I like the new intro; it's very 1990s science show on public TV! I always marvel at humans assuming that alien life forms way advanced from our conception would build things according to our ideas. I like these ideas as theories applicable for human understanding of the cosmos, or our use eventually, but trying to extrapolate that to ETs is not prudent, IMO. Thanks for explaining this complex phenomenon. As with UFOs almost always being a weather balloon, there's probably a more usual explanation for irregularities thought to be Dyson spheres. Thanks for posting!
I think a dyson sphere is a stupid idea actually - and before any civilisation would be able to build one, they would probably have already found something better.
The idea that a planet would somehow be able to build a structure around a sun when there is not enough physical matter on a planet to achieve this. If you took the entire mass of the earth it would not wrap around the sun even one time, it would take the destruction of hundreds of planets to create one of these rings.
I originally had a small section in this video about the amount of material required to build a full Dyson sphere and some calculations, but I ended up cutting it out! Here is a summary: Obviously the amount of material required depends on the distance from the star you build the Dyson sphere at and how thick you make it. Supposing you build it at the orbit of Mercury and make it 1 cm thick (3.51818E+20 m^3), you'd have enough material on Earth to build it 3 times (or just 3 cm thick). But let's say you used up all of Mercury to make a Dyson swarm at the orbit of Mercury with 1 cm structures, you could cover 1/5th of the surface area of a sphere there with structures, which would still give you a noticeable light dimming and infrared effect.
If we use our current knowledge and beleives then we will think advanced civilizations would have advanced enought to build dyson spheres! But, we are thinking based on our current conditions! Maybe dyson spheres are really not nessesary once a cicilization is advanced enought!
the idea of a dyson sphere is ridiculous. why try to harness the power of a star once you have learned how the universe works to pull any resource or create any resource at will. entire galaxies if one wanted. Man was born to love Though often he has sought, like Icarus To fly too high And far too lonely than he ought To kiss the sun of east and west And hold the world at his behest To hold the terrible power to whom only gods are blessed But me, I am just a man
Just came from tiktok, dude your work is sick! Never give up I do hope you get a large audience
Thank you so much!
Let us know what you thought of the video, particularly the brand new intro/outro!

Thank you, I'm glad you liked it! Indeed, but 'it might be aliens' is just too good of a headline!
Love the new intro!!!! Your vids rock
And the outro!!!
Thank you!! Glad you like them :)

Holy Moley this is so rare I feel the overwhelming need to thank you for not being AI!!! (I hope) Great video too!
Beep boop, thank you!
I have one in my closet. They're pretty expensive but they work alright.
Harnessing the power of the sun to clean my living room!

That's definitely possible! The future is very hard to predict in 50 years, let alone 1 million.

Man was born to love
Though often he has sought, like Icarus
To fly too high
And far too lonely than he ought
To kiss the sun of east and west
And hold the world at his behest
To hold the terrible power to whom only gods are blessed
But me, I am just a man
