Astronomers uncover a one-in-ten-billion binary star system
- iambateman 4y agoAt astronomical scale, one-in-ten-billion still occurs billions of times in the universe. Mind boggling.
- titzer 4y agoMy first thought is that one-in-ten-billion means nothing if there are 10 billion possible states and every one is equally probable :) It totally depends on the distribution....
- ianai 4y agoSolution to the Fermi paradox: the universe can create any phenomenon attributable to life on its own. Better put: it’s near impossible to tell life from non-life at a far distance.
- perihelions 4y agoIt's pretty clever, the setup they have that found this thing. It's an *elegant* algorithmic solution to the problem, "how do you measure what angle gamma radiation is arriving from, if you can't* bend, focus, or reflect it; only block it?" https://swift.gsfc.nasa.gov/about_swift/bat_desc.html https://swift.gsfc.nasa.gov/about_swift/bat_desc.html https://en.wikipedia.org/wiki/Coded_aperture https://en.wikipedia.org/wiki/Coded_aperture
- dontwearitout 4y agoIt took me a minute to grok the pictures on that wiki page, but I love this! Super creative solution

- Maursault 4y agoSounds like kilanovas might just be the most profitable astronomical catastrophes in the Universe.
