It just keeps growing and growing with pauses between growth cycles It seems that Oblers Paradox would put some constraints on this theory.

Oblers Paradox Is that the correct spelling? Refresh my mind, please, if you would, what is Olber's paradox, in the style of Olber's Paradox for Dummies.
To: RightWhale; RadioAstronomer
what is Olber's paradox, If the Universe is infinte, then why is the sky dark at night?
In an infinite, homogenous, isotropic Universe, the amount of stellar matter increases at exactly the same rate as light intensity decreases, as a function of distance. Thus, every direction you look in, one should eventually encounter the surface of some star. Obscuring matter (dust) makes no difference, as over time the dust would be heated by radiation and radiate the same amount of energy it was "blocking". This means the sky should look like the average surface brightness of a star, but it doesn't.
The classical explanation for Olber's paradox is that the expansion of the Universe accounts for diminished contribution to night sky brightness as distance increases, due to redshift = reduced energy (e=h*nu). Other alternatives include the Universe not being infinite.

Another explanation is the absorbtion of light energy as it travels.
Again, plasma theory offers several reasonable explanations. The big bang theory does not.

Another explanation is the absorbtion of light energy as it travels. If you mean absorption by interstellar dust, gas clouds, etc., it does NOT explain the darkness of the night sky. Any absorbing medium would eventually reach thermal equilibrium, and radiate the same amount of energy it was absorbing, which from an observer's standpoint of sky brightness, is the same as having no absorbing material at all.
There is no incompatibility between the Big Bang Theory and Olber's Paradox.

When are we going to get Hinduism out of science?!?!?!?!? LOL
To: Cleburne
It's true, modern science appears to be an import from Eastern countries, the lands of Hinduism and the lands of Islam. Many will say, oh, no, that cannot be, what about Aristotle and Plato. That is a valid point; Pagan science died with Paganism and had to be reintroduced to the West. Like the rabbits that were introduced to Australia, or the Argentinian ants introduced to the warm coast of France, science had no serious natural enemies in the West, and so multiplied without limit even while dying out in the lands of the East.

Does this replacement of "eastern mysticism" by "Western capitalsim & engineering" (much different than "Grecian philosphy"!) imply perhaps that one works ....
... and the other leads to starvation and early death.

As well as this new kind of earth worship, very much opposed to science and ingineering.
To: Robert A. Cook, PE
I'm going to be lazy and not do the calculations, but if a particle within the sun is undergoing billions to trillions of collisions every second, it seems reasonable to assume that the collision rate would increase during an explosion or implosion during periods between the end of the hydrogen cycle and the beginning of the helium cycle, or the end of the helium cycle and the beginning of the carbon cycle. (That may just be the longest sentence I've ever written.) During the sun's death throes, there would be enormous pressure waves traveling through the sun's core allowing a much larger number of high energy collisions to occur.
So I'm curious why you think repetitive fusion can't occur under these conditions and what your methodology is for your analysis.
