The 4x4 is organic material and not subject to rigorous analysis before you hit it so it is unlikely that you will find a nice formula.
There are many sources which you can consult about the average strength of a 4x4 post.
1. It is a change of geometry not just coordinates.
2. Minkowski space has nothing to do with conformal mapping.
3. I have no idea what you are talking about when you mention torsion.
For a wavelength of EM radiation to be absorbed it must correspond to an energy level in an atom. Consider the http://en.wikipedia.org/wiki/Hydrogen_atom#Energy_levels".
At longer wavelengths, there is no corresponding energy level for the EM radiation, thus the wave passes through the body...
I don't think the neutrino communication is viable or really speaks to the OP.Rephrasing the original question: What about EM radiation makes it the only viable candidate for sending signals significant distances? Is that that EM is a dipole force? Is it because of its range (obviously)? Is...
I am not seeing that thread.
This type of communication at best seems like binary unless you are using some sort of pulse-width modulation (distance between pulses and width of pulses encode the data). There are obviously some very significant engineering obstacles to creating, modulating...

My question about mediating particles and forces related in a round-about-way to the question original question: Is there any other way to send a signal other than EM?
If there was such a force other then EM (or gravity) that could be used to send signals, wouldn't we be able to...
Consider that the forces have mediating particles (gravity is undetected).
Is having a mediating particle a requirement for being able to send a signal?
Is there any other way to send signals a significant distance other than with EM radiation or (doubtfully) gravity?
By signal I mean the complex information that we are able to send via radio or other EM transmission.
I don't think there is any other way other than EM radiation but I cannot...
