Once Around Tabbys Star

A look at the mysterious discovery of Tabby's star and the range of possible, and bizzare explanations!

Your videos are pure gold. Thank you so much!

Thank you Mr. Fellows for your entertaining and educational videos.

Thank you, Mr. Fellows, yet again! I've also heard that Tabby's Star is near or embedded within part of the nebulosities of Cygnus (which has plenty of them). Enough dust and gas between us and it, and it's going to cause partial, selective and irregular variability as it moves through it, and the dust moves past it, like a headlight dimming through fog.

I'm holding out for the Dyson sphere! We look for what we understand - radio, laser, light emissions etc. However a species able to build a Dyson sphere are conceivably using technology we can't even imagine. I find that fascinating. Great video, really enjoyed it!

I like to save these videos for the end of the day, but it is getting harder and harder to wait. I get so excited when I see a new one in my feed!

Over the years, I've kind of settled upon the conclusion that these effects are the result of a tidal disruption event, but that's a guess. My hope is that Vera Rubin finds many more anomalous objects akin to this one

Last time I was this early, baryogenesis hadn't occurred yet.

Another great talk thank you Paul. Unfortunately they keep me awake at night listening to them when I should be sleeping! You have a great gift, and I hope you create many more.

[Chris.Davies]

Yeah, nice. Except for one thing. This would break the Dyson Sphere Rule.
And that rule very clearly states: IF YOU CAN BUILD A DYSON SPHERE/SWARM, YOU DON'T NEED A DYSON SPHERE/SWARM.
The idea that super advanced alien races rely on solar power is absolutely laughable.

I wonder if any of the Voyager or Pioneer probes were ever used to look back on the sun to measure light curves of the planets passing in front of our sun, as perhaps a check or calibration tool on our measurements of light curves elsewhere?

It took 4.3 billion years before intelligent life appeared on Earth. An F-Type star doesn't have that long.

So could a small starforming dust ( nebula but very small) cloud move into that star system and then get teared apart, maybe the amount of dust could make a brown dwarf or someting smaller

A Dyson sphere is not particularly a great energy project. Indeed the resources needed would be immense and the payout not that great since a star is not efficient in term of conversion of mass in usable energy, around 1% . They would rather produce antimatter as a fuel which would then have 100% conversion into usable energy.

[RaymondSwanson-uy]

How about two brown dwarfs in a three body complex with the star? The three orbiting each other.

The Dyson Sphere is the most hilariously ridiculous concept in the history of science. Some guy thinks of something & automatically it becomes possible. It reminds me of how, before The Matrix, there weren't any "We live a simulation" theories, now they're everywhere 🙄
There isn't a single Dyson sphere in the entire universe. Never was, and never will be.
