Have We Really Detected Dyson Spheres? The Real Story

This month, two teams of astronomers announced the potential discovery of Dyson spheres in our galaxy. But have we truly found indicators of highly advanced civilizations? Join Dr. Franck Marchis and Dr. Lauren Sgro as they delve into these groundbreaking findings and their implications for SETI research.

But, but, but, can you create a technology to raise the standard UFO photo quality above 18 dpi?

[krishnachivukula]

I find it incredible, that we can generate some reasonable observations which could indicate the presence of intelligent life…it may not be there, but the mere possibility fills me with awe

this is a good length and format for this type of information!!!

[steverafferty]

You should do much more videos like this. Well done.

the problem i have with dyson spheres is that a civilization that can build such a massive structure already probably knows how to produce fusion energy.. it would be much more efficient to build many small fusion reactors than envelope a star with some primitive "solar cells" for photons when you can go straight to the source of the power.

I don’t know how thin the solar panels can be constructed. But let’s say it would be possible to construct, I’d really try to make it as natural appearing as possible, if I was the alien civilization

great video, great discussion, great paper references, keep it up!

[ArthurPerron]

Good job SETI! I will be doing an episode on this on my podcast, "Universe-ity" on Spotify and Apple Podcasts later this week. Thanks for all your great thoughts!

If they have built dyson sphere in space will it not effect gravity between sun and alien species planet .
Let the mass of sun
Let The mass of Dyson
Add both kg with this will not effect their own planet questions need to asked.

The real explanation will probably turn out to be dust. There was a lot of hype like this about Tabby's star several years ago. Surely a Dyson sphere would need enormous amounts of refined material (metals, semiconductors, glass).

[princeplanet]

Well presented and interesting discussion. However I would need to be certain every potential natural explanation had been investigated and conclusively discounted before entertaining possible ETI causes.

[KentTreber-jmut]

We understand the composition of the Sun, which includes metals like iron and magnesium among other elements. By following the recipe and adding these to a containment area, then igniting it, we wouldn't need an entire star—just a new mixture. These stars could be smaller and easier to manage with less heat. We have now inherited four Dysons and one central facility, Yorktown. Brace yourselves, SETI; you're in for a wild ride.

Let me just elaborate Dyson sphere means we are watching type 2 civilisation harvesting its energy from its own Sun ☀️
Type1 civilisation: where we can use full energy from earth resources for our energy utilisation and for our needs

Type 2 civilization:means Dyson sphere structure for energy harvesting

Type 3 civilisation : means we can use Galaxy stars . Even black hole etc.
Above there are type 4 type 5 type 6 are been classified depend upon energy utilisation of any civilisation.

[gustavderkits]

Lasers and masers do occur in nature, in planetary and circumstellar astronomy, but are rare and usually easily explained by the context.

[nealdaniel]

I never understood why a Dyson sphere would be necessary when panels in space can collect more than enough energy for our needs (think ISS). Shouldn't we be looking for unusually dim planets instead?

[MD-vmyy]

The real question here is, who's behind those two black crates on the right?

[zapfanzapfan]

Quick, go there and rescue Scotty from the transporter buffer! 🖖

[paulhemmerling]

I was really excited about this news until Dr. Sgro mentioned the Kuiper Belt stuff... That is a much better explanation than a Dyson Sphere.

[barbholt]

These Dyson's would as the person they are named after also thought, would most probably be spherical as to envelope the whole orbit of the host star.

[igorgotmail]

I am convinced that if a civilization has the knowledge and the knowhow to build a dyson sphere, that nuclear fusion has no secrets to them anymore. So that they can build their own infinite power sources on their planet or on a satellite powerplant circling their planet without the need of building an extreme megalomaniac project like a dyson sphere around a star.
