Some 900 million years ago, a black hole released a terrible belch that echoed through the cosmos. On August 14, the resulting ripples in the fabric of spacetime passed through Earth—giving us the best evidence yet of a never-before-seen type of cosmic collision that could offer new insights on how the universe works.

The detection, called S190814bv, was likely triggered by the merger of a black hole and a neutron star, the ultra-dense leftovers of an exploded star. Though astronomers have long expected such binary systems to exist, they’ve never been seen by telescopes scanning the heavens for different wavelengths of light. (See the first image of a black hole's silhouette, made using a gigantic array of radio telescopes.)

I just cannot wrap my head around how something that happened 900 million years ago is just now hitting Earth.

Some scientists think this may have been a PacMan black hole roaming around - intriguing

<<Scientists have never detected a black hole smaller than five solar masses or a neutron star larger than about 2.5 times the mass of our Sun.

‘Based on this experience, we’re very confident that we’ve just detected a black hole gobbling up a neutron star. However, there is the slight but intriguing possibility that the swallowed object was a very light black hole - much lighter than any other black hole we know about in the universe. That would be a truly awesome consolation prize.>>

So since Kip Thorne and Stephen Hawking made a bet about the "binary" in Cygnus X-1 being a black hole nigh on 50 years ago...black holes have gone from a fringe mathematical oddity in the relativity solution set...to quite possibilty being one of the most significant physical drivers in galaxy/universe/(life??) shaping.....across a truly phenomenal range of sizes....

wonder if the other symmetrical oddity "white holes" will ever make a similar journey...
