Gamma Ray Bursts are instantaneously most luminous and energetic objects in the Universe.
Thought to represent the birth cry of a distant, stellar mass (~few solar masses) black hole, formed in the death throes of a massive star, these powerful explosions are also the most distant, found out to the edges of the observable Universe. Discovered in the late 1960s, GRBs now represent a major research area in modern astrophysics. I will summarise our understanding of these remarkable objects and present state-of-the-art observations made with novel robotic telescopes that aim to determine the physics of their ultra-relativistic ejecta and the role of magnetic fields in accelerating and collimating these outflows. Beyond their astrophysical interest, I will speculate on their use a probes of theories of fundamental physics.
