What causes the short-lived, highly energetic, flash of light emitted by some
black holes as they are created?
black holes as they are created?
Entropy said:Its a hypernova (massive star collapsing directly into a black hole) with its jets pointed right at us.
kurious said:How do very densely packed photons prevent each other from escaping?
Judging by what has been observed so far, no. IIRC, some polarisation has been observed - in both optical and gamma regimes? - in one or two long GRBs, but no coherent photons. Of course, once a lot more GRBs have been carefully observed ...kurious said:Could gamma ray bursters be coherent photon producers like lasers - hence their great energy output? This would imply that the source star has some sort of
cavity in it for resonance perhaps? Or cavities if there are lots of wavelengths emitted.
sol2 said:In terms of the Bose Nova, the "jets" might be negative energy that can be utilized for space travel in the dynamics of the universe?
If we saw such a collapse, let's say in terms of the Heisenberg Collapsing sphere, the geometrical consistancy might have made itself known?
I had looked at early information here in regards to the A bomb and was wondering if Heisenberg actually saw more then anyone at the time?
I'm still at a loss sol2 - first you talk about BECs, then make a cryptic reference to magnetic fields and GPB, and link to a post about x-rays from the Milky Way centre, which itself has links to a strange site on M Theory.sol2 said:Nereid,
Surely the https://www.physicsforums.com/showthread.php?goto=newpost&t=37841 itself would reveal information?
You have to encapsulate what the magnetic field is doing, and then look beyond this? Why I have referred to grvaity probe B, as something more then just looking at radiation interaction of Glast

You seem to be saying that observational footprints of quantum gravity may be seen in GRBs, but so far it's all hand-waving (of just about the worst kind - vague allusions and mashed up experiments/theories/speculation) ... please show that there's some OOM reason to think that!sol2 said:From theories you do not understand? When's the last time you have joined comological events to quantum mechanics and tried to develope the relationship to quantum geometry?
If you unit electromagnetism with gravity, what would you get? What would 4d of space look like?
From that perspective, the early event would have revealled information, one in the scattering as Glast shows us and another in regards to the strength of the gravitons?
Graviton shroud?
I guess that's it.

Gamma ray bursts are extremely energetic flashes of gamma rays, the most powerful form of electromagnetic radiation, that are emitted from distant galaxies. They are some of the most energetic events in the universe, releasing as much energy in a few seconds as the sun does in its entire lifetime.
The exact cause of gamma ray bursts is still unknown, but they are believed to be the result of two neutron stars or a neutron star and a black hole merging, or a massive star collapsing into a black hole.
Most gamma ray bursts last for only a few seconds, although some have been known to last for several minutes. However, the afterglow of a GRB can be observed for days or even weeks after the initial burst.
Despite their immense energy, gamma ray bursts are not believed to pose a threat to Earth. They occur very far away from our planet and the Earth's atmosphere provides protection from their harmful effects.
Scientists use a variety of instruments and techniques to study gamma ray bursts, including ground-based telescopes, space-based telescopes, and detectors on satellites. They also use computer simulations and models to better understand the physics of these powerful events.
