Blast from the Past

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

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 .
A 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 .
