But unfortunately, because the energy level required to discover such particles is too high, far beyond the upper limit of current collider energy intensity, they remain unobservable.
As for other theories like particles with extra-dimensional properties and parallel universes, they are even more abstruse and beyond reach.
So even though string theory, or the M-theory proposed by Edward Witten, has demonstrated high mathematical consistency and profound structures, it is regrettably untestable in the field of physics.
However, Qiao Ze's intuition told him—perhaps the graviton derived from superspiral algebra was real and already proved that the Grand Unified Theory does exist. Moreover, even with current technological levels, it could at least be partially validated.
