As suggested by @Roack on this save I made, this almost looks like plasma globes, and stuff like that. The core almost looks just like the real thing, so this save is also a base-line for other saves that could be based on this idea.
Do note, that the save was also inspired by meddlepf9, hence this save:
Gamma Ray Bursts or GRBs only occur for very short amounts of time such as a few seconds. Also the beams are made of gamma rays that push all other matter away, thus forming a sort of cone shape around the beam of energy so plasma would not be in a concentrated line around the star (or what is left).
Hmm, perhaps this could be shown in slo-mo, huh?
What he said.
Anyways, I think it should be more intense. Like, if you do your reserach, you'd know that GRBs are ****ing powerful.
