Gravitational waves produced by merging black holes

This simulation of the GW150914 event detected by the Laser Interferometer Gravitational-Wave Observatory (LIGO) at 09:51 UTC on September 14, 2015, represents the merger of a binary black hole system into a single black hole. The event is estimated to have occurred 1.3 billion years ago when two black holes (36x and 29x solar mass) merged into a single 62x solar mass with ~3x solar mass worth of energy emitted as gravitational waves.

The existence of gravitational waves was first predicted 100 years ago by Albert Einstein through his famous Theory of General Relativity. Despite being produced by all accelerating masses, the detection of these waves has eluded humanity due to their miniscule effect. The two US-based LIGO observatories use a technique called laser interferometry to detect these fluctuations in spacetime, which are as small as 10^-18 m, or about 1/1000th the diameter of a proton.

Just a few hours ago, an international team of scientists revealed that the Advanced Ligo gravity wave observation team had observed a huge gravity wave.  The event occurred when two black holes dozens of times the mass of our sun collided and joined about 1.5 billion light years away.  They believe that this opens an entirely new era in astronomy using a new information source.  Previously we have observed events and objects in the vast galaxy and universe with light waves and electromagnetic signals reaching us.   Gravity waves will tell us much more about the black holes that are at the center of most every galaxy in the universe.   The waves will also enable us to understand violent events at the center of stars much better with new kinds of information hardly imaginable.   I'll be adding more links to this story later on today.  As you read this BBC story, you'll see many links in it too.   Here are three I found especially worthwhile:

The story of how this was all put together and the path of discovery over the last years.  How it happened and why it is important:
http://www.bbc.com/news/science-environment-35524440

The five decades of teamwork that went into this astounding discovery and advance in astronomy:
http://www.bbc.com/news/science-environment-35541010

What are gravitational waves and what technology enabled us to discover them.  Albert Einstein predicted we would find waves which compressed and stretched the fabric of space/time over 100 year ago with his theory of general relativity.   As soon as the Advanced Ligo Experiment was turned on and able to detect these waves, they observed them immediately:
http://www.bbc.com/news/science-environment-35523676

There will be news reports about this all through the day in all major news and media reporting services.   I'LL ADD NEW LINKS BELOW HERE BEGINNING TONIGHT AND FOR THE NEXT COUPLE OF DAYS: 

ARTICLES AND REPORTS FOR ADDITIONAL UNDERSTANDING AND BACKGROUND:

Incredible energies were released in the merger of these two black holes.  The energy release that generated these gravitational waves spanning the entire universe were at a level which has never been seen before.   There is an excellent description of the Advanced Ligo Project and incredible extent and depth of the international cooperation here in a news release today from the LIGO. (Laser Interferometer Gravitational Wave Observatory):
https://www.ligo.caltech.edu/news/ligo20160211   Here's a quote that was  earth shaking to me.  

 "Based on the observed signals, LIGO scientists estimate that the black holes for this event were about 29 and 36 times the mass of the sun, and the event took place 1.3 billion years ago. About 3 times the mass of the sun was converted into gravitational waves in a fraction of a second—with a peak power output about 50 times that of the whole visible universe."

The waves were detected as soon as the much more sensitive Advanced LIGO Observatory started its first observational run last September.  This article from ARS Technica today explains many more important details about how this new kind of observatory and indicates how easy it was to see the signal once our technology was advanced enough.  It's measuring how the fabric of space time expands and contracts.  The waves penetrate and object in the universe without the least difficulty, even entire galaxies and incredibly dense objects like neutron stars and pulsars.

For the first time, scientists have detected tiny, rhythmic distortions in space and time - gravitational waves - predicted by Einstein 100 years ago.

Star formation environments can be roughly grouped into three types, categorized by the density of their gas (or more precisely, the projected "surface" density of the gas, which is easier to determine than the conventional volume density). In moderately high density regions, where the gas is primarily molecular in form rather than atomic, there is a strong correlation between the amount of star formation taking place and the density. This result...

Temperature Check

Let's go around the world and see what the temperature outside is right now where you live (or are visiting). In NW Ohio (USA), it's 5 degrees F at 00:30 (-15 degrees C).

1. Where are you? City and Country
2. What is the temperature outside right now (F or C)
3. What time is it (using the 24 hour clock)

Let's see how far we can spread this around the globe!
