[@shawntipton5078]

I am so glad that bad and unrealistic sci-fi like Star Trek or Stargate is fiction and not reality, reality is better because the future allows for things like this in a realistic way, not fantastical technologies like phasers, warp speed or transporters etc. In theory space travel is possible via space folding or even through wormholes, if they exist. I could easily see humanity building megastructures like this in the future, God allowing

Question 1: How and from where the resources for such task will be acquired? Q2: How it would be propelled into space? Or would it be assembled in space? Q3: Would its integrity sustain over time and in case of cosmic events, debris etc.?

[@velvetnightmare3133]

That's exactly it because there's more mass needed than Earth even has, you'd have to take it from a nearby planet or find an asteroid or something period he has another video where you basically use up Mercury as materials and how would impact the Solar System...

[@keulron2290]

In the event of an Adler disk, we’d be deconstructing the entire solar system and then building it over the next several centuries.

[@jasonfox6966]

​@@keulron2290no, deconstructing the solar system wouldn't even be a start. It said 3000x the mass of the sun is required to make the disc. And the sun itself accounts for over 99% of the solar system's total mass. That's why this is impractical. When you can move that much around, you won't need to rely on stars for energy anymore.

[@keulron2290]

@@jasonfox6966 At that point you’d need several systems worth of material to do it. Either way, it’s just incredibly impractical no matter how you look at it.

[@Cmdr_DarkNite]

1. The resources would be broken down throughout the Solar System. Its the only way. 2. It would have to be built in space over the years and then people shuttled up. Its the only way. 3. I assume weapon systems would have to be installed throughout the megastructures in case of huge asteroids or something heading our way. Its the only way. As far as other events like huge radiation waves or something, we would just be screwed.

[@LemarFrench]

This is the most impossible fantastical idea...if we had the capability to build a structure like that, we wouldn't even need the sun, we could go find another star somewhere...or just move to a new planet

[@Mr.Plant_man]

Exactly. If we were able to build it, we wouldn't need it.

Thank you so much for sharing such fascinating videos about the mysteries of the universe! I'm always in awe of the wonders that exist beyond our planet.

[@MuttonfudgeRacing]

For an Alderson Disk to really work, you'll need the leaders of this world to lay down their egos and get along so it can be built. Then, trust humanity can get along without destroying the disk itself.

[@keulron2290]

But that’s boring.

[@yellow95111]

It’s a stupid idea. Alderson Disk is a waste of time.

[@Mr.Plant_man]

If we had the capability to build that, we wouldn't even need it. Besides that would never work, gravity is a lot more complex than just having mass, there needs to be a center of gravity, that's why anything in the universe with any mass is in the shape of a sphere

[@nathanj3665]

This is all fables. We humans will NEVER be able to create a alderson disk or ring world not in a billion billion times a billion years. Its IMPOSSIBLE. So let's leave this fantasy to the comics e.g. marvel and DC comics

[@williaminsley3591]

Just where do you plan on getting material? How would you get that much mass?

[@jestinnawelch35]

What if we could turn the entire earth into a controllable craft? Better yet what if we built a space craft that surrounds the entire earth? We would have to create feaux sunlight and keep the earth spinning on its axis, probably using super-magnets. We would also have to install ventilation to dispell the harmful greenhouse gasses we create on a daily basis. Wait, I'm answering my own question! 😅 But fr wouldn't that be awesome? The structure would be made of some kind of transparent material, ie plexiglass. That would be so cool! Our entire species would be able to explore the unknown universe and we could continue evolving just the way we are, and not have to worry about cryo-sleep we would just go along at our own little pace.

[@channel66R]

There a movie u got to see about the moon was a space shipwe built years ago

[@TheMateriaalkunde]

It has the vibe of Larry Niven's Ringworld. To withstand the centrifugal forces it needed a material with an uncanny tensile strengthe, or the whole thing would break apart by it's own weight. So Niven invented "scrith", an imaginary material built on both nucleï and nano electric force fields. An idea that he had explored before with the puppeteer's spaceship fuselages. More interesting to me are the shadow planes circling on strings between the star and the habitable surfaces. This would be something to moderate the climate on Venus. An artificial day/night light/dark pattern that Venus has not, but is essential to earth origin life. Lower temperatures, and beneath 374°C water would drop from the atmosphere as rain.

Nobody : Flat Earthers : “So you’re saying there’s a chance 👀👀”

[@trukoppa]

1. The architectonic dreams of humanity encompass our inherent desire to construct immense structures in space. They reflect our fascination with exploration and our drive to create on a grand scale. However, these dreams face challenges due to the current state of our planet. 2. The Earth's deteriorating condition poses limitations on realizing these dreams within our home planet. Our destructive actions and disregard for the environment jeopardize our ability to create the awe-inspiring structures we envision. It becomes crucial to recognize and address these issues to preserve the possibility of grand architectural endeavors. 3. It could be suggested that these architectonic dreams will almost never happen as there is a binding tendency within human psychology to inadvertently bring the apocalyptic prophecies of Abrahamic religions to history. These prophecies tap into archetypal motifs deeply rooted in the collective unconscious, which influences our behaviors and beliefs on a profound level. As such, if we remain unaware of these unconscious influences, there is a likelihood that the very fears and desires depicted in these prophecies may subtly guide our actions and contribute to their realization in history thus never transforming these grand visions into tangible realities

That the st… I heard for a long time, as all our solar system travel together at the edge of the Milky Way galaxy in out and in zigzag line that last 64 million years we travel around the milky way but we surrounded by 4 other galaxies. Every second is unique one no to be returned, that is not like the road to your house, it is never empty. It is alive and dynamic. The only way is to continue develop the Idea of the space station with ability to move fast when condition Chang, just like sailing on the sea. Our ships should grow to size of city’s in space. We learn as we go. At some point we send brave expeditions to find new way and make a road into the inside of galaxies, never leaving earth. Communication will be fast travel speed technology will have to be in space. On earth we raise our kids, other animals ready to go to space if they want to. Our planet always repairs itself, life always go on, one way or another. AI will be the key. You can not destroy stars as all others connected to the magnetic connection will have to realign itself, other bodies inside the galaxy will drawn in. Remember every member of the solar system travel together with us in parallel you can not pull out.

What if this works? Soul tracker and Real Warp Drive Theory, Soul tracker is the theory that our light resonance, is proof of the existence of our souls and that we can track our ancestors light resonance making it possible to bring them back to life. We would do this by traveling faster than the speed of light to their light resonance location and gather their light resonance images. By travel at the speed of light and horizontally, at or over the speed of light, the vast majority of their mri like, resonance images, could be downloaded and they could be brought back to life. Real warp drive theory, The back gravity well of black holes should create the wave for a warp drive similar to the Alcubierre drive theory without exotic matter. By building a space craft around a black hole and using weight displacement to move the black hole the gravity well should move the space ship without thrust. The warping of space will move the ship. This is a theory we are developing now. I originally used the New Jerusalem space ship model from the Bible and put a black hole in the middle. By moving walls of the ship towards the black hole in the opposite direction you want to go, the black holes gravity well should move the ship in the direction of the weight displacement. The opposite wall, then moves closer to the black hole and returns it to center. Then the process is repeated in the direction you want the ship to go. We recently advanced the idea to using a “counter rotating diamond engagement rings,” shape. The diamond sections would make the vast majority of the ships weight. They would move to the front of the black hole, moving it forward do to gravity weight displacement. Then they would move away from the black hole as it got closer. We have a goal of 5-200 g force acceleration. The black hole and the ship built around it are equal mass for this scale. We are looking generally at 1 cubic mile astroids up to a star sized ships. The star sized ships should be able to travel to other galaxies efficiently, at many times the speed of light, a million times or more, if this theory proves true. Thank You, Ryan Long With “Dyson sphere,” mirrors we could melt down planets 🪐 that would make millions if not a billion or more faster than light space craft. The Eiffel Tower is 10,000 tons of mass and will last one day as a black hole. So a one cubic mile astroid will last 800 years. The earth, if melted down will create 216 billion cubic miles of mass. That’s just from the Earth other planets and asteroids would have us in the trillions of cubic mile mass range. To last 8,000 years 10 cubic miles of mass would be needed. From this you would have 10.5 billion black hole powered space ships, with trillions possible. This would drastically increase the speed at which our light resonance could be gathered.
