It's not the first time I've discussed Fast Radio Burst (FRBs): I had posts in 2013, 2015 and just last year in 2016. I first read this in Science Alert, then followed the links to arXiv. Although I've posted from physics arXiv before, some things I should give as a caveat emptor:

- The arXiv is a pre-print journal, i.e. it precedes publication in peer-reviewed, scientific journals.
- As such, it's a good way to "get an idea out there." The first stringent peer reviews should be from your own research team. You can also in subsequent submission to scholarly publications correct previous conclusions, especially after peer challenge.
- You can submit your paper here, if you're a registered author.

What took me aback was a Harvard astrophysicist* submitting it, and it's apparently not as the colloquial phrase goes, his first rodeo (see #P4TC related link below). I was a little thrilled and a little worried if the hypothesis falls flat.

However, it does work on physics that we know, or at least think we know: we haven't built a functional solar sail YET, but it's a little more practical on our humble 0.7 Kardashev Scale than warp drive (to the chagrin of my inner Trekkie), but within the realm of reasonable relativistic speeds, a fraction of light speed, but doable.

If we're receiving these fast radio bursts, the question are: is this just stellar phenomena, a lucky observation break, or are we in a flight path? And if the latter, for what purpose?

* Loeb admits that this work is speculative. When asked whether he really believes that any fast radio bursts are due to aliens, he replied, "Science isn't a matter of belief, it's a matter of evidence. Deciding what’s likely ahead of time limits the possibilities. It's worth putting ideas out there and letting the data be the judge.”

Abstract
We examine the possibility that Fast Radio Bursts (FRBs) originate from the activity of extragalactic civilizations. Our analysis shows that beams used for powering large light sails could yield parameters that are consistent with FRBs. The characteristic diameter of the beam emitter is estimated through a combination of energetic and engineering constraints, and both approaches intriguingly yield a similar result which is on the scale of a large rocky planet. Moreover, the optimal frequency for powering the light sail is shown to be similar to the detected FRB frequencies. These `coincidences' lend some credence to the possibility that FRBs might be artificial in origin. Other relevant quantities, such as the characteristic mass of the light sail, and the angular velocity of the beam, are also derived. By using the FRB occurrence rate, we infer upper bounds on the rate of FRBs from extragalactic civilizations in a typical galaxy. The possibility of detecting fainter signals is briefly discussed, and the wait time for an exceptionally bright FRB event in the Milky Way is estimated.

The Fifth Season is coming to TV!

N.K. Jemisin’s ‘The Fifth Season’ Book To Be Developed As TV Series At TNT!

Now Mr. Hayashi can't complain about there being no other famous black creatives than Delany and Butler. 

http://deadline.com/2017/08/nk-jemisin-the-fifth-season-book-developed-tv-series-tnt-1202150542/

Now who says diversity doesn't sell?! If some yesteryear agent says that, throw this article in their face and say "Are you sure? Now get me TNT's president and NO I won't hold!" 

Of course, this assumes TNT won't screw this up like they did the TFTC revival.

The Black Ring Society: Prologue: The Ways of Worlds

Posted by Nelo Maxwell on August 16, 2017 at 12:07pm 0 Comments

Every story has not two, but multiple sides to it. Some span lifetimes others generations and some very rare ones span realities. It all depends on how many dimensions you can see it in. This is one such story, a story of family, of secrets and the duty that goes along with it. This story has and is being played out on multiple planes of existence, sometimes one after the other, sometimes simultaneously. The details of the story and how it relates to itself among the various realities is complicated but needless to say this chapter of it, which will probably be a long one, should help to elaborate on the intricacies of the grander picture in both depth and scope. I’m am aware that in this reality there is a tendency to reject or block out things which the mind cannot comprehend, but I assure you that this is not only comprehensible but completely understandable. However that is only for the few who would understand this sort of thing. A myth wrapped in a legend packaged in a good bit… Continue

SKYCITY TALKRADIO

THE UNDERGROUND BY ROXANNE BLAND

Life as alpha of a werewolf pack is anything but predictable. But even Parker Berenson is surprised by the latest twist: he’s fallen in love with a space alien. Problem is, he suspects Melera, his sexy new flame, might be the serial killer terrorizing Seattle. Or maybe she isn’t. After all, just because she’s an interstellar assassin doesn’t mean she’s guilty.
