Solar storms spell trouble for GPS

Or it just does like the AC current in the power grid and
switch to the other side of the power curve. The actual
material doesn't have to move, the energy to flip over
billions of tons of spinning matter isn't there. But as an
A/C generator, it is just a question of electrons.

| What this program stated and I had read it elsewhere, is
the magnetic
| core within the earth had flipped every 200K to 700K
years. Geologist

the last one
| was over 700K years ago. The north magnetic pole (as we
know it) flips
| to the south pole.
