Mystery of Earth's radiation belts solved
Nature News ^ | 25 July 2013 | Ron Cowen

Van Allen belts accelerate their own particles rather than just trapping them.

The two concentric rings of high-speed particles that encircle the Earth are finally giving up the secrets of their origin — 55 years after their discovery. Two NASA probes have found evidence that the Van Allen belts, as the rings are known, are responsible for accelerating the particles, rather than collecting energetic particles that originated elsewhere. Space scientists think that their latest findings1 could also account for the even more energetic belts circling Saturn and Jupiter, as well as high-energy radiation associated with worlds beyond the Solar System and even some Sun-like stars.

For several years after 1958 — when space scientist James Van Allen and his colleagues identified the radiation belts that now bear his name, using instruments aboard the first US space mission — researchers theorized that the rings’ electrons came from distant reaches of Earth’s magnetosphere, the bubble of space dominated by the planet’s magnetic field. They proposed that as the particles drifted closer to Earth and encountered stronger magnetic fields, they would accelerate and settle into a ring-like configuration.

But this type of acceleration process would take days to weeks and best describes radiation belts that vary only gradually over time. In the 1990s, satellites began to reveal that the energy and density of the Van Allen belts changed more quickly. As a result, a competing theory for the origin of the belts' electrons began to take hold: that charged particles do not come from afar, but are produced locally, when electric fields within the belts rip electrons off from wandering atoms and accelerate those electrons to nearly the speed of light. This process could alter the density and energy of the belts on scales of seconds to hours, a theory that matched better...

Torsion field Physics, no doubt about it.

You are a scientific kindergartener. Apparently you have never studied any physics what so ever. Please quit trying to make everything about your prejudices.

The earth itself is in a warp bubble and we can just take the planet anywhere we want in the universe if we can figure out the owners manual.


Unfortunately, the clock is still flashing “12:00.”

Once global warming dies out, the looney left can start fretting about the destruction of the Van Allen belts by fracking.

The only things I remember about that movie was that it was bad, and Barbara Eden. Just Wow.

Not too difficult to imagine they would claim that fracking disrupts the earth’s magnetic field. The Van Allen radiation belts are dependent upon a magnetic field that is powerful enough to sustain it. Once the Van Allen belts are weakened, the solar wind will blow away the atmosphere and it will be like living on Mars.

I once heard that in the Pentagon. Didn’t worry, as I was in the E Ring.

Exactly. And it’s pretty obvious that injecting a sand and water mixture into shale formations would destroy the Van Allen belts.

I like to think that this ping is "in before the moon landings denial" posts, but I didn't have the heart to check.

Read your own post....my comments were in reply to some new age nonsense you decided to spout

“I must add that this is a big part of the “New age movement”, which is really just Buddhism for westerners.

I first idea that we are all connected by this “energy field” and the second that we are all gods.”

In case you are to lazy to check your own post...the above is what your posted. My comments are more than justified

In no way did I suggest that I agreed with that “New Age” NON-Science, I was simply pointing out how they use this stuff to advance their movement.
