mass is light.

$$ mass is light.

$$ EVERYthing seen or made manifest is mass.
$$ -- Paul (Saul).

$$ hbar
$$ SI mass = --------- = MiNiMUM photon ..in kilograms.
$$ 2*c^2*sec

$$ h
$$ SI mass = ------------ = MiNiMUM photon m1 ..in SI kilograms.
$$ 4*pi*c^2*sec

$$ So, photons doN'T go anywhere ..they simply pass on the frequency.
$$ For example, Planck *discovered* Helmholtz resonator frequency fL.
$$ For example, Planck *believed* that the photons are ALREADY there.
$$ [The LiNEAR wavelength wL is what travels on ..at light velocity].
