RT @Rainmaker1973: The first direct observation of gravitational waves captured the merging of 2 black holes which emitted 3.6 septillion yottawatts of power (3.6×10⁴⁶ watts), greater than the combined power of all light radiated by all the stars in the observable universe https://t.co/s1T5uNB2gBhttps://t.co/ezx8D1wLfm
The title is somewhat misleading in saying the event emitted x watts of power, watt only expresses the rate of energy emission after all.
The wiki says the intensity was like that for a few milliseconds, so more accurately, for a few milliseconds, the event emitted more energy than the rest of the observable universe did within that period.
The signal was named GW150914 (from "Gravitational Wave" and the date of observation 2015-09-14)
LOL: I thought we'd learned our lesson about 6-digit dates--'member Y2K?
Also, if I read it correctly, the energy released was equal to half a solar mass, meaning the same as if a quarter-solar-mass of matter and a quarter-solar-mass of antimatter annihilated each other. Or to put it another way, ~1/150th of the total mass of the 2 black holes (@29 + 35 solar masses).
