There are so many things we do not know that we don't even know what we don't know.

^but in this latest development something we knew that we didn't know we knew until we remembered. ; ).

Butter is good, margarine is bad. Hang on, butter is bad, margarine is good. Hang on, now butter is better than margarine.

I am suggesting everytime a scientist "discovers" something the internet dogmatises it until the next "discovery" when everything is refuted and till the next and so on.

Every so often there will be some new discovery that is entirely meaningless.

On a more serious note; a few days ago this lecture was posted

Btw latest is showing the long term dimming may be a measurement error. Ie; no long term construction project in progress.

The Kepler data indicating something transiting the star is still regarded as correct, and is still a scientific mystery.

This is cool. It is a much better investment than the next Whitley Striber : ).

A new theory (I am guessing it's a theory ...)

 

http://www.dailytelegraph.com.au/technology/science/kic-8462852-tabbys-star-may-be-a-star-suffering-indigestion-from-swallowing-a-planet/news-story/c2f4f935e9e711d96485dac53d76b9aa?from=htc_rss

 

 

Until we get more data, they are all theories.

 

The main thing is this:

 

All we have so far is crude light level dimming data. We need to wait for the next radical dimming episode and observe the spectrum of the star's emissions during that dimming episode. Then we will be able to judge those observations against the theories.

It's just a somebody's drawing.

 

You can do your own if it helps.

jpoc: There is another development here. A study of photographs of the star going back to the late nineteenth century indicates that, as seen from Earth, the star is steadily dimming at around 20% per hundred years. Stars like that do not do that by themselves. There are no current hypotheses for natural events that can be responsible. https://www.newscientist.com/article/dn28786-comets-cant-explain-weird-alien-megastructure-star-after-all/

I am debating theory vs hypothesis.

Whatever is doing it, it is at it again:

 

http://www.nzherald.co.nz/technology/news/article.cfm?c_id=5&objectid=11861251

 

The star entered a new dimming phase at the end of last week and the race is on to point some serious telescopes at it.

 

This is important because all we know up to now is that the star's luminosity dips but we have no measurements of how the light spectrum changes during those dips.

 

If we can get that information, we will be a lot closer to working out what is actually going on.
