Tabby’s Star: More weirdness

Remember Tabby’s Star? It’s the star that astronomer Tabetha Boyajian – who reported its strangeness in a Ted Talk in February, 2016 – famously called “the most mysterious star in the galaxy.” It’s mysterious because astronomers have never seen another star do what this star does. One explanation for the strange dimming of its light is that the star has an alien-built megastructure – a Dyson sphere – around it. Does it? Will we ever know for sure? Those are unanswered questions, but, while you’re pondering it, here’s the latest on this wonderful star.

On August 3, 2016, two astronomers added more evidence that Tabby’s Star – also known as KIC 8462852 – is just plain strange. Benjamin Montet with the California Institute of Technology and Joshua Simon with Observatories of the Carnegie Institution of Washington have uploaded their paper to the arXiv preprint server detailing their study of the star by analyzing data from the NASA’s Kepler space telescope (a famed planet-finding telescope) over the past four years.

They found that the star has been decreasing in brightness at an unprecedented rate.

There are two reasons a civilization would create a Dyson Sphere: to collect energy to supply the civilization and to hide from other menacing civilizations.

The existence of Dyson Spheres could mean that this civilization knows there are baddies out there that can come get them and want to hide.

If there were a culture able to build a structure around a star 1500 years ago, imagine how advanced they’d be by now.

...or they could have died out yesterday on the eve of their first exploratory mission to Sol's third planet.

Not sure a Dyson sphere is a good way to hide. The change to the star’s signature might be a dead giveaway. After all, it attracted our notice.
And there would be no reason to collect the energy if the civilization has access to the stars. If it is a Dyson Sphere, then it likely means that they can’t escape their system in any efficient fashion, so they are maximizing on the resources they have.

“A Dyson Sphere in the making?”

Lawyers from the EPA are preparing their lawsuits to stop construction until a comprehensive EIR can be drafted and submitted for proper review.

Because of the time it takes to create, and because any advanced menacing civilization will have mapped out all of the stars in their neighborhood, I agree with you that it wouldn't work that well as a hole to hide in.

However, that's one of the reasons Dyson mentioned, and it is a major plot point of some sci-fi novels.

There are even people trying to figure out ways of detecting completed Dyson Spheres by use of principles such as black body radiation from the exterior of the sphere, etc.

The answer could be as simple as looking at what happens at this star:

Epsilon Aurigae has baffled astronomers for years, until this last cycle when we could see the cloud.

The heavens are full of mysteries.

“There are no aliens! Anywhere! Period! Geez...”

There are over 200 billion suns in our galaxy, most of which are proving to have planets, and our galaxy is just one of countless billions of others.

It’s not even possible for most humans to wrap their minds around the vastness of our galaxy, let alone, the entire universe.

Simple logic dictates that the universe is teeming with life. We just have to grow up enough to find it.

What if your Dyson Sphere causes your heliosphere to collapse?

The troubles with the unions alone could cause the whole mess to drag on for a thousand years.

Hah!! Unions would be the least of their worries -- Just imagine the Environmental Impact Report filing that would be required. :=)

“Uhhhhh...but no...”

Logic is not on your side here. The fact is, there are more suns in the universe than all the grains of sand on Earth, and most of them have planets. The number of potential planets is incalculable.

For life to have formed on only one little rock, in all the unimaginable vastness of the cosmos, is simply ludicrous. In time we’re going to find that it’s out there, and that it’s everywhere.
