Did you say the ring would weigh a million tons? The earth is something like 6 billion trillion tons itself. If the space station weighs 420 tons then 1 million tons of material would only give you around 24000 space stations. The space station is a football field long, roughly 17. 6 space stations should make mile, so 24, 000 space stations would total 1363 miles which creates a circumference of 434 miles. That would still have to be multipled 16 times to encircle the moon, much less a sun far enough out not to bake.

Boy, the science here is TERRIBLE! So many things wrong it's hard to pick. My favorite two are it's weight (over a million tons) and the rotation speed. Both are off by many many orders of magnitude. The best part: they are off in different directions! The speed is waaaay over stated, yet the weight is ridiculously understated. This is just bad bad bad--not science, not engineering, not even close enough to count as a guess pulled out of your ass while drunk at a party.

it would take the whole economy of the world, until the end of time, to maneuver kuiper belt objects close enough to the sun to construct a ring world. Also, no known material would hold together under the rotational forces, because it must rotate to create artificial gravity and retain a breathable atmosphere. And finding enough gases to create enough atmosphere would require stripping thousands of earth-like planets. This is just never gonna happen, sorry!

We would have to build a massive tobar expanding ring shaped structure on earth and then with Nitinol in it's design it would expand on its own into the higher atmosphere where it can then be populated and we can see our neighbors down below and then further rings can be built on its outer edge to create a saturn rings pattern that can be inhabited for space habitation.

Only a billion tons of material to build a ring world around the sun? One estimate of the earth-s weight in pounds is 13, 170, 000, 000, 000, 000, 000, 000, 000. That is 13. 17 septillion pounds. I-m thinking the ring would weigh more than earth if it was 150 million miles in diameter - just sayin

For Humanity to create a Ringworld, there would have to be gigantic leaps in technology and resource gathering to make this work. and shitloads of time. by that time, we would have already charted most of the galaxy and found actual inhabitable worlds than to continue with such a project

-no less than a million tons- seems low by many, many orders of magnitude
earth's orbit (which would be the circumference of the ringworld) is almost a billion kilometers long. The ringworld would have to weigh a -kilogram- per -kilometer- to get that mass.

the ringworld is unstable; any perturbation in its position will not be corrected naturally and it will eventually drift away from its central star or even into the sun unless it is monitored and artificially controlled constantly

very happy to see the comments about the narrator saying the ring would weigh at least 1 million tons - wow, must have failed math big time - that structure would weigh a few planets and a couple of billion asteroids at minimum.

The asteroid bit is actually a moot point. The reason is that, by the time we are able to build such a -MASSIVE- structure, we would already have the means for decimating any celestial objects heading towards it.

Actually your wrong with it needs to spin fast cause gravity is caused by mass even NASA figured out that if two astronauts were floating around sooner they would float to each other

You could solve the problem of solar storms If you built It around a dwarf star Since there is no fusion happening in then Just left-over heat that lasts for tens of bilions of years

Bro if we build ring worlds like halo sh im down the unsc/oni can take me i mean even if this is liek 500 years later like halo(2552/2500s) ima ask god to send me down there.

The Kuiper Belt objects are actually very far away from each other - not nearly bumping into each other (just so no one thinks that this video is being 'scale accurate')

If you build this ring. We have to hear that annoying little robot called guilty spark who wants to activate the ring and cause destruction on a galactic scale

I think with this structure. It needs a holographic sheild which is impossible to make and much harder to construct it than the RingWorld

Would love to be free from poorly behaved people. We should just build separate mini planets so people can stop squabbling like little children.

If you could build it, you don't need it for living space. You don't need ships or worlds or Suns.
It's an example of -just because you can-.

Why would you build a supermassive ring world surrounding the sun when you can instead make a much smaller one orbiting a gas planet

The spin on Niven's ringworld had the material of the ring under something like 100 billion psi of tension.

We better start building new artificial and simple spacestation planets like earth instread of a big ring.
