| Igneous Magma Posts: 169 | The following story got me thinking about how important can our worrying about our VALUE in the universe be when a cosmic event could eliminate us in an instant. It makes worrying about evolution-creationism, war, human behavior, or afterlife a complete waste of time. Party on!! Black Hole Seen Ripping Star Apart PASADENA, Calif. (AP) - Two space observatories have provided the first strong evidence of a supermassive black hole stretching, tearing apart and partially gobbling up a star flung into reach of its enormous gravity, astronomers said Wednesday. The event had long been predicted by theory but never confirmed. A powerful X-ray blast drew the attention of astronomers to the event, located near the center of a galaxy about 700 million light-years from Earth. The international team of astronomers believe gases from the star, heated to multimillion-degree temperatures as they fell toward the black hole near the heart of galaxy RX J1242-11, produced the blast. Astronomers said a star about the size of our sun neared the black hole after veering off course following a close encounter with another star. The tremendous gravity of the black hole, estimated to have a mass 100 million times that of our sun, then stretched the star to the point of breaking. "This is the ultimate David versus Goliath battle, but here David loses," said Gunther Hasinger, of the Max Planck Institute for Extraterrestrial Physics in Germany. The effect is the same that the tug of the moon has on the Earth's oceans, but with much more violent results. The black hole consumed an estimated 1 percent of the doomed star, flinging the rest out into space. "This unlucky star just wandered into the wrong neighborhood," said Stefanie Komossa, also of the Max Planck Institute. Astronomers used NASA's Chandra and the European Space Agency's XMM-Newton X-ray observatories to capture the event. Similar events are estimated to occur just once every 10,000 years in a typical galaxy. Astronomers have seen other similar X-ray blasts before, but never were able to pinpoint them at the center of a galaxy, where black holes lurk. The new observations also revealed the characteristic X-ray signature expected of the surroundings of a black hole. The blast first was seen in 1992 and remains visible as it fades, said Chandra press scientist Peter Edmonds, of the Harvard-Smithsonian Center for Astrophysics. |

![]() Neo Moderator Location: England Posts: 5,471 | This is more of a science type thread...hmm. Anyway, I've known about these possibilities long ago, latest estimates show that we're thousands of light years from the nearest black hole (Cygnus X-1). Although if one did appear near this solar system there'd be bugger all we could do about it, we're not ready for vast space colonisation to escape. You should also know that a nearby supernova occurence could sterilise this planet, so could the collision between two orbiting neutron stars. Ah Space, what a nice lethal place. War is Peace Freedom is Slavery Ignorance is strength Harness the power of Ingsoc, then you can capture someone killed the year before |

But I don't think instant death will result in better karma :). I think that karma is a way to teach us, and we have to be alive to learn. |

| Igneous Magma Location: London baby, yeah! Posts: 198 | What you didn't mention is the amount of time it takes for one of those things to do its business, and for a star it's in the order of 10^6-9 years(approx. millions or billions of years). And seeing as one isn't around now, your safe. We'll all be dead in the next few thousand years anyway. A man has two reasons for doing anything --- a good reason and the real reason. Let us be thankful for the fools. But for them the rest of us could not succeed In spite of the cost of living, it's still popular. |

| Hot Lava Posts: 1,859 | super compact matter colliding on itself until big bang... eternal recurrence... deja vu? "I really like this jacket, but the sleeves are much too long..." insanity is doing the same thing over and over again, but expecting different results... |
