Scientists may have finally figured out how and why these leaks are appearing in the Earth's magnetic field

Satellite images collected by the Time History of Events and Macroscale Interactions during Substorms (THEMIS) mission revealed another large breach in the magnetic field responsible for protecting the Earth.

The magnetosphere helps protect the Earth from severe space weather, including possible disruptive solar winds, scientists said.  Being able to learn more about these holes will help scientists predict when electrical storms occur.

"The discovery overturns a long-standing belief about how and when most of the solar particles penetrate Earth's magnetic field, and could be used to predict when solar storms will be severe," UCLA NASA THEMIS mission investigator Vassilis Angelopoulos said in a statement.  "Based on these results, we expect more severe storms during the upcoming solar cycle."

Themis research indicates the magnetosphere sometimes has two cracks, which are big enough for solar wind -- with speeds up to 1 million MPH -- to hit the Earth's upper atmosphere.

The solar particles are electrically charged, which was no problem, but our magnetic field has tears that let the particles breach.

"Twenty times more solar particles cross the Earth's leaky magnetic shield when the sun's magnetic field is aligned with that of the Earth compared to when the two magnetic fields are oppositely directed," according to Cal researcher Marit Oieroset.

Scientists figured some type of "closed door" entry mechanism was used, but they weren't sure how important the closed door is for Earth.  Most particles hit the shield and float back into space, but some of the particles that get through are able to get energized while leading to possible power grid outages.

Most solar storms occur during the halfway section and on the final stretch of a solar cycle.  In 2008 it's at a minimum, and will reach its peak four years from now.

Is it so hard to believe that these magnetic holes are man's fault? After all, man discovered this problem, so we must be the cause of it, too. Sure, we don't know exactly how we're doing it, but the most commonly accepted theory is a large distortion generated from millions of refrigerator magnets in circulation. If everyone would stop buying these frivolous magnets to hold everything from important memos to decades old pictures on their appliances, this whole disaster could be mitigated. It's just too hard for many families to let it go, however, as many just like to have the name of their favorite vacation destinations magically bonded to their Maytags and Kelvinators. And since tape just doesn't want to stick to these bumpy surfaces, environmentalist groups are proposing that if people absolutely must have things on their fridges, they should use nails, tacks, or screws to attach these items.

Those who wish to help save the planet by removing their magnets should dispose of them properly. For a small fee, these magnets will be collected and safely stored until they can be properly destroyed. When enough magnets are collected, they will be packed into a rocket and launched into the sun. After millions of magnets are properly destroyed, scientists will then study the earth's magnetic field to see if this measure has worked. If the field doesn't show signs of improvement, then it is obvious that refrigerator magnets are not the only magnets causing the problem, so a new magnet purge of a wider scale will take place. One thing is sure, we must act now, before magnets make the planet uninhabitable.

whoever said the rhyme did the crime.

Oh crap I just said the rhyme.

Funny how that kinda works in real life since most rap "artists" are criminals.

Most rap artists aren't criminals but act like them. Most of these guys were raised in middle class neighborhoods and some have degrees. It's a ploy to sell records, that's all. Do some commit crimes? Sure, it's part of the act. Ask a gang member if he listens to rap. Most don't because the artists are fake. And they're correct.

Is it better to be criminal than to be a phony?
