They are some of the most massive explosions of energy in our universe, gamma ray bursts are powerful jets of energy that scientists are still trying to adequately explain. Their energy is in the form of high energy x-rays and gamma rays (thus the name). In recent years, many astrophysicists have come to believe that they were the powerful energy rays unleashed when a massive star collapses into a black hole, although the mechanism is still not fully understood. Still other possibilities, though.

One alternative explanation, presented originally back in the 1990's, has resurfaced in a new paper by Maxim Barkov at the University of Leeds, UK, and Serguei Komissarov of the Space Research Institute in Moscow. This explanation involves a black hole falling into the star and devouring it from the inside out. In the words of the papers' authors, from the abstract:
In this paper, we re-examine the close binary scenario allowing for the possibility of late development of accretion disks in the collapsar model and investigate the available range of mass accretion rates, black hole masses, and spins. A particularly interesting version of the binary progenitor involves merger of a WR star with an ultra-compact companion, neutron star or black hole. In this case we expect the formation of very long-lived accretion disks, that may explain the phase of shallow decay and X-ray flares observed by Swift. Similarly long-lived magnetic central engines are expected in the current single star models of LGRB progenitors due to their assumed exceptionally fast rotation.
The paper explains how this model can explain the X-ray flares observed shortly after gamma ray bursts begin, which are not explained by many of the other models. It remains to be seen if this model can also explain the other features of gamma ray burst behavior.

Blackhole quantum dots as twistters diferentiate the photon configuration for unbelievable differentiable accretion discs.Even the expanding contracting neutron star named as Heart beating neutron star amy be an intermediate evolution.the credit goes not only to Hon.Stephen Hawkings ,but also to Hon.Dr.Chandar sekahr who seeded for mass teleportation dynamics andlater for FWHM dynamics of dark matter.Further balackhole quantum dots may play avery very important role in case of blackholes quantum digital microchip designa
This is really a few questions. Does space-time have a natural equilibrium and what role do black holes play in it? Don’t all natural systems return to there ground states? If so, don’t black holes function as devices to return matter/energy back to the quantum vacuum. If so, doesn’t this by definition violate our temporal conservation laws in favour of this more fundamental space-time equilibrium-that surely must be tilted towards returning the universe back to its ground state?
This surely must be the most important question in all of physics. Current black holes theories do all thy can do to avoid it. Isn’t it time to approach the big bang and black holes from a more holistic approach?
Quasinatured Optic lattice violations at Pendulosung oscillation of diagonal between left and right side jw planes could be generated by blackhole quantum twisters from circular to quasi nature ciecular ellipsoidal combinations:
Some violent magnetic field optical lattice that operate at the first quadrant of j right and j left separates for polarization curiously at Capricorn and Cancer. Capricorn seems to be breaking magneto optic quantum sector for linear polarization and cancer for circular polarization, by diagonal oscillation of Pendulosung optic lattices. Cancer seems to be shifted more on circular polarization and Capricorn seems to be on linear polarization for earth affined dynamics and circular polarization in cancer for water affined dynamics
Fast data processing could be made with combination of circular and ellipsoidal combinations of quasi nature.Data can move down silicon fiber more quickly than through copper wire because nothing is faster than light, and light signaling offers higher bandwidth for electronic circuitry. Encoding information in the form of light pulses rather than as electric pulses allows more data to flow down a line. Kao’s principal achievement was in making the fiber more efficient; by excluding impurities in the fiber material, he developed a material that absorbed less of the light carrying signals over long distances. For this purpose he applies a low-frequency magnetic field that makes the collective spin (angular momentum) of the system oscillate. This process can be compared with the precession of a spinning top about its major axis: the deflection of the spinning top corresponds to the amplitude of the light, while the zero passage corresponds to the phase. The magnetic moments of the gas atoms are aligned in a homogenous magnetic field. The light also has a preferential direction: It is polarised, i.e. the electric field oscillates in just one direction. Under theses conditions the light and the atoms are made to interact with one another so that the light pulse emerging from the gas that is sent to Alice is “entangled” with the ensemble of 10 to the power of 12 caesium atoms located at Bob’s site.
Quasinatured resonance shifts of solar magnetic field observed as the sun moves throughLibra during Sep-oct:
Quasi natured linear to circular/ellipsoidal magnetic field emissions observed in understanding optical polarization at Libra- Aerodynamic catastrophe due to malformed combustion observed at Libra magnetic fields-reg
An interesting quasi natured arms of linear polarization mixed with circular polarization out of resonance shifting typical magnetic field may give a clue on air-fire affined catastrophe involved during combustion. This could be avoided during flight. An interesting combustion of cross resonating oscillation may be evaluated .Such a possible genetic mutation is operated in case of oct born 22 people in understanding air-fire affined explosions in space. The alternative switching from linear to circular polarization seems to be an important phenomenon at Libra, for possible digital coded emissions out of lasing.
