So far, these observations are quite uncommon, but the fact that scientists caught the interplay at all suggests such near-misses may not stay that way.
“In astronomical terms, this event is only visible to our current telescopes for a short time — about 2,000 years,” King said. “So unless we were extraordinarily lucky to have caught this one, there may be many more that we are missing.”
In case you are keeping track:
Flashy 'dance' of two monster black holes captured by NASA's Spitzer Space Telescope | Space
If two black holes tango in space but astronomers cannot see them, can we still admire their flashy dance moves?
Because black holes have such a strong gravitational pull that not even light can escape, they can't be observed directly and are therefore difficult to study. But one pair of black holes has enamored astronomers with a complicated celestial dance that periodically produces extremely bright flashes of light — outbursts that are brighter than a trillion stars and even the entire Milky Way galaxy.
How much space does a black hole take up? | Astronomy.com
The most massive supermassive black hole discovered to date lies within the Abell 85 galaxy cluster. At the heart of this cluster is the galaxy Holm 15A, home to an estimated 2 trillion solar masses. The very center of this galaxy is almost as large as the Large Magellanic Cloud, which has a radius of 7,000 light-years.
700 million light-years from Earth, this cluster was twice the distance of any previous black hole measurement when the Ludwig-Maximilians-University’s USM Wendelstein Observatory and the European Southern Observatory’s Very Large Telescope began collecting data. They found that the black hole at the center of Holm 15A clocks in at colossal 40 billion solar masses, or roughly two-thirds the mass of all the stars in the Milky Way.
Clearing up a supermassive (black hole) confusion
The interpretation of the second signature has since come under scrutiny. Using higher-resolution data from the Flemish-funded Mercator Telescope on the island of La Palma (Spain), the KU Leuven team ran several simulations and concluded that the original interpretation of the system was in fact incorrect.
"As we examined the available data more carefully, we began to realize that something didn't seem quite right" explains Michael Abdul-Masih. "The second signature did not behave as we expected it to. This is when I realized that maybe this second signature is not moving at all, but only appears to do so because of the movement of the star." "It is a little like the fake impression of moving you get while sitting in a train and the train next to you starts moving while you are not.

Why Entrepreneurs Think The EIDL Is A Black Hole
The SBA has released a report on the progress of the EIDL program. Separately, I've conducted my own survey of entrepreneurs that have applied for EIDL. Both sets of perspectives are featured below.
I've conducted research with a small group of entrepreneurs that have applied for EIDL. Forty-one entrepreneurs participated in the study. Though the sample size is not large enough to be statistically significant, there are some interesting learnings from the data.
Astronomers call for help to learn how supermassive black holes form | Astronomy.com
These black holes start small, when a galaxy is still young and regularly gobbling up groups of neighboring stars. As large stars die and collapse into black holes, those black holes consume stars and even other black holes, growing bigger and bigger as they go from small to intermediate to gigantic , like an enormous cosmic snowball.
Or that might not be how it happens at all. Instead, supermassive black holes might form from a runaway chain reaction of colliding stars , others
Hubble Finds "Missing Link" Black Hole Tearing Apart a Star That Passed Too Close [Video]
This artist’s concept depicts a cosmic homicide in action. A wayward star is being shredded by the intense gravitational pull of a black hole that contains tens of thousands of solar masses. The stellar remains are forming an accretion disk around the black hole. Flares of X-ray light from the super-heated gas disk alerted astronomers to the black hole’s location; otherwise it lurked unknown in the dark.
Astronomers have identified a black hole of an elusive class known as “intermediate-mass,” which betrayed its existence by tearing apart a wayward star that passed too close. This exciting discovery opens the door to the possibility of many more lurking undetected in the dark, waiting to be given away by a star passing too close.
An economic black hole is here — and only more spending will get us out
If you think the massive falls seen around the world are 'unprecedented' just wait until next quarter

Early economic data released on Thursday in Europe and the US is indicating a black hole, sucking everything within reach into a collapse in demand the size of which we haven't seen in 90 years -- or possibly ever (in the case of aviation and travel, for example).
