Most new theories give rise to as many questions as answers, and here are other questions that ES raises:
1 - How would ES affect the flow of time?
2 - How might violent stellar events affect and be affected by ES?
3 - Does ES infer that stars are not at the presently observed distance, but are actually at the observed distance slightly modified (probably somewhat diminished) by the Hubble constant?
I know that I am not a physicist by any means. Nor am I in any way qualified to presume to knock the life's work of Edwin Hubble and that of thousands of other physicists and astronomers, famous and not-so-famous. It is better to assume that I am wildly inaccurate in my observations and conclusions, and to remind myself the danger inherent in a little knowledge. But who knows? Maybe I hit on something, the layman's physics equivalent of winning the lottery. I expect to receive scorn, derision, and perhaps a little pity from those who do know far more about physics than I will ever learn...but maybe I'm right! Time will tell.
