I hope that in my life time, immortality becomes available. I want to be alive, or at least still conscious, in a thousand years when the light of these monsters being destroyed reaches Earth.

[Anonymous No.3660988]

The cruel thing is that immortality is likely to become possible in our lifetimes, but will probably cost too much for most of us to afford the necessary procedures.

Well, regardless of what happens, I'm going to tell my children to tell their children to tell their children ( etc. ) to unfreeze, revive and then augment my corpse before this happens.

I think a limit should be put in place for children.

If you're given life extending enhancements, you're required to be sterilized after your fourth child, or something along those lines.

Possibly growing pool of sterilized undying people + pool of not sterilized people reproducing at a the same rate as today = demographic explosion

Sorry bro but that is going to make overpopulation in the seriously bad sense a very real possibility.

It'll have to be less until we figure out how to mass-produce near-c spaceships, or a Dyson ring.

Oh you.

It's also known as a ringworld, a hypothetical superstructure in which a ring is built around a star, made to rotate for artificial gravity and then materials required for the sustainability of life are added, water, air and so on.

That's fucking awesome. So it would be kind of like that artificial moon from that one cartoon movie where they're space pirates and the guy has a rocket powered hoverboard and they get treasure n' shit.

Oh my god I loved Treasure Planet so much.

Montressor spaceport.

But a Dyson ring is MUCH MUCH larger. Montressor spaceport is more of a thin version of an O'Neill cylinder.

I'd love to be able to be alive when mankind has the power and resources to create a life-sustaining superstructure that's home to billions in outerspace.

The Ringworld is like a ribbon of land, that's been put in Earth's orbit around the sun.

It would have a surface area about three million times the Earth's.

This is the classical view of it, showing the inner-orbiting shadow-squares, which give the ringworld a day-night cycle.

The thing is spinning fast enough to keep an apparent 1g surface acceleration due to centripetal force.

The thing is open to space, with only the acceleration keeping the air on the ringworld, between the 100 kilometer high sidewalls.

There are two extremely large seas, one in which there are several 1-to-1-scale maps of earth-size'd planets.

Just to give you some sense of scale.

A good youtube video that shows the scale of the ringworld.

I would say that materials with the tensile strength required for an O'Neill cylinder are nearly here. Then it's just a matter of having an affordable construction technique for such a structure, which I've outlined in the other thread I'm active in relating to the profitability of space. Not to mention life extension:

The only problem is that the materials for a Ringworld are next to impossible to produce, unless you spend a few subjective millennia studying nuclear physics with a vengeance and discover something like the magmatter in Orion's Arm.

Seriously now, a much better way to go about doing this is by having a set of swarms in orbit around the Sun (Statites would have to reflect far too much sunlight to stay afloat, which could be used for computation).

But I still like the small <1000km wide habs like O'Neill Cylinders and shit. Thousand kilometers is the limit of Carbon nanotubes, I think.

Isn't there a much higher danger of space rocks hitting and destroying large chunks of your space ring than earth?

[Inurdaes !V1sPhobos. No.3661353]

Personally I prefer the concept of O'Neill cylinders more, as they're far easier to migrate.

If it survives spinning fast enough to get an Earth gravity on the Sunward surface, it can probably survive meteorite impacts.

I want to how how well it fares against relativistic rockets.

well for first world people at least wouldn't this not really be a problem? Couldn't a program be set up where people get a lone and pay it off over 10 thousand years or so? Sure you would be crippled for debt for millenia but you would still live forever.

The Niven ringworld was protected by an automated system that used artificially-induced solar flares as a lasing medium and blasted any object which had a trajectory that intersected with the shadow squares or the ringworld.

Also, the construction of the ringworld pretty much depleted any and all solid objects in the system, with even non-usable elements getting transmuted to usable ones.

Still, in the first book, there were two punctures. One that had punched through from the inside and one from the outside.

The one that punched in from the outside left a hole the size of the moon with the sides punched up into a mountain, higher than the atmosphere.

The one that punched out from the inside left a huge hole and a resulting hurricane. But as big as the hole was, the Ringworld was big enough that it would have taken at least hundreds of thousands of years for it to cause a life-threatening danger.

And yes. The Ringworld was created from the sufficiently advanced material "scrith", which was as strong as the nuclear force. Also it was able to stop something like a third of all neutrinos.

True, but what if it requires some kind of process or material that is inherently obscenely expensive so that the cost would be justified? There's no real way to make thousands of hours of therapy done by experts in the field inexpensive.

[Anonymous No.3661678]

also the ringworld wasn't in a stable orbit. it couldn't be in orbit and provide artificial gravity at the same time.

That's why something like a Halo or Culture orbital makes more sense. They also do a better job of providing for day/night, and potentially even seasons.
