Good article about the breach being known in advance.

That article has nothing to do with the breach. It is about predicting sunspot activity.

What Im gathering from what I have read so far is that the sun cycles create solar flares which create EMP pulses.
IN theory if a big enough solar cycle hits our planet. It could send a world wide EMP pulse.. Knocking out all of our current machines, and tech?
Computers, Cars, anything with a microchip that can not take the energy produced from such storms?

So far thats what I gather.. But Im sure with more reading Im going to find other ill effects this will have on our planet.
A world wide EMP is pretty bad news as it stands..

It is not an EMP (electromagnetic pulse). Similar effects though.

Solar flares produce an increase in the flow particles from the sun (the solar wind). When there is a large increase it can result in a geomagnetic storm which can last for a couple of days. Some electronics don't like it but there is a larger risk to our electric power grids. Transformers and generators can be severely damaged. Long pipelines are also at risk.

The Earth's magnetic field deflects much of the Sun's proton flux from reaching the level of the atmosphere where what is not deflected causes ionization of the atmosphere and gives us the auroras in the North and South.

The Earth's magnetic field does not and can not deflect Cosmic rays which are neutral particles like neutrons which are not possible to deflect with a magnetic field because they have a neutral charge.

The cosmic rays are very fast neutrons which are mostly remnants of stellar explosions in the universe. They are absorbed by collision with atmospheric gas atoms so any hypothesis about cosmic rays becoming more of a problem because of these holes in the Earth's magnetic field have no basis.

This breach could allow much more solar plasma into the Earth's atmosphere though which during a heavy solar storm could be a problem and increase the violence of storms.

No magnetosphere no atmosphere, so yes it does protect us. it will deflect the solar wind depending on the polarity of the interplanetary magnetic field. otherwise it redirects the particles along the field earths lines at the poles to cause aurora.
I'm a little confused at what your saying here. Or are you talking about uv radiation?

Yeah, the solar wind isn't composed of high energy particles of the likes of cosmic rays, however there are solar cosmic rays (stupid name) from flares. depends on your definition of high energy I guess, solar cosmic rays can be up to 10 billion eV. I'd call that high energy.


The magnetosphere is not the only protection from the solar wind. Venus has no planetary magnetosphere and has a dense atmosphere. In lieu of a planetary magnetic field, an induced magnetic field forms, produced by interactions between the solar wind and the ionosphere. It would take a very long time with no planetary magnetosphere for our atmosphere to be stripped away if it happened at all.

I'm talking about both UV radiation and high energy particles (both cosmic rays and the high energy particles from the sun). The magnetosphere does intercept some of these but even if it didn't, the atmosphere still would. The atmosphere can deal with high energy particles better than the magnetosphere can. Of course, in case of a gamma ray burst or some other truly awesome event, neither our magnetosphere nor our atmosphere would help. But for the ordinary, everyday stuff, the atmosphere works fine.

>> What about the interaction of the Magnetic field to create lighting? As I understand it, they now believe that we have "space lightning" or more accurately, discharges between clouds and space. The other end -- what we see, is the discharge of the cloud to the earth. It isn't friction causing this.

We get our ozone from lightning -- and THIS is what helps the atmosphere shield us.

At a guess from what I've read, without the Magnetosphere, the ionosphere might be depleted in about 10 or more years.

Venus may have a heavy atmosphere -- but it is very different, and I don't know if it stops a lot of the UV rays with anything more than lots of sulfuric soot.
