[snip] I doubt this is actually a big deal. I think that even with no magnetic shielding at all, the Earth's atmosphere would be more than adequate to the task.
Besides, how do we know the magnetic field affords any shielding at all? As I see it, for every particle that is deflected, it could equally well be aiming another particle directly at us that would otherwise have missed. Regards, Robin van Spaandonk <[EMAIL PROTECTED]>
