The researchers think the black hole erupted twice because it
consumed two separate meals. The reason for this might lie with the fact
that the galaxy it's in had collided with another galaxy nearby. This
would provide plenty of cosmic gas on which a black hole could feast.
"There's
a stream of stars and gas connecting these two galaxies. That collision
led gas to stream towards the supermassive black hole and feed it two
separate meals that led to these two separate burps," said the
University of Colorado researcher.
Qigong master Chunyi Lin said there is a harmony to the universe - even with these colliding galaxies - now we know why!
The observations are important because they support previous theories
- not demonstrated until now - that black holes should go through these
cycles. The black holes were expected to become very bright in the
process of feasting and burping and then go dark during the nap phase.
"Theory
predicted that black holes should flicker on and off very quickly and
this galaxy's evidence of black holes does flicker on timescales of
100,000 years - which is long in human timescales, but in cosmological
timescales is very fast," said Julie Comerford.

Astrophysicist Paul S. Wesson figured out the truth - black holes (and the Big Bang) are "smooth" - harmonic cycles
