That's a Mighty Big Egg

While scientists have known that supermassive black holes are always associated with giant galactic "bulges" of stars, the root of the relationship has always been a kind of "chicken-and-egg" mystery. Which came first? Well, according to this SpaceflightNow article, scientists studying a quasar more than 12 billion light years away seem to have found the answer... black holes first. Which, of course, simply moves the goalposts, as there isn't much of an answer to why the black holes form, or why a bulge of stars accumulates later on.

I'm still freaked out by the fact we can measure the gas content of an object that was twice as old as our Earth is now when our sun first turned on.
