Gamma ray bursts, not a natural occurrence, but a weapon

Let's talk about GRB's

They come from nowhere, in the middle of the abyss, with no known origin, no explanation, and with more power than our own stars

Now this might be harder for people to understand, but we have harnessed the energy of the sun on our own planet when we've generated star in jars, and super-powerful weapons like that might not be entirely unrealistic to think of

If we had to develop a nuclear weapon for example, it'd be useless against one of those planet sized spheres

A gamma ray burst could easily rip one in half though, and could explain their weird origin and purpose

This could very well be us witnessing at long range, a weapon being utilized by another species so dramatically powerful (I'd assume this capability from species able to traverse the stars, and the amount of fundamental power required to do that constantly would be absurd to put in perspective)

It's the matter of the origin, not always coming from NOVA's that makes them suspicious, these are supposed to straight up appear out of thin air (void?) from virtually nowhere, so much so that people believe they might be white holes or something bursting from a worm hole

That can't be accurate though, that would be fairly noticeable to us overall, and they've never shown any evidence of actually stemming from things like stars

These things appear to actually be an energy weapon being utilized to utterly vaporize an enemy force when drastic measures must be taken, and whoever utilizes them has virtually no desire to care about what's on the other side, and they don't care what direction these fire off at, considering earth was narrowly avoided in just 2013 by one of these stray tungsten rod style energy beams

And one theory I have, is that these are generated with small amounts of power in order to trigger total nuclear fault in a material, releasing said blast
