What are gamma ray bursts?


Question asked by: knowitall

Gamma ray bursts are one of the current mysteries that is still to be explained.

Basically, if we could see gamma ray wavelengths, we'd see the sky glow - and much of this is from known sources like pulsars, quasars and so on.

However, from time to time we have directly observed sudden pulses of gamma rays for a few seconds at a time.

These pulses pour out massive energy.

The mystery is with regard the source of these gamma rays - what is the event that causes all that energy to be given out?
