I think that the science go fastly with 5 Milliards of breins thinking the speed of the MHz : mégaherz 10 in the power 6 oscillation per second 3MHZ to 12,9 Km/sec.

THe seismic holography in the spots of the sun varies with the line of view (sight) of angle thrown (planned) on the plan containing the magnetic field and the vertical direction.
So THE SEISMIC holography varie with the see-line of the magnetic field, i imagine some symbols.

v>W : the seismic holography.
=+/- : varie
(°) i : the see line
: the magnetic field
: the magnetic field of the earth

I do a mistake in the title >< for
The science must be more easy to evolue fastly....See you
