IMHO, you are using the word "matter" too loosely here!
In terms of what the the physicists are doing, I don't agree with you. The reason why they are called "physicists" in the first place is because they are studying physical stuff only!
One has to be able to transcend the physical matter in though in order to grasp what it really is. Maybe that is more like meta-physics, or something like that...
I can also grasp your lingo, but I don't necessarily agree with your statement that "they have defined subtle matter, and matter that can even be in more than one place at time". In general, traditional science tends to say that anything that is discovered that is considered to be a building block of matter is generically called a "particle"! Then they also say that, those "particles" tend to have both wave and mass properties, but not both at the same time! That is bogus to say the least!!!
To me, those are very confused messages and statements since they continue to ignore the basic principles of wave constructs at different frequencies..
