Re: So here's a thought:
The speed of light is really the speed of causality: it's the fastest way any information about an event can get between any two points
That's a nice summary!
One of the explanations (in the article) of the 3 years' of X rays is the creation of a 3rd neutron star. In short, they're suggesting that, like a nuclear reaction, on a macro scale the neutron stars collided to form a "massive unstable star-particle" which then "fissioned" into multiple parts... and when you study how nuclear fission actually works, this makes for a VERY interesting analogy. Keep in mind a neutron star is a bunch of neutrons held together by massive gravity, similar to a black hole. But inside a black hole, matter is even denser and has a "6th state", sort of a non-particle "mush" containing everything that WOULD be atoms and neutrons and quarks and electrons and all of that, except it's so dense it just "mushes" and all of the borders between things go away. Or something like that.
(as I understand it, there are 6 states of matter: solid, liquid, gas, plasma, gamma, and that mushy stuff you find inside a black hole - and only the first 4 states actually keep atomic structure somewhat intact)
A neutron is (as a particle) the combination of a proton, electron, and 2 anti-neutrinos. Reason is that anti-particles and particles must balance. And so those recently-proven-to-exist neutrinos provide the anti-particles to make up the neutron. And then you crush the neutrons under high gravity, to form a neutron star, which [in theory] would really be 'neutron mush' that can still act like neutron particles [until you crush it even further into a black hole]. In a way, it's like a ginormous atom.
NOW, you combine them in a collision, not unlike nuclear fusion. The new neutron star is unstable, and splits apart. Gamma is released, and quite possibly, additional "smaller bits" (i.e. 3rd neutron star), much like what you see in atomic fission reactions, only on a lot bigger scale.
And that 3rd star now has too much kinetic energy, quite possibly spinning at close to relativistic speeds. It's a fair bet that gravity forced an inelastic collision, which means kinetic energy had to go someplace. I suspect that the 3rd star is spinning like hell, WAY too fast to be stable, and is slowing down by emitting gamma. [I also have to wonder whether or not the 3rd neutron star would actually be a black hole created by the collission, and the same point about kinetic energy and inelastic collisions]
Anyway I could be as right or wrong as anyone based on the analysis here. But it would be fun to see, if we could get up close without being X-ray'd to death.
