Black Holes Supply Lifeblood for Galaxies

Universe Today reported Black Holes Supply Lifeblood for Galaxies.

"These scientists say the powerful black holes at the center of massive galaxies act as hearts to the systems, pumping energy out at regular intervals to regulate the growth of the black holes themselves, as well as star formation. ‘Just like our hearts periodically pump our circulatory systems to keep us alive, black holes give galaxies a vital warm component. They are a careful creation of nature, allowing a galaxy to maintain a fragile equilibrium,’ said Alexis Finoguenov, of the Max-Planck Institute for Extraterrestrial Physics in Germany."

See, your heart is like a black hole.

How can someone not have commented on your snarky cardio-anthropomorphism. There's a pop lyric in there somewhere.
