20 Nov 02 - 10:03 PM (#831270) Subject: RE: BS: Black holes collide From: Bobert Danged, and to think I've been worried about George Bush? Silly me... Ahhhh, any math wizzards out there? Okay a black hole is like negative numbers, right? So if two of 'em hook up do they create matter? Or twice as much anti-matter? PM me for the correct answer... Bobert |
|
20 Nov 02 - 10:15 PM (#831277) Subject: RE: BS: Black holes collide From: Amos It is not a matter of anti-matter. It is a matter of matter, but made so dense that its gravitational pull is phenomenal. Two of them colliding will cause perturbations all across the frequency spectrum, but it is debatable how much of what would actually escape. Ripples in the fabric? Well at least, ripples in the gravity field. Anti-matter is something else again, rarer by far than black holes. Or so it seems. A |

20 Nov 02 - 10:26 PM (#831287) Subject: RE: BS: Black holes collide From: Bobert First of all Amos, Iz gon on record of sayin' that I did *not* have sex with that "perturbation". With that said, nice guess but like guesses tend to be (the bobert yawns) just.... a guess. Bobert |

21 Nov 02 - 11:17 AM (#831673) Subject: RE: BS: Black holes collide From: MMario well - the thang about a black hole is that the gravity is so intense that not even photons escape - so wouldn't expect much except the "ripples in the gravity field" to be observable. |

21 Nov 02 - 11:28 AM (#831683) Subject: RE: BS: Black holes collide From: mooman Amos, Shouldn't there theoretically be as much antimatter as matter? Perhaps we just haven't found it so far? Thanks for the link Michael! mooman |

21 Nov 02 - 11:28 AM (#831684) Subject: RE: BS: Black holes collide From: MMario well - forgot the x-rays, etc; but visibly not much would happen. |

21 Nov 02 - 11:35 AM (#831690) Subject: RE: BS: Black holes collide From: Amos Mooman -- Actually, that might be the key to the pesky question of what could possibly cause a big bang!! Universes in collision, one of matter, one of antimatter. Kaboom!! So we only see the amount that got leaked in to our share of the aftermath. THe rest is all in the next universe over, the one Lewis Carroll and Gary Larsen and a few Mudcat denizens are secretly from... :>) A |

21 Nov 02 - 01:12 PM (#831790) Subject: RE: BS: Black holes collide From: Don Firth Makes ya feel kinda small, donit? In Astronomy 101, the prof says, "The sun will have used up all its fuel about five to seven billion years from now, and when that happens, it will swell into a red giant, expanding well beyond the orbit of earth before it finally collapses into a white dwarf." A hand goes up in the back row. "Yes?" says the prof. "You have a question.?" "Yes. How long did you say it would be before that happens?" "Five to seven billion years." "Oh, thank God! I thought you said million!!" Don Firth |

21 Nov 02 - 07:38 PM (#832068) Subject: RE: BS: Black holes collide From: michaelr What intrigues me is this: -- Those black holes are 400 million lightyears away. -- They appear to be 100 million years from collision. -- That means the collision already happened... 300 million years ago. Se we're not going to see anything happen. But what about that "gravitational ripple" effect? Would that spread at the speed of light? Faster? Slower? Michael |
|
21 Nov 02 - 07:45 PM (#832070) Subject: RE: BS: Black holes collide From: Bobert Well, danged, Micheal. It's not like there a lot of light out there in space, so me and the Wes Ginny slide rule figure that the "ripple" will get be slowed considerably by the *speed of darkness*... Bobert |

Nevermind yer funny little chickenface there; Daryl Beano Ratting Oort of yer Grey Alien friends, yuh heeeah? I mean, just because yer the House FizzyCyst dozen give yez License to Chill, yer know?
