Black Hole Spews Out Material Years After Shredding Star


Astronomers observe black hole "burping" up stellar remains years after star was consumed. "We've never seen anything like this before."

Must confess that using terms like "burping" and comparing black holes to "messy eaters" doesn't give me the highest confidence on the science involved here.

Flotsam and Jetsam

Miscellaneous thoughts and observations.

Surprised the nickname "Canadian Beto" never stuck for Canadian Prime Minister Justin Trudeau... Perfume ads don't make any logical sense because they are not aimed at the smartest people... Winston Churchill had a habit of not reading any memo longer than a page. The result was nobody ever gave him a memo longer than a single page - genus!... Speaking of real men of genius... The Wages of Sin (Minus Taxes) would be a good name for a band... So if spaghetti approached the event horizon of a black hole - would it too become "spaghettified?" Or would it turn into another form of pasta?... If a monogamy gene could be isolated in humans - could future prenup agreements require that the gene be activated prior to marriage through CRISPR or some other method?...

Flotsam and Jetsam

Miscellaneous thoughts and observations.

Perfect storm coming for some campuses - most colleges are facing massive budget cuts due to the Wuhan virus meanwhile students (who don't know any better) are enamored with the talking-point of "defund the police." Boom - bye bye campus police departments (I predict you'll see at least one college go this route)... Elon Musk calls for the breakup of Amazon. "Monopolies are wrong!" As an aside Jeff Bezos also happens to be Musk's biggest competition when it comes to privatized space travel... "How soon before the word "landlord" is attacked and becomes verboten language? I mean by definition a "lord" is male (death to the patriarchy)... So Conor McGregor has announced his retirement from fighting (again). I'll believe this is true in about 5-years... "Times have not become more violent. They have just become more televised." - Marilyn Manson... So if spaghetti approached the event horizon of a black hole - would it too become "spaghettified?" Or would it turn into another form of pasta?...

Stephen Hawking's Big Ideas



Nice little appreciation of Hawking (I think it's narrated by Neil Gaiman).

Black Holes

This week the Event Horizon Telescope was able, for the first time, to show the world an actual image of a black hole. The black hole is located at the center of the galaxy Messier 87 which is 55 million light years from Earth. The supermassive black hole photographed has 6.5 billion times more mass than our Sun.

This was an excellent article on what this historic photograph really means and puts into perspective the difficulty involved in the accomplishment.

This article give you an appreciation of the epic scale of the black hole in relation to our own solar system.

Truly a monumental accomplishment and historic day.

As an aside, it think it would have been much more poetical and cooler if science had settled on the term "dark abyss" instead of "black hole".

The Second Law of Thermodynamics and Housekeeping

I'm in the process of reading The Theory of Everything: The Origin and Fate of the Universe by Stephen Hawking. When speaking of the behavior of black holes - Hawking talks about the Second Law of Thermodynamics:
It states that the entropy of an isolated system never decreases with time. Moreover, when two systems are joined together, the entropy of the combined system is greater than the sum of individual systems.
My initial thought was of a post earlier this week at Instapundit which had the line:
Both the men and the women who got married did more housework than those who stayed single, the analysis showed.
Both black holes and newlyweds acting in the same manner? I guess when Stephen Hawking said it was "the Theory of Everything" - he wasn't kidding.

Of course I could be completely wrong here since my grasp of physics is as bad as my ability at house work.
