Synopsis :
A kiloNova at our galactic core would sterilize Earth . This could happen this year .
Discussion :
1. Sgr A* and the newly discovered magnetic neutron star, SGR J1745-29, which appears to be in orbit around the black hole, are dishing out lots of interesting science, See Appendix B .
2.There “is” a gas cloud spiralling into Sgr A*  . See Appendix B . The lightspeed results are becoming visible now .

3.Enormous magnetic fields are created , spiralling around the jets from the black hole .
4.These interact with the magnetic neutron star SGR J1745-29 , influencing its orbit . The geometry of field-strengths means that the neutron star will start spiralling into the black hole . Time – unknown .
5.The collision of a black hole and neutron star is a KiloNova . See Appendix A
This energy release will sterilize a good portion of the galaxy , even outside any jets .
6. See Appendix C . This was expected earlier , but things have been delayed by the magnetic neutron star interacting with gas cloud . (Momentum transference via magnetic fields . Strong x-ray bursts to be expected)
7. Nothing says goodbye like a Gamma Ray Burst .

Celestial mergers between black holes and super-dense neutron stars could produce short-lived gamma-ray explosions in space and can explain the origin of chemical elements such as gold and platinum, scientists said.
The latest discovery, which appeared in a special online edition of the journal Nature on Saturday, was made based on last month’s observations by NASA's Hubble Space Telescope. The Hubble detected a fading fireball from a new kind of stellar blast called a “kilonova,” an incident that was followed by a brief short gamma-ray burst, or GRB, in a galaxy almost four billion light-years from Earth.
Scientists said that a kilonova has long been predicted by astronomers to accompany a short-duration GRB but had not been seen until now. Such an explosion is so powerful that it can be 1,000 times brighter than a typical star explosion, called a nova. On the other hand, a typical supernova, the self-detonation of a massive star, could be 100 times brighter than a kilonova.
“Many astronomers, including our group, have already provided a great deal of evidence that long-duration gamma-ray bursts (those lasting more than two seconds) are produced by the collapse of extremely massive stars,” said Nial Tanvir of the University of Leicester in the United Kingdom, the study's lead author, in astatement.

Watching for a black hole to gobble up a gas cloud: Gas cloud's fate illuminates growth of supermassive black holes
April 4, 2014
Northwestern University
G2, a doomed gas cloud, is edging closer to Sgr A*, the hungry supermassive black hole at the Milky Way's center The closest approach between the two is predicted to occur any day now. Astrophysicists have been watching closely, and the data do not show enhanced emission in the X-rays.
"Sgr A* and the newly discovered magnetic neutron star, SGR J1745-29, which appears to be in orbit around the black hole, are dishing out lots of interesting science," Haggard said. "We've detected the brightest X-ray flare yet observed from Sgr A* and gathered data that are causing us to overhaul of our understanding of the neutron star population in the galactic center."

Blast from the Past

Blast from the Past
Andre Willers
13 Jan 2012

High intensities of gamma- and X-ray radiation on Earth from the center of our galaxy can be expected during 2013 AD , due to an infalling gas cloud into the central Milky Way black hole .

Discussion :
The discovery was made by Stefan Gillesson of the Max Planck Institute for Extraterrestrial Physics
in Garching , Germany .

2. “New Scientist” 17 Dec 2011 p16 “Cloud suicide could transform black hole”

A gas cloud of an estimated three earth masses is expected to impact the supermassive , rotating black hole at the center of our galaxy (“Sagittarius A*”) in 2013 AD . Note that radiation from this event can be expected shortly afterward in local time .

large part of this mass will be converted to electro-magnetic energy .

Now , three earth masses is not a lot of energy in the galactic scheme of things , but the way it is distributed does .

Briefly , the energy release is characterized by very short wavelenghts (gamma or x-ray) and lobe-shaped distributions of the pulse-wavefronts in the galactic ecliptic .

There is a combination of relativistic and quantum effects in the last few cm's before the event horizon .

1.There is a slingshot effect , because the gas cloud must be lumpy , even if only at atomic scale . The gas cloud vanishes in a few Planck -time units , emitting very short-wave radiation due to differential tidal friction .

2.But the black hole is large and rotating , which forms time-bands of slower time , which gives enough time for feedback . Depending on the size and rotation speed of the black hole , this will lead to 2n lobes of wavefronts on the rotation equator , where n=1,2,3,...

3.Hawking Burps .
This process in para 2 above “foams” the event horizon , leading to a drastically increased Hawking radiation . (The “foam” would be something like Sierpinsky chaotic triangles)
The density and time-band concentrations of energy separates particle-anti-particle pairs to give Hawking radiation .

This burp of energy sweeps matter from the neighborhood of the black hole and reduces the mass of the black hole , preventing black holes from swallowing everything . Elegant .

4.Turning a Hawking Burp into a White Hole .
There is a narrow window where the Burp becomes self-sustaining . A large black hole then evaporates in an awesome release of energy . Even the tiniest random fluctuation (eg matter-antimatter) will get magnified and perpetuated .
Not the place to take your mother for a picnic .

5.Foaming Space-time .
Well , space-time is already foamed , but only to a simple level . (Quantum foam)
Call it Foam(0)
We can churn this to higher orders of foam (Foam(1) , Foam(2) , Foam(3) ,...,Foam(b) )
where b can be derived from Kantor's Aleph classes combined with chaos theory .

Taken to the logical extreme , this leaves only Foam ordered into Branes .

The smile on the Cheshire cat just after he brushed his teeth .

So what does this mean to us ?
A full frontal impact from a lobe will give a definitive answer to Fermi's Paradox : “Where are they ?” Why , extinct .

More likely is an immersion in the higher radiation levels alongside the lobes for a long time .
Can be survived , given enough warning .

Friday the thirteenth can be quite a gas .
