Black Holes

Once
upon a time people thought that black hole physics was too fantastic to be true.
And now they are centre stage. We now know they dominate the evolution of
the universe itself.
It is currently thought that black holes are the result of what happens when
stars run out of
fuel and collapse under their own weight. But nobody is really sure because black holes are where the accepted laws of
physics break
down.
The effect of the
mass is still in our
universe, causing a fold in space, that
goes 'all the way down'.

Our
black hole is in the
constellation Sagitarrius in the centre of
the milky way and has an estimated
mass of approximately 4 million stars.
It must have
swallowed millions of stars since it's beginning as a cosmic sinkhole.
A
black hole is a 'deep well' in
space time.
When two black holes meet - the smaller one circles the big one -
like a spirograph in a very defined pattern, which looks like the same rotation
of the protons and electrons.
It is a point of infinite density. A region where time
and space have closed in on itself. Where the pull of
gravity is so
immense that neither
light nor
matter can come out once it has entered.
We know of them now, proven in 197X, but back when it was just a theory -
Einstein rejected the idea.
Right now, our nearest
galaxy (Andromeda)
is
charging towards us (billions of years away).
Heliosphere (reference)
Sometimes when a star goes supernova it is so massive that it doesn`t even
create a neutron star. Nothing keeps it from collapsing right down into a
black hole.
Some bigger than others.
Micro Black Holes are about
the size of a Proton and disappear billionths of a
second after they ``become``.
The most massive eruption we know of happens at a black hole.
Biggest
known has lasted 100M years and still going.
The biggest Black Holes we know of are known as NGC 3842, the brightest galaxy
in the Leo cluster of galaxies nearly 320 million light years distant, has a
central black hole 9.7 billion solar masses large. The other, named NGC 4889,
the brightest galaxy in the Coma cluster more than 335 million light years away,
has a black hole of comparable or larger mass. Both encompass regions or "event
horizons" about five times the distance from the sun to Pluto.
"For comparison, these black holes are 2,500 times as massive as the black hole
at the center of the Milky Way galaxy, whose event horizon is one-fifth the
orbit of Mercury," said study lead author Nicholas McConnell at the University
of California, Berkeley.

Quasars
Quasars
blast away huge quantities of gas from the surrounding galaxy. The
equivalent of 10 earths every minute.
Black holes suck gas in,
Quasars
blow it out.
Probably every big
galaxy was
a quasar
when it was young.
Quasars -- short for quasi-stellar objects -- are glowing discs of matter that
orbit supermassive black holes, heating up and emitting extremely bright
radiation as they do so.
"A quasar accretion disc has a typical size of a few light-days, or around 100
billion kilometres across, but they lie billions of light-years away.
This means their apparent size when viewed from Earth is so small that we will
probably never have a telescope powerful enough to see their structure
directly," explains Jose Muñoz, the lead scientist in this study.
Until now, the minute apparent size of quasars has meant that most of our
knowledge of their inner structure has been based on theoretical extrapolations,
rather than direct observations.
Birth of Famous Black Hole: Longstanding Mysteries About Object Called Cygnus
X-1 Unraveled
ScienceDaily (Nov. 17, 2011) — For the
first time, astronomers have produced a complete description of a black
hole, a concentration of mass so dense that not even light can escape its
powerful gravitational pull. Their precise measurements have allowed them to
reconstruct the history of the object from its birth some six million years
ago.
ScienceDaily
(Aug. 29, 2012) —
NASA's Wide-field Infrared Survey Explorer (WISE) mission has led to a
bonanza of newfound supermassive black holes and extreme galaxies called
hot DOGs, or dust-obscured galaxies.
Black
Holes Spin Faster and Faster
ScienceDaily (May 23, 2011)
— Two UK astronomers have found that the giant black holes in the centre of
galaxies are on average spinning faster than at any time in the history of
the Universe. Dr Alejo Martinez-Sansigre of the University of Portsmouth and
Prof. Steve Rawlings of the University of Oxford made the new discovery by
using radio, optical and X-ray data. They publish their findings in the
journal Monthly Notices of the Royal Astronomical Society.
