    One potential use for a Dyson Sphere might be to open up a wormhole. If exotic matter does not exist, then it might very well take the entire energy of a star to open up a wormhole.

    If we are visited by aliens it is only natural that they would want to communicate with only the rich and powerful since they would be the only humans on their intelligence level. Megan McCain, the Kardashians, Billy Eilish, The Clinton's & other luminaries would be our best candidates to represent humanity. Scientists would be the worst choice since they don't have the intellectual capability the first group mentioned possesses.

    Dyson spheres don’t make sense. Even if you assume the engineering were feasible by an advanced civilization, there’s no reason they would need that much energy. And if they have enough energy to construct a Dyson sphere, they would already have enough energy for all their needs. 🤔

    I think that you guys have something wrong in you calculations wrong about how stars undergo fusion and specifically what gets fused at which stage they are fused and in what amounts and how the star deals with the heavier elements that begin to accumulate inside it. The idea that heavier elements are only created in the final moments of a dying massive star is outdated and not what we are observing. Stars the size of the sun have been shown to periodically have a nova event where these heavier elements rise to the surface of the star and get ejected out. Eventually forming the debris disc that coalesces into the stars planets. Our own star Most likely formed with Jupiter and possibly Saturn but the rest of the planets get created by the star over billions of years. This process happens faster the larger the star is. We know that Supernova only take place in a few specific cases with the star having the correct size and composition. It is actually as likely or more likely that our sun formed shortly after the galaxy from virgin materials instead of being formed from the remains of a massive star that lived a very short life before going super nova. It could actually be true that our solar system formed from a combination of both things. A scenario inn which our sun was near a massive star that went supernova and survived the explosion. Picking up some of the debris that coalesced into the gas giants This is a terrifying scenario for scientists to admit to because it means that periodically the sun will do something that sterilizes almost all life off the planet. Something we actually know has happened many many times. We just never attributed it to the sun. We observe dozens of stars close to us that actually do this with very frequent regularity. Some having done in many times in the century or so since we discovered these nova happening. We aren't even sure what the Earth encounters on it's very long orbit around the Milky Way. We could come very close to black holes which cause time to dilate. We could get exposed to all sorts of radiation and magnetic fields. We could even be subjected to static electric discharges generated by the black hole at the center of the galaxy which would essentially by lightning bolts that instead of being millimeters wide are 5-10 meters wide. We wouldn't even be able to see them traveling across the galaxy in a vacuum at the speed of light until the strike and create something similar to our largest nuclear weapons. If our planet is a giant magnet. The sun is a giant magnet and the black hole is a giant magnet. The effects of one on another would trickle down hill. The biggest mistake I think we can make here is to assume that we have everything figured all the way out. Too much of what we think is based off assumptions made nearly a century ago that nobody has ever stopped to question. We assume the speed of light, we even assume it is a universal constant. But we have no way to actually measure either of those things, despite what they might tell you. The machines they use to measure these things were themselves calibrated by a man, based off assumptions about these things. Those men couldn't begin to observe light traveling as anything other than instantaneously. From the lights perspective time stops so it does happen instantly. You would need an experiment larger than the solar system to detect if lights speed is constant, something we can not achieve with our current technology. But I'd be willing to bet that light increases it's speed exponentially as it red shifts over vast distances. As a coiled spring does when it decompresses. That is what the shifting is, energy being converted into velocity. Do you know what this theory solves? Every problem with physics, and astronomy. I don't know why it doesn't seem obvious to anyone else. Making up dark energy and the universe being expanding at an exponentially increasing rate in order to explain away what is actually light accelerating. Photons have no mass, there is nothing in the laws of physics that says they can't go faster, they are the thing that dictates the universal speed limit. Just like anything else fast, getting that last little bit of speed out of it at the top end takes a minute. We actually have no idea how fast light could possibly go, it could continue to accelerate indefinitely. There is no way to prove this right now, but you can observe it happening all across the sky. When you realize that all the silly things we've come up with as an explanation for these phenomenon are caused by something so obviously simple it makes you wonder what else are we getting wrong?

    That's too much work to build. Ps isnt sun too hot? If you go out to earth size orbit aside from not having magnetosphere the surface area of dyson sphere would be 27,200,000,000,000,000 miles. Do you know how much material and energy it would take to produce that. And that is with essentially no thickness. Imagine maintenance alone from damage. Aliens sure. Dyson sphere just not feasible. You're better off learning how to make other planets habitable

  • @Nichejackers

    The Dyson sphere has to be the most ridiculous theory about advanced civilizations getting their energy I've ever heard. It was created to substantiate another theory called the Kardashev scale. Collecting energy from their star would be a type 2. It's totally not practical. There just isn't enough solid material in a solar system to create a structure that big. It's completely science fiction.

  • @JohnMichaelGodier
    @JohnMichaelGodierКүн бұрын

    Kardashev is a classification scale, not a theory. One can easily substantiate whether a proposed classification system exists or does not. And we covered what is meant by a Dyson sphere in the video, including caveating that it does not necessary mean a solid sphere. Thirdly, there is well enough solid material in some star systems. Dyson did the calculations and it's one Jupiter mass for a three meter thick sphere at 1 au in radius in principle. We don't quite have it, we'd need cheap transmutation technology to get to carbon for layering graphene to do it with Jupiter but it's a complete misconception that there isn't enough material in a star system that Dyson shot down in his first paper proposing the idea in 1960.

  • @JohnMichaelGodier
    @JohnMichaelGodierКүн бұрын

    And also, Dyson's paper came out four years before Kardashev's scale paper. The idea itself is actually even older, going back to the 1930's and Olaf Stapledon's novel "Starmaker". It was not created to substantiate the Kardashev scale.

  • @JohnMichaelGodier
    @JohnMichaelGodierКүн бұрын

    @@Nichejackers Oh he shot it down. He posted the calculation. Dyson also did not actually envision a sphere, nor did he call it that. That was Nikolai Kardashev, and that is a theory. Dyson's description was intentionally vague as to not pidgeonhole the idea as a single structure and he also didn't limit it solely to energy collection, and he also did not believe that an encasing shell was mechanically possible, which it isn't with current materials. And where we invested the money was in building a Dyson swarm. All of the active and defunct spacecraft we have in solar orbit is technically a solar Dyson swarm, if a tiny one. It will only grow the more we launch and those satellites will be out there after they're dead for a billion or more years. An example of one around a planet is starlink, which has over 5000 identical satellites up now cover almost all of the surface of the earth.

    Dyson spheres are unlikely. Any civilisation with the technology to build such a construct would be quite capable producing all the energy they need from fusion reactors. It's difficult to imagine a civilisation that can build a Dyson Sphere but that cannot produce sufficient fusion energy to match it. Dyson Sphere's would be a helluva lot more expensive to build than fusion reactors.

  • @JohnMichaelGodier
    @JohnMichaelGodierКүн бұрын

    Depends on how many fusion reactors you want. If your energy needs are on the level of the output of a star then you're going to need millions of reactors and you're going to need a whole lot of fuel. The most abundant source of fusion fuel in a star system is the star. To stellar lift your fuel off a star, you're going to need a Dyson swarm of mining equipment. No matter what, you end up with some type of Dyson structure. This is such a severe problem that the Dyson swarm ends up the cheaper option. No fuel required, and no stellar lifting needed.

    I once read a scifi book about humanity’s first voyage out if our start system. In the story, once they crossed the point where they had left the solar system, everything went black, no more stars or anything to use to navigate. The scientist of the team soon realized that the entire universe had dyson spheres around every star but were projecting the universe into each star system. The dyson spheres were being used as cosmic scale computers to find a way to reverse entropy and prevent the end of the universe

    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.

    The problem I have with any species choosing to live on a Dyson Swarm is that you're giving up all the virtues of planets, not least comfortable gravity, to live in ultra-low gravity on asteroids. No mountains, seas, lakes, beaches, forests, tundra, etc. Come to that, no gravitationally bound atmosphere. Who would want to do this?

    I think our simple baby minds assume that advanced civilizations will automatically eventually make a Dyson sphere to harvest the energy of their stars simply because some authors wrote stories about that happening. Isn’t it equally likely that advanced civilizations will find other preferred methods for harvesting energy, or that they would develop technologies that wouldn’t require much energy? We are spending a lot of effort to search the universe for something that advanced civilizations may never need, because we have little baby minds.
