Recently saw this article about a "mystery
object" surviving a "black hole" and wondered what you'd think
about it:
Why Our Galaxy's Black Hole
Didn't Eat Mystery Object
http://news.discovery.com/
For G2
to survive, Ghez has identified the mystery object as
a star embedded in a gas and dust envelope all held together under the star’s
gravity. But it’s no ordinary star.
Double
Whammy
Our galaxy is filled with binary star systems. Indeed, the sun is a rarity in that it doesn’t have a
stellar partner locked in its gravitational embrace. It’s a loner. The majority
of other stars, however, aren’t so antisocial. Binary star systems are common,
where two stars orbit one another; three or more mutually orbiting stars are
also possible.
But in
the extreme environment surrounding a supermassive
black hole, binary stars run the risk of being destabilized as they make a
close pass of the black hole’s event horizon, leading to binary mergers.
ANALYSIS:
‘Interstellar’ Black Hole is Best Black Hole in Sci-Fi
Using
the powerful 10-meter optical/infrared telescopes at the W.M. Keck Observatory
on Mauna Kea, Hawai’i, the researchers were able to study G2 in detail and
believe it is going through a million-year-long bloated period after a binary
merger. The twin Keck telescopes use adaptive optics to adjust for atmospheric
turbulence, proving astronomers with a precision view of the extreme dynamics
in the center of our galaxy.
“This
may be happening more than we thought. The stars at the center of the galaxy
are massive and mostly binaries,” said Ghez. “It’s
possible that many of the stars we’ve been watching and not understanding may
be the end product of mergers that are calm now.”
During
its close encounter, G2 certainly felt the black hole’s wrath. As the tidal
forces are so powerful at such a close proximity to Sgr
A*, the stellar gases surrounding the puffed up star are being stripped away
and becoming ‘spaghettified.’ Also, the extreme
radiation from nearby stars is heating G2′s surface, bulking out the
canopy of gas and dust that hides the star inside.

Happened
to run into this afterwards...
Wavevolution ...
"Once
they have reached one critical level of energy, lost heat as they travel and
having therefore reduced their frequencies, waves collapse, also
forming two subatomic particles with opposite charges, as if they were the
split ends of one broken hair."

This
theory strikes me as interesting - though the author comes to a lot of other
"questionable" conclusions from it...
He
also discusses the "motion" of an arrow... which brings one of Zeno's paradoxes to mind...

Excerpt
from: http://www.wavevolution.org/
How could a flying arrow appear to be standing still in a
photograph and being in Movement at the same Time?
In
relation to Time, the arrow moves through one Space which is divisible into
distinct parts: the part where the arrow occupies this position, the part where it occupies that position.
But
the instant is not so divisible.
In the precise instant of a photograph is the arrow moving or
standing still?
The
arrow seems to exist in one dichotomy of Time.
In
fact, this dilemma reveals the existence of two different dimensions, one
seemingly in evolution and marked by the rhythm of Time and also One other
which is in Stability and that transcends our dimension.
The
snapshot captures the essence of this other Dimension existing beyond Time,
Space and Movement.
Going
back to the example, in the instant of a snapshot the arrow is one. Instead, in
the course of Time (and beyond the single instant), a
Moving arrow is never the same arrow. [Heraclitus]
For
example, you are now one Existence different than you are .... now. The change
of Existence (or evolution) occurs instantly.
As far-fetched as it may sound, on each moment a different
arrow exists. Over a period of Time, an infinite number of arrows
exist even if they are all perceived as one single arrow. What we ordinarily
think of as the same object, persisting through Time, is in fact a succession
of different objects (though very similar), each one set into their unchanging
present moment. On each moment there is a different object or a different
person.
This also
eliminates the concept of Time for any sort of Existence.
If we
could capture the present, this would be here, now and without motion as in a
snapshot. The many frozen instants are like in a projector moving the film from
one snapshot to the next one. In the various instants, the components are
unique and even if similar they are never the same. How could an infinite
number of divisible points then exist inside a limited Space?
Aristotle was first to speak
about the “potential infinity” of all objects. Just like Space also Time is infinitely divisible. How
could they exist, the last moment at rest and the first moment of motion like
those of a train that starts to move from a railway station? What is in between
these two instants since also the interval is infinitely divisible?
How
could an infinite Time be contained by a limited interval?
All
this is to say that Time, Space and
Movement are only Human perceptions. [nothing original]
This
new conception could result to be puzzling because even though we seem to
persist through Time each of us is never the same. In this perspective from a
different dimension, if there is no change for us, then, what does death amount
to?
