Fluctuations in pressure at time scales of the inverse collision frequency will be dampened/averaged out by the inertia of the balance such that a stable reading of the mass, the gravitational mass of the closed system, is obtained. Although nothing at all is at rest inside the box, the gravitational mass is equal to the rest mass of the box as a whole! The rest mass of the box is not equal to the sum of the rest masses of its contents. The reason that we find Mg = M0 is that we have a closed system with the centre of mass of all the particles at rest...
...the photons, are gravitationally red or blue shifted at upward or downward propagation respectively. This again results in a net (radiation) pressure on the balance [2]. The shorter the wavelength, λ = 2π¯hc/E, of the photons, the heavier the box.
The “photon” can only be weighed if it is contained in one way or another, so that its centre of mass is fixed (on average)....It shows that the term “rest mass” really only means that the centre of mass of the object is at rest in the frame of the observer.... every time we think, at first glance, that we are dealing with a rigid chunk of matter (planet, brick, atom), it appears to carry a lot of dynamics at various length scales and energies. The smaller the length scales, the stronger the forces involved and the higher the (binding) energies, and hence the corresponding masses, relative to the rest masses of the constituents. We could wonder whether this finds it climax at a point
where an elementary material particle is build of constituents that have zero rest mass,
with only kinetic and potential energy to make up for its mass. That this should be the
case for the electron, but at the same time seems quite impossible [3], is well known [4].
What is intriguing is that matter’s most basic building blocks, the elementary particles, all have non-zero spin, intrinsic angular momentum, which seems to imply that they all must
have some sort of intrinsic dynamics. Hypothetical structures which do not have internal
dynamics, such as point particles and hard spheres, do not exist. So what is matter really
made of then? In the Dirac theory, the electron is like electromagnetic energy quivering at
light speed, just like a photon in a box [5]. If really so, matter is light

the kinetic energy disappears and stores it in the quantum
Right that had to do with the frequency because mass and frequency... by Planck and Einstein, mass is related to frequency... it had to do with the mass....and that very very precisely doesn't change as you go around in loops... Thank you again for your comment about Hermann Weyl...that was to do with the mass. But that's certainly very relevant. Very relevant in CCC [Conformal Cyclic Cosmology] because the mass has to go away as you cross over. That's the whole point. Is that you get a phase, a relation between the frequency. So it's a quantum ... It's Einstein and Planck together, tells you that mass and frequency are basically equivalent. ...So if that changes if you go around a loop, you're in trouble, you're absolutely right....
