First, what are they?
Cosmic rays are charged subatomic particles that streak to Earth from deep in outer space. A few rare cosmic rays are extraordinarily powerful, with energies up to 100 million times greater than any attained by human-made particle colliders, such as CERN's Large Hadron Collider. The sources of these cosmic rays are a mystery. http://www.space.com/15323-cosmic-ray-mystery-unsolved.html (Believe it or not, the following might be good news: ~Jeanniebean) New evidence may now rule out gamma-ray bursts as sources of these ultra-high-energy cosmic rays. Instead of gamma-ray bursts, researchers note that black holes at the centers or nuclei of active galaxies may be responsible for these ultra-high-energy cosmic rays, sucking in matter and spitting out enormous particle jets as they gorge. How to determine from where these cosmic Rays came from.

Auger Observatory closes in on long standing mystery, links highest-energy cosmic rays with violent black holes
Scientists of the Pierre Auger Collaboration announced today (8 Nov. 2007) that active galactic nuclei are the most likely candidate for the source of the highest-energy cosmic rays that hit Earth. Using the Pierre Auger Observatory in Argentina, the largest cosmic-ray observatory in the world, a team of scientists from 17 countries found that the sources of the highest-energy particles are not distributed uniformly across the sky. Instead, the Auger results link the origins of these mysterious particles to the locations of nearby galaxies that have active nuclei in their centers. The results appear in the Nov. 9 issue of the journal Science. Active Galactic Nuclei (AGN) are thought to be powered by supermassive black holes that are devouring large amounts of matter. They have long been considered sites where high-energy particle production might take place. They swallow gas, dust and other matter from their host galaxies and spew out particles and energy. While most galaxies have black holes at their center, only a fraction of all galaxies have an AGN. The exact mechanism of how AGNs can accelerate particles to energies 100 million times higher than the most powerful particle accelerator on Earth is still a mystery. http://www.auger.org/news/PRagn/AGN_correlation.html **************************** I still have not found any theories concerning what effect these cosmic rays have on the earth. |

What number Ray Screen do I need to get?
I keep forgetting to ask. Is that a dial phone you have on yer ear? |

I keep forgetting to ask. Is that a dial phone you have on yer ear? It is a desk phone I ordered via the Internet. It has buttons for dialing on the body of the phone. I don't like these cheap wireless phones with all the buttons on the headset, so I ordered a desk phone for my desk. |

When in doubt consult wikipedia.
Note: My personal feeling is that these high energy cosmic rays are not harmful but that they have the power to alter our DNA. This is what wikipedia said: Human health effects
The potential acute and chronic health effects of space radiation, as with other ionizing radiation exposures, involve both direct damage to DNA and indirect effects due to generation of reactive oxygen species. Acute (or early radiation) effects result from high radiation doses, and these are most likely to occur after solar particle events (SPEs).[12] Likely chronic effects of space radiation exposure include both stochastic events such as radiation carcinogenesis [13] and deterministic degenerative tissue effects. To date, however, the only pathology associated with space radiation exposure is a higher risk for radiation cataract among the astronaut corps.[14][15] The health threat depends on the flux, energy spectrum, and nuclear composition of the radiation. The flux and energy spectrum depend on a variety of factors: short-term solar weather, long-term trends (such as an apparent increase since the 1950s[16]), and position in the sun's magnetic field. These factors are incompletely understood. The Mars Radiation Environment Experiment (MARIE) was launched in 2001 in order to collect more data. Estimates are that humans unshielded in interplanetary space would receive annually roughly 400 to 900 milliSieverts (mSv) (compared to 2.4 mSv on Earth) and that a Mars mission (12 months in flight and 18 months on Mars) might expose shielded astronauts to ~500 to 1000 mSv.[16] These doses approach the 1 to 4 Sv career limits advised by the National Council on Radiation Protection and Measurements for Low Earth orbit activities. The quantitative biological effects of cosmic rays are poorly known, and are the subject of ongoing research. Several experiments, both in space and on Earth, are being carried out to evaluate the exact degree of danger. Recent[when?] experiments at Brookhaven National Laboratory's NASA Space Radiation Laboratory (NSRL) suggest that biological damage due to a given exposure is actually about half what was previously estimated: specifically, it turns out that low energy protons cause more damage than high energy ones.[citation needed] This is explained by the fact that slower particles have more time to interact with molecules in the body. Interesting: Drugs Another line of research is the development of drugs that mimic and/or enhance the body's natural capacity to repair damage caused by radiation. Some of the drugs that are being considered are retinoids, which are vitamins with antioxidant properties, and molecules that retard cell division, giving the body time to fix damage before harmful mutations can be duplicated. Question I have: (Warnng: may be a bit sci-fi) Aren't "mutations" what cause evolution? Why must any mutations be perceived as harmful? Perhaps these high energy particles are going to change our DNA so we can evolve to the next level. |

Here is how a super massive black hole eats a star for lunch.

So the cosmos gave a welcome home fireworks show on Vietnam Veteran's day, don't I feel special now!

It is a desk phone I had to order over the Internet. Companies still do use desk phones. I like desk phones. I don't lose them because they are attached to the wall. LOL
