Star was dimmed by 90 percent. The scientist said whatever blocked the light had a hard edge.

It may not be a Dyson Sphere but some sort of debris or dust cloud.

Soooo cool when AI is used to decipher Stars and structure, black and grey colors are overwhelming.

And as always speculation, with no concrete evidence. Oh how I wish for the truth to come out with definitive answers.

The irregularity and scale of Tabby's Star's dimming challenge our existing models, indicating that there might be unknown stellar processes or complex circumstellar dynamics at play. Given these observations, could we be witnessing a previously unrecognized stellar phenomenon, or is the dimming still most likely attributable to factors such as circumstellar dust or cometary activity?

Just think how mich we could advance if wars stopped and we put all our efforts into science than killing

Why not just study the alien mega structure closest to Earth, the moon ?

This is surprising, have we started to come out of the box ?

Well, I guess that explains our moon.

I would love to believe this, but wouldn't a planet going around the sun like our planet does block it out also?

Somewhere beyond the edge of the galaxy we live in, there are always a few super spacecraft present.
Super spacecraft are 3.4 times the size of the solar system. They release spacecraft the size of the Earth into the galaxy we live in.
Those spaceships are of course invisible to us humans. We only accidentally see them when they are in visible mode.
Perhaps new super spacecraft are capable of destroying the galaxy and creating an empty space area 300 million light years wide.😊

Maybe we should only focus on what's happening around us on the globe right now 😢😢😢

Maybe it’s just the behavior of that particular star because of some unknown phenomenon that happens there. Automatically supporting the idea that an alien structure is responsible for that behavior seems bonkers to me

Wow, these people's imaginations are so amazing! They keep making things up as they go along. I wonder what they will come up with next? 😂

If they are Looking for something like this? I'm sure that if I was going to Look for something like this? Wouldn't that tell Us that They have Some kind of evidence that They have proof of (LIFE) ?? I think that They Do ! Thanks for your Time and video! JimS

Er no, it's it's simply a change in the plasma body of the object, as its electrical input from it's electrical filament stream changes. ET knows and uses plasma physics to get around and not warped woo woo maths guesswork.
