stars and galaxies as variable lenses

If we imagine stars as being surrounded by gas that is gravitationally attracted, in a “ball” of gas that surrounds the star. This gas “encapsulates” the star and the light emitted must “pass” through the gas “surrounding the star, and has an effect on the light we observe.
If the star ejects material “gases” are speed up and “projected” outwards and as an optical effect the light from the star is being focused as a “shock wave” of gas is rolling outwards from the star center.
As this shockwave travels outwards its effect is a moving magnifying glass that changes focal depth through the medium of the gas. This has the effect of changing the colour of the light that is emitted.
When the shock wave has reached the outer edge of the gas “bubble”, it recedes back to the center and the optical colour of the light from the star is again changed as the size and diameter of the gas “bubble” shrinks.
In this way the optical colour observed can be influenced by the movement of the gas “surrounding” a star. So if these shock waves can alter optical colour, can they also effect red shift?
When we imagine the galaxy as a double convex lense, and we have a gass medium in our galaxy, we should also be looking for the expansion and contraction of our galaxy lense as a source for optical colour change and another source of red shift.
If the galaxy “lense bubble” is expanding then the optical colour and red shifts should increase, when we observe objects outside the galaxy bubble.
If the galaxy lense is shrinking the effect is the optical colour and the shift change is in the other direction.
When we look at the shape of a lense we are also looking at a moving magnifying glass as the gas medium expands and contracts.
Its very unlikely that any stars don’t from time to time effect changes in the shape and size of their lenses.
It also likely that as super massive blackholes consume varying amounts of matter, that the bubble surrounding them expand and contract acourding to volume of matter injested.

That is cool as heck. Sure shows light bends in a gravitic field ala Einstein.

An interesting theory XPLODER,
one as yet i have yet to digest properly as my time on here is nearly at an end,
i will come back to this tommorrow,

here is a crude diagram of the change of area of the galaxy "bubble" and its effect on observable location of objects out side our galaxy



as the lense expands and contracts objects are optically lensed into different apparent locations
so if the lense is expanding does this effect the "perceived" red shift?
