As fundamental building blocks of matter and energy, space-time charges can appear as color charges, electric charges, electromagnetic charges, weak charges, and gravity charges called gravitons. The 3rd and the 4th are now combined into electroweak charges called photon, W+, W-, and Z0. All of these different types of space-time charges can be rearranged and grouped together relative to each other. Furthermore, each level of rearrangements constitutes a specified energy of excitations. At present, only three intermediate levels can be experimentally measured: molecular, atomic, and nuclear. The outermost level of attractive gravity rules by the gravitons is extremely weak to allow detection by current technology. The innermost level of antigravity is extremely strong to hinder gluons separation by any advanced accelerator technology.

At the molecular level, the energy of excitation is merely a fraction of an electron volt. At the atomic level, it is a few electron volts. At the nuclear level, the energy of excitation is more than a million electron volts. Keeping these differences in mind, it is plausible that the resonance energy of excitation for detecting a graviton is practically zero while that of gluons is practically infinite.

If it is possible for a glueball to transform into a gluestick then into a gluering then into a gluechain, this is equivalent to the transformation of a tensor into a Hopf ring with properties of Möbius topology of compactification of infinity to zero energy of excitation. Nevertheless, the peculiarity remains why both the theoretical mass of the graviton and the theoretical mass of the gluon is zero. This only makes sense if the theoretical mass is related to experimental detection such that infinite mass and zero mass cannot be practically measured.
