A new study provides a possible explanation of mysterious X-ray flares detected by the Chandra K-ray Observatory for several years in the region of Sagittarius A*, or Sgr A*. The study suggests a cloud around Sgr A*, a supermassive black hole at the center of our Milky Way Galaxy, which contains hundreds of trillions of asteroids and comets that have been stripped from their parent stars. The flares occur when asteroids of six miles or larger in radius are consumed by the black hole. An asteroid that undergoes a close encounter with another object, such as a star or planet, can be thrown into an orbit headed towards Sgr A*. If the asteroid passes within about 100 million miles of the black hole, roughly the distance between the Earth and the sun, it is torn into pieces by the tidal forces from the black hole. These fragments would then be vaporized by friction as they pass through the hot, thin gas flowing onto Sgr A*, similar to a meteor heating up and glowing as it falls through Earth's atmosphere. A flare is produced and eventually the remains of the asteroid are swallowed by the black hole. Image Credit: Illustrations: NASA/CXC/M.Weiss Read More
Motorola Droid X Review [Review]
# review Dipped in clarified cyborg testosterone as it comes off the assembly line, the Droid X is sci-fi machismo congealed into a phone. Yet it’s gelded by steroidal software—a fussy, awkward android with acne the size of asteroids. More » PlanetX-Ma Ti Sate
the world should become vegetarians? save a lot of land for grain?

You're absolutely right. His idea of an old man and a good argument for people to become vegetarians. However, I think they are addicted to meat. In your case, you need to take it easy, go on vacation thing, and leave the things you do smocking.
