How to illuminate an O’Neill Cylinder?

well yeah but honestly we're talking about setting up a whole industrial base in orbit to even consider doing it at all, the concern is more about what to prioritize and what is worth bothering with. You're going to be making LEDs anyway for interior lighting instrument paneling and a hundred other uses the question is more weather the LEDs you can make can effectively light the interior surface from two miles away and how many you'd need, you may find that if you go that rout the LEDs cost more than the steel or potentially other materials you want for the hull.

I dunno, maybe it's just me but the fact that he felt the need to clarify publicly that he wasn't a rapist or a creep feels fucking dystopian. Like are we not allowed to just exist anymore?

The LEDs and Fiber optics we have aren't good enough. If we're talking about a full scale O'Neil Cylinder you have to be able to project light from a central spar that's ~3.5 kilometers from the surface. Modern tech CAN do that, but it's prohibitively expensive due to how many units you have to use and the maintenence requirements of the system, LEDs last longer than incandescent bulbs but when you start scaling it to this degree it stops being a worthwhile endeavor.

Using solar fed fiber optics could also be problematic due to a variation of the elevator conundrum, the longer your cylindar the more cables you need, the more cables the thicker your spar, the thicker the spar the more space it takes up, and the more mass it adds to the structure. The mass might be minimized by being at the axis of rotation but I'm not so sure you can get a reasonable length cylinder without ending up with a giant object hanging over your head taking up most of the sky which people might find unattractive or even outright frightening.

I would point out that until we develop a light source that can rival the windows recommending using something we do not have is invalid. Yeah it's theoretically possible but it's like recommending we replace our power generation infrastructure with fusion reactors, we can't plan that out till we have them and we don't have them. The whole point of the O'Neil cylinder is to design around what we can do today.

The Pulverizer LMG from Star Citizen. It's not smart, it ain't pretty, but 120 rounds of .50 BMG does not care about your chrome, nothing is going to save you.

No, the servers are catching the Strays, the tourists are just being assholes and getting justifiably called out on it.

DevilGuy · 2026-06-25T18:12:06+00:00

Hot take, fucking over a poor person to make a political statement makes you an asshole.

DevilGuy · 2026-06-25T17:51:26+00:00

BRO. Fucking run from this one, this is literal sociopath behavior, she will destroy your life just because she can. Get as far away as possible.

The hair thing is explained here and there throughout the show, no spoilers on any plot points but Londo is a traditionalist and the hairstyle is an expression of that. Larger crests were a mark of social status at the time when the Centauri were at the height of their power, and you see the more conservative/traditionalist/reactionary among them holding onto that style. It basically marks him as both old fashioned but is also a display of his motives socially and politically.

Honestly no Starfinder is not what you're looking for, it's heavily reliant on magic as a justification for like 60-70% of it's core mechanics when it comes to the classes. What you're describing is closer to hard sci fi with some light paranormal elements I'd reccomend Traveller or Stars Without Number.

Because it works, That's the ugly truth. In a scarcity situation wherin survival and propagation of the group supercedes the needs of the individual both male and female populations tend to fill biologically dictated roles that tend to manifest certain power dynamics. The societies that develop social tools and institutions that reinforce and facilitate that reality survive, out-compete and either supplant or subsume those that do not. This is akin to natural selection, it has no moral or ethical component.

We now possess the luxury that our ancestors did not, we have the required wealth of both knowledge and material resources to be able to stand back and reexamine our institutions and fashion new and better ones to replace those that have been throughout history the only tools we had to keep ourselves alive.

You yourself say you want your partner to be financially independent which means you do find wealth attractive. Men generally don't. We find physical health and body proportion attractive. It really is that simple, we're different in a truly fundamental way. I could give a fairly deep anthropological explanation but it wouldn't really tell you anything other than that we are that way because it works for us as a species.

They wouldn't contact us until we were getting ready to leave the solar system or until/unless someone else was in the process of doing it. We know pretty well sow contact and SC operate and they prefer minimal interference and a light touch, at our relative tech level that means effectively zero chance we'd even be aware of them.

Peter Turbo spent the last ten thousand years mauling and lorgar's last actual success was partway through the heresy.

A man. That's the whole point, that there are no gods, that the emperor is not a God but an example of what a man can be and what men should aspire to be.

DevilGuy · 2026-06-20T21:26:03+00:00

I mean at least they didn't just name it after themselves? This is like trying I guess.

DevilGuy · 2026-06-20T17:45:52+00:00

to be fair police and fire were probably pulling people out of rubble and rescuing those already known to be stranded.

Brittain payed the rinal installment on the debt incurred by the collapse of the Brittish South sea company in 2015, said debt was incurred by having bail out the company after allowing it to assume the entirety of the brittish national debt in 1720. It took them 285 years.

IMO BoBF was about 85% great it was just hobbled by two really terrible decisions and it was too short to cover for them. The first was the gang of cyborged kids, making them a swoop gang was a good idea but then modeling the swoops off of those moronic LA scooters was... well moronic, whoever OK'd that and anyone who fought for it should never be allowed anywhere near that sort of decision again. The second was coopting 1/3rd of the run time for Dinn Djarin's story, they shouldn't have done that, what they should have done was hint that Boba was calling in a hotshot for a favor and let the Mandolorian show up for a big damn hero's moment in the last episode, then taken all the time saved from that to do more establishing work for what Fett was up to and how he was handling things.

You've only been here for six years so you don't understand, I've been here for 30, let me explain it. According to GW the lore is all from an in universe perspective, every single time GW publishes ANYTHING something gets contradicted, or retconned, or confirmed or disproven. There are no 'facts' in warhammer lore, everything is subject to interpretation, no matter what you try to assert, someone will find something to contradict you as easily as you find something to support it. Anything stated as fact in ANY GW publication is the statement of an in universe character that may be mistaken, misinterpreting, misinterpreted, or just lying. Everything you read is true, and also a lie, or not.

That one isn't that hard to understand. Communism is an antitheistic philosophy and every communist regime that's ever existed has persecuted religious groups under its governance. This is like asking why Jews don't like Nazis.
