When looking through a few books, I ran into one by someone named Jack Armel. It was a theory he developed called "Entropic Space-Time" (also the title of the book). I've never heard (or remember hearing) this theory before...I'm presuming it did not carry out too far (it'd be helpful if someone confirmed this). The theory did not seem too crazy (though I only looked at the Table of Contents and the first chapter of the book); in the first chapter, I did find it interesting how he designated space-time as something with energy -- the structure of space-time was given a charge and was quantized. Does this concept of space-time extend into the heavier ongoing theories of today or is it just left as an arbitrary structure?
