00:03what does the birth of a black hole look like well back in 2019 astronomers just so happened
00:09to catch that very thing in action the galaxy where it all started is called sdss 1335 plus
00:150728 and it resides some 300 million light years away and while observing it the astronomers say
00:21it suddenly lit up and in the years since it has begun glowing even brighter that means the black
00:27hole is devouring everything around it as a black hole that is not consuming material is pretty
00:31much invisible that's because when a black hole eats it creates great gravitational forces and heat
00:37all of which can be detected by our instrumentation the supermassive black hole in this scenario is
00:42around 1.5 million times the mass of our sun so what caused this black hole to suddenly wake up
00:47well astronomers aren't exactly sure what they believed happened was that its surroundings finally
00:51reached a critical mass essentially flipping a switch and awakening the supermassive black hole
00:56with the researchers saying about their investigation in the case of sdss 1335 plus 0728 we were able to
01:03observe the awakening of the massive black hole which suddenly started to feast on gas available
01:08in its surroundings becoming very bright
