    Eventually people will make one but i dot think there is enough material of anything in our planet so we would need to travel to different solar systems and planets to even mine or extract enough material. But if humanity learns how to get to different planets and solar system (before we kill each other or extinct ourselves) then ..... yea it’s not happening unless we find a duplication glitch

    ​@alertonoff 4 ..... but we are talking about this happening verry far in the future and with satalites that can be added over time gradually, true it seems crazy to do it now but so was building skyscrappers or going to space a thousand years ago would have also been insane and impossible to pay ....

    Full sized? Nope. That would require the world being able to work together under a unified, functioning leadership, which is, in my opinion, far less likely than accomplishing all of the mechanical challenges required to build the structure. That, and I don't think we have that much time. ;)

    I thought the Dyson Sphere was a solid structure, as opposed to the series of rings you displayed. Which honestly makes the moral dilemma of harvesting the entire system a moot point. Those planets would be shut off from the suns light anyway once the Sphere is finished. The idea of the brain though is terrifying.

    Instead of a solid sphere, why wouldn't we just build a satellites system encircled the sun on low orbit (the Dyson swarm) ? We would need far less materials (though probably still need to dismantle a planet), it will be immune to asteroids (since it is not solid, and in unfortunate cases a satellites get hit, we would only lose a single, replacable satellite instead of having to repair the entire thing), and far cheaper.

    I've always found it fun to think about sci fi always, ALWAYS having some sort of great precursor species that colonized all the stars and fell into ruin, leaving all the current different species on planets to advance themselves and rediscover the ancient one's technology. But, but what if we're that ancient precursor race in the making? What if we will be the first to expand massively across the stars, only to die out in some grand tagedy far, far into the future leaving our creations as their own species on their own planets? Who's to say we won't *actually* be the first? I mean there has to be a first. What if we're it?

    It would be impossible to make a dyson sphere because it would take more resources than a planet has and would require a resource that couldn't flex or sheer. It would probably need an impossible amount of heat to form it too.

    Why bother making the spehere sturdy. Make it flimsy. Let the asteroids punch through, and repair it. Would be cheaper than making the whole thing asteroid proof. Also, by the time we can make a dyson sphere, we would have mastered the ability to manipulate asteroids. We would have cleaned up most of them. Does the sphere need to be solid at all? Couldn't a magnetic shell accomplish the same thing? Hmmmm, I guess a magnetic shell would be a necessary stage in the process of creating the sphere. And thoughty, you never mentioned the required resources. Would we have process all the other matter in the system to make such a structure possible?

    Building a dyson sphere is like collecting every tree on earth into a pile then setting it on fire to fuel a giant boiler. Its a batshit crazy idea that would cost soo much more resources, to do the same thing fusion would do at millions upon millions of times less cost, for way more energy.

    Instead of a Dyson Sphere, why not a Dyson Disc or Dyson Ring? Instead of fully encompassing the star it would be more like a ring, still absorbing a ton of energy. Also another issue with Dyson Spheres is that they will collapse under their stars gravity. A ring around a star that is spinning would act like a really stretched out planet revolving around its star. The spinning motion creates an outward force that counters the star’s gravity and would technically cause the Dyson Ring to be in orbit. As for the Dyson Swarm, we still have a problem, the satellites nearest the star’s poles in orbit would fall out of orbit and into the star (the equator being the ring that is revolving at the speed to keep it in orbit- all other points would be moving slower and thus slowly drift into the star. Any ring moving faster would start moving away from the star..). Each ring of satellites would need to be orbiting in their own direction which would suggest many different layers to prevent different rings from colliding with each other.

    At 20:00 you talk about how the sun isn't being blocked by a single megastructure, rather lots of very small objects, therefore it's unlikely this is evidence of life. You then go on to talk about how Dyson Spheres as you commonly think of them are impractical, and if we were actually going to do that we'd likely just slowly flood the suns orbit with lots of smaller solar satellites. Did you not think to combine these lines of thought? Maybe ET have some kind of micro satellite technology and they can just release swarms of these things to create quick and easy power generation.
