Gamma-ray bursts are common, yet random, and fleeting events that have mystified astronomers since their discovery in the late 1960s. Many scientists say longer bursts (more than four seconds in duration) are caused by massive star explosions; shorter bursts (less than two seconds in duration) are caused by mergers of binary systems with black holes or neutron stars. This animation portrays one possible scenario that could produce the shorter bursts. While uncertainty remains, most scientists say in either scenario a new black hole is born.

neutron stars colliding are like people. if one adult an a child grab arms and spin each other, the child would spin and the adult would be stationary. this is what the sun does to earth. but, if there were two people of equal strength doing this, there would be a point when they would both be spinning, thus simulating the neutron star.
Say that a gamma-ray-burst from a hypernova 100 lightyears away from us, is heading towards the earth. The results would be dramatic. The entire planet would be sterile so to speak.
However, if gamma-rays travel at the speed of light, there would be no way for us to predict it before it hits us, right?
So thats every reason to start living right now! :)
the chances of it being pointed directly at us are slim though. and if a hypernova occurs within 100 light years of us, a grb would be the least of our worries ;D
