Possible Gamma Ray Bursts in between 2012 and 2050 can extinct out civilization

The Gamma Ray Bursts (GRBs) can come from two neutron stars colliding in our galaxies or a large hypernova in our vicinity.

According to astrophysicists the burst of gamma rays from space lasting from a fraction of a second to many minutes. There is no clear scientific consensus as to their cause. Recently, their distances were determined to be large, placing the origins of the bursts in other galaxies.

According to NASA, A hypernova is a possible explanation for gamma-ray bursts. It can be thought of as a "failed supernova" -- a massive star whose core collapses but which doesn''t quite blow itself apart. The idea is that the star's core collapses because it has run out of fuel and can no longer produce enough pressure to withstand gravity. The central part of the star collapses, forming either a neutron star or a black hole. In a supernova the resulting shockwave blows off the outer parts of the star. In the case of a hypernova the shock wave doesn''t blow off the outer layers of the star. The material of the outer layers falls onto the central black hole or neutron star converting its gravitational potential energy to heat and radiation. This can result in a much higher luminosity than a supernova. This is why hypernovae were proposed as a possible explanation for gamma-ray bursts. The X-ray afterglow from a gamma ray burst has been found to be more luminous than a supernova. Whether hypernovae actually exist is still an open question.

According to some numerical simulation models, there is real possibility of GRB from two nearly colliding neutron stars. The GRM can evaporate out ozone layers or a massive part of it, wiping out our civilization between 2012 and 2050.

Not necessary to propose black holes as periodic inundation of neutrinos saturate galaxy out to position Earth, energize Fluff (gas cloud we are immersed in) which compresses our little heliosphere down to a halo of the sun, meaning all of planets are exposed to strong cosmic rays and expansion. Luckily our position is so far out it only experiences ephemeral compression and expansion. We then regain what we consider the normal heliosphere with the hotter than hell gas planets which produce weather changes in the extreme as their roiled surfaces interface with the sun.
