On November 15th, five months after the spacetime ripples jiggled LIGO’s instruments, astronomers announced the detection of their sixth gravitational-wave discovery, which is the fifth from the merger of two black holes. The event, GW170608, came from the union of the smallest black holes scientists have yet “seen” using this technique.
The waves hit LIGO at 02:01:16 Universal Time on June 8th, during the project’s second observing run (November 30th to August 25th). Their passage triggered the alarm at the site in Livingston, Louisiana, but the detector in Hanford, Washington, was under routine maintenance and had its alert system turned off. Even with the ongoing tinkering, the Hanford interferometer detected GW170608, too.

There are two kind of countries: Those that use the metric system, and those that have detected gravity waves.
You neglect Italy.
They stopped using the metric system?
Then there are those that use gravity waves ...
And what in the hell is dark energy & dark matter?
(Aside from magic that makes calculations work)
The interstellar big Kahunas surf gravity waves at GW170608.
Meter kicks is mostly what they “see”. Then they make up a pretty graphic. Grant writers, being stupid, buy it.

A little off topic. Dark matter and dark energy are stuff that make observations consistent with calculations. Science is driven by observations. As early at the 1933 Swiss-American Astronomer Fritz Zwicky noticed that gravitational attraction between luminous material could not explain galactic clusters. Centrifugal force should tear them apart, but they did not seem to be coming apart. He coined the term "Dark Matter". Dark matter need not be mysterious. A lump of coal will do. Just a lot of them.
Other explanations exist, but most alternate hypothesis have been shot down by detailed observations and analysis. Dark matter, as currently most widely understood, is matter that does not interact with light - electromagnetic radiation - but does interact with gravity. (Except to the extend that photons interact with gravity.) Neutrons would be an example. There appears to be little debate about the amount and distribution of dark matter, what is not know is its nature.
Dark energy is what drives the expansion of the universe. There is much observational evidence not only that the universe is expanding, but the expansion is accelerating. Quantum mechanics predicts a certain vacuum pressure for space, but its value is several score orders of magnitude greater than what is observed.
This is not theory patching or idle speculation. We do not have a coherent theory of everything, or even a satisfactory cosmology. But if we are to arrive there, we have to start somewhere. This is the best we can do so far.
No, the observations are consistent between (and counting Virgo, among) sites, and consistent with what is known about the universe and general relativity. This is first rate science, and cutting edge. No one pretends to have all the answers, but hopefully, we are starting to ask the right questions.
It is very provocative that the one apparent neutron star collision observed was consistent with simultaneously observed ultraviolet light.

so that's what woke me up
They forgot to mention that the “smallest black hole” in existence is the one where Maxine Waters claimed she had a brain.
“Black hole” is racist.
The term should be...
Massive gravity spot.
Blacks will be calling me tomorrow to thank me.
Today's real scientists recognize that the universe is electrical and that the Dark Matter is really plasma. In the same way that water vapor can be in the air but invisible but with matter there are the 4 states:solid, liquid, gaseous & plasma.
Thus the old school guys have to invent crazy motions such as Neutron stars since gravity is the only tool in their box but it's best explained in the electricity toolkit. Search on Electric Universe.
Yeah, I thought the same thing too. But I’m still averse to the old newtonian school of thought though. Though it beggars the question “what collided with what?”
There is a amazing thing called a magnetar which has a magnetic field so strong it has been estimated the energy density of the field is 10000 times the energy that lead would release if it was turned into pure energy.
Same thing!
