Re: The periodic and secular dimming of KIC 8462852 is not due to comets
I am in the middle of writing a paper regarding my thesis.

I also have a sense of humour but also hold you as a peer so to speak.

Very few people would even begin to understand the dynamics.

Kick starting a core would require a lot of energy, more than likely at some point some explosions will have taken place at the core as well as potentially drilling to the corebof the planet, similar to sinkholes? That or after mapping a huge volcanic system on the planet energy could be directed into the core.

At some point the energy being redirected will have to be lessened, but not stopped as the potential planet being terraformed would be too far away like Mars to remain under the constant influence of the stars energy.

Forgive me, I wasn't trying to dismiss your idea, like I said I find it interesting and unique. Obviously it would require a lot of number crunching to see if it's plausible or not.

Well to me that would seem to be overkill but maybe not. Scott Manley actually has a pretty good video on YouTube showcasing how much energy it would take to destroy a planet in a Death Star like fashion. Perhaps this is Starkiller base getting ready to destroy the rebellion or something lol.

Re: The periodic and secular dimming of KIC 8462852 is not due to comets
It has a small black hole or another very dim star in orbit around it that is stealing its gas, thus the long term dimming.

Seems an obvious theory. First detection of small black hole?

That's where I was hoping you would come in.

Crunching those numbers and extending my theory.

I'd like to have an open discussion were people are able to construct the idea based on our system and our technology and seeing if it applies to tabby.

I don't know many people on here but I'm sure there are engineers and physicist's around and hopefully some geologists who could provide information on whether the theory is plausible.

Thank you though

For entertaining my thoughtd

Re: The periodic and secular dimming of KIC 8462852 is not due to comets
Some random thoughts...

Isn't SETI looking for radio signals from this a bit of a wast of time? I would imagine any civilization advanced enough to create a megastructure would have long since moved on from using radio signals. And since they are only 1400 light years away what ever period of their development they may have used radio signals would have long since "washed over" earth.

It seems fair to say the steady decline in brightness points to "growth" or increase in what is obscuring it? So obviously that would make one jump to the conclusion of construction of the structure...

If an alien race has the tech to build a "death star" then i don't think they will need it to destroy our world. Their tech would be 1000's of years beyond us. And we wouldn"t be able to stand against them.

I thought the latest theory was an oblate star...
 Quoting: idoubtthereforeiam


That was one theory, but I don't see how that explains this steady secular dimming.
 Quoting: Dr. Astro


Could there be a natural phenomenon that acts the way a "Starkiller Base" would? Like a moving black hole that "orbits" the star, slowly pulling matter away from it and also occasionally passing between us and the star, absorbing radiation that would otherwise head towards us and creating the unusual dimming effect?

Fair enough. Regardless, I'd say 99% chance its an unexplained/unexplored natural phenomenon, 1% chance aliens. But I'm rooting for the 1%.

A black hole drawing matter away from the main star would be quite noticeable. The matter would form an accretion disc around the black hole, heating up massively as it falls inward.

Re: The periodic and secular dimming of KIC 8462852 is not due to comets
How about we dont understand stars, and iy isnt an object or aliens but rather an effect of the star itself dimming.

I know this is not how stars opperate on this short term, however, there are many observations of our own star that do not meet the model of burning fuel.

Could this be explained if the star was shorting out like a light bulb dims from a surge or something. What i am sugggesting is that the simplest explanation is that we severly understand how stars or stars like this oppperate.

It is easier to believe then an alien civilization building something to harness the solar power of a star, thats seems so wrong. When they would be so far advanced that energy is derived from other more efficient means.

If comets are now ruled out, what is the next plausible natural explanation?

Also, has any gravitational wobble been detected to suggest the presence of a nearby massive body?

They are all Alien to me.

But, it did make me think, where oh, where are they going to get money to do anything.

Also, how did the asteroid belt look at night? I think something like stars twinkling in the night sky.

As they reported years ago, they got signals they thought were alien, it was I love lucy, and a lot of other like the three stooges. Bouncing off the sphere above the earth.

Hey Astro couldn't a small black hole be weak enough and perhaps far enough away to very slowly draw in the stars qas without having a easily seen accretion disk?

How small can a black hole get without vaporizing right away? I understand vaporizing is probably not the right word.
