Unusually long and repeating gamma-ray burst, 'unlike any other seen,' baffles astronomers

Boffins Baffled Between Bursts.................

Astronomers baffled.

Because they don’t watch Ancient Aliens.

Thanks but I’m already there.

I was brought up in the early 1950s when we learned to duck and cover under the elementary school desks.

Old reflex now for such news.

In the book “Contact”, not the movie, the space alien tells the lady astronomer those quasars and stuff are actually them experimenting in ways to stop the universe from collapsing in the distant future.............

Many scientists are “baffled” a lot.

That’s so they can ask for more money to study the thing that ‘baffles’ them.

Interesting.

I should have read that book. Didn’t. I saw the movie.

String theory.

Jasmine Crockett: “I often play with string. Tangle and untangle it. Keeps me interested and the hours just go by so fast.”

[Red Badger]

Forget the movie.

The only thing they used was the title.

The book was waaaay more interesting.

If you get a copy, you will swear off the movie for good..........

[frank ballenger]

Wow. Thanks for the tip. I have never gone wrong reading something suggested by FReepers.

[Red Badger]

When you read the book, you will say to yourself, “What the hell was Hollywood thinking?”.............

[frank ballenger]

Thanks.

This is an intergalactic spam call about our Planetary Repair Warranty. I don’t think we can afford this expense right now.

Epsilon 3 testing their weapon system?

"Astronomers have observed such jets firing erratically in events like Swift J1644+57, described in a paper that modeled how a powerful magnetic field around the black hole could drive on-off behavior."

Good grief!
It appears that we now need a "Black-Hole Control Law"...
There is no absolute need for black holes that explode/erupt so fast and rapidly, thereby causing danger to the public galaxy members...

A case can be made for single-eruption black holes, but semi-automatic or fully automatic are unsuitable in a civilized galaxy...

“Old reflex now for such news”.

I understand. Lol Born in 1951.

Explains outliers Jerry Nadler, JB Pritzker and Stacey Abrams.

Then all the rest of us.

In the library where is worked in the 1970s there was a story that three floors of books would protect the people under them from cosmic rays.

But later was said to be not good enough.

One segment:
An extremely thick, multi-story structure made of books would be necessary to offer any significant protection from gamma rays from space, making it an impractical solution. It is virtually impossible to provide complete protection, as highly energetic gamma rays are extremely penetrating.

Unlike concrete, books are made of paper, which is a low-density, low-atomic-number material, inefficient at absorbing gamma rays, allowing most of the radiation to pass through with minimal interaction.

Materials rich in hydrogen, like water and plastics (or, in this case, paper) are more effective at slowing down these neutrons, which can also be harmful. However, the primary cosmic rays themselves are so energetic that a thick shield of any material is needed. ...you need roughly 2.4 times the thickness of books as you would concrete of books.

A single floor is typically 10 to 12 feet high. So, protecting against “typical” gamma rays would require more than one full floor of books. However, gamma rays from space can have much higher energy levels, which would require significantly thicker shielding to stop effectively.
