universetoday.com — Instead of investing in particle accelerators here on Earth, physicists might consider just blowing up a few stars. New images taken by the Chandra X-Ray Observatory show how supernova remnant Cassiopeia A acts as a natural particle accelerator, firing out cosmic rays.

I honestly thought this article was going to be about suprnova's remnants and how its accelerating torrents

I, too, was intrigued at the prospect of a former torrent website becoming a galactic entity.

The person posting this doesn't seem to understand what the article implies."Instead of investing in particle accelerators here on Earth, physicists might consider just blowing up a few stars."Yes, supernovas yield many near light speed particles, but they're so random that it wouldn't be a good source for any kind of scientific experiment. You'll never know when where or what kind of particle you'll get, or at what speed. If you're mashing particles together, this makes for very unreliable calculations. I don't recall the exact specifics, but most particles do not reach the surface of the earth.However studying the particles that do fall to the surface of the earth can display a great deal of knowledge. An emission of neutrinos allowed for the first supernova ever recorded to be observed.Studying high velocity particles is important, but don't think that they're good for a particle accelerator.

What does Tommy Lee and Jason Newstead's new band have to do with particle accela-whatever?

energized charged particles- in one form, you call it electricity.

This is hardly news. Supernova remnants have been known to be the source of very energetic cosmic rays for decades.When a supernova pops, many times the core of the old star that exploded stays in tact. It retains the angular momentium and magnetic field of the progenitor star and since it is much smaller, the stellar core spins very rapidly. The action of the magnetic field being pulled through the gas of the supernova remnant creates pulses of radio energy- hence the name pulsars.Pulsars, or neutron starts as they are sometimes called, exist in a bizaar hyper-dense state in which atoms are squashed into a neutron soup surrounded by clouds of electrons on its surface.

Isn't this just spam? Looks to me like the submitter is just talking about himself...
