Caturday’s Astrophenia | Black Hole Rhythm & Blues


Screen Shot 2015-11-20 at 21.10.01

G’day! I hope this day finds you all in good spirits. I’m listening to a debate (again!) as I type this entry, which ought to pop up on this site by 20:00 EST this Caturday. Things have been busy but acceptable, and that’s alright. This week marks in physics history the second time the LIGO experiment has picked up gravitational waves, the song of the Cosmos, the result of a merger of two more black holes about 1.5 billion years ago and the same in lightyears of distance. That’s a good thing considering the effects on anything in the vicinity of the merger, particularly instant of the two black holes becoming one. So, it’s back to the books, safe in the knowledge that this event, while darned awesome and fun to think about, is safely distant, both in space and time, but knowable to we fortunate humans at this lucky moment of our exploration of the universe.
