When I imagine the fabric of reality, like a fundamental particle, a wave function, or a field, I can only imagine something that is either palpable or see-able. However, our model of reality is the only thing that allows things being palpable or see-able. The subjective experience of knowing those objects – that is, seeing or feeling them – is not inherent in the fabric of reality.
So what IS it? What IS a field? Is it a concept, a pure idea, a mathematical object? What is the distinction between a pure idea, in Plato’s sense, and the fundamental tissue of reality? (EDIT, one year later: since there are concrete things, something must ‘breathe fire’ into the equation, into the Form, into a mathematical object, as Hawking has said.)
