Black holes heat up the universe

(May 15, 2012) — Astrophysicists have just discovered a new heating source in cosmological structure formation. Until now, astrophysicists thought that super-massive black holes could only influence their immediate surroundings. A collaboration of scientists at the Heidelberg Institute for Theoretical Studies (HITS) and in Canada and the US have now discovered that diffuse gas in the universe can absorb luminous gamma-ray emission from black holes, heating it up strongly. This surprising result has important implications for the formation of structures in the universe.

Intersting... could this be

Intersting... could this be also related to the cosmic background radiation?... if so we may have to look up again into the standard BB theory. 

"I once prayed to god for a bike, but quickly found out he didnt work that I stole a bike and prayed for his forgiveness"

"All matter originates and exists only by virtue of a force... We must assume behind this force the existence of a conscious and intelligent Mind. This Mind is the matrix of all matter." (Max Planck)

"the existence of mind in some organism on some planet in the universe is surely a fact of fundamental significance. Through conscious beings the universe has generated self-awareness. This can be no trivial detail, no minor byproduct of mindless, purposeless forces. We are truly meant to be here." Paul Davies
