  • Depends. The cheap houses, yeah, there’s as fair bit of noise, but you can’t hear everything. From downstairs, you can hear when someone walks across the room above you, but not when they’re walking in other upstairs rooms. And from rooms on the same level, you can hear if someone is talking loudly in the room next door, but not enough to make out what they’re saying unless they’re yelling.

    Well-built houses or buildings made for occupancy by multiple families usually have better sound insulation between the rooms/floors/units, so it’s not always an issue.

    Edit: the plus side to that is I know all the noises my house makes at night, so as a light sleeper, I know when something is wrong in the middle of the night, and I only need one decent sound system for the whole house, which is great for listening to records while doing housework.


  • So, one observer will see those oscillations happen faster than the other?

    Not quite. In each observer’s frame of reference, time appears to pass the same; it’s only when you try to reconcile the between two objects that are not at rest with respect to each other does relativity show up.

    Basically, when you bring someone back to Earth, the observers will find that their watches don’t match up even though both observers experience time passing the same way as normal (because the oberserver is by definition at rest with respect to their own frame of reference).

    TL; DR: Relativity is a pain in the ass and makes no sense in everyday terms.

    edit: disclaimer - I am not a physicist and have not taken physics classes in a decade plus, but I do teach science at a college. I’m going mostly on half-remembered lectures and some random one-off discussions I’ve had with my buddy in the physics department over the past few years.



  • It’s been a long time since I took modern physics, so I’m not positive, but I think you’re right that the moon would have time moving slower, and if your 50ms/day is right (edit: I based this on the moon traveling faster than the earth, but I don’t know anything about gravitational relativity, so that’s probably wrong) then you’d need to do something like skip a second every 20th day on the moon to keep pace with Earth. We could call it an “anti-leap-second”

    Programmers, that seems pretty simple; what’s the big deal? /s


  • No, the moon’s rotation isn’t on a 24-hour cycle. I’m not an astronomer, but I pretty sure since it’s tidally locked to earth and on a 28-day cycle around the earth, a lunar day is actually 28 Earth days, but I’m not actually sure how that would factor into the number of time zones (I’m pretty sure it would be more complicated than just 24 time zones to match 24 time zones on earth, though).

    Plus, I think the speed of the moon relative to the sun is different enough from Earth that you need to take relativity into effect, which is the real headache here.





  • The Expanse series went into a fair bit of detail on the “form follows function” aspect of spaceship aesthetics, but it was a lot more near-future than Trek.

    In most cases, The Expanse postulates that the most important aspect of spaceship design is cleanliness and the ability to protect the air filters and purification systems. In this case, I would assume that carpets are likely going to cause more of a headache than comfort, but who knows. Also, they’d probably want something that would not interfere with magnetic boots when the ship is in zero-g.






  • Straczynski also pitched and write one if the best comic miniseries of the early 2000’s, too. Rising Stars was limited by the style of art that was popular in comics at the time, but it’s one of the best, most cohesive stories ever to be seen in comics at that point. Frankly, I think it’s one of the examples of why comics started to be taken seriously as a storytelling medium, and it’s kind of a mystery why every other edgy early 2000’s comic got the Hollywood treatment, but Rising Stars seems to have been mostly forgotten. I mean, hell, if Cowboys and Aliens can get a major motion picture release and The Boys can be a massive hit, why can’t Rising Stars or Babylon 5 at least get some sort of animated series?
