Physics questions that keep me up at night

After reading Brian Greene’s “The Elegant Universe” I was left with many questions unanswered.  I submit these ideas as proof of my lack of understanding the mathematics of the standard model and quantum physics.  However, my intuitive knowledge of wave propagation as an audio engineer drives these hypotheses and questions.  I welcome all criticism and corrections:

The Density of Empty Space

Electromagnetic power diminishes over distance which seems to indicate an inherent “grain” to the fabric of spacetime.  Does this correspond to the Planke length and speed of light?  This dissipation of electromagnetic waves over a distance should reveal the inherent “friction” or impedance of spacetime; just as sound waves diminish due to the friction and conversion to heat of air molecules.  Can the “density” of space be correlated to the speed at which vibrations pass though it?  How tight must the bonds between “grains” of space be to correlate to the speed of light in a vacuum?  Do the properties of electromagnetic radiation indicate a solid, liquid gas, plasma or some other phase?  Obviously it is not a phase of matter but the correlation between vibration in materials of any type can’t be ignored when looking at space.  The universe is elegant like that 🙂

Does the density of space, when referenced as a resonant body, tell us anything about gravity?

Since matter exists as points of resonant energy within the medium of space, it makes sense that we see the speed of light as a constant.  Perhaps it even indicates a Nyquist frequency with regards to the “resolution” or “pixel size” of matter?  It stands to reason that space may have dynamic varying density due to many factors.  Perhaps the resonance of particles not only displace space (causing gravity) but also “heat” it and change its density.  It seems the speed of light will remain constant from the perspective of anything made of matter since it’s nature (resonant frequency especially) is bound to that speed constant.  Even if the density of space and it’s relative speed of wave propagation changes, anything that relies on this speed should not be able to detect the change directly.  Only by observing the behavior of other resonant particles from a distance should the variation in density be detectable.  Is it possible that this variation in density can account for “dark matter/energy” since it’s only real evidence is an excess of gravity?
