Ah yes, finding the energy background that goes by different names including the Higgs field, the aether, or spacetime. I hold out no hope of proving that there is an energy background to matter, let alone the concept of any amount of energy less that a quantum, i.e. my sub-quanta.

The background of sub-quanta energy would be there even if there was no matter at all. Matter forms from the background energy because when energy density equalizes across all space, there are tiny (quantum sized) spaces that must contain a full quantum of energy simply because the ratio of energy to space is higher than the energy density that causes matter to form, and matter forms in quantum increments.

Those are speculations that are not falsifiable.The physical action of a quantum of energy (a certain amount of sub-quanta energy in a certain tiny space) is to collapse until near infinite energy density occurs and then to burst back into a cloud of sub-quanta energy. But a quantum of energy performing this feat is too small to observe. At a minimum there are 700 billion of them in a proton and ~400 million in an electron; very small indeed.

The collapse is nothing more than the equalization of the energy density within that quantum sized space. As it equalizes it requires less space because the sub-quanta are a group of tinier energy density fluctuations and once the quantum amount of sub-quanta occupy the tiny space required (quantum space), all of the multiple density fluctuations are resolved into one fluctuation which uses less space. The use of less space is the collapse of the quantum.

The resolution of the vast number of tinier fluctuations and the shrinking of the required space to contain the equalizing quantum continues as the quantum collapses until ... until the maximum possible energy density is achieved. The collapsed quantum then bursts back into a cloud of sub-quanta because there is nothing to sustain the pressure.

The evidence is circumstantial. When we see what a proton does, and what an electron does, then we can derive how they work. I described the surface action of a proton and the interface with an election, plus the interface of the electron with the sub-quanta background in my thread about Speculations that Something Preceded Expansion which I linked to earlier.

But those are speculations that are not falsifiable because of the scale of the quanta and sub-quanta.

Clearly from the responses that speculation about such circumstantial evidence receives here at BAUT, there are few members willing to go there.
