As we have strayed into fields and particles, I think this would be a good point at which to check some of my thoughts/questions on that subject.
1. So far, what I think I have is that fields permeate the cosmos. (Is this theory, or is there any way in which it has been/could be established?)
2. On average, fields may be measured as zero or non-zero, at any point in space. (Is that their energy?)
3. We detect fields by observing disturbances in them.
4. I assume this also applies to the gravitational field, because, although gravity waves have not yet been observed directly, we can detect it only because it is disturbed by the presence of matter and/or energy.
5. The normal form taken by disturbances is that of waves.
6. In quantum field theory the waves are [also] particles. (Are there any fields that cannot be described as quantum fields?)
7. All particles are associated with fields, but only at quantum level is this of significance in the present state of our knowledge.
