Great stuff Ebidah, thanks! Quoting: hey 395526
Anytime OP :)
I just finished reading Earth under fire by LaViolette, very cool book i thought. |

Earth Under Fire, I'll check into it, again thanks. Maybe there is a connection with the GRB's and the ear ringing people are experiencing...gravity wave? The surfs up I guess! |

cbs had a gamma ray burst story
[link to www.cbsnews.com]
Gamma ray bursts are the most powerful events in the universe, exceeded only by the cosmic curtain-raising Big Bang itself. Lasting just a few seconds on average, the bursts appear out of nowhere like flashlight beams and are thought to signal the formation of black holes.
(THOUGHT TO >> means they don't know!)
Astronomers theorize the collapse or collision of massive stars is what produces black holes - so dense not even light can escape - and that the resulting gravitational energy sends gamma rays shooting out across time and space.
"We think that, perhaps, bursts are the birth cries of black holes and we're seeing these throughout the universe," said NASA's Neil Gehrels, principal scientist.
A single gamma ray burst releases more energy than the sun will emit in its entire lifetime at all wavelengths, Gehrels said.
Put another mind-blowing way, "If you added together everything in the rest of the universe during that second, it would not be as bright as the gamma ray burst," said Pennsylvania State University astrophysicist John Nousek, director of mission operations.
So far, astronomers have managed to identify only a couple dozen gamma ray bursts, as close as a few million light years and as far as 12 billion light years. Swift should zero in on two gamma ray bursts a week as far away as 15 billion light years, representing the very first generation of stars, for a grand total of more than 200 during the planned two-year mission.
The spacecraft will scan one-sixth of the sky at any one time and thus see one-sixth of all gamma ray bursts out there. The observations will help scientists learn more about what the bursts are, how black holes are formed and how many are out there.
As soon as Swift's gamma ray burst-alert instrument spots an explosion, the spacecraft will quickly turn all by itself so that two other on-board telescopes can observe the X rays and ultraviolet and optical light streaming from the afterglow.
This swinging into position will take just a minute, lightning speed by astronomical standards because of Swift's six momentum wheels, double the usual number for a science satellite. Speed is crucial because once the ever-so-brief gamma ray burst subsides, the afterglow is difficult to find and fades within hours or sometimes weeks.
News of the gamma ray burst and its precise location instantly will be relayed to astronomers everywhere by the mission control center at Penn State. Ground observatories can then be aimed to assist in the afterglow analysis.
Deputy project manager Tim Gehringer calls Swift "the roadrunner of spacecraft, speeding from birth to birth as it advances mankind's knowledge of the most violent explosions in the universe."
Scientists are quick to point out that military spy satellites may well exceed Swift's swiftness. On the scientific front, though, this rapid-response observatory has no peer.
Until now, 15 minutes was considered "really fast" for a space observatory and its team to respond to a late-breaking astronomical event, said Anne Kinney, director of NASA's universe division. Swift "is a completely different level of fastness, one minute, one minute and designed to do that consistently, not dependent on anybody answering their cell phone," she said.
The Hubble Space Telescope, by contrast, takes hours if not an entire day or two to swivel into an impromptu viewing position.
After chasing gamma ray bursts for a year or two, Swift will expand its repertoire to other rapidly occurring cosmic events.
"If you want to see something like that," Nousek said, snapping his fingers, "who you going to call? Swift is the people to call." |

Are they detecting GRBs that are just now happening or are they detecting ones that are now reaching earth? |

I don't know. Swift sees them "out there" is my impression. |

there is a book {science fiction} its called Decipherd by Stel Pavour and a lot of the myth and science stuff is talked about in circles. But anyways in the book he talks about Tesla effect talking about resonance and a connection between gravity waves |

how long does it take for the effects to hit earth?
there was a huge GRB three or four days before the 9.2 EQ that caused the Indonesia tsunami Quoting: Anonymous Coward 170917
Thats been discounted, there is no proof of any relation between the two. I checked into it, was a nice theory but it went bust. There is no connection. |

perhaps we are seeing more because we have better instrumentation to find these gamma bursts? How long has Swift been operational? I didnt think it was that long ago.
Just because we are now measuring and seeing many in one day doesnt mean that this hasnt been happening all along... |

And the recorded times are spread out enough so that most of the earth will get pinged instead of just the "exposed" side. |

"caused the Indonesia tsunami" ? Bullshit, you don't have the slightest clue what you are talking about.
that was not my opinion, it is from an article that I read.
I leave those matters to the scientists, are you one? Quoting: Anonymous Coward 170917
Interesting, cuz this could be the Earth (geocentric) signal of the trinity event acolyte was talking about (19-20 MARCH) on her thread. Bears watchin'... Wasayo |

Really? and you do? Actually it would have been the gravity wave that travels faster than light that arrived before the grb that would be the suspect. |

Well, if the theory of a terrestrial effect is true, than the theory that a gamma burst follows a gravity wave, means that if we see a gamma burst then the gravity wave has already passed and so... if we havent experienced an earthquake by the time we see the gamma burst then we wont.... in theory anyway. |

Good question. I dont even think they've been able to focus in on the exact spot where they burst. They are trying but havent yet. It seems the problem is if you dont zoom in on them right away it is impossible to find them from their diminishing glow. So far scentists only theorize what these gamma bursts (and unproven gravity waves) really are, and are calculating their distances based on a theoretical math model of the total energy released. Even assuming they come from outsde our own galaxy, math models suggest that even ONE gamma burst is more powerful than ALL the remaining energy in the universe?????
I would suspect that something aint quit right about that... But we are dealing in the weird world of black holes, and something isnt quite right about them either. |
