One long standing mystery in astronomy were the quasars.
Incomprehensible energy blasting out of a point-like source,
billions of light years away. We now know these are actively
feeding supermassive black holes, which can turn off and on in a
startlingly short period of time. Today: When black holes awaken!
Our Universe is filled with sleeping monsters. And sometimes,
whether we want it or not, they wake up hungry. In this episode,
we take a look at the science behind how and why black holes of
all sizes can go from nothing to the triggers of massive
high-energy power release.
