No laser communications system at Tabby’s Star
If alien megastructures exist at Tabby’s Star, new research has precluded the likelihood that those aliens are using lasers for communications within those gigantic structures.
[The scientists checked] for laser signatures, on the not unreasonable grounds that any structure large enough to encase a star – Boyajian [Tabby’s Star] is almost one-and-a-half times the mass of the sun – would have an internal communication system, for which lasers would represent a good candidate medium.
In the latest research, Lipman and colleagues decided to test the idea. They analysed 177 high-resolution spectra from the star, gathered by the Lick Observatory’s Automated Planet Finder telescope as part of the Breakthrough Listen Project. They estimated that the data was so detailed that lasers with power greater than 24 megawatts should show up. To hunt for them, the researchers developed an algorithm to perform a pixel-by-pixel analysis of each spectrum in order to identify “spatially unresolved emission lines that meet the criteria for an artificial laser signal”.
The good news is that they found several. The bad news is that a secondary multi-step analysis designed to pick up false positives discounted them all. “The top candidates from the analysis can all be explained as either cosmic ray hits, stellar emission lines or atmospheric air glow emission lines,” they conclude.
We must remember that alien megastructures are the most unlikely explanation for the random light fluctuations of Tabby’s Star. This research helps to strengthen that conclusion.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Everyone knows Alien megastructures don’t use stone age type communications like lasers…this research is obviously a government cover-up trying to keep us rabble in the dark about what is really going on.
Why use lasers when you can use instantaneous quantum entanglement? ?

Good stuff!
It’s ridiculous how much bizzaro-attention is paid to this. It’s hardly the strangest object on the list.
Maybe it’s just dark-matter….
Brendan–
>”They” are transmitting on sub-space frequencies.
We will have to generate an inverse tachyon-pulse by routing the main power through the plasma conduits. It’s never been done before, the phase variance is tricky, and we only have 8 minutes to wrap this up, but it just-might-work…..

wayne-
I’m giving all eve git capin’!
Its obviously still under construction so the only communications are going to be among the union work crews.
And its more than likely a government job.
So everyone is on a coffee break watching the one new guy actually work.
