Strange Posted February 21, 2019 Posted February 21, 2019 Good summary of the observations at the time (gravitational waves and all electromagnetic spectrum) and what has been observed since then, including a relativistic jet (confirming the creation of a black hole). Quote about 1046 atoms of gold were created, or ten quadrillion times as much as we've mined in all of human history Or about twice the mass of all the world's oceans. https://www.forbes.com/sites/startswithabang/2019/02/21/merging-neutron-stars-made-an-unstoppable-jet-and-it-moves-at-nearly-the-speed-of-light/
Mordred Posted February 22, 2019 Posted February 22, 2019 (edited) Anyone have a really big vacuum cleaner with a really long hose lol nice overview its decently done what is really cool is the added details from all the additional detection. I can see this event being studied with a swath of papers and related studies resulting from the data it found in its added details. Edited February 22, 2019 by Mordred
Raider5678 Posted February 22, 2019 Posted February 22, 2019 I remember being a kid somewhere and someone told me we would run out of gold to put in our electronics eventually.(Now that I'm older I find it unlikely) Out of curiosity, was any plutonium created? Or is that not created when stars merge?

It is in the article: Quote Almost immediately, we learned: what the masses (about 1.3 Suns) and distances (about 130 million light-years) of the neutron stars were, what they became after the merger (a rapidly spinning neutron star that collapsed to a black hole in less than a second), how much of the mass became a black hole (about 95%), and what happened to the rest of the mass (it became the heaviest elements in the periodic table, including gold, platinum, uranium and plutonium).

It also says that there was a period after the initial event where the majority of the light came from the radioactive decay of elements.

If there is created Uranium 238, there must be created trace of Plutonium 238, because one of rare decay modes of Uranium 238 is via double beta decay minus. Isotope Uranium-238 Protons 92 Neutrons 146 Mass 238.051 [u] Uranium-238 -> Thorium-234 + alpha + 4.26992 MeV Uranium-238 -> Plutonium-238 + e- + e- + Ve + Ve + 1.14415 MeV Edited February 22, 2019 by Sensei
