Why the perfect background of the ISU isn’t luminiferous aether either.

This thread adds content about the red shift, in particular the gravitational component of the red shift, and the related topic of why the energy density of space does not act as a medium for the propagation of light waves. The new ISU content introduced on the recent Infinite Spongy Universe thread, “The Infinite Reach of Gravity in the ISU”, has been added to the conveniently recapped and sequenced list of events that characterize the ISU in post #2 on this thread. Please note that the recap in post #2 includes the quantification of the EEP presented on the linked thread.

Here is a Glossary of terms used to discuss the ISU from an previous thread.

The content about the gravitational component of the red shift and why the energy density of space does not act as a medium for the propagation of light waves is covered in the third post on this new thread.

If you are already familiar with the ISU from “The Infinite Reach of Gravity in the ISU” thread you can skip this recap, and go the new content in post #3.

For those not familiar with it, the ISU is about empty space that has always existed and has never been empty. That sounds like a paradox but it simply means that space itself can be empty, but it is not. It contains energy referred to as the energy density of space.
It is inescapable that reasoned and responsible speculation about pre-conditions to the big bang takes place. I am conducting such a process when I talk about the ISU. To some, a little speculation is just as bad as speculation about little green men. The ISU presentation is reasoned and responsible speculation about what the universe could be like if it was composed solely of infinitesimal indestructible elementary energy particles that have always existed.

There is a proposed testable aspect of the EEP discussed near the end of a previous ISU thread. Such a test, if devised and successful would bring the ISU into the realm of science. Acceptance still awaits a repeatable test proving the existence of the unifying particle and a peer reviewed paper about how that particle accounts for the energy density fluctuations that characterize the Infinite Spongy Universe.

That post lead to a thread about “Isolating Protons” which ended with this post: http://www.bautforum.com/showpost.php?p=953526&postcount=10

A test may very well be devised, just probably not in my lifetime. The expected discovery of the unifying particles that make up the sole content the ISU could be detected by such a test.

Post #2 lists the events from the referenced ISU thread conveniently recapped and sequenced for you right up to the point where the new content is to be added.
