A Sphere In Time

 A sphere in time and a sphere in space,

$\cfrac{8^3}{6}\pi^2*f^2*m_ac^2=1*\cfrac{1}{Vol_{sphere}}*m_ac^2$

$\cfrac{8^3}{6}\pi^2*f^2*m_ac^2=1*\left[\cfrac{4}{3}\pi T^3\right]^{-1}*m_ac^2$

$f=\cfrac{4*8^3}{18}\pi^3=\cfrac{1024}{9}\pi^3=3527.825\,\,Hz$  Sphere 3D 3527-825 Hz

What is this frequency?  Kinetic photons?
