No, there isn't, so you're not off to a good start here, assuming you're asking the question because you believe there is controversy.

Mass and energy are equivalent, or hadn't you heard? You can get dicy with this and start in on QED (quantum electrodynamics, but you'll have to take the lead in saying there's no "there" there. The rest of your waffle seems to be about "things" which have to be "there", in some sense. This is an ancient waffle, but people carry it on because they can't keep up.

There's that ancient waffle, again. See above, about your myopic focus on "things" that have to be "there" in some sense in order for you to treat them as physical, rather than mental. Sure, you can argue that waves are conceptual, but so what? Waves are not analyzed without assuming physical processes in physical media. If the ancient waffle was good enough for the Greeks, then it's apparently good enough for you.

At last, you're trying to make some sort of point about the way thinking is "immaterial", but see above, for the ancient waffle about waves and such. Try again, because it's not clear what your point is.
