Louis de Broglie showed us that everything is a wave. Your reference to signals and noise suggests you may be familiar with his work.
The absence of evidence so far in the search for the Higgs field/boson (though CERN might be able to accomplish the feat with it’s new equipment) – puts the emphasis on such theories. After all, a field exists at all points in space/time and therefore the more fundamental structure is space/time itself.
In Wesson’s five dimensional relativity, two times – the particles observed in our four dimensional space/time could be multiply imaged from as little as a single particle in a fifth time-like dimension. Others theorized that it is possible the particles we observe are all actually massless, their apparent masses corresponding to extra-dimensional momentum components we can’t as yet detect.
Of particular interest to me are theories which involve more than one dimension of time.
Moreover, advances in information theory and molecular biology evidence the difference between what is life v non-life/death in nature. Information is the reduction of uncertainty (Shannon entropy) in the receiver (or molecular machine) in going from a before state to an after state. It is the action not the message (e.g. DNA or RNA.) The message survives, when there is no successful communication, there is death or non-life.
We have discussed these points many times on the forum, e.g. here. And they are more thoroughly explored in betty boop and my book Don’t let science get you down, Timothy..
