the universe does not (?) have an envelope, the fact that the galaxies are moving away at light speed indicates a force of expansion, and a force, such as voltage has pressure, and, Yes, the resistance is the other galaxies in its way. It's not a bottleneck, but it is an obstructing element. So, perhaps the pressure is tiny.

Light, which is a force radiated across space, travels at less than its massless (instantaneous) speed might suggest, because the particles of pressurized space are moving as light passes over them. Here it must be noted that being on one of these galaxies we don't recognize the expansion speed. However,expansion of the "rubber surface of a balloon" indicates that whichever direction light travels the particles would be moving with it. Thus, c, the speed of light is less than instantaneous.

Mass would increase at high speed because the reaction to the pressure would be greater. Thus, light would be limited by the expansion speed of the universe and matter by the increase in mass. So that c would be the highest speed for the universe.

Thus, light speed c, in this situation, is the difference between massless light (instantaneous) and the expansion rate of the universe, which also equals c. In this case, c^2 means light speed discounting expansion rate, and mc^2 is the energy available in the mass of an object traveling at light speed through the expanding universe.

There appear to be points of agreement with present theoretical speculation, and other possible explanations of present assumptions, when the universe is considered to be pressurized.

Right or wrong, new ideas that appear consistent with present knowledge should be taken seriously, as there is something wrong with a theory in which non-directional space changes direction around massive objects.

Gravity, in a pressurized universe, might be nothing more than the inertial resistance of expansion forces, around massive objects. (As expansion occurs as on the surface of an expanding balloon, the change in pressure around a massive object would appear to emanate from the object.)

This is interesting. The speed of expanding space is proportonal to distance. Dpes anyone know how to tell the rate of expanding space between two known points?

Yep. The expansion between two points leads to a time delay. If we assume that one location is stationary, then the light from the other location will be shifted towards the red end of the spectrum due to the effect of the time delay. Measuring the redshift will thus give a measurement of the recession.

I was hoping for a more concrete formula that doesn't depend in light. The rate of expansion is proportional to the distance between the objects, the farhaer away the faster space is expanding between them.

How fast is space expanding between the earth and the sun or moon? Gravity keeps the earth orbiting in a consistent orbit around the sun even though space is expanding around it.

Shouldn't there be a wake of some kind. Does anyone have a good reference for more info on how this works?

but...... space isn't pressurized

I find the semblence between my home planet and Earth fascenating.

I know space isn't pressurized. I'm just interested in this topic. I'll post my question in the QA forum.
