Default Magnetosphere in Sci and Sci Fi

The the magnetosphere of the earth acts as a force field shield
deflecting dangerous rays.
What more does magnetism do that is important to mankind?

It is curves of force.

What is magnetic weight?

Tell us about cosmic rays.

Interstellar space is postulated to have a large quantity of very high-
energy particles known as cosmic rays. The solar wind form our sun
reduces the number of cosmic rays to a much lower level. The earth's
magnetic field creates these Van Allen Belts which shields and traps
the solar wind and other harmful particles. Below the Van Allen
Belts, the radiation is about 10 RADs per year. It is not lethal but
considered health risk. The earth's atmosphere with the ionosphere
further attenuates the radiation level down to such benign level as
seen on the surface of the earth.

How did the Apollo astronauts survive the radiation form solar wind
and cosmic rays without the protected environment of the Van Allen
Belts? They probably will survive with minimal shielding in the
command module for a week and a half, but coming back on earth, they
should be very ill and eventually demise in a few months.

I'm waiting to hear about the cosmic rays that pass through
the earth, coming up to pass through your body from the
feet up, and how "harmless" those are. There's a school
of thought holding that those are to some extent responsible
for genetic mutations.

It tells you which way north is.

It spins the blenders which make all of those mixed drinks that many of
the regulars of these newsgroups undoubtedly consume.

And, most significantly, it sticks notes and the drawings of 6 year-olds
to the front of your refrigerator.

I don't think very many engage in the niceties;
the seem to prefer straight up right out of the
bottle.

That's where I keep my bills, in calendar order. I've
given some thought to drawing the matrix with indelible
marker, but the numbers jump around from month to
month.

You want us to put him in the fridge? F-w's first pun. I hope it did
not hurt too much! Ironically, it addresses the wiitiest mind here,
even possibly, anywhere. Like Groucho, I am suspicious. Get out 'Night
in Casablanca' DVD.

Koobee Wublee is fantastically stupid and is sharing his ignorance on
yet another subject. Do not listen to him.

the earth, coming up to pass through your body from the
feet up, and how "harmless" those are. There's a school
of thought holding that those are to some extent responsible
for genetic mutations.


The only radiation flux that is passing through the Earth is the
neutrino flux from the sun. Given that the canonical description of a
neutrino's interaction with matter is that it can traverse a light
year of lead with a 50% chance of interacting, it is reasonably safe
to say that neutrinos don't do anything significant to us even on
large time scales.

On the other hand, there is a significant cosmic ray flux with
energies than span the MeV to 10^21 eV range. This flux does not pass
through the whole of the planet, but it does pass through the
atmosphere and serves as a large portion of the planetary radiation
background.

This doesn't touch on the solar wind particles that get sucked down
into the atmosphere by the nonlinearities of the magnetic field, but
those are reasonably restricted to the polar regions.

The school of thought that cosmic radiation may be tinkering with our
genetic structure through mutations is not unreasonable.
